Kureha is the younger sister of Kinjirō, who is a first year in high school and loves martial arts just like her mother. She is a member of the crafts club.
After watching and following Kinjirō and Konoe, believing him a male pervert cross-dresser, attacks Konoe to reclaim Kinjirō, only to be quickly defeated in turn. After this incident, still believing her a male, she has fallen in love with Konoe, much to Kinjirō's chagrin. While tomboyish most of the time, she tends to try and act feminine when Konoe is around
