Shinya Hīragi

Shinya Hīragi (柊 深夜) is a supporting character of Seraph of the End: Vampire Reign as a member of Guren's squad. He is a Major General of the Japanese Imperial Demon Army. He was chosen to marry Mahiru Hīragi and was adopted by the Hīragi Family. Although he has high capacity of spellcraft from since childhood, Shinya is not comfortable about being with the Hīragi family. However, he is good friends with Guren Ichinose, who also holds the same intention against them.

He is one of the main characters in the Seraph of the End: Guren Ichinose: Catastrophe at Sixteen light novel series.

Appearance
Shinya is a tall, young man with medium length white hair with bangs and blue eyes.

Catastrophe
He wore the First Shibuya High Uniform, a black with a standing collar, with red trim which was also around the cuffs. The school emblem was located on the left breast.

When Guren squad is first formed, he wore the standard JIDA uniform which consists of a long-sleeved black jacket with two rows of gold buttons on the front and red details including the. A brown Sam Browne belt passes diagonally over his right shoulder and holds a brown pouch on his left side. Along with that, he wears a pair of white gloves and a red standard belt. He also wears the uniform trousers with knee-high black boots which goes over his trouser legging.

Vampire Reign
He sometimes has his left fringe behind his left ear during the midst of a skirmish on the battlefield. In the anime, his hair is shown to be more of a silvery color than white.

He wears standard JIDA uniform, but is slightly decorated to show his rank as a major general. He now has an worn on the right shoulder with a crescent moon decoration and four badges: the first three are stripes with the top being red, the second being white stripe, and the third being a green, red, and white; and below that is a gold badge with the Hīragi crest. Along with that, he wears an armband on his left arm, a white web belt with a gold waist-plate, and black shoes instead of the knee-high boots.

Personality
Shinya is shown to be a gentle and cool man. He does not get angry easily, even when being insulted by Seishirō. He is seen smiling pleasantly all the time, even in tough spots, shown in the battle of Nagoya with Crowley. He has a lighthearted and breezy personality, often joking around Guren, and seems to be relaxed even during missions, as seen where he calmly teaches Yoichi the role of a sniper.

Shinya is shown to be very loyal to his friends, such as joining Guren in the battle in Nagoya, despite recognizing that it is a suicide mission. He is shown to put a lot of trust in his closest friends, such as Guren, and is deeply shocked when Guren is revealed to be a Namanari. Along with that, unlike most Hīragi, he lacks any superiority complex, as he has been seen to treat others kindly and politely. Another show of this was how he never shunned Shinoa unlike any other member of the family, as he treated her kindly and even seemed to truly care for her, aiding in saving her during the Apocalypse and later on forgiving her rescue of Mikaela. Shinya also holds his morals firmly above his desires, being deeply enraged at Guren when the latter killed many of his own comrades and showing nothing but disgust at Guren's nonchalant dismissal even as he justified it as being to fulfil both of their dreams.

A trait that Shinya possesses is that he is very observant and perceptive, picking out tiny reactions on Guren's face and is able to easily grasp the latter's emotions. He also is able to piece together an idea on what Guren is hiding just by observing his movements and facial expressions.

However, Shinya's lighthearted personality and his charming smile is only a facade, a defense mechanism. Since he was put in an arena-styled environment as a child, where young boys have to battle to death, he began to mask his fears and insecurities in order to help him endure the harsh training. Shinya's constant smile is also there to fool adversaries into letting their guards down, so he could strike at the right moment. Once his mask is gone, he is shown to be more blunt and even somewhat masochistic, thinking about how his own death will play out when Mahiru rejected him.

In the light novels, Shinya is shown to be a lot more ruthless and even sly, due to the harsh upbringing he received as a child where only the fittest child is allowed to live. He is not afraid to kill civilians or use dirty tricks, as shown in the the qualification exams when he spars against a fellow student. His high perceptiveness also allows him to see through Guren's facade of being a weakling. Despite the difference between his family status and Guren's, Shinya is still willing to become his friend and even help him achieve his goals (of overthrowing the Hīragi family); however, that time did not come to pass due to the Apocalypse.

Prior to meeting Guren, Shinya doesn't know what his purpose in living is, as he only lived to become Mahiru's mate to provide superior DNA for her child. After meeting Guren, Shinya found himself both envious and admiring of the former's goals and determination to live, and as he interacted more with Guren, Mito, Goshi, Sayuri, and Shigure, he found a new purpose in his life: to protect his new friends.

History
Shinya was a student at one of the Order of Imperial Demons' many kindergartens throughout Japan. He was then selected, alongside several talented children, to be the potential mate for the heir leader of the Hīragi Family, Mahiru Hīragi as the Hīragis to sought keep their bloodline strong. Shinya was never allowed to go home ever again, and his childhood days were filled with training and fighting where failure to distinguish himself among others meant death.

One day, he was singled out from the other candidates and was adopted into the family and engaged to Mahiru while the rest of the candidates were killed. Upon meeting her, Mahiru instantly told him that she would never love him, as she already had someone else. As a result, the two decided to pose as a couple until Mahiru could be with the one she truly loved.

Shinya was sparring against Seishirō within a spacious arena with Mahiru, Kureto and Shinoa observing. Whilst he avoided Seishirō's weapon the force given off knocked Shinya into the wall. Hearing Shinoa nearby ask whether he was embarrassed since it was obvious he held back Shinya picks up that she noticed. With it the case Shinya says he did it perfectly then since he is an expert at holding back. Told that he was brought here to be Mahiru's fiancé and that is the only reason why the family is keeping him Shinya jokes on whether he is a pet then if Shinoa wants him to bark for her. Shinya mentioned to Shinoa that Mahiru was already in love with someone. He is really curious about him largely since Shinya wonders what kind of guy could get that monster of a genius to fall in love with him. It was uncertain whether he bore any true affection towards Mahiru, though he was somewhat jealous of Guren for having Mahiru's love prior to meeting him in April 2012.

Events of 2012
Shinya first appears welcoming Guren Ichinose to First Shibuya High School by attacking him with a lightning spell before walking nonchalantly into the school building. During homeroom class, Shinya arrives late and chooses his seat in the back next to Guren. Shinya then tries to converse with him, and he reveals that he saw through Guren's attempt at trying to hide his true strength that morning in which Guren says he did that to not cause trouble. Shinya is unconvinced and tells Guren that he wants to bring down the Hīragi Family.

A few days later, the students spar against each other, and Shinya hits Guren so hard that he breaks several ribs, coughs up blood, and loses consciousness. Later on, Guren’s submissiveness to Seishirō Hīragi makes him lose respect from everyone in the class, including Shinya and Mito.

During the qualification exams, the Brotherhood of a Thousand Nights attack the school training ground and kill many students and teachers. Guren and Shinya fight Saitō and learn that Mahiru betrayed the Hīragi Family.

After the Order of the Imperial Demons announces it put down the "terrorist group" that attacked them before, the school reopens. Shinya helps Guren get drenched in cola again when Shigure nearly stops the attack.

A month has passed since the Thousand Nights attack, and Shinya tells Guren that the Hīragi Clan know that the Thousand Nights attacked the school and are now at war with them. After some insults Shinya takes no offense to, he then tells Guren that the Hīragis have started an internal investigation, hence they are unaware of Mahiru's betrayal; and the investigation is being lead by the student council president, Kureto Hīragi, and Guren is his number one suspect as Guren has a motive against the Hīragis as well as being able to survive the Thousand Nights attack... and informs Guren that Kureto is watching them from the school building. They both attempt to fool the student council president where Shinya shoves Guren to the ground.

Three days later, Shinya, Mito, Norito, and Guren to leave to continue their examinations in the gym. When Guren arrives for his bout, Kureto questions him about the Thousand Nights and then attacks him with the intent to kill, forcing Guren to fight seriously.

Later, Guren, Shinya, Mito, Norito, Sayuri, and Shigure report to Kureto’s office, where Aoi Sangū lets them in. Kureto orders them to investigate Ueno Zoo. Guren leads this new team.

The squad enters Ueno Zoo and battles a tiger chimera made with genes from the Four Horsemen of John. The creature wounds Guren, and Shinya notices his internal conflict to either listen to them or not. When he eventually agrees to retreat, A girl's voice is heard before Mito, Norito, Sayuri, and Shigure get knocked out while Shinya is able to dodge the attacker's strike... but ends up in strangle hold. The attacker is revealed to be Mahiru, and Shinya tells her that he wants to know what's going on so he could help her, but Mahiru refuses and chokes him into unconsciousness. At some point, Shinya regains consciousness, but pretends to remain knocked out to listen in on Mahiru and Guren's conversation. It wasn't until Mahiru is ready to leave with the chimera half does Shinya act by setting up a barrier around Guren and Mahiru with dozens of fuda. While Guren lunged at Mahriu, Shinya used the fuda to bind her legs, but Mahiru easily breaks out of the snare and the barrier, but gets caught off guard by Guren slicing off a piece of the chimera.

After Mahiru gets away, Shinya picks up the chimera piece Guren sliced off: the tip of its claws, and Guren demands for him to give it back. Shinya smiles and asks if Guren still wanted to fight given his beaten up condition. He then reveals that it was just an illusion, and used another to go behind Guren to toss the claw tip back to him so the real Shinya could revive the knocked out squad members. When everyone is gathered around Guren, Shinya tells him with praise that he could never be like Mahiru as if made the same choice she made, they wouldn't be trying to save her in the first place.

A month later, Shinya is called by Guren from Aichi Prefecture, who hung up on him before immediately calling back from a different phone number. Knowing that its about the chimera piece since Guren doesn't have it with him, Shinya tells him he has hidden it, but Guren would have to return to Tokyo to get it back. He then Guren him that Mahiru betrayed the Thousand Nights, and the organization contacted Shinya to know if he had any information in exchange for info on cursed gear and the chimera. When Shinya tries to encourage Guren in taking up the Thousand Nights' offer, Guren hangs up on him. When Guren returns to class ten days later, Shinya welcomes him back and tells him that a war has been brewing.

During class, Shinya sidles over to Guren and begins whispering to annoy him. He then passes a note to Guren revealing that the Thousand Nights is planning to meet at 2:00 a.m. the following morning at the tennis courts in Higashiosaka Park causing Guren wonders whether he can trust Shinya. They begin talking about Mahiru, and Shinya says he admires her and is jealous of Guren. Guren carefully pockets the note while being sure to preserve Shinya’s fingerprints. After class, Kureto calls Guren. When Shinya asks if that was Kureto, Guren says it was his girlfriend, causing Mito to become even more flustered. Guren walks off without explaining the joke, but Shinya takes pity on Mito instead.

In Guren's condominium, Shinya is defeating Mito at shogi while Goshi and Guren watch. Although none of them knew how to play shogi, Goshi insisted on them buying a cheap game from the convenience store. They played in an elimination-style tournament against each other. Goshi handedly defeated Guren in the first round, and Shinya is winning the second. As it turns out, Guren felt drained at the start of his match and lost on purpose, delighting Goshi and causing Mito to comfort him. However, Shinya realized it, annoying Guren evermore. When they tease Mito, she tells them the TV is distracting her.

The newscast shows the fire of a burning building as mud and bricks explode. A disheveled woman in her mid-twenties with long, silky black hair steps out of the crowd and screams for Yūichirō. A firefighter tries to calm her as she waves her arms, but she hits him. She holds a lighter and screams that the fire should never be put out. She screams about a demon child, who needs to be killed immediately. She pours petrol onto her clothing and has trouble igniting the lighter. Firefighters tackle her. Saitō then appears and approaches the camera. The footage at the scene cuts out.

Mito and Goshi turn back to the game. Mito surrenders. Since Mito is hungry and Shinya has things to do, they decide to continue their tournament next time. The three of them leave, and Guren picks up the phone Shinya left on the ground. Shinya left a funny message for Guren on there, but the phone did not contain any useful information. Shinya rings the doorbell, and they chat again. Shinya glances at the TV screen. Guren says they should not go investigate since it is too dangerous and they need more information about the fire first. Shinya tells him to not lie to his comrades, and Guren informs him that Shinya is not his comrade. Mito and Goshi come for Shinya, and the three leave again. There are no additional news reports on the fire, suggesting that the Thousand Nights censored them. Guren arrives at Hikarigaoka Park at 1:30 a.m. the next morning, shortly before Shinya. They sneak into the park and get into position to watch the tennis court. They see eight trained Thousand Night men in suits. The men yell something and then get into battle formation. The men launched chains from their bodies at their attacker, a non-noble vampire based on the clothing, who easily avoids their attacks while decapitating three of them and drinking the blood of the third. Within seconds, the vampire kills the rest of them.

When the vampire glances at Guren and Shinya, the two immediately race to their motorcycles. Guren runs his motorcycle into her, but she easily catches it and pops its tire. Guren swings his sword, and Shinya grabs him as they flee. They crush a taxi, and Guren throws exploding tags at the pursuing vampire. One blows off her foot, but it rapidly regenerates. She ignores the fact that her clothes are on fire and continues to chase them.

Despite going as fast as they can, she easily catches up to them. Guren cuts off her hand, which causes the vampire to end her pursuit of them. They dodge around traffic but break a rear view mirror, which hits Guren in the forehead.

Since she is no longer chasing them, Guren tells Shinya to slow down. Shinya says they will be arrested if he does that because Guren is waving a katana around and not wearing a helmet. Guren says he does not want to die because of inferior driving ability, so Shinya eventually slows down and they pull into an alley. Guren thanks Shinya for saving him and says he trusts Shinya a little more. They split up to head home.

The next day, Shinya sleeps at his desk until he starts playing shogi with Guren. He wins three out of seven matches against Guren until they are crushed by another student who is skilled at shogi.

When Mahiru calls Guren during his meeting with Kureto and Shinoa, she broadcasts the conversation over the whole school and makes Kureto out to be the culprit of everything occurring thus far in Catastrophe. Shinya meets Guren and Shinoa once Kureto releases them, and he and Shinoa laugh about Shinoa’s torture makeup. When Shinoa requests money from Guren to go home, Shinya gives her 10,000 yen. He tells her to ask Mahiru if she remembers who her fiance is.

Late that evening, the Thousand Nights attacks the school. Guren calls Shinya and informs him that he had sex with Mahiru, is accepting the demon, and is going to school to save his comrades. Guren calls him an idiot. Guren says he will leave Mahiru to him if he dies. When Shinya asks he means for Shinya to marry her or kill her, Guren hangs up.

Shinya engages the Thousand Night members in battle on the streets of Hachiko, Shibuya and cuts an assassin’s throat. He calls Kureto and reports. Kureto orders him to come to school to lead his squad members. He says the situation is to kill or be killed but little is known about the enemy. Tenri Hīragi is assuming command to negotiate the situation. When Shinya says he no longer has any value since his fiancee betrayed them, Kureto tells him to make his stand with the Hīragi. Shinya is surprised that the state of war is bad enough to give merit based on achievement rather than on birth hierarchy. He asks Kureto if he as some kind of goal, and Kureto says he lives to guide the Hīragi and gain power and privileges for them. He sees people as empty shells molded by their environments. He says Shinya needs only to submit to him.

Shinya steals a motorcycle from an innocent passerby and drives through the chaos to First Shibuya High.

When he arrives Shinya fires missiles of powerful talismans at Guren and allows Goshi and Mito to flee. The soldiers keep firing the talismans at Guren, and he retreats into the audiovisual room. The talismans cover the balcony and then the keep firing in order to seal him within the school.

Using a heat detector, he notices that only three people are left in the building. He watches Goshi carry Mito and escape while Guren, who is possessed, follows them. Shinya yells at Guren to distract them, and then his soldiers fire talismans at him to subdue the demon. In exchange for saving Guren, Sakae says he will hand over the Ichinose’s research to the Hīragi and will accept any punishment. Kureto then calls Shinya and lies about going to Aichi.

In the classroom, Shinya arrives with Mito, Goshi, and nine other soldiers; all have demonic blades equipped to them.

Noya wakes up, demanding murder.

Shinya, Goshi, Mito, and Guren struggle against Noya. Thanks to the cursed gear, their injuries heal unnaturally fast. Shinya tells Noya that the humans have already found a way to turn demons into their slaves. They fight, and Goshi uses an illusion to distract Guren while Shinya pastes a weakening talisman on Guren's neck and hugs him. The troops pierce Shinya and Guren with wooden stakes, and chains wrap Guren to Shinya from the feet on upward. Guren loses consciousness.

Over an hour later, Guren opens his eyes in the classroom but is too embarrassed to start talking right away. Shinya teases Guren about thanking him.

Guren asks about the cursed gear research and the Thousand Nights' movements. They chat a little, and Guren and Shinya reveal to Mito that they were fighting over a girl. Guren says he won, but Shinya says Guren got dumped afterward.

It is September 2nd, and Mito, Shinya, and Goshi play video games at Guren’s apartment until Mahiru shows up. Guren attacks her, and they fall from the twenty-fifth floor. Mahiru stops her fall by using her sword. Guren is badly injured but recovers.

Guren and Shinya play Bomberman while elbowing each other. It is now 3:30 a.m., and Mito and Goshi have both fallen asleep. Everyone starts waking up, so Sayuri offers to make them supper.

It is the night before September 29th. Mito, Goshi, and Shinya visit. They heard Guren's yelling. Shinya warns Guren that he cannot save Mahiru. They discuss how they can kill Mahiru. Guren shows his friends the documents he took from Mahiru's apartment. They list the children involved in the Seraph of the End experiment and prophesize the destruction of the world. Guren says Mahiru was taken by vampires on the Metropolitan Expressway and mentioned the vampire queen in Kyoto. Shinya asks if vampires have a monarchy since they have very little information on vampires.

Shinya tells Guren he shared that information too late. The group is aware they are being completely manipulated by Mahiru.

Kureto visits Guren and orders him to kill Mahiru within forty-eight hours or else he will kill Guren’s father and the rest of the Imperial Moon. He calls Aoi, stating that Guren betrayed them and cut him down. He orders Sakae’s death, but this is all a ruse.

Guren and his group escape to the roof and steal Kureto’s helicopter before heading to Kyoto. They crash in the mountains. It takes them a few hours to descend. The boys have a peeing contest.

They pull out a map and compass and plan to buy civilian clothes more suitable to their situation than skirts and court shoes. They plan on taking the shortest route since they figure the supposed vampire settlement will prevent the Imperial Demons and Thousand Nights from hunting them down so easily in their territory.

They group comes across a truck, and they discover that each of them has been trained to hot-wire vehicles. Goshi starts up the car immediately, impressing Mito with his skill. Guren and Shinya notice that the owner left the key in the ignition, but Mito does not notice and keeps praising Goshi's skill. Guren naps while chatting with Noya. The others keep a lookout since they say it is impossible to sleep in the loud and shaking truck.

Guren wakes up on the truck with Shinya watching over him. He slept for seven hours, but no one wanted to wake him because he was talking with his demon. Goshi and Shinya have been taking shifts looking after him.

They enter the love hotel where the others are resting, and a pair of students in sailor uniforms mistake Guren and Shinya for a couple. Guren puts on the news and changes into civilian clothes. Suddenly, Asuramaru drops down in front of Guren, but Shinya quickly knocks it away before Guren comes into contact with it.

Guren tells his friends that this is Mahiru's sword and says he did not realize he had it.

A vampire breaks in through the window and tells them not to move. Guren summons Noya and performs a more powerful attack than he has ever performed before. She catches his sword in her mouth.

Guren orders the squad to use a retreating formation with him as the sacrifice instead, but Shigure and Sayuri attack the vampire instead of retreating. The vampire catches their weapons and comments that they are quick. She mentions that Lady Krul Tepes told her about humans creating second-rate weapons. They struggle against her, and Guren meets with Noya.

Mito appears in front of Guren and is stabbed in the chest. She coughs up blood from a fatal wound. Looking back at him, an expressionless Mito tells Guren they're using the Tenka Formation. Guren realizes this is not Mito but rather one of Goshi's illusions.

Using the illusions, Guren cuts the vampire in the neck. The vampire is unable to defend herself in time because Shigure placed talismans on her sword and detonated them. Shinya appears from behind, cutting off her sword arm, and Mito sends the arm flying into the hallway. They continue fighting, and the vampire wonders why her wound will not heal. She turns to escape through the window but is stopped by an illusion of a wall. While she is distracted, Shinya cuts off her feet. Guren stabs her through the chest.

After Guren's father, Sakae Ichinose's, execution, Shinya calls and offers to clean up Sakae’s body, but Guren asks him to come to his apartment and play games instead.

Several days later, Shinya visits Goshi, and Mito sneak in to visit Guren.

When Shinya calls, Guren says Shigure accidentally cut off her arm while attempting to chop up a radish. When Sayuri calls, Guren orders her to clean up the room coated in Shigure's blood. They meet at Guren’s apartment that night, and Guren informs Kureto about Saitō. Shigure’s arm is successfully reattached.

When Guren heads home, Seishirō attacks him with a group of ten soldiers, but Guren is simply relieved it is not a vampire. Seishirō orders Guren to kneel down, but Guren refuses. Seishirō picks a fight, and Guren finishes it. Shinya prevents Guren from landing the final blow. Shinya convinces Seishirō to leave Guren alone.

The usual group meets at Guren's apartment, sans Shigure, who is still being treated. Guren tells them what happened. Then, they eat curry and play more games. Mito owns them at Bomberman once again.

On December 10th, the high school students are using demons, and one goes berserk. Kureto sends Guren, Shinya, Goshi, Mito, Sayuri, and Shigure in to kill him, and Guren is the first to arrive. He comes across a classroom with twenty-seven corpses, and a girl missing an arm and leg comes out, chased by a boy with black eyes and curse markings all over his skin. Guren knocks him out instead of killing him.

Mahiru appears, applauding Guren's strength. She admits this is her doing and does not care about the victims. She asks about the experimentation on Asuramaru. Humans must undergo surgery in order to meet qualifications to use a Black Demon, but the current success rate is less than 20%. Most people die. Although Kureto, Shinya, and Guren had successful surgeries, Goshi, Mito, Sayuri, and Shigure did not even meet the basic criteria to have the surgery done.

Guren says he wants to protect both her and his friends. He asks her to surrender, so they can extract the demon from her. Guren has Noya possess him, and they fight. He now knows the strength of the demons and believes he can defeat Mahiru, but he has yet to realize she is now a vampire. The rest of the group arrives and fights her. She manages to escape.

On December 23rd, Guren takes Shikama Dōji to meet with Shinoa. The traitorous faction attacks them, but Guren kills them quickly and incidentally drenches Shinoa in their blood. Shinoa loses consciousness as soon as she touches Shikama Dōji, but Guren manages to escape with her.

Goshi calls Guren and reports that Guren's apartment was set on fire by the traitors. Their phone call is interrupted. Guren steals a motorcycle and escapes, but a van chases and crashes into him. Traitorous soldiers face him, but Shinya attacks with Byakkomaru while pulling up on another motorcycle. Goshi arrives in a stolen minivan with the rest of their squad and picks them up. He says policemen are still chasing them. They ask Guren what they should do about the end of the world.

Guren calls Mahiru and says he will betray the Hīragi and join her. She laughs.

Second Shibuya High Arc
Shinya is first seen during a meeting among the top-ranked members of the Japanese Imperial Demon Army. He contributes little to the conversation apart from trying to smooth things over between Guren and the other generals.

Shinjuku Arc
Shinya arrives with Kureto and the Shibuya Main Army as reinforcements in the battle at Shinjuku. Shinya is the first to appear, sniping at Ferid. Unfortunately, Ferid notices his presence. Alarmed, he dodges, but he sustains a minor injury to his left shoulder.

Post-Shinjuku Arc
Shinya reappears with Kureto and Aoi for Yūichirō's "interview." Shinya warns Yu not to trust Kureto right before Kureto cheats in their fight and beats Yu handily. Kureto orders Shinya to attack Yu. Shinya tells Kureto that unlike him, he doesn't like to pick on the weak. After Yu goads him by calling him weak, Shinya fires Byakkomaru, leaving Yu confused when nothing happens. Manifested tigers appear from Yu's left, and he strikes at them. This leaves him open, and Shinya puts his sword at Yu's neck.

Shinya informs Yu that Byakkomaru is a long-range weapon, so he would stand no chance against powerful melee-range fighters. He tells Yu that he has not learned about demon "manifestation" or "possession," so this was the most that could be expected of him. Although Shinya declines to give his name, Kureto provides it, saying that Shinya was originally from a junior branch family and was despised for it. He reveals that he's under investigation from the Army due to suspicions that he may be a spy. Yu's interview continues, and Kureto surprises Shinya by asking Yu about the Hyakuya Sect.

Nagoya Arc
Shinya drives to the Ebina Rest Stop to join up with the Moon Demon Company without invitation. He does this in a super-charged luxury sports car he happened to find along the way. Since it was too loud and attracted Horsemen, he had to stick sound-muffling illusion wards on it. When Guren asks him what he is doing there, Shinya asks Guren if he realizes this is a suicide mission. He says he decided to help him anyway.

Then, he and Goshi mock Guren for giving a short speech on a sports car. He is with Guren's squad at the rest stop when Yuichiro comes to receive his punishment. Once again, he and Goshi tease Guren about his calling them family. Each time, Goshi is the only one punished. They talk about their past a little. Yu says that if he and Shinya fought now, Yu is sure he would win. Shinya responds by calling him adorable.

Guren decides to test Shinoa and her squad with a match: her entire squad against Guren, Shinya, and Mito Jūjō. Shinya verifies that he and Mito just got thrown into a fight against three bearers of the Black Demon Series, which alarms Mito. Shinya starts off the match by firing Byakkomaru with manifestation coming at the kids from behind, effectively distracting Yoichi and Kimizuki and making them guard their rear. Then, Guren clashes with Yu, eventually sticking an explosion ward on Yu's forehead. As predictable as ever, Yu runs at Guren. Guren joking steps aside, where Shinya is waiting with his rifle and begins firing a barrage of bullets at Yu. Yu manages to block them, but Guren breaches the kids' lines and hands them their defeat.

In Nagoya, Guren leaves Shinya above ground to take over command if something happens to him. Shinya pairs up with Yoichi and works with the Shinoa and Narumi squads to kill Fifteenth Progenitor Lucal Wesker. Shinya coaches Yoichi on sniping, getting him to calm down and relax. He tells Yoichi the details of a sniper's job, including that they must kill any allies who fail to escape in the case of a retreat. When they fire at Lucal, Lucal grabs his aide Esther and throws him in front of their bullets. Esther dies, and Lucal attacks them from the ground, whacking the tower and making them cling onto it. Shinya and Yoichi eliminate all of the normal vampires on the ground they can while the infantry battles Lucal.



Shortly afterward, Shinya and Yoichi return to the ground and distract Lucal when he charges to attack Special Private Shiho Kimizuki. They successfully exterminate the vampire noble.

The Moon Demon Company regroups, and Sergeant Aiko Aihara arrives with only seven survivors from her squads. Guren Squad, Shinoa Squad, and Narumi Squad leave to hunt Thirteenth Progenitor Crowley Eusford, Seventeenth Progenitor Chess Belle, and Seventeenth Progenitor Horn Skuld while Aiko waits for other survivors to pass them the order to reconvene at Nagoya Airport. Shinya asks Guren if he is okay after losing so many soldiers, but Guren claims he will go home and cry later. Shinya goes with the team hunting down the three nobles.

Once at Nagoya City Hall, Shinya and Yoichi prepare to snipe Crowley Eusford. As soon as Yoichi fires Gekkouin at him, Crowley catches it's manifestation and flings it aside.

After careful planning, Guren decides that his squad will take his squad to attack Crowley while Shinoa and Narumi Squads free the hostages. He gives them five minutes to rescue as many hostages as they can and act as a proper diversion for the main force in Shinjuku. As soon as the five minutes are up everyone has orders to retreat to the Nagoya Airport immediately. Guren and Shinya attack Crowley at the same time but he easily negates their attacks at close range. He then swings Guren into Shinya, throwing them into the wall behind them. Crowley, Chess, and Horn then step toward them. Mito notices this and moves to assist them, but Goshi holds her back and tells her, she would only get in the way.

When Yu moves to rescue Guren, who is on the ground behind Crowley, Shinya stops him and orders him to abandon Guren. Shinya orders everyone to stop Yu but then notices enemy reinforcements. Shinoa says their five minutes are up and orders a retreat.

Outside, Yu breaks free of Kimizuki's grasp and complains about leaving Guren behind. Yu asks if ignoring feelings and abandoning family is acceptable as long as it is for their mission. Shinya tells him that they haven't abandoned him and remember what Guren told them: they aren't just coming home alive to protect their family, they'll come home victorious. Shinya then thank Goshi for creating the illusion that saved them.

After Shinoa squad recovers Yu from his fight with Crowley, Shinya is waiting for them outside. He orders at them to move as enemy reinforcements are coming. When they join up with Narumi Squad and many injured soldiers, he says that if the enemy reinforcements spot them, it's over so they have to leave the area immediately. They flee, and Rika Inoue reports seeing a single vampire straight ahead. Shinya says they can take on one noble and orders them to keep pushing forward. As Shinoa Squad tries to prevent Mika from taking Yu, Shinya uses the distraction to stab Mika through his back and chest. He tells Yoichi that he did excellent work and this battle is over. He tells Mika to die, alarming Mitsuba and Yoichi. Shinya uses the distraction to stab Mika through his back and chest. He tells Yoichi that he did excellent work and this battle is over. He tells Mika to die, alarming Mitsuba and Yoichi.

Shinoa activates Shikama Dōji and knocks Shinya away from Mika, surprising both of them. Shinoa Squad protects Mika and allows him to escape with Yu. When Shinoa watches them leave, the other humans knock her down, calling her a traitor and telling her to die. Shinya tries to interfere and orders them to not kill her. Makoto stops the sword of one of the men and asks him if he heard the major general's orders.

Shinya orders them all to move as common vampire soldiers jump down from the helicopters, surprising them in the midst of their drama. One cuts through Yayoi's left side above the hip, causing blood to spray all around her as she falls to the ground. Enraged, Taro curses him and charges in to attack. He stabs the vampire through the torso while the vampire stabs him through the chest simultaneously. Blood sprays out of Taro's mouth. Seeing his squad members die before him, Makoto curses them. Shinya orders him not to fight. He says they will be finished if any nobles arrive, so he orders a retreat as more vampires rain down around them.

After seemingly escaping the vampires, Shinya arrives with Guren Squad, sans Guren. Shinya says it is not up to Narumi who is disciplined as Narumi said to Rika that he would deal with Shinoa. Narumi asks him what he is going to do. He says they came this far on their orders, even after losing their commander, because they thought they were really doing something. He says he cannot see why they came here because no one is waiting for them and bloodsuckers will catch them soon. He asks if this decoy mission was meant to be a suicide mission from the start. Shinya does not answer. When prompted by Norito, Shinya says Guren told him a transport chopper was supposed to be waiting there for them to escape with. He says they were supposed to then use the chopper to fly to Shinjuku, where a trap is supposed to be lying in wait for the vampires.

Shinya reveals this plan was devised by Kureto, instantly alarming Guren Squad. Shigure and Sayuri, as Guren's aides, decide to abandon the mission to rescue Guren. Narumi asks for an explanation. He can accept a meaningful suicide mission as long as Guren gives the order, but he says the Moon Demon Company obeys Guren alone, not Shinya Hīragi. He says they are sick of the Hīragis, who sit safely above them and give out orders. Shinya tells him that is enough. Narumi asks Shinya how many of them think will follow orders from a higher ranked officer who orders them to march to their deaths. The company becomes disgruntled and asks what they should do.

Shinya wonders if Guren wants him to protect their lives or continue the mission. When Narumi demands an answer, Shinya tells him to shut up and says they will abandon the mission. Guren says their official orders are to hold position in Nagoya Airport, but he says they will instead plan to rescue Guren. The soldiers appear relieved.

A van pulls up, and Aoi Sangū steps out followed by Kureto. Shinya and the members of Guren's squad are immediately alarmed, surprising Makoto Narumi with their reaction. Yoichi and Kimizuki recognize Kureto as the one who tortured them while Shinoa and Mitsuba are concerned.

Kureto identifies himself and congratulates them on their successful mission. He says that, thanks to their glorious sacrifices, humanity will now achieve complete victory over vampire-kind. He says he will take over now and orders them to put down their weapons and be at ease. Shinoa orders them to hold onto their weapons and says she feels that something terrible will happen while Rika, Shūsaku, and Narumi hesitate. Shinya asks what exactly is going on.

Kureto ignores his question and asks where Guren is. When Shinya states Guren has been captured by the vampires, Kureto asks which personality let that happen. He asks if Guren really intends to fool him, which puzzles Shinya. Kureto mocks Shinya and asks if he has not figured it out yet. Kureto states that Guren's original and weaker personality is desperate to save everyone and liked them enough that he probably tried to put on a brave face. When Shinya asks for more information, Kureto orders him to be silent.

Kureto orders Aoi to kill the "sacrifices", and he disarms Shinya when Shinya demands that Kureto wait. Narumi approaches Kureto and asks what he is talking about. Kureto asks who he is and restates his order for the soldiers to drop their weapons. Narumi points out how many of them have died already and says it is his responsibility to keep his subordinates safe.

Kureto remarks on Narumi's passion and asks for his name. Shinya quickly shouts at Narumi to not tell him, but Kureto says Shinya cannot do anything to protect him anyway. Shinya pleads with Kureto to just let them leave. Kureto says that he is in a particularly good mood today, which makes Rika relieved. Immediately afterward, he says that everyone is going to die anyway and orders the experiment to begin. Aoi launches chains from the ground at the surviving members of the Moon Demon Company. They merely scratch Shinya and fire at the other soldiers.

An army of vampires arrive, cursing the insolent humans for their recent attack. The vampires and humans wage war. Shinya shoots vampires near Yoichi and says he and Guren Squad will back up the children. He orders them to run.

The experiment continues, and the demon Abaddon is successfully manifested. Yu then awakens in his seraph mode. He defeats the demon and later stabs himself through the chest with the cursed gear sword. After Yu falls, Shinoa tries to ask Guren what is going on, but she sees Shinya point his gun at Guren and realizes that their escape is up to her now.

Guren smiles and Shinya demands an answer. He tells Shinya to not be so angry and says he is fulfilling their dream of changing the army so that anyone can climb the ranks. Shinya asks him about betraying so many of his men before realizing Guren has been possessed, despite Guren not having the typical horns, dark eyes, fangs, or rampant curse marks associated with possession. He tries to call out to Guren, but Guren grabs Shinya by the neck as curse marks begin appearing on his face.

Post-Nagoya Arc
Three months later, Shinya is imprisoned within Shinjuku's Japanese Imperial Demon Army HQ. Aoi visits him. He addresses her as Kureto’s pet dog, and she immediately replies that she is Kureto’s pet. Although he pleads with her to open the cell, she refuses. She tells him that a Hīragi like him should act like one and quit begging. Aoi tells Shinya that Kureto will be returning to Shinjuku tomorrow. She gives him a message from Kureto, telling him to cease his “temper tantrum” and come to his senses in which Shinya tells Aoi to tell him to shut up.

Guren later visits him. Shinya immediately confronts him about killing his own soldiers. He draws Byakkomaru on Guren, but Guren does nothing to defend himself, which makes Shinya's emotions rage wilder. He wants Guren to admit he was possessed by the demon, but Guren insists he was in control. After that Shinya asks himself what he should do then he collapses onto the ground and breathes out that he won't be able to forgive Guren for what he did.

Osaka Arc
Shinya and the rest of Guren's squad meets Guren at Shinjuku complaining about their imprisonment; however Guren tells them to be quiet and that they must go to Osaka. He and the squad are next seen in a car being driven by Guren to their destination. Shinya demands for Guren to explain why he is taking them to Osaka and his actions at Nagoya, but is met with silence.

Later, Shinya chides Guren for suddenly swerving the car, but the squad soon arrives at the mansion without further incidents. He then sees Guren use his cursed gear's power and dodges the attack while the rest of the squad is knocked out. Byakkomaru then appears to Shinya to tell him that he can no longer trust Guren, and Shinya decides to fight Guren.

When Byakkomaru asks about him winning since he has the distance as his advantage, Shinya tells him to not expect things to go according to plan. While Shinya is able to keep a good distance away from Guren, he is unable to land any shots on him. Guren is able to close the distance to slash at Shinya, which the latter is able to dodge with an illusion spell. Shinya behind Guren to slap a fuda on him, only for Guren to slap an exploding fuda on him and activate it. The two end then decide to trade blows with each other in which Shinya loses. Weakened and lying on the ground, Shinya gets scolded by Guren for fighting close range, but he admits that he allowed the former to punch him as payback for the secrets he’s been keeping. Shinya decides to Guren to keep his secrets by allowing the latter to knock him out.

He and the squad are then taken into the bedrooms of the mansion by Guren where they remained unconscious until they are woken up by a transformed seraph Yu. Later on, he and the other two squads listen to Guren's strategy to rescue Krul and Ferid from Ky Luc, and Shinya's part was to shoot at Ky Luc with Byakkomaru.

Shibuya Arc
Shinya listens as Yu explains to Kureto what he knows of the monster. He looks to Guren when Yu is taken away declared as an experimental subject (with Yu's willingness as he wants to save Shinoa). It is all new information for Shinya when he learns from Guren of the link between the monster, Mahiru and Saitō. He thought he and Guren were friends and asks if this is the case wondering why he was not informed of this. Asking what is with them two, Shinya cannot make sense of why Guren is unable to divulge what he knows, but when Kureto suspects a curse it clicks for Shinya. Asking how long he has been stuck with it he tries to encourage Guren to open up by thinking whatever happened must have occurred eight years ago on the night of the apocalypse. Shinya feels ever since that night he has noticed that Guren has held himself aloof and been maintaining a distance even between his friends. Being cut off, Shinya is told not to pry, being unaware that if the dead learn that they have been brought back to life, they will return to dust. Shinya continues to listen to Guren and Kureto's conversation unaware that he is being embraced by Mahiru-no-Yo from behind.

He remains close to Mito as they listen to Guren question Mika's implied plans. When Mika attacks thinking they are puppets of the first out to use Yu, Shinya has his gun ready. Being told to end it by Guren, he complies apologizing beforehand that this is going to hurt a lot before firing, only to be stunned that Mika was fast enough to evade the shot. With Kureto ending the dispute and Mika grounded and unarmed, Shinya hears Guren chide him that no one can do anything on their own. Shinya is asked by Guren on how they can stop the first and teases Kureto on his response that they have to stop it anyway they can, also asking how long he spent practising his cool one-liner. Their plans are interrupted by Ferid, who is revealed to be in the clutch of Shinoa. He is unnerved at her presence as she arms herself with many floating scythes.

With the first attacking, Shinya appears shocked to hear an emergency message that a group calling themselves the Hyakuya Sect are outside Shibuya city's walls. The first crashes though a window leaving them and Shinya asks Guren what now. He tells him to come after Kureto states their counter measures.

There is heavy missile fire upon Shibuya from helicopters where explosions occur near Shinya. He jokes to Kureto that he missed some of them when Kureto used his cursed gear to try and clear the air of them. Shinya then open fires successfully destroying multiple targets but there are just too many of them and Shinya wonders what they are after with all this.

Managing to avoid an ambush from behind, Shinya notes his attacker is fast and is shocked to find a vampire. Reaching a wall he can see it is a noble at that and calls to Kureto that there is vampire nobility. Ducking to avoid a sword swipe Shinya is cornered as the vampire raises their sword.

Remaining on his position on the ground as Basteya Irclu interacts with Crowley and Ferid, Shinya is joined by Sayuri, Mito, Goshi and Shigure. A voice orders Jigenso to slice it open and a Hyakuya Sect agent joins Basteya atop the wall through a portal. Stunned recognizing the weapon as cursed gear, Shinya instantly fires Byakkomaru at the newly arrived foe but identifies Jigenso as a black demon level when his attack is deflected by it.

Shooting again at the agent, Byakkomaru is redirected through a portal into Shinya's ally, Crowley. To gain some space he jumps straight off the wall and free falling he does his best to fight physically using his rifle, hearing the agent is not going to let him have the distance he needs. Drawing upon a spell tag, his one connects with his attackers and although Shinya avoids the blast he is beset by another spell tag appearing behind him from Jingeso's rift.

After Ferid deals with Shinya's pursuer he manages to land safely and remarks that Ferid certainly managed to beat the agent easily enough. After a hint to do so Shinya thanks Ferid then points out that he told him to do so after Ferid insists there is in fact no need to thank him. He listens as Ferid has a plan requiring Shinya's sniping specialism.

With the Hyakuya soldiers pacified via chains Shinya can already tell this is bad and asks where is Guren. He suggests to the squad they should go and find him, not appearing too pleased when Ferid agrees that he thinks that seems fun.

He notices and shouts for everyone to get down, leaping to the floor himself to narrowly avoid a large scythe that has rebounded off from the fight between the first and Saitō. With the heavy damage to the city, after a moment Shinya feels that Shibuya is probably a lost cause and they should retreat and regroup whilst enemies are not attacking them. He plans for the group to head back to the barracks and find Guren first.

Visualized by Guren, it is noted that Shinya will die a second time at some point, and to bring him back to begin with involved the sacrifice of just about every human in the world.

Arriving at Guren's location, he appears shocked to see chains coming out of Guren's back and runs towards him. When the chains rise in the way, Shinya shoots them apart and through them he see's Guren, and Mahiru as well. Gathering himself after this surprise, Shinya raises his gun to her and asks what she is doing to Guren. Hearing that is a secret, Shinya orders her to get away from him and if she does not, he will kill her. Told he will have the power to do that, he calls upon Byakkomaru for it. With electricity surging around his rifle, Shinya finds chains directed at him. and calling to Guren, Shinya fires.

Seeing waves of energy emitted from Guren, Shinya asks what it is. Turning to the others, he states they need to restrain him. Subjected to a crushing like effect, Shinya struggles to not be flattened as he calls for the others to hang in there, he will dispel it. He manages to remain standing even as the power cracks the ground around him. Resisting the compression with no intention of letting Guren win that easily, Shinya's eyes darken as he requests Byakkomaru to give him more power to save Guren.

His imploring is refused, and Shinya comes face to face with a human appearing form of Byakkomaru in a misty landscape. Shinya states he has to save him, asking for more power, he says it does not matter that it will do no good with the demon they are facing. Tapped by Byakkomaru, Shinya is young and standing in the rain with deceased children all around him. He listens as he is told that feeling nothing is what allowed him to survive for this long. Even when he never managed to make Mahiru his, he felt the same and Shinya speaks to say there is no need to, it is the way the world works. Making an effort to acquire a thing, to still lose it, if that is the case then the effort is meaningless.

Hearing Byakkomaru agree then state that Guren is beyond saving and he should run, Shinya replies no, that he is going to save him. He laughs off Byakkomaru's question on what makes him so obsessed with Guren, stating that as his demon he knows the answer. Smiling when Byakkomaru says that it is because Guren has what he does not, Shinya pays no mind to Byakkomaru's assessment on Guren's dire circumstances. He appears happy that Guren has not given up on a single thing. Remembering Guren from a different time, Shinya voices that no matter how many times he fails, despite knowing that whatever he tries is never going to work, he never gives up. It is like he is an idiot, and Shinya confirms with Byakkomaru that he hates idiots, Guren included, and perhaps might abandon him.

Continuing that reply, Shinya makes it clear that he is saying he will, but will not. With Byakkomaru commenting that it is as if he is in love with Guren, Shinya puts it down to garden variety idolization. He completely understands why Mahiru chose Guren over him, he lets himself get hurt over again like a moron, but never gives up regardless. Asking Byakkomaru if that does not make him want to help, Shinya does not seem fussed that trying to save him will probably get him killed, in fact considering it very likely. Saying it is a good question on whether he intends to die here, Shinya does not care either way. To live or die, in this world, what is the difference. He has never really had something so great as a reason to live. If he were told right now that he had to die, his small regret that would annoy him is that he would have given up before Guren.

Extending his hand, he invites Byakkomaru to devour his desires. Not caring if he turns into a demon, Shinya wants all the power he can give. He names his desire that he will never give up on Guren and in an explosion of power, Shinya is transformed into a two horned demon. Calling to Guren, he is not letting him go off and leaving him on his own. His gun fire is deflected, and the attempt to get Guren to look at him results in Shinya being swept away for him to crash into a wall.

His communication turns to Mahiru, that he will not let Guren leave like she did. Shinya insists that Guren is staying here with them and fighting together with the squad. Shinya says he can stop Guren, because he wants him to stay, he is not Mahiru after all. As he attempts to reason that Guren will always be himself, it is what they promised, he is sure that Guren can still stop. Then he hears that this being is not Guren anymore, and stabbed through the chest by Guren. Falling to his knees, Shinya weakly asks if this is not Guren then who is he and is unsure of the response.

Addressing Mahiru, he begins to ask about Guren before being stabbed by one of the chains and having his power sapped. Clutching his stomach, he asks Guren where he is going all by himself. Laying on the floor, the chains begin to fizzle away rising he comments on that idiot who thinks he can save the world by himself again. Asking if everybody can move, he states they are to go after Guren.

Post-Shibuya Arc
It is recollected that Shinya was held by Guren when he explains his role in causing the catastrophe. Shinya lies still as he is carried by the second progenitor Urd Geales, and brought alongside Kureto to where Saitō's prison is. Lying on his front, he is turned over by third progenitor Lest Karr and remains unconscious as he is struck by a chain from a pentagram that Saito has made. Shinya's body is again affected by a chain, this time where one directed into him can be used by Saito to communicate with Guren some distance away through Kimizuki.

After Yu has returned with Mika who is now a demon, Shinya is remembered appearing deceased by Guren eight years ago before the moments before the catastrophe. When Guren and Yu are fighting, Shinya is mentioned by Mahiru when she is explaining to Guren that they both admire what he sees as weakness. After Yu tells Guren he is not alone and to take their hands, Shinya is visualized smiling. He is seen beside Goshi, with Shigure, then Sayuri and Mito as well.

Natural abilities
Shinya, like all users of Cursed Gears, has heightened physical abilities. He is shown to be able to take command of the Moon Demon Company after escaping from Crowley, and is an adept fighter. Byakkomaru has once said that he has confidence in Shinya's skills, believing that he'll be able to defeat Guren in a fight. Guren himself acknowledges Shinya's strength, knowing that he has no chance against the latter if Shinya snipes at him.

Being raised as a Hīragi, Shinya is one of the best fighters in his school, as the fluidity and grace in his movements is noted by Guren as superior to most of their classmates.


 * Marksmanship: Shinya has superb marksmanship. He's able to shoot down targets from long distances with deadly accuracy, as shown when Ferid barely got away from his shot, and even got an arm injured. Shinya is apparently skilled enough in the art of shooting to help coach Yoichi in their mission of killing Lucal Wesker.
 * Talisman: Shinya is an expert in using talismans, often cloaking his presence with them, or sealing up the movements of his enemies with them. As noted by Guren, Shinya's incantation speed is extremely fast, and the former immediately marked out the latter as a dangerous individual. Prior getting his Cursed Gear, Shinya fights almost exclusively with talismans, and is able to keep a demon-possessed Guren at bay with them.
 * Swordsmanship: Shinya is shown to be able to wield his first Cursed Gear, which takes the form of a sword. He's able to slice off a vampire's arm with it.
 * Hand-to-hand combat: Even though his specialization is long range and when he engages in close combat, he mainly uses a weapon, Shinya displays he can actually fight considerably skillfully in hand-to-hand and is confident enough to charge at Guren unarmed when he was angered, able to bruise him and hold his own for a time, although he was still fairly quickly beaten, with Guren even admonishing him for his reckless charge.
 * Anime exclusive: Shinya is shown to be able to cover up Byakkomaru's weakness of close distance fighting, by using his rifle to block melee attacks and sweep under his opponent's feet to unbalance them. His skills are great enough that when he fought against Yūichirō, he easily disarms the boy and ends their fight in mere seconds.

Cursed Gear

 * Unknown Cursed Gear: Prior to getting Byakkomaru, Shinya uses a Cursed Gear in the form of a sword. The rank of the sword is unknown, but like all Cursed Gears, it gives Shinya greater physical strength and healing abilities.

Shinya can fire bullets which can split and then manifest into several white tigers. Each tiger can move independently, as if they have a will of their own. Applying the demon to the bullets increases its power and range. Shinya can additionally fire at something and make the tigers come from behind whatever he shot at, but he can only do this once within an unspecified amount of time as a surprise attack.
 * Byakkomaru (白虎丸): A manifestation-type demon weapon from the Black Demon series wielded by Shinya Hīragi. It takes on the form of a black rifle with a glowing green streak down the middle. Byakkomaru's specialty is long-range firing and it is not very effective in close-range combat. While so, the tigers are fired and created in flames from out of the rifle.

Book 1
"Fine, fine. But it seems a shame. I was looking forward to meeting you. I was hoping the two of us could be friends. I hate the Hiragis just as much as you do, Guren. I figured the two of us might be able to stir up some trouble together."

- Shinya to Guren.

"Haha! You should see the look on your face. If you don’t want people to suspect you, you’re gonna have to try a little harder to hide that ambition. But see? You and me are on the same side. And don’t worry about Mahiru. The truth is we aren’t that close. Even with the Hīragi name, I’m still just one of their adopted urchins. They treat me like I’m something they stepped in. Basically, the way you get treated at this school is how I get treated at home. It really pisses me off. But someday I’ll bring the whole clan falling down on their heads."

- Shinya to Guren.

"Here we go. Time to hear our goddess give her speech."

- Shinya to Guren.

"In my experience, people who can deprecate themselves like that are the most dangerous."

- Shinya to Guren.

"In that case, stay away from Mahiru while you’re at it. You don’t have the right to talk to her. You don’t have any power or self-respect. Someone who can’t even put in the effort shouldn’t have come to this school in the first place. You’re not fit to walk the same halls as Mahiru."

- Shinya to Guren.

"Enough. I’ve heard your excuses. Long story short, you were born a loser and you’ll die a loser. Right? I guess I was right about you, then. If you had at least shown some spine, I would have told you Seishiro’s weaknesses instead. But I guess there’s no point. Forfeit the match. If you try fighting with that attitude you’ll just be killed. That’s the kind of person Seishiro is. He’ll humiliate you, and then he’ll kill you. The teachers won’t stop him either. They wouldn’t even lower his evaluation for killing you."

- Shinya to Guren.

Book 2
"Together, the Thousands Nights and the Imperial Demons are the two most powerful magical syndicates in Japan. Now they’re at war. If things go off course, the whole country could be destroyed."

- Shinya.

"Whoa, whoa, whoa. Hold on. You’re not planning to use bloodbane magic, are you? In your current state… You’re gonna get yourself killed. That spell was created to kill vampires, right? But no one’s actually ever tried using it. After all, vampires are so much faster and stronger than humans that it’s hard to imagine anyone getting nine hits off on them in the first place. The same applies here, Guren. How are you gonna get nine hits off on that creature? It’s time to retreat. If we stay here, we’ll all be killed."

- Shinya to Guren.

"Let’s work together. We have to stop her from leaving. If we let her go now, she’ll destroy herself. You can see that, can’t you?"

- Shinya to Guren about Mahiru.

"You could never be like Mahiru, Guren… But I don’t think that’s a weakness. After all, if you were willing to make the same choice that she made, we wouldn’t be trying to save her in the first place. Would we now? You know I’m right, don’t you, Guren?"

- Shinya to Guren.

Book 3
"So I survived… I get to live."

- Young Shinya.

"Mahiru means 'midday,' doesn’t it? You shine like the midday sun, my lady. Shinya seems like the perfect name for someone like me, lucky enough to breathe in your shadow."

- Shinya to Mahiru.

"Now I get it. When they told me you were coming I wondered what you would be like. I never expected that someone from the Hīragi Clan would be a run-of-the-mill, lovestruck little girl."

- Shinya to Mahiru.

"After all, I’ve never lost at anything before in my life."

- Shinya to Mahiru.

"Alright then, I’ve decided. I don’t mind being your cover for now, but someday I’ll make you love me. That’s my next challenge."

- Shinya to Mahiru.

"I guess… I just lost, didn’t I?"

- Shinya to Mahiru.

"--Oi! Who said you could look at other people’s phones, Guren? You creep! LOL"

- An email Shinya leaves open on his phone for Guren to find.

"You're gonna have trouble keeping your friends if all your tactics involve lying to them. You were actually planning on going and meeting with the Thousand Nights on your own, weren't you?"

- Shinya to Guren.

"I don’t know… I always knew Mahiru was in love with you. Still… I guess I am. I just don’t like losing to you. Why do you suppose that is?"

- Shinya to Guren after Guren confesses he slept with Mahiru.

Book 4
"I’m just adopted. And after what happened with my bride-to-be, I’m guessing I don’t hold much value for the clan anymore."

- Shinya to Kureto.

"On the other hand, with so much darkness in the world… …he’s precisely the kind of person we need. Someone worth saving."

- About Guren.

"Come on Guren, cut it out… Snap out of it. You became a demon just to save your friends. If anyone can do it, I know it’s you…"

- Shinya to himself.

"No way, Guren. You’re not going to sleep with my fiancée and get off the hook so easy. I’m gonna save you whether you like it or not. I’ll make sure no one else kills you, either. If I messed this up, too, my whole life would be just one big failure."

- Shinya to Guren.

"I know, just kidding. I understand that it’s hard for you to trust me. You’re worried this could be a ruse. But we don’t have time for that right now. Things have taken a pretty big turn for the worst here. Me and your son were fighting over the same girl, and we were carrying out a bunch of research to try and save her… But we slipped up. We both pretended to be unpopular loners, but in the end we were the ones who were getting played. You know, pops, you probably should have taught your son how to deal with girls a little better."

- Shinya to Sakae Ichinose.

"Have fun while you can, demon. We humans are going to find a way to make you obey. And once we do, your kind will be our slaves for all eternity."

- Shinya to Guren/Noya.

"Me, I knew what I was doing when I saved you… You say there’s no such thing as friends? Get real. We are friends. And it’s your fault. You’re the one who brought trust and friendship into the crazy world we live in. You’ve got a kind of madness that Kureto and Mahiru can’t even begin to dream of. So now… Take responsibility for what you did. You have to lead us—lead this team—properly. There’s not a whole lot of things to believe in in this world. But we’re ready to follow you."

- Shinya to Guren.

Book 5
"Look at my face. Look at how serious I am. Does this look like the kind of face that would lie to you?"

- Shinya to Guren after intentionally knocking into Guren repeatedly with his shoulders and elbows while they play video games into the wee hours of the morning.

"We’re a team… We’ll get Mahiru this time, before these two days are up. We’re here to help."

- Shinya to Guren.

"Ahaha, fuck off with that. If you think fiancés matter so much, then you shouldn’t have slept with mine."

- Shinya to Guren.

Book 6
"Yeah, but I don’t think friendship’s so bad… Without it, what’s the point of living? If you’re not close to anyone, then why be alive? …I was always forced to fight growing up and told the only thing that mattered was to become strong enough to deserve the Hīragi name. Might was right. But no matter how strong I get, it’s not like I can break free of my human limitations and become some sort of god… What then? I can’t become a god, so maybe I should try to become the head of the Hīragi Clan instead? But that path wasn’t open to me, either. I’m just some filthy foster child. Besides, I wasn’t really that interested in leading the clan in the first place… So what did I have to live for? I’d already lost my only goal. No matter how strong I became, I couldn’t find an answer to that question. If not strength, what should I live for?"

- Shinya to Guren.

"But if we’re not close to anybody, I don’t think there’s much point to living. You feel the same way, too, don’t you, Guren? That getting strong just for the sake of it is meaningless? …I think the meaning lies in protecting and supporting others… right? You can’t just think about yourself, can you?"

- Shinya to Guren.

Seraph of the End: Vampire Reign
"Byakkomaru, fire. 'Bang. ' ""

- Shinya when he fires his weapon.

"I don't like picking on powerless kids like you do."

- Shinya to Kureto.

"Aha ha... I feel the same way. Sheesh... This place is truly... rotten."

- Shinya to himself about the JIDA.

"You're still going to die. But you're going to go anyway, because you're stupid like that. So I decided to be nice and come help you. Again. Now where's your thank you?"

- Shinya to Guren at the Ebina Rest Stop.

"This is your first sniping mission, correct? Guren asked me to walk you through it. So I'll teach you, okay? First, calm down. Take a few deep breaths. Calm your body. Slowly... take control of the space. As snipers, our job is to stay calmer than anyone and kill the enemy. We back up our allies on the ground... and if things go south and we must retreat... we must kill any of our allies who fail to escape, before they can be captured and tortured."

- Shinya to Yoichi on sniping.

"I just want to know if you're okay. A lot of good people died today. You've never been good at handling that kind of loss."

- Shinya to Guren.

"Dammit...! What do you want me to do, Guren? What did you entrust me with when you left them to me? Was it the mission... or their lives? If it's their lives, then did you want us to abandon the mission?"

- Shinya's thoughts.

"You can shut up now! I get it, okay?! You want to abandon the mission? Fine! We abandon the mission. Geez!! Our official orders were to hold position here... But we will ignore that! Instead, we are going to regroup and devise a strategy to rescue Guren Ichinose!"

- Shinya to Narumi Makoto and the Moon Demon Company.

"Kureto... Brother. We just got done fighting on the front lines. We lost a lot of good people. I'm not in the mood to go along with any of your jokes. If our mission was a success... then let us leave."

- Shinya to Kureto Hīragi before Kureto orders the deaths of the surviving Moon Demon Company soldiers.

"What the heck are you saying? Your own men are dying, Guren. Do you have any idea how many of your own your betrayal killed...? No... Not you... Your demon!! HEY, GUREN!! CAN YOU HEAR ME?!"

- Shinya realizing Guren is possessed.

"But in all honesty, your conscience is bugging you... right? You've killed dozens--if not hundreds--of your own comrades in human experiments. The Hīragi family claims it is all for the greater good, but, in the end, all they know is how to trample others for their own personal gain."

- Shinya to Aoi.

"Damn you! Why won't you draw your weapon?! Why don't you dodge?! Dammit!! Tell me why!! Please!! You aren't the kind of man who would do that!! Your demon. That's it. You've been possessed by your demon. Right?"

- Shinya to Guren.

"Shut up, shut up, shut up!! That can't be right!! If it is... If you really aren't possessed by your demon or by Mahiru, then-- Then what am I supposed to do? I... I won't be able to forgive you. If you aren't possessed...then why the hell did you do what you did? What are you after?"

- Shinya to Guren.

"Aha ha! Don't think you can keep a secret to yourself around us. Even if you don't say a word, we'll figure it all out."

- Shinya to Guren.

"I just realized it was a dumb question, that's all. You always fight for your family. That's just the kind of person you are."

- Shinya to Guren.

"Are you telling me that you've been hiding a secret desire to laugh at things no one thinks are funny? That's so... so... so just like I always thought you were."

- Shinya to Kureto.

"Ooh, what a cool one-liner! How long have you been practicing that one, big brother Kureto."

- Shinya is pleased at Kureto’s declaration that they decide their own fates, and to fight the first.
