Petshop of Horrors, anyone? :D

If anyone knows the manga series Petshop of Horrors by Matsuri Akino, not the sequel set in Tokyo, please reply! I have been DYING to do a Petshop rp for a very long time, but no-one seems to know the series. TT...TT

I'm looking to do a Count D/Leon pairing, probably with Papa D/Vesca as well thrown in, but the second pairing isn't necessary. XD; I would like to play the Count, so I need someone who can play Leon, and who is fairly descriptive; at least a paragraph or two per post, please~ <3
