Fujimura Sakurako

Hometown: Hokkaido
Likes: Sewing
Dislikes: Studying, listening to scary stories
Favorite things: Chatting, her brother

Hiroki's non-blood-related sister. She is very energetic and short-tempered, but also honest especially when she's with Hiroki, due to having been together with him for ages already. The only thing she's good at is sewing due to having done it ever since Sakurako was a child. Fights often with the other girls who approach Hiroki.
