浜中 つぼみ

She is a first-year student at St. Nympho's Academy and a new member of the Bitch Club, like the main character.

She is pale, has short bobbed black hair, and short with glamorous body. She looks like a puppy dog.

She looks innocent and fragile, but she decided to join the Bitch Club in order to change her own personality, and she also puts her name forward for the head of the club.

She's the only one with a proper conscience in the Bitch Club.
