『Juuji Yusurube』

Juuji/Jyuji Yusurube is an Oni and a student of Rasetsu Academy.

Juuji is a boy with green eyes and hair, wearing glasses and the standard Rasetsu Academy uniform.

Though he outwardly appears to have a more mature personality than others, he is immature with his sexual desires, being slightly perverted and abruptly asking Homare Byogubaura if she would like to "lose her virginity" to him, additionally holding a grudge against Rokuro Kiriyama after witnessing Kuina Sazanami's displays of affection towards the latter. However, in most other situations, he is rational and determined to prove himself useful.
