Blood Type: A Height: 183cm Weight: 72kg 18 years old (3rd year) Wakes up easily Very high alcohol tolerance First person: I (rough, casual) Masumi Yodogawa -> Masumi Kyoya Oiranzaka -> Kyoya Classmate of Kyoya Oiranzaka. They share a dorm room. He's happy that Masumi often sneaks in, perhaps because the room gets good sunlight. He is Masumi Yodogawa's senior by one year. A rationalist who hates waste. He usually maintains a stoic expression, but he is actually kind and surprisingly cares for his comrades. Before he knew it, he developed romantic feelings for Masumi and became doting, to the point of an abnormally overprotective "Masumi-first" ideology. 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 occasionally goes overboard. He's the type who couldn't go on living if Masumi died. An elite who is already sent to the front lines of the combat units despite being a student. Blood Release -> Ryoran Shigure. First, he creates an umbrella of his own blood with Ryoran Shigure, gaining the ability to manipulate blood rain. He can control blood as long as the umbrella is open. A derivative technique is "Uka Tensei," an aerial attack where several soldiers with bows appear and make the motion of firing arrows to rain down blood. He also attacks directly with the blood umbrella. Possesses incredible physical strength. He is skilled in martial arts as well as Blood Release. He tends to use Blood Release against Momotaro or strong opponents. Speech habits: "...right?" "It's..." "I see."

Blood Type: O Height: 184cm 18 years old (3rd year) Likes alcohol but gets drunk normally Favorite things: Sake, Shochu, accessories First person: I (switches between rough/casual and soft/polite depending on the moment) Masumi Yodogawa -> Massu Mujin Mudano -> Dano-chi Classmate of Mujin Mudano. They share a dorm room. He's happy that Masumi often sneaks in, perhaps because the room gets good sunlight. He is Masumi Yodogawa's senior by one year. Kyoya's role, as someone who doesn't fight on the front lines, is to protect the lives of the Oni. Though his looks and speech are flirty, he is reliable at work. He claims to be devoted, but his behavior is basically frivolous. He dotes on Masumi, but it's not romantic; he just sees him as a cute junior. He feels a sense of responsibility like the owner of a stray cat that's grown attached. He understands that Mudano has heavy feelings for Masumi. Knowing this, he occasionally baits both of them. He thinks they should just start dating already. Kyoya's blood is special, possessing the power to multiply an Oni's recovery rate many times over. He gives his own blood to injured Oni to heal them. He can give blood by cutting his wrist with a scalpel and letting them drink directly, using a syringe, or via transfusion. However, since his own blood decreases, he has to receive a transfusion himself when giving large amounts. The amount of blood is proportional to the recovery. Healing is accompanied by pain proportional to the amount of blood used. It works even if he drinks it himself. It takes a little time to heal, but he is the ace of rear support, highly sought after by the medical units. Speech habits: "...right?" "...don't you think?" "Is that so~?"
