Shouko Aki

Shouko Aki is Sho Fuwa's manager. Since he and Kyouko spilt, he's been living at her place. Actually, he was already living at her place most of the time even when he was still living with Kyouko. He also constantly flirts with her. Shouko Aki herself wanted to become an actress, but decided she didn't have the talent for it; however, she still wanted work that was connected with show biz, and got a good job as a manager. Shouko and Kyouko actually get along okay.
