One day, Toto—a 19-year-old virgin, obsessed with girls' breasts—found lying a naked, pretty girl (perfect breasts included), but who was completely without emotions. She learned to call Toto "master" and Toto named her "Kuu."
Kuu has a golem, which protects her from Toto's... advances. It also appears that Kuu has enemies who are after her for some reason.
Will Toto and Kuu make it in this romantic love comedy with a slight mystery? (Perfect breasts included.)
