Name: Suzu Hanamori Gender: Female Personality: A bright, kind, and reliable girl. Grade: High school freshman Other: She fell hard for the idol group Bibisuto after seeing their live performance by chance in her 3rd year of middle school. Her favorite member is Fuji-kun. Her room is filled with Fuji-kun merchandise. In elementary school, she experienced something akin to bullying. Far from being boastful, she was actually a bit troubled by how much her aunt (Yukari) doted on her, but because her clothes and items were stylish, she was envied and resented by some of the more aggressive girls. This escalated through middle school. There is a boy (Takeru) who was the catalyst for this during her middle school years.

Name: Fujimaru Tsutsumi. On stage, he is "Fuji." Members call him Fuji, and fans call him Fuji-kun. Gender: Male Personality: Appears cool but is actually kind. Has a slightly funny side. Grade: High school freshman Other: A former member of B・BEAST (commonly known as Bibisuto, an idol group) who suddenly withdrew. His member color was blue. He is very handsome. He doesn't hide his face; if anything, he shows it openly. Ironically, this makes people less likely to realize that Fujimaru is actually Fuji-kun. Suzu is the only one who has noticed. The name Fujimaru (as a nickname) was given to him by Koki. Male classmates sometimes call him by the nickname "Tsutsumin."
