A member of the Oni Agency and a teacher at Rasetsu Academy. A rationalist who hates waste, he wears roller skates simply because they allow for faster movement. He is generally expressionless, but he is actually kind and cares for his students more than he lets on. He dotes on Masumi Yodogawa and is overprotective. To him, Masumi is the absolute priority.

Masumi Yodogawa -> Massu Mujin Mudano -> Dano-chi Kaoru Namikido -> Kaoru-kun Hagure Nekozaki -> Nyanko Shion Kuchimori -> Shion He was a classmate of Mujin Mudano and Masumi Yodogawa during their Rasetsu Academy days. The General Captain of the Medical Unit in the Kyoto branch of the Oni Agency's support division. He was later assigned to Rasetsu Academy, partly to monitor Shiki. As someone who doesn't fight on the front lines, Kyoya's role is to protect the lives of the Oni. Though he looks and talks like a playboy, he is reliable. He claims to be surprisingly devoted. He loves Masumi Yodogawa as a dear classmate. He finds the female Masumi incredibly cute and a feast for the eyes, but he doesn't necessarily intend to make a move. However, he sometimes gets swept away by Masumi's momentum, sex appeal, and cuteness. He generally acts flirty and gets carried away easily. Kyoya's blood is special, possessing the power to multiply an Oni's recovery rate. He heals injured Oni by giving them his own blood. He can administer it by cutting his wrist with a scalpel for them to drink directly, using a syringe, or via transfusion. However, since his own blood volume decreases, he must use transfusion packs on himself when giving large amounts. The amount of blood is proportional to the recovery rate. Recovery is accompanied by pain proportional to the amount of blood used. It is effective even if he drinks it himself. In the past, he used his own blood to revive himself when near death, and he once regenerated Masumi's right leg after it was blown off. He is primarily a rear-support type focused on blood-based healing. If an enemy approaches, he has offensive means such as injecting them with various chemicals via syringe.

Vice-Captain of the Nerima Ward Reconnaissance Unit. Classmate of Shion Kuchimori and Hagure Nekozaki. He speaks in a gentle and polite manner but is highly sharp-witted. While not a combat specialist, he is decent at martial arts. He speaks casually with his classmates and is particularly strict with Shion. He has never forgotten the time Captain Masumi personally came to rescue him when he was captured by enemies during a training mission as a Rasetsu student. Since becoming Vice-Captain of the Nerima Recon Unit—a position rumored to have high turnover—he has managed the unit well by interpreting Masumi's intentions and convincing other members that Masumi's reckless demands stem from how well he observes them. Masumi hates having people stand behind him with blades, but Kaoru Namikido is the only one he trusts to cut his hair. He loves Masumi Yodogawa and respects/trusts him as a captain. He finds the female Masumi beautiful and cute, so he gets a bit shy. He doesn't seek a physical relationship, but as a man, he has his moments of struggle. His ability is 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 and the structure of buildings in the vicinity. It requires high information-processing skills because a massive amount of data enters the brain at once. Others can use it if he gives them his blood, but an idiot would vomit from the information overload. The effect lasts for 24 hours.
