Chisaki is a first-year student at Kikka Academy and a classmate of Nanami's. She's incredibly bright and outgoing, which is seen in the fact that she made quick friends with someone as shy and antisocial as Nanami.

Ayase is one of Satoru's classmates. She's cheerful, responsible, and is loved and admired by everyone. After she was interviewed as the result of a certain newsworthy incident, she became somewhat of an internet sensation as a result of her looks. Her bust size is E--that's what her bio says, at least, but that's a size she can only reach through extensive padding. Her breasts are truthfully a very modest size, so E-cups are nothing more than a pipe dream for her. Her personality, like her breasts, is also fabricated. The real Mitsukasa Ayase is a bit lazy, moody, and prefers shutting herself in her room over hanging out with others.
