Tsumugi Himeno

She was a member of the Judo Club before Michi and her friends entered the school and joined the club. Due to the retirement of her senior, Tsumugi was the only member of the club, so she retired and spent her free time working part-time at a convenience store. She has been running and trying to maintain her fitness during her retirement, and after seeing Michi's lively Randori and seeing her classmate from junior high school, Shiraishi from Kasumigaoka, who also postponed her retirement because of a match with Michi, she decided to rejoin the club to enjoy her remaining time in club activities. She is in the 57kg weight class and is almost as tall as Natsume. Although dyeing her hair is prohibited by school rules, she is very smart and uses a black wig to disguise it from Gondo's eyes. After graduating from high school, she went to a university in Tokyo and started living alone.
