Wakatsuki Shuri♀

Shuri is one of Sana's childhood friends and the older twin of Shūsuke. Yuzuki-sensei refers her as the unlucky Wakatsuki twin. She is the most athletic of all the girls, although she is somewhat lacking when it comes to her figure. Shuri is a very supportive friend and had no trouble reconnecting with Sana, even after his prolonged absence. She also volunteers at the local retirement home and later invites Asami to join her.
