Pet Shop of Horrors

Pet Shop of Horrors is a Japanese horror manga created by Matsuri Akino. The series focuses on the eccentric Count D, proprietor of a mysterious pet shop located in the heart of Chinatown, and the numerous patrons who visit his shop.

Plot
Count D is the mysterious caretaker of a pet shop in Los Angeles' Chinatown. Each of D's rare pets, which all have strangely humanoid appearances, comes with a contract with three major points. These points differ for each animal sold (although each animal's contract includes not showing it to anyone), and breaking this contract (something the buyer almost always does) usually results in dire consequences for the buyer, for which the pet shop claims no liability.
