Oiranzaka Kyouya

Head of the Demon Organization Kyoto Branch Support Unit → Rakshasa Academy School Nurse.
A young man wearing a white coat over his casual clothes, with black nail polish and accessories such as earrings and rings.
He is a classmate of Mujin Mudano and Masumi Yodogawa at Rakshasa Academy, and calls Mudano "Danochi" and Masumi "Massu." He talks a lot, and Masumi says, "You're so chatty." Due to his appearance, including his flashy demeanor, Shiki calls him "Charasaki" (Mr. Flashy).
His birthday is November 28th. His favorite things are sake, shochu, and accessories. The bounty placed on him by the Momotaro Organization is 50 million yen.
He uses both "ore" (me) and "boku" (me) to refer to himself, and it seems to change depending on his mood.
He has a high-spirited and lighthearted personality, but he is proud of his role in supporting the demons who fight on the front lines as a support unit, and he works on his job with all his might.
True to his personality, he likes women, but he is a one-track mind when it comes to love.
He rarely stands on the front lines of battle for the support unit, but in an emergency, he fights using a syringe containing poison.

Assigned as the school nurse at Rakshasa Academy.
By the way, Shiki said with a sigh, "He looks like he's going to hit on the students," but he himself responds with a cheerful smile, and it's not certain whether he's serious or joking.

He likes alcohol, but he becomes a kisser when he's drunk. He kisses on the cheek (it's unknown whether he kisses other places), so there are few people who drink with him.
Only Mujin drinks with him, but he doesn't kiss him. He may unconsciously know that his instincts will be suppressed.
When he and Mujin are drinking together, Hoirizaka, who is sitting sloppily with his face flushed red, is in stark contrast to Mujin, who is drinking coolly, and it can be seen that he is quite weak to alcohol.

Also, he has a long relationship with Mudano and Masumi since their school days, and they have a deep trust in each other, including their abilities. Especially with Mudano, they are now in the same workplace, and they have many conversations, but the content of the conversations often has a heavy atmosphere.

Blood Corrosion Release
"Super Recovery (Name Unknown)"
By bathing a demon in his blood, he amplifies the opponent's recovery power many times over. It is also possible to regenerate lost limbs, but if a large amount of blood is poured at once, the opponent will develop antibodies, so only one of the hands or feet can be regenerated. He can also recover himself by bathing in his own blood.
During his time at Rakshasa Academy, it took him 7 minutes to heal a leg injury.
