Guren Ichinose

Guren Ichinose 「一瀬グレン, Ichinose Guren」 is the main protagonist of the Owari no Seraph: Ichinose Guren, Jyuurokusai no Catastrophe series and an important character in the Owari no Seraph series. He is a Lieutenant Colonel of the Japanese Imperial Demon Army and the commanding officer of the Moon Demon Company.

Appearance
Guren is a tall, young man with medium length black hair and purple eyes.

He wears the standard JIDA uniform which consists of a black jacket with red details including the shoulder epaulettes with an aiguillette. He also 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 white belts around his left leg and black shoes.

Personality
Guren was naive in his childhood days and spent most of his time with Mahiru. His aspects on life felt simple as he was in his happy moments. But after he was treated with disgust due to his name as a lowly born branch member, he began to feel guilt. He though that because of his weak physique and power, he couldn't reach out for what he wanted, which was hinted to be Mahiru. She motivated him to become stronger and wiser.

He is a wise leader who values teamwork and cooperation, determined to preserve the survival of the human race from demons and vampires. When Yu wanted to join the Moon Demon Company, Guren refuses to allow him until he made friends.

He pretends to be lazy, but he actually works hard and keeps many secrets, which he has no difficulty lying about. He plans to dethrone the Hīragi Family.

He cares about his subordinates and friends, considering them to be family.

History
Guren was born into the Ichinose family, a low branch family of the Hīragi. He was also the best friend and lover of Mahiru Hīragi, but this was frowned upon because of his low birth. Since they were friends, Guren was treated badly and blamed for, also getting beaten by the adults.

He appeared at the end of chapter 1, using information from a prophecy to collect Yūichirō Hyakuya, a survivor of the Hyakuya orphanage.

Story: Light Novel
???

Prologue
Guren arrived outside the entrance of Sanguinem during the daytime at the end of chapter 1 (at nighttime in the anime adaptation). He says that one of the lab rats from the Hyakuya laboratories, the company responsible for destroying Japan, is there just like the prophecy said. He tells Yu that he will be useful in exterminating vampires. Exactly what prophecy he refers to has yet to be mentioned again in the series.

Second Shibuya High School Arc
Over the next four years, Guren trains Yū to become a soldier of the Japanese Imperial Army. He teaches him how to survive above ground, how to live in the Demon Army's cities, and how to use a sword. Unfortunately, he is less successful at teaching Yū obedience and subordination, which is shown in 2020 in Shibuya, Tokyo at the beginning of chapter 2. Once Yū is sentenced to high school for his disobedience, Guren assigns Shinoa Hīragi to act as Yū's surveillance officer. When Yū refuses to follow orders to make friends, Shinoa gives him a note with the written orders. This note is the first time anyone in the series addresses Yu as a "virgin." Although Shinoa mocks him for being a virgin most often, Guren may have given her the idea to do so in the first place.

During those four years, he also worked on human experimentation for the development of Black Demon Series bearers.

Shinoa finds Guren during chapter 2, alerting him that a vampire escaped onto the school grounds. Guren kills the vampire attacking Yū, giving her an unpleasant surprise when she realizes he used a cursed blade.

Although Guren then rejects Yū's request to join the Moon Demon Company to exterminate vampires, Yoichi appears, tackling Yu and appearing as his friend. Guren makes good on his promise, finally accepting Yu to the Moon Demon Company along with Yoichi.

Shinoa informs Guren when Yū manages to overcome a myo-o demon's thrall on his own. After that, Yū and Yoichi attend their first class class in the Moon Demon Company barracks. After he introduces them, Yu picks a fight with Guren, and Guren assigns Yū the seat in front of Kimizuki. Naturally, the two boys start another fight, and Guren finishes it.

Later on, Kimizuki arrives in Guren's office and asks him if he can receive a demon weapon since he is stronger than Yu, but Guren turns him down, warning him that he will be devoured by the demon if he has no bonds to pull him free from the demon's clutches. At the end of chapter 4, Shinoa recommends both Yu and Kimizuki to Guren as candidates for the Black Demon Series weaponry. He plans to rebel against the main family.

In the following chapter, we see him rebelling by sleeping and snoring during a meeting with the higher-ups. He manages to escape a "stupid" political meeting by appearing rude. Yu attacks him, and he decides to proceed with Yu's training so that the upper brass do not notice him. He kicks Yū in the head before continuing with his day.

In chapter 6, Guren appears in the classroom. Sayuri informs him that Yoichi may be stable enough to resist demonic temptation. Guren attacks the classroom, filling with a demonic aura that sends most of the class tumbling to the floor, many of whom go unconscious. Sayuri struggles to stand by using two spell tags. Yū and Kimizuki tremble. Shinoa manages to remain standing just fine, and Yoichi is completely unaffected by the attack to the point where he does not even feel it. They are the only ones standing. Since he experimented on the three boys previously for this purpose, he is not surprised when they stay standing. Contrary to his expectations, Shinoa remains standing as well, proving herself as a possible candidate for Black Demon Series Cursed Gear as well.

Before he takes the three boys to make contracts with demons, Sayuri informs Guren that Yoichi may not be strong enough to accept the demon, although his heart is very stable. Guren takes him anyway.

Yoichi becomes possessed, and Guren orders Yū and Kimizuki to kill him. In the end, they manage to help Yoichi regain control and turn back to normal from being a man-eating demon, and it is actually Guren's words that make him snap out of it. Shinoa wonders if Guren planned this ending from the start.

Shinjuku Arc
When Guren assigns Mitsuba Sangū as the fifth member of Shinoa's squad, she protests against being assigned to a squad of rookies, especially working under Shinoa. Eventually, she submits.

Guren and his team enter the field early on in the battle at Shinjuku. He scouts for the enemy commander, spying Mika and Ferid. Ferid spies him back, which Guren finds mildly concerning. Then, he charges in at the 5th Street intersection, killing several vampires with a single strike. He leads the battle, facing off against Mika.

Guren fights head-to-head against Mikaela Hyakuya, complementing him on his strength. Mika disses him in return. Although he manages to trick Mika and nearly deals him a dangerous blow, Seventh Progenitor Ferid Bathory defends Mika, backhanding Guren and sending him flying. Mika lets Guren chat briefly with his squad but does not allow Guren to take a second dose of the supplement, which has a high risk of sending him into shock and potentially killing him but may increase his power. He notes that Mika is faster than before, and Mika disarms him, stabbing him through the chest and nearly killing him before Yu intervenes.

When he attempts to kill Mika with Yū's help, Yū freezes, and Mika escapes. Although Yū desperately wants to reclaim Mika, Guren issues orders to retreat. Ferid plays with Guren, eventually grabbing him by the neck. Ferid swindles his opportunity to kill Guren, and he asks him about Yū, even though Ferid already knows the answers. Guren calls Yū's transformation his "ace in the hole" after subduing the it by commanding Shinoa to embrace Yū. Guren makes a comment about being a decoy, and Ferid notices Shinya, barely escaping a sniping attack. The main forces arrive, chasing away the vampires. He rejects Shinoa's request for answers, and she spends five days hunting him down before finding him in a lab underground.

Post-Shinjuku Arc
Yu went berserk because Guren had Shinoa give him a special supplement. Although she asks Guren about it, he gives her no straightforward answers, and he only tells her that the medicine should wear off in five days and Yu should wake up soon.

In chapter 16, Guren waits for Yū while Yū heads to meet with the higher ups. Guren reminds him that Yū owes him and belongs to him, which irritates Yū until he realizes Guren does not get along with the upper brass. Their conversation becomes lighter when Guren tells Yū he can even call him "papa."

While Yū attends his meeting, Guren meets with the demon Mahiru within his mind. When Yū exits with an injured Yoichi and Kimizuki, he yells at Guren to teach him the proper way to use his Cursed Gear.

Guren meets with Shinoa and Yū before the actual squad meeting. They introduce Yu to the two types of demons, and Guren throws Yu from the roof. He has a heart-to-heart with Shinoa about her sister and tells her that he would let Shinoa kill him. The rest of the squad arrives half an hour early, interrupting their meeting. Guren claims Mahiru is not in control of him, and he orders Mitsuba and Shinoa to advance the training of the three new recruits before heading elsewhere for a nap. He admits to using Yu for experimentation from the very start, and he agrees to reclaim Mika as well.

Nagoya Arc
In chapter 23, Guren meets with Kureto Hīragi. He walks up toward where Kureto oversees five chained and starving vampires. Kureto claims he is testing to see if he can force vampires into becoming demons, so they can create Cursed Gear more efficiently. He claims that most of the low-level vampires do not turn, and those that do turn become weapons even weaker than the replicas of the stronger weapons. Kureto orders them killed and steps down to speak with Guren. They bicker a little, and Kureto asks Guren how he created so many Cursed Gear users (Yū, Yoichi, and Kimizuki). Guren starts saying that he just got lucky, but Kureto says that every single human capable of bearing a Black Demon has been a human experiment at one point. Even with the experimentation, the chance a candidate is successful is slim. The fact that Guren managed to create three of them, all successful, is extremely impressive. Instead of pressing the issue, Kureto tells him that success is a boon and asks that he share his experiments with them if more are successful. Kureto then asks Guren if he is planning a coup. They reminisce briefly on their high school days. Kureto calls Guren out on what he sees as Guren's weak point: no matter what happens, he claims that Guren cannot betray his friends. He says this weakness is why Guren is unworthy of being a leader and also why he trusts Guren. Guren asks him what hostage Kureto prepared this time, but Kureto says he was too busy. Kureto asks Guren about his vision. Kureto announces his dream of eradicating all vampires in Japan, then crushing all other surviving human organizations, and finally uniting the world under the Japanese Imperial Demon Army.

Kureto then gives him orders to lead a pre-emptive strike with 100 soldiers on the vampires in Nagoya. Guren calls it out on being a suicide mission, but Kureto claims it is a vital mission instead.

Proceeding with the mission, Guren waits for his troops to arrive at the Ebina rest stop prior to leading the strike on Nagoya. While his squad messes around, Shinya arrives unannounced to give Guren a hand. He also believes this is a suicide mission. He gives a brief speech to his squad, causing Sayuri, Shigure, and Mito to blush. When Goshi and Shinya tease him for giving the speech on a sports car, he manages to hit Goshi and orders Sayuri and Shigure to get him a different stage. When Shinoa's squad arrives late, he scolds them vehemently. Yū takes the blame, and Guren promises to punish him later, even though he knows Yū is covering for Shinoa.

Guren gives a speech to the Moon Demon Company, and Shigure hands out orders for the individual squads.

At the Ebina rest stop, he summons Yu for his punishment. They chat, and Guren tells him he is glad about Yu's attitude change. Yu also chats with the rest of Guren's squad, finally realizing that Sayuri is his teacher. He recognizes Shinya as well. Moving on, Guren orders Goshi to create a mortifying illusion of a naked Yu screaming for his mommy. Hearing his screaming, the rest of Shinoa's squad charges in, and she breaks the illusion.

After scolding her, he challenges her to a match: Guren, Mito, and Shinya against her entire squad. He gives her ten seconds to prepare.

Guren strikes off against Yū, quickly distracting him with an explosion ward and getting past him to strike Mitsuba and Shinoa. He lectures him. This exercise teaches Shinoa's squad a lesson, helps Shinoa's squad gain focus, shows off the strength of the newbies as three wielders of the Black Demon Series, and raises moral of the troops.

Beginning their mission in Nagoya, Guren's squad charges underground, eliminating vampires as they go. He assigns three squads to each of the eight nobles they are targeting. Shinoa and Narumi's squad are the only group to have only two squads, and he leaves Shinya with them to take over command if something happens to Guren. Guren's squad takes on Nineteenth Progenitor Mel Stefano on their own. Although they succeed, Guren and his squad are pretty bruised and battered. His squad claims he nearly died eight times in that fight, and they decide to use at least two squads in their next attack.

A soldier named Kusunoki reaches Guren, collapsing to the ground and giving him information. He says ten soldiers were killed and another twenty are hostage in Nagoya City Hall. This means that six squads were exterminated while hunting their two vampire targets. Even though this is an obvious trap, Guren's squad goes to reinforce Shinoa and Narumi's squad. He adds a new target to their list: Thirteenth Progenitor Crowley Eusford.

When the Moon Demon Company regroups, he asks Narumi for a report on rookies' teamwork, and Narumi tells them they did very well. Sergeant Aiko Aihara reports that she lost 8/15 of her team, and Guren tells her that is not her fault. Guren orders Narumi Squad and Shinoa Squad to accompany him in exterminating Thirteenth Progenitor Crowley Eusford, Seventeenth Progenitor Chess Belle, and Horn Skuld and rescuing their comrades. Shinya asks him if he is okay after losing so many people today, and Guren says he will just cry later. He informs the squads they will only attack for ten minutes. He orders Aiko to wait half an hour for other squads and to send them to Nagoya Airport.

Once they reach Nagoya City Hall, Guren looks at the hostages being used through a telescope and knows that they are being used as bait to lure them. Yū insists on bursting in and saving them. Narumi dismisses it as too dangerous and when Yū asks him what they should do, Narumi asks Guren what they should do. Guren suggests that they snipe them from their position and see if they can lure them out but says that if there are too many of them, they are to abandon the hostages and run. Yū shouts that they can't do that.

Shinoa interrupts Yū and asks Guren what their priorities are. In order, he says that their top priority is to maintain their numbers, letting no one die. Their second priority is to free the hostages and lastly, getting the hostages out alive. Narumi states that this is because they are needed for another mission after this. Guren then says that they need to keep the vampires occupied in Aichi Prefecture for as long as they can so they can buy enough time for the main forces in Shibuya to get prepared.

He says that once the hostages are free, they need to draw as much attention to themselves as they can and then begin their next mission which is to survive as long as possible. Shinya says that essentially, the plan to actually make alot of commotion only to run away in the end. Guren says that's right and if it goes well, the squads that are finished with their assassination mission will hear the commotion and find them and then they'll kill the vampires holed up in city hall.

After Crowley catches Gekkōin, Guren and his squad discuss what to do while Crowley, Horn Skuld, and the Seventeenth Progenitor Chess Belle wait patiently for them. 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.

Sometime later, Yoichi reports on this situation with Guren's squad to his squad and Yu insists on rescuing him. Shinoa agrees with him but says they only have five minutes. She gives them specific instructions regarding their plan. When Shinya and Guren attempt to flee from Crowlely, Chess, and Horn, Shinoa Squad breaks through the floor below, and Yu attacks Crowley. The vampires easily block and counter the humans' attacks.

Guren orders them to escape, and Shinya agrees. Shinoa orders Yu to leave as well. Guren calls Goshi out of hiding, and Guren's personal squad breaks in through the windows. Goshi creates an illusion, allowing the humans to escape, but they are forced to leave Guren behind.

Crowley orders Chess and Horn to restrain Guren and take him with him.

Natural Abilities
Guren is an intelligent scientist, capable of developing Cursed Gear. He even created a method with a very high rate of success for the development of humans who can bear Black Demon Series weaponry.

He proves himself as a capable swordsman, strategist, and leader on the battlefield. He is rumored to have even recaptured Shinjuku from the vampires with a single team.

Manga

 * "There he is. Just like the prophecy said. One of the lab rats from Hyakuya Laboratories, the company that destroyed Japan. Boy. You are going to be of use to me in exterminating vampires."--Guren to 12-year-old Yū after escaping Sanguinem, Chapter 1, "The World of Blood Legacy"
 * "Sorry, Kid. The army doesn't have use for virgins who are too scared to work in a team, make friends, or date. If you want in, then make a friend at that school and introduce them to me. I'm not holding my breath. YOU FAIL!"--A note from Guren to Yū, Chapter 2, "Humanity After the Fall"
 * "Quit screeching. Nobody wants to hear it, Vampire."--Guren to the escaped vampire, Chapter 2, "Humanity After the Fall"

 * "Okay, listen up. The reason that I, your homeroom teacher, decided to grace you all with my presence today is because we have two transfer students... Anyway, here they are. Yūichirō Hyakuya and Yoichi Saotome. They're the idiot and the crybaby, respectively. As of today, they're joining your class."--Guren to the Moon Demon Company classroom, Chapter 4, "The Worst Pair"
 * "Leave 'em. We won't get anything done in class with them conscious. Right then. The Cursed Gear aptitude test is coming up in a week. It's been a while, but I guess I'd better teach you guys something, eh?"--Guren to the Moon Demon Company classroom after pulverizing Yūichirō and Kimizuki, Chapter 4, "The Worst Pair"
 * "That doesn't matter. Strength alone is not enough. Make friends. Find companions. Don't try to handle everything by yourself. Because if you do... when the demon sinks its claws into you... it will swallow you whole, and you won't be able to come back. Anger and impatience are a demon's favorite snacks. As you are now... you'd be devoured by your own desires and turn into a demon yourself."--Guren to Kimizuki, Chapter 4, "The Worst Pair"
 * "I guess it's time I started making some preparations to steal the throne of this little kingdom out from under the main family."--Guren to Shinoa, Chapter 4, "The Worst Pair"

 * Okay, you two have your Cursed Gear now, so here's your first official Moon Demon Company mission. Yūichirō. Kimizuki. Look at the ceiling. There's a man-eating demon up there. You two go kill it."--Guren to Yū and Kimizuki, ordering them to kill Yoichi, Chapter 6, "Black Asuramaru"
 * "YOICHI! Are you going to hide underneath that bed and watch your family die again?! Get out of here and protect them!"--Guren to a possessed Yoichi, Chapter 7, "New Family"
 * "You have talent. But you feel guilty because you couldn't save your sister. That's sapping your desire to live. But today... you've found enough reason. Your reason to live now... is to protect the ones who saved you today. Your friends. Revenge? Don't let something so petty consume you. That goes for you too, Moron. Forget your old family. Because you have a new family now. Put your life on the line for the ones you see before you. The past is gone. There is only the future."--Guren to Yoichi, Yū, and Kimizuki, Chapter 7, "New Family"

 * "Thanks for your patience. Mind if I ask you to wait just a bit longer, though? It's time for us to take our medicine, see. Do you mind giving us, oh... another 20 seconds or so?"--Guren to Mikaela Hyakuya after reevaluating Mika and Ferid's strength, Chapter 12, "A Very Safe Supplement"
 * "So then, if I told you we're using him in our experiments, would you be angry? Humans are weak. Fragile. Now that the world has ended, what do we have to do to survive? What do we have to do to kill vampires? To eradicate the horsemen? Your sister, Mahiru Hīragi, invented Cursed Gear. How many people were sacrificed in that long process? Without it... do you honestly think humanity would be able to survive? Understand? So quit spewing idealistic crap at me, Little Girl. Or, what... Are you falling in love with Yūichirō?"--Guren to Shinoa about Yūichirō, Chapter 14, "Everyone's a Sinner"
 * "Yūichirō. You remember, right? Who the one who saved you was. Me. Don't forget who was there for you when you came crawling out of the vampire capital. Me. I went out of my way to teach you how to live here. Even how to use a sword. If you feel like you owe me at all, then pay me back today. You live because of me. You are mine. You belong... to my faction. So don't go wagging your mutt tail to the Hīragi."--Guren to Yū, Chapter 16, "Human World"
 * "You're wrong about one thing, though. I'm not your friend. [I am] your superior. The guy you owe your life to. Your surrogate father. Put all those together, and I'm practically a god to you. You can even call me 'papa' if you want."--Guren to Yū, Chapter 16, "Human World"
 * "Sheesh. Did you have to go on a stupid rant about the obvious, you idiot? I already told you... Everyone standing here right now is family. That includes me. Family... works together to bring back family."--Guren to Yū and their squad about Mika, Chapter 18, "Possessed by Mahiru"
 * "So now is the part where you show off your special hostage? Who is it this time? Are you going to torture Shigure, Sayuri, or any of my other aides in front of me?"--Guren to Kureto, Chapter 23, "Ambition in the Demon Army"
 * "Shaddap. I'm not that dumb. I'm scared of who I could lose on this mission. But... we have to answer the call. If we fail, humanity dies. And so, Shinya. Goshi. Mito. Sayuri. Shigure. I want to complete this mission with as few casualties as possible. For that, I ask for your help."--Guren to his squad and Shinya, Chapter 24, "The Moon Demon's Orders"
 * "SHUT YOUR MOUTH, CHILD! This mission is not a game!! If you can't follow even basic regulations, we don't need you! Go home!"--Guren to Shinoa in front of the Moon Demon Company when her squad arrives late, Chapter 24, "The Moon Demon's Orders"
 * "Listen up, everyone. During this mission, I will have zero tolerance for anyone who doesn't follow regulations. Nor will I tolerate anyone treating this like a game or messing around. I repeat, this is not a game. This is the most difficult, dangerous mission we have ever undertaken. Some of us are going to die. We are all family here. And on this mission, we are going to lose a lot of family members. But despite that danger, this is a mission worth risking our lives for! Listen up!! I don't want us just coming home alive... We will come home victorious!! DO YOU HEAR ME?!"--Guren to the Moon Demon Company, Chapter 24, "The Moon Demon's Orders"
 * "It's your punishment. Shinoa. This is your squad. I'm doing you a favor and teaching you that even a little mistake could kill them.... You don't get it. You've never had anyone important to you before. You don't know what it's like to fear losing someone. But now things are different. Even a tiny mistake is enough to kill. Your little pranks could cost your family their lives."--Guren to Shinoa, Chapter 25, "Narumi & The 20-Year-Old Yūichirō"
 * "You have three Black Demon wielders on our team. What the hell was that? You showed very little teamwork. The vampire nobles we'll be facing are stronger than us three. How do you expect to fight them? Or do you plan on standing there, cracking snarky jokes while you die?"--Guren to Shinoa's squad, Chapter 26, "Thirst Logic"
 * "We're going to reinforce Shinoa Squad and Narumi Squad. Once we do that, I'm adding a new target to our list. He's currently located in the Nagoya City Hall. We are going to kill... Thirteenth Progenitor Crowley Eusford."--Guren to his squad, Chapter 28, "Livestock Revolt"
 * "Anyone with a heart cries when a friend dies. But we can't afford to do that right now. We have a mission to complete."--Guren to Shinya, Chapter 29, "Who's Pulling the Strings?"
 * "You idiots!! Why the hell did you come?!  Follow your orders, dammit!!  Get out of here now!!"--Guren to Shinoa Squad, Chapter 33, "Demon's Lullaby"
 * "I'm already done for... Save your strength for getting Shinya and the others out of here."--Guren to Norito Goshi, Guren Squad, and Shinoa Squad, Chapter 33, "Demon's Lullaby"
