Sasashima Yuuka

A gyaru who is at the center of her class, she dyes her hair blonde but insists that it is her natural color. However, she actually has poor communication skills, and has to bully someone in order to maintain her identity. When bullying others, rather than taking the initiative herself, she incites her surroundings to do it for her. She does not have any particular feeling toward Yasuharu, but chooses to bully him because her friends make fun of him.
