Yuki to Matsu

On a dark and freezing night, Dr. Sho-an drags home the body of a beautiful man he found buried in the snow. Corpses fetch a high price when turned into medicinal ingredients, and the doctor hopes to rake in a tidy profit to support his practice. Much to his dismay, Dr. Sho-an discovers the man is still alive, and he brings him back from the brink of death. But the doctor's disappointment melts away when his corpse-cum-patient shows him the many delightful uses of a living body! Although Dr. Sho-an only knows his patient is ex-yakuza, the doctor gives him the name Yuki and tells him to make more corpses for him. Instead, Yuki moves in with the doctor and defends their home with his body and sword. (Source: Futekiya)
