Sakuragawa Mirai

Minato's twin sister, and the older sibling.

Mirai is strong-willed, and has been appointed the "leader" of her group of friends. (which includes herself, Yachiyo, and Marin.) She loves Hiroaki and clings to him a lot, trying to help him with his work. But she's also very tsundere, and gets flustered easily.

She's a very active girl who likes energetic activities.
