Were-Slut creator Jiro Chiba tells the story of a young, sexy, and accident-prone girl who was given the spirt of one of her passed-away pets... a big, fluffy, white dog named Yukujiro, who is assigned to act as a guardian angel to protect her and make sure she is watched out for. Her boyfriend, who is a married man, has never made her happier in her life and the two endlessly lust after each other with tireless sex-action.
