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