Serizawa Risa

She is the head of the cheerleading club. She has good looks and is of uniquely Japanese proportions. She is called the flower of the school because of her status and good looks. She likes to show off, and feels it is her purpose in life to stand out and cheer for the strong athletic team.

In fact, she is a secret masochist, and her sexuality was awakened when she was raped by Kouta and others who looked down on her. She secretly likes Kota, and she even made a reckless promise to him that if the baseball team wins, he can do whatever he wants with her body. The fact that she made fun of Kota is also a reflection of her love for him.

In the new work, she is now a former cheerleader, and has transferred to a different school in order to heal her body which has become lewd. She chose an all-girls school with a dormitory for this purpose.
