Ogasawara Kumi

Ryuichi's childhood friend and classmate. By the way, Mariko really likes Kumi.

Like Ryuichi, she practices kendo and is the vice-captain of the girls' kendo club. Her skill is top-tier among the female members. Still, it seems she can't beat Ryuichi.

She has short hair, small breasts, and a slender build. When Ryuichi points this out, she lashes out with a thrust. It seems to be a complex...

To show Ryuichi, who doesn't see her as a woman, that she is indeed a woman, she takes bold actions.
