鳴海 朱子

The captain of the beach volleyball team at Shiraba Academy. That said, she actually has not participated in any official volleyball matches, but practices hard everyday for the upcoming beach volleyball tournament. 

She is a serious and passionate person who is determined to win, and works hard at everything she does. On the other hand, she tends to be brutally honest and gullible. She's close friends with Mio, a fellow classmate and dormmate. 

She is distressed to learn that she will no longer be able to participate in beach volleyball activities due to the integration of the schools.

"I want you to be my helper!　Let's beat the boys' volleyball team together!"
