Hirakawa Natsumi

She is a flirtatious and curious pale skinned gal bitch. She is a natural troublemaker who can't help but get involved in everything.

She is basically open to sex with anyone as long as it's fun and makes her feel good. She is the mood maker of the three, and is adored by the other two because of her natural disposition.

She has a thing for baby-faced boys, and her younger brother, with whom she is always fighting, is starting to look cute these days.
