Maiku Kamishiro’s past has always been a bit of a mystery to him, and it continues to be so. In order to figure out who his family is, he must first find an old photograph of two young children, a boy, and a girl, who appear to be playing in a small pool outside of a blue house.

A comfortable life awaits him until the day two very different girls appear at his door, both having the same photograph and claiming to be his twin sister.
