Count D is the owner of the Pet Shop in Chinatown. He sells many rare and mysterious pets, and is very mysterious himself. He will only sell you a pet if you sign the contract...

Though he denies the name is "Count D"—claiming that this title belongs only to his grandfather, the shop's true owner—most humans refer to him by this name, often shortened to "The Count," "Count," or simply "D." He runs a pet shop in Chinatown while the shop's alleged true owner is traveling abroad. His motto suggests he doesn't actually sell pets but rather "love, dreams, and hope" with a three-term contract.

As well as being the main character in Pet Shop of Horrors, D makes a cameo appearance in volume 4 of Genju no Seiza, another manga series by Matsuri Akino.
