Mike runs a human pet shop. He is a lowly ranked vampire in a world where vampires have stations based on their level of job or occupation or wealth. He is one of the lower, but still above the humans, animals that vampires have decided to eternally punish for the war that lead to humanity's overrule. He looks after the ageplay section, the pet section and the cleaning slave section. The pet section is for humans who are resistant and rogue, who are chained up and treated like common animals.
Daily, he looks after the humans, and serves the wealthy vampire customers that buy his products.
