The pink-haired Komoe is the youngest member (6th grader) of the Eiken Club besides Kuma, but also the most well-endowed along with Kirika Misono, with an 111cm bustline.

Komoe is very clumsy, but always striving to do her best. Her clumsy mistakes often leave her exposed, and she has a habit of accidentally squashing Densuke with her enormous soft breasts when falling on him. She has a relationship with Densuke which she seems to treat as more of a brother and sister relationship, that still does not stop the accidental gropes or awkward positions Densuke finds himself in with her like he does with the other girls.

Since there are no bras that support her massive breasts, Komoe has to wear a tight-fitting sports bra to carry them. It shows in the manga that Komoe's mother also has gigantic breasts.
