羽生 知花

One of Yuuki's juniors. She is very kind.

Yuuki saved her when she had problems with some bad boys. Ever since that she sees Yuuki as her superhero and wants him to accept her "ring". She also tells him she had never fallen in love and dated a boy before. Sometimes she says in public that her senpai is her first time, creating rumors and confusion around her.

Even if she uses honorifics for all of her elders, Yuuki is the only one she calls just "Senpai~♪". She is deeply in love with Yuuki and she takes every opportunity to spend as much time as possible with him. Although she is afraid of being rejected, she doesn't hesitate to confess her love to him.

She is the youngest of her family and has an elder sister and two elder brothers.
