岡部 久美子

Yuuta's classmate. She has a well-developed, plump body, but her plain personality makes her hard to notice.

For some reason, however, she tends to be the victim of the disturbances Yuuta and his classmates cause.

Basically, she is timid and shy, and is even more preoccupied with her own beliefs. She is in love with Hiroshi, and continues to have naughty fantasies every day.
