Shinya Hīragi

Shinya Hīragi 「柊 深夜, Hīragi Shin'ya」 is a supporting character of Owari no Seraph. He is a Major General of the Japanese Imperial Demon Army. He was chosen to marry Shinoa’s older sister Mahiru 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's. However, he is good friends with Guren who also holds the same intention against them.

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

He wears the standard JIDA uniform which consists of a long-sleeved black jacket with red details including the shoulder epaulettes, an aiguillette worn on the right shoulder with a crescent moon decoration, and two rows of gold buttons on the front. Along with that, he wears a pair of white gloves, an armband on his left arm, and a white web belt with a gold waist-plate. He also wears the uniform trousers with black shoes.

Personality
Shinya is shown to be a very calm and somewhat gentle person, even when insulted or made fun of, especially compared to other members of the Hīragi family. He warns Yū not to take what Kureto says at face value and dislikes picking on the weak.

He has been friends with Guren since their school days, and seems to enjoy picking on him, often by forcing Guren into awkward situations or simply annoying him.

History
Shinya was adopted by the Hīragi Family from one of their junior branch families. At a young age, he had been selected, alongside several talented children, to be the potential mate for Mahiru. This was a plan by the Hīragi to keep their bloodline strong. His childhood days were filled with training and fighting. Failure to distinguish himself among others meant death. Finally, he was singled out from the other candidates and was adopted into the family and engaged to Mahiru, with the rest of the candidates killed.

It was uncertain whether he bore any true affection towards Mahiru, though he was somewhat jealous of Guren. Despite that, he was depicted to be a true friend towards Guren. He initially initiated a collaborative effort with Guren to crush the Hīragis with him acting as a double agent. Due to the series of events with greater things at stake, that did not come to pass. Over time, he grew to respect and admire Guren and accepted the Kiju (Demon-Curse) from Kureto to save Guren.

Past (Volume 3's prologue)
Shinya was five when he was adopted into the Hīragi family. His parents received 300 million yen for this and he was chosen to be a part of a select team of children gifted with talent. Since then, all he did was compete with other children in the same situation as him: killing each other was allowed, and he'd die if he didn't win.

All that five-years struggle was in order to meet his fiancée, Mahiru Hīragi. This whole purpose was actually to gather the most talented children as fiancé candidates and therefore, provide another child with excellent and superior DNA to the Hīragi family, so they could keep their bloodline's perfection.

At age ten, the competition was over and he was the only one child left, the winner. After those 5 years of killings, he has reached his goal and was then able to meet his fiancée for the first time. When he faced Mahiru, she told him that she didn't love him and will never fall in love with him, which made Shinya wonder why he had to go through all this competition since he only survived for that reason. He has never lost before and it was the first time he did. Mahiru told him that she loved someone else and that there was definitely no chance for her to fall in love with Shinya. He assumed that this person she loved wasn't accepted by her family.

Shinya then thought he was going to get killed since this whole purpose had no meaning anymore, but Mahiru told him that there was no need to worry since she was going to pretend she liked him. Shinya then said he'll act as a cover-up until Mahiru can be with the person she loves.

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
He arrives with Kureto and the Shibuya Main Army as reinforcements in the battle at Shinjuku in chapter 14. 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 at the end of chapter 16 for Yūichirō's "interview."

In the next chapter, 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
In chapter 24, 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 Gekkōin 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 thanks Goshi 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. 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 Goshi, 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 Yukimi and Sayuri Hanayori, Guren's aides, decide to abandon the mission and 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 Hiragi. He says they are sick of the Hīragi's, 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. Although she notices Mitsuba, she quickly turns from her. Then, Kureto steps out. 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. 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. 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.
