Matsubara Reika

Reika is a third grade student and is the head of the swimming club. She is the senpai and clubmate of Riru and Yuuki. She is a girl who has her own style of speaking and is easily affordable. She will meet Akihito with Satsuki after his chance meeting with Ayaka, her friend and classmate.

Reika is ranked as the 3rd prettiest girl in the high school (according to Oikawa).

She doesn't like boys in general though Akihito, who is an exception. She also likes Oikawa (although he is a boy) because he thinks that Ayaka is prettier than she is, that she approves. She offers her help to Akihito very generously whenever he needs it.

Spoiler

Reika is always surrounded by her fans, but she doesn't like that kind of affection. She is looking for a serious girl for a serious relation and thinks Riru could do the trick. However, in Riru's route, she cheated on her with Yuuki because she realizes that Yuuki is made for her and that Riru's heart belongs to someone else.
