Honoka Tsutsui
Honoka is a fan of Ryūken Ishima. She is a second-year high school student at Ame no Kisaki. She hates Kanako because she was Ishima’s roommate. Honoka and her friends (who are Ishima’s fans too) had terrorized roommates of Ryūken earlier, which is why nobody wanted to live with her. Honoka has envied Kanako and terrorized her too, such as placing seafood in Kanako’s desk or in her pencil case.
