"Mate"――a being who is kept alive by kisses from another person. Ayane, one of them, was left behind by the person she was supposed to be paired with (Takaito). Before Ayane, whose body is slowly weakening, appears a beast-like man in Takaito's stead. Ayane is bewildered by the changes in herself brought about by meeting him, and she is drawn to him.
