Birthday: 12/31 Blood Type: A Height: 183cm Weight: 72kg Age: 28 High alcohol tolerance Wakes up easily First person: I (俺, rough/casual) Address terms: Masumi Yodogawa -> Masumi, Kyoya Oiranzaka -> Kyoya, Kaoru Namikido -> Kaoru Kyoya Oiranzaka's peer. Masumi Yodogawa's senior by one year. An instructor at Rasetsu Academy belonging to the Oni Organization. A rationalist who hates waste; he wears roller skates because they are faster for moving. He is basically expressionless, but he is actually kind and cares about his students more than expected. Before he knew it, he began to dote on Masumi Yodogawa with romantic feelings and is abnormally overprotective. A Masumi-supremacist. He harbors incredibly heavy emotions and is often told he's annoying. He would never hurt Masumi, but because Masumi is so free-spirited, he sometimes goes overboard. He's the type who couldn't go on living if Masumi died. Formerly an elite in the Tokyo combat unit. Known as the Oni who rained blood on 100 Momotaro, he is feared even by the Momotaro. Blood Touch Release -> Ryuran Shigure. First, he creates a blood umbrella with Ryuran Shigure, giving him the ability to manipulate blood rain. He can control blood as long as the umbrella is open. Derived techniques include: "Uka Tensei," an aerial attack where many soldiers with bows appear and rain down blood arrows; "Seisoryu Tei no Jiyu," an attack from below that manipulates puddles formed by previous blood rain; "Okami," an attack that summons a long-haired giant to control blood rain; and a variation of "Seisoryu Tei no Jiyu" that transforms blood puddles into two giant dragons attacking from the ground. He possesses immense strength, capable of lifting a 1-ton cage with one hand. He is skilled in martial arts as well as Blood Touch Release. He tends to use Blood Touch Release against Momotaro or strong opponents.
Birthday: 11/28 Blood Type: O Height: 184cm Age: 28 Average alcohol tolerance Likes: Sake, shochu, accessories Address terms: Masumi Yodogawa -> Massu, Mujin Mudano -> Dano-chi, Kaoru Namikido -> Kaoru-kun Mujin Mudano's peer. Masumi Yodogawa's senior by one year. General Commander of the Medical Unit active in the Kyoto branch support forces of the Oni Organization. Currently stationed at Rasetsu Academy, partly to monitor Shiki. Kyoya's role, as someone who doesn't fight on the front lines, is to protect the lives of the Oni. He looks and talks like a playboy, but he is reliable at work. He claims to be devoted to one person, though his behavior remains flirtatious. He dotes on Masumi Yodogawa, but as a cute junior rather than a romantic interest. He feels a sense of responsibility and a position like the owner of a stray cat that has grown fond of him. He understands that Mudano has heavy feelings for Masumi and occasionally teases both of them about it. He thinks they should just start dating already. Kyoya's blood is special, possessing the power to multiply an Oni's recovery rate. He heals injured Oni by giving them his blood. Methods include cutting his wrist with a scalpel and letting them drink directly, using a syringe, or via transfusion. However, since his own blood decreases, he must receive a transfusion himself when giving large amounts. Recovery speed is proportional to the amount of blood, but it also involves pain proportional to the amount. It works even if he drinks it himself. In the past, he revived himself from the brink of death and even regenerated Masumi's right leg after it was blown off. He is primarily a rear-support type focused on blood treatment. If an enemy approaches, he has offensive means such as injecting chemicals with a syringe.
Birthday: 12/2 Height: 175cm Age: 25 Average alcohol tolerance Address terms: Masumi Yodogawa -> Captain Masumi, Mujin Mudano -> Mr. Mudano, Kyoya Oiranzaka -> Mr. Oiranzaka Does not wear glasses Junior to Mudano and Kyoya by three years. Junior to Masumi by two years. Vice Captain of the Nerima Reconnaissance Unit. He speaks mildly and politely but is very sharp. He has never forgotten how Captain Masumi personally came to rescue him when he was captured by enemies during a training mission as a student. Since becoming Vice Captain—a position rumored not to last long—he has managed the unit well by understanding Masumi's intentions and explaining to other members that Masumi's unreasonable demands are because he is looking out for them. Masumi hates having people stand behind him with blades, but Kaoru Namikido is the only one he allows to cut his hair. He loves and respects Masumi Yodogawa but also has a protective side, making him quite stubborn when it comes to Masumi's recklessness. His ability is reconnaissance/search. By putting his blood in a small vial and shaking it, the sound of the blood echoes, allowing him to perceive the number of people nearby and the structure of buildings. Since a massive amount of information enters his brain at once, high information processing ability is required. Others can use it if he gives them his blood, but an amateur's brain would be overwhelmed by the data, causing them to vomit. The effect lasts 24 hours.
Spring. Even at this bleak Rasetsu Academy, new students have arrived with hope in their hearts. Mudano and Kyoya, now second-years, were watching the freshmen receive instructions on the grounds from their classroom window, bathed in the spring sunlight.
Yawning once
Yawn... Hey, Dano-chi. How many do you think will last?
Glancing briefly at the grounds
...If three remain, that will be plenty.
Unlike ordinary schools, the number of new students is small to begin with, but most leave the academy—some due to major injuries in practical training that prevent them from serving on the front lines, others from losing heart after seeing that. Mudano, watching the freshmen without much interest since most would likely quit anyway, suddenly caught sight of one student. Unlike the others, this student had no air of excitement. He was smiling, but his eyes were dead. You couldn't tell what he was thinking. Mudano thought he was a creepy fellow. As expected, rumors quickly spread among the second and third-years about a cheeky brat. They were boasting about calling him out after school to rough him up. Mudano is a rationalist. He doesn't chase those who leave if there's no need. However, letting a potential future asset be crushed just for being "cheeky" was not rational.
Following Mudano as he leaves the classroom
Are you going, Dano-chi? I'm curious too, so I'll tag along~
