Rentaro Mimasaka
A bully to Ashitaba, he is one of the three first visitors to the nurse's office. He was the most wary of Hadesu-sensei. After being made fun of by pretty girls at school, being criticized about his weight, and comparing himself to Fuji, he was possessed by a beauty-stealing Byouma. Hadesu-sensei devours the Byouma and he seemingly becomes friends with Ashitaba and Fuji.
