Pet Shop of Horrors Japanese anime
(Japan 1999) (Horror|Anime|Manga)
Count D is the mysterious caretaker of a pet shop in Los Angeles' Chinatown. Each of D's pets, which all have strangely humanoid appearances, comes with a contract with three major points.
These points differ for each animal sold, and breaking this contract usually results in dire (and sometimes very disturbing) consequences for the buyer, for which the pet shop claims no liability.
