菅原 桃香

Life Research Club's president and the classmate of the protagonist. She is carefree, lively and very pushy, and the one who pulled the protagonist into the club.

Claims to have created club for world peace because love is peace and love is sex. The other half reason club was created was to over come lust. Momoka mother eloped with another man several years ago. So she didn't believe in forming close or normal attachments when it came to love/sex. She changed her mind about love but was still a free spirit when it comes sex.
