[Suzerain of Sheol]

So far, I have Valvatorez, a former vampire tyrant who lost his powers in a promise he made long ago (he has a thing about not breaking promises...) and is obsessed with sardines, believing they'll give him back his powers. Fights with either spears or swords.

Then there's Fenrich, his werewolf steward and second in command, who is just an all around snarky badass, but he seems to have a hidden agenda of some kind. He uses fists or axes.

And, the main antagonist so far is some girl who failed to become a prinny when she died, is convinced she isn't dead and is instead dreaming, and wants to exterminate prinnies for some reason. Her name is just ???? at the moment.
