Garnet in the Rough

Kanae, a hitman, is attacked by Sara, a half-vampire, near a trash dump. With no attachment to life, Kanae is apathetic to having his blood sucked or being followed home. Sara was treated as a defective vampire and discarded by his progenitor. Starving for blood, he makes Kanae a proposal: "I'll take care of your degenerate life, and in return, you'll be my food supply!" Because of the arousing effects of bloodsucking, the two begin a physical relationship. As they discover the warmth of touch, they begin to melt each other's loneliness... This is their tale of finding love in a brutal and despicable world. (Source: Animate International)
