The cool, smart-girl type, Ritsuko believes in theory more than her own inner strength. Originally an intern working at 765 Production after graduating from high school, due to a lack of girls scouted by 765 Production Ritsuko became an idol herself. Though despite being an idol, she still has one hand in the business side of her own celebrity, and is quick to chide the Producer if she thinks he isn’t doing his job right. Also, Ritsuko’s appearance remains conservative and business-like, as she always wears glasses and keeps her hair in two modest pigtails. No matter the costume or event in the game, she never takes her glasses off, or lets her hair down.
