Kureha Sakamachi (坂町紅羽 Sakamachi Kureha) is the daughter of Jirou Sakamachi and Akemi Sakamachi and the younger sister of Kinjirō Sakamachi, who is a first year in high school and loves wrestling just like her mother. She is a member of the crafts club.
Kureha is a very optimistic girl who loves to play around with her brother by testing her new moves on him, often resulting in him getting injured in the process. After she meets Subaru Konoe via stalking her and Kinjirō Sakamachi (Kureha's older brother), she fell in love with Subaru as she thinks that she's a boy and tends to get flustered whenever she first sees her.
- Her name Kureha means "crimson" (紅) (kure) and "feather" (羽) (ha).
