Mitsuba Sangū 「三宮 三葉, Sangū Mitsuba」 is one of the main characters and a concurrent heroine of the Seraph of the End: Vampire Reign manga series. She is a special duty second lieutenant of the Japanese Imperial Demon Army and a member of Shinoa Hīragi's squad in the Moon Demon Company.
She is a girl with long blonde hair tied up in pigtails (her hair appears longer in the manga) and large purple eyes. Mitsuba is noted to have a curvaceous figure.
She wears the standard JIDA uniform which consists of a long-sleeved black coat with a standing collar which has a red bow tie around it and has her sleeves rolled up. The coat has two rows of gold buttons on the front, light green details including the shoulder epaulettes which has a Sam Browne belt passing diagonally over her right shoulder. Rather than the standard white gloves, she wears black gloves and a white web belt with a gold waist-plate. She also wears the standard black skirt (with black shorts underneath) and knee-high black boots. She sometimes wears the black cape.
- Anime: In the anime, she wears the standard white gloves instead of black.
Mitsuba is shown to be a serious and by-the-book soldier, who dislikes those who break the formation and commit to individual action. She tends to have a fiery personality and may be the most talkative of the group. In her previous squad, she once broke the formation of her team in order to save a teammate, which lead to her squad's annihilation. This makes her value staying in formation and following the rules, which she enforces on the rookie soldiers below her. Also, because of this, she didn't want Yūichirō to save her when she was caught by the vampires, thinking that he would die if he tried. However, Yu saves her life and Mitsuba learns to have more faith her in comrades instead of restraining their actions with her fear.
Mitsuba is proud of her family, yet she hates the fact that she's given special treatment and advantages just because of her family name. Since she's a Sangū, Mitsuba feels that she has to uphold her family's reputation all the time, and despite being second-in-command in Shinoa's squad, feels as if all of her teammate's lives are her responsibility. Even when she slaps Yu for breaking the team formation, she did it because she feared that Yu would have been killed, just like how her previous squad leader died. Mitsuba has an inferiority complex towards her older sister, Aoi Sangū, as she feels under-accomplished when compared to her sister.
Mitsuba is shown to be confident of her skills. She boasts to her squad that she had joined the Moon Demon Company at the age of 14, and is shown to be annoyed when Guren puts her in Shinoa's squad, claiming that Shinoa is not fit to lead, which is dismissed by Guren, much to her chagrin. However, as time worn on, Mitsuba is shown to ease into her role of second-in-command, accepting Shinoa as her squad leader.
Mitsuba joined the vampire annihilation force when she was thirteen. In 2017, when her comrade Shirō was in danger, she broke formation to save him from a Horseman of the Apocalypse. When she slashed its arm to save Shirō, the monster used its other arm to strike her, but her squad leader saved her by using himself as a human shield, which caused his death. This still haunts her even today.
Story: Vampire Reign
Mitsuba first appears in chapter 8 yelling at Guren for putting her on a squad of rookies and, better yet, assigning her to work under Shinoa. Mitsuba and Shinoa draw their weapons, and Guren scolds them. She makes it clear she hates short-sighted people who break formation when she attacks Yū right off for saying he will charge after a vampire no matter what. She is the fifth and final member of Shinoa's squad.
Despite her initial abrasion, she quickly starts lecturing Shinoa's squad on the world around them.
When they see a Horseman chasing a human girl, she orders the squad to stay back, and Shinoa agrees. They explain that the girl is obviously bait. She regrets not being able to do anything, but she understands this is for the best. Yu disobeys and charges in anyway, and the vampires attack on cue. The squad supports Yu and saves the girl, but Mitsuba slaps Yu afterward for his insubordination. Shinoa advises Yu to not take it personally because Mitsuba also has a painful past. She refuses to divulge more information than that.
Chapter 9 opens up to Mitsuba and Shinoa showering. Shinoa manages to cool down Mitsuba's temper. She tells Mitsuba that acting against orders was not the cause of her squad's demise. Mitsuba orders Shinoa to stay in her own shower, and Shinoa takes that as an opportunity to attack.
Shinoa's squad enters the Omotesando Station to exterminate vampires. As they begin, she scolds Yu, and Yu informs her that he even waited for orders this time. He protects her, surprising him with his strength. As she orders the squad to form up, the vampires ambush them. Unlike what the child they saved told them, there were actually nine vampires total instead of only seven. When a vampire grabs her, she does not hesitate to order her squad to escape and leave her behind. Disobeying her orders again, Yu saves her life. They exterminate the vampires.
Yu tells the child's father a little about his past. He explains that he and his friend tried to escape a vampire city, but he left them behind to die so that he could get away. Mitsuba asks him if that story is true, but Yu tells her to not pry or dig into his past. She attempts to tell Yu thank you, but she becomes too embarrassed.
Once they reach the 5th Street intersection, they face off against more vampires--one of which turns out to be Yu's family, whom he left behind in the vampire city to die. The vampires easily defeat the humans before the humans can retreat, and Seventeenth Progenitor Chess Belle bites Mitsuba and drinks some of her blood.
After Yu wakes up from a week in a coma after transforming, Mitsuba is the third to barge into his room. She sees Yu touching Shinoa's neck and Shinoa blushing fiercely, but they say that he was just looking at her bite mark. Kimizuki bursts in next, telling them to be quiet.
She receives a promotion in the next chapter to Special Duty Second Lieutenant. She rants about what an insult that is to Yu and complains about how weak she is. Yū says he is not laughing at her and manages to calm her down. He says she can use that promotion to help him reclaim Mika. She warns him that the Hīragi are scary people, and Yu heads into his meeting. She meets with Shinoa, who calls her a useless lump to Mitsuba's face. Mitsuba says that does not make her mad because Shinoa is the only one who ever had the guts to say that to her face. That chat about the Hīragi and Yu going berserk. The three boys exit the building, beaten and bleeding with the exception of Yu. He yells at Guren to teach him how to use his Cursed Gear properly.
In order to proceed with Cursed Gear training, Mitsuba, Yoichi, and Kimizuki arrive to the meeting location half an hour early, but Guren, Shinoa, and Yū are already there. Shinoa and Mitsuba begin teaching the boys and move into the ruined city. Mitsuba spars briefly against Yū, demonstrating manifestation. Shinoa and Mitsuba explain how this works, and Yū goes first. While waiting on him, the two girls tease Kimizuki for being so kind and ship him and Yū as a yaoi couple, ending their skit with "to be continued." Kimizuki does not approve. Kimizuki goes after that, and the two boys spar. Shinoa and Mitsuba realize that these three boys may be Guren's handpicked secret soldiers, and the power struggle between the higher-ups may begin soon.
Shinoa's squad meet in Shinoa's room in the barracks, and Mitsuba "helps" Shinoa cook breakfast. By adding sake to an omelet, Mitsuba accidentally starts a fire, and Kimizuki soon arrives to save them. She learned from a book that adding sake to food and lighting it is supposed to make food better. Kimizuki takes over the cooking, and both girls are ashamed of their incompetence. They decide to remain loyal to Guren and look out for one another.
On the drive to Nagoya, Mitsuba teams up with Shinoa to prank Yū and then Kimizuki. These pranks make them late, and Yu receives punishment in the following chapter. Shinoa and Mitsuba briefly explain their abilities and make a plan when Guren, Mito Jujo, and Shinya attack their squad to teach them a lesson. She summons decoy demons to split up Mito and Guren, but Mito punches through them. Guren gets past Yū and stuns her, quickly winning the match.
As they prepare for their mission and meet Narumi's squad, Mitsuba teams up with Kimizuki to scold Yu and make him behave and be polite. They attack Fifteenth Progenitor Lucal Wesker. Mitsuba distracts Lucal from Yu, but he destroys her decoys with just a swipe of his hand. She also helps Shinoa distract him when he charges in to kill Kimizuki. Yu cuts Lucal in half, and Narumi finishes him off.
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.
They reach Nagoya City Hall, and after Crowley catches Gekkōin, Guren and his squad discuss what to do. 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.
Sometime later, Yoichi reports on the situation with Guren's squad to the 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.
Yu breaks through the floor and attacks Crowley Eusford. Crowley blocks easily and moves to decapitate Yu. Kimizuki parries the attack, and Mitsuba distracts Crowley by summoning dummies with Tenjiryū. Yu uses Asura Kannon, but Chess and Horn immediately step in and defend Crowley from it. Chess and Horn counterattack and rip apart the shield Mitsuba forms with Tenjiryū.
They rescue Shinya Hīragi and are forced to escape, leaving Guren behind.
After his flashback, Yu wipes away his tears and states he cannot follow orders. He says he is not cut out for teamwork. He tells the others to proceed without him, and he will stay behind. Mitsuba along with Yoichi is shocked by this.
After Kimizuki captures Yu after he fights Crowley, he joins with the rest of the squad, they run toward Shinya, who orders them to move. Vampire reinforcements are coming. They join with Narumi Squad and many injured soldiers. They flee, and Rika Inoue reports seeing a single vampire straight ahead. Shinya says they can handle one noble and orders them to keep pushing forward.
As Mika engages the Moon Demon Company, Shinoa calls out to Mika to identify him, but he tells her to shut up and return Yū to him. Kimizuki says the should stop him before Mika kills them. Yoichi protests. Mika reaches for Yu. Mitsuba tries to block him, but Mika smacks her axe away. Kimizuki drops Yu while trying to block Mika and says Mika cannot have Yu. Mika throws him aside. Mika begins to lift Yū from the ground, but Yoichi jumps on his back. He says he is not letting Mika go anywhere, and Mika tells him to quit getting in his way. Yoichi says Mika can kill him, but Mika is their family so long as he is Yūichirō's family. Mika knocks him off as well, telling him to not be stupid and to die.
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. With her back to Mika, she explains that Yu would be mad at them if Mika were to die. She orders Mika to take Yu and run.
The other soldiers demand to know what she thinks she is doing and say they must kill that bloodsucker.
Kimizuki, Mitsuba, and Yoichi join Shinoa, stepping between Mika and the other humans as well. Yoichi says that they've already decided on their motto: "Family takes care of family." The squad then charges at the Moon Demon Company while Mika flees with Yu.
Shortly after Mika flees with Yu, vampires rain down around the Moon Demon Company. After seemingly escaping the vampires, Shinoa and her squad, sans Yu, run in Nagoya Airport for their rendezvous. Mitsuba says the attacks against them have stopped, but the vampires are most likely still pursuing them. Kimizuki asks Shinoa if she has more information on their assignment.
Later on, a van pulls up at Nagoya Airport, and Aoi Sangū steps out. Although she notices Mitsuba, she quickly turns from her. Then, Kureto Hīragi steps out. Shinya and the members of Guren's squad are immediately alarmed, surprising Narumi with their reaction. Yoichi and Kimizuki recognize Kureto as the one who tortured them.
After Kureto orders Aoi to kill the "sacrifices", Shinoa orders her squad to quickly prepare to retreat.
As Aoi launches chains from the ground, a pair of chains strike down at Narumi from above, but Mitsuba and Kimizuki block the attack. Kimizuki yells at him to not give up yet. Yoichi fires arrows at Kureto, which Kureto easily deflects. Shinoa and Mitsuba order a retreat, and Shinoa commands them to take their curse stimulant pills.
Yu and Mika arrive surprising Shinoa Squad and Narumi.
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 Ichinose Squad will back up the children. He orders them to run. Fighting through their enemies, the children flee.
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 his cursed gear.
As the squad makes their escape from Nagoya Airport, Shinoa tells her squad that they are now seceding from the Japanese Imperial Demon Army.
Three months later, the group is near the sea.
Shinoa, Kimizuki, and Mitsuba listen to Yu and Mika's exchange from outside.
Horsemen then attacking the village. With the exception of Makoto, the group fights four Horsemen. Afterward, the villagers thank them.
Makoto arrives with food he found in a supermarket two kilometers southwest.
Their group notices that Mika drank their blood and approach him. Yoichi asks if their blood was okay. Mika says it was gross. Shinoa rambles about the pure and sweet blood of a virgin and then asks if unchaste blood got in there before looking at Mitsuba with an aghast expression. Yu, Mika, and Shiho share identical blank expressions.
Shinoa brings up their future plans. Mitsuba summarizes what has been going on. She says that the Japanese Imperial Demon Army will probably hunt them down and kill them, which puts the villagers at risk. They mention they cannot travel overseas because of how acidic and poisonous the blood-red oceans are. Monsters even worse than Horsemen swim in their depths.
They suggest surrendering, and Mika rejects the idea of returning Yu to the army to prevent him from becoming a demon. Makoto tells him to keep his fangy mouth shut unless he has any other options. He says he will save Yu no matter what in order to give his friends' deaths meaning. Shiho states he will do absolutely anything to save his sister and even betray the rest of them. Yu suggests meeting up with Guren, but Shinoa vetoes that idea and says they cannot trust him. Makoto tells Mika this is the circle of discussion they are stuck in and asks if he has anything to offer.
Mika asks if he owes them a favor because they gave him blood, but Shinoa says no. She says that blood was for helping a friend but says she would love to hear any suggestions if he has them.
Mika says the vampire queen, his sponsor, participated in the Seraph of the End experiments. They may be able to trust her. He says she was captured and he does not know what happened to her, but rescuing her might be their least complicated option. Makoto asks if vampires are less dangerous than the Demon Army, and Mika says yes. Vampires actually care little about humans and are only concerned by power-hungry humans. Makoto agrees and says that describes the Demon Army pretty well. Shiho also agrees with that plan and states he does not trust anyone aside from those standing right there. Mitsuba agrees to the plan, and Shinoa says that the Demon Army is the most dangerous organization in Japan.
Shinoa announces their next objective is to rescue Krul Tepes before Yu becomes a full demon.
Crowley later arrives at the village. Crowley lands in front of their group and quickly races between them to strike Mitsuba's shoulder with his sword and send her flying. Mitsuba is shocked to realize she is uninjured. He throws her to the ground.
She latches onto Crowley’s leg and orders the squad to abandon her and flee since they cannot waste time there.
Kimizuki manifests Kiseki-Ō and begins his count of nine. Crowley considers pulling back and asks if Mitsuba would release his leg. When she refuses, he says he will just cut off her arms. She declares she will no longer be the weak link.
Shinoa Squad goes onto the bus and Mitsuba wonders if they really should have. Shinoa says there was no other way and Ferid has Akane as a hostage. Mika claims Ferid is controlling them and they shouldn't be involved with him.
Ferid informs Narumi that he has his squad in Ferid's mansion and Shinoa notes Ferid has more hostages. Ferid tells the group that Guren caused the apocalypse by reviving his squad and Shinya and has been burdened by the price humanity has paid.
Mitsuba and Shinoa are in a bathroom and Shinoa makes fun of Mitsuba for taking forever. Mitsuba claims she was looking for an exit but Shinoa doesn't believe her. Mitsuba asks if Shinoa believes in Ferid's story about Guren but Shinoa states that Guren and the army are equally untrustworthy.
Mitsuba meets the others in the men's bathroom and they wonder how long they should trust Ferid.
Shinoa Squad exits the bus and are surprised by the vampires there. Yuu yells at Ferid for making it a trap but Ferid tells him to shut up or else they will all be killed.
Mitsuba backs away as Ferid nearly kills Kimizuki by drinking his blood and wonders if anyone else wants to. Urd asks who the humans are and Ferid replies they are his favorite humans.
Mitsuba watches Kimizuki as he asks for meat and is anemic. She gets mad at Yuu for thinking about leaving, saying that will draw attention. She watches Yuu and Shinoa discuss what is currently happening.
Shinoa Squad goes to Ferid's Mansion and Crowley leaves to unlock the door. The group marvels at how large his mansion is and Narumi and Mikaela argue about the seraph of the end. Tenth Progenitor Fuola Honte appears and cuts Mika's arms off. Mitsuba uses Tenjiryu to retrieve them and holds them until they reattach.
Shinoa is glad that they have an ally who is strong but Mitsuba questions if he truly is their ally. Crowley challenges them to see if their formation can beat him but they are quickly defeated.
Crowley says they must be able to get stronger quickly to rescue Ferid because the one in their way is a fifth progenitor.
