ナオ

Cheerful and energetic, Nao is a tomboy personified. Her family owns a dojo specialized in mixed martial arts, and Nao has trained enough to a point she occasionally teaches the classes herself. When she's not working as a hostess or at the dojo, she goes to university, majoring in physical education. Her reason for becoming a hostess is to get more in touch with her feminine side.

Her real name is Hikawa Minami (氷川 南緒).
