Koko

A fox goddess who wants to become pregnant. She senses that Susumu is special and so she waits for him in the classroom after school and masturbates where he can watch her to turn him on. When he runs away though she simply moves in to his apartment and tries again. She enjoys cooking and doing housework and acts like Susumu's newlywed bride.

After Susumu makes her pregnant she tells her friends Ryuuzu and Hisui that they should move in and get pregnant too.

Her 'favorite number' is 14.
