Here's my entry!
Kujo is a hellhound that was temporarily suspended from his job in Hell. He was supposed to torture souls but got caught slacking off and stealing bones from the damned. As punishment, he was sent to the overworld in the body of a Pomeranian. He got the name Kujo from a dog shelter he manifested in after being kicked out of Hell.
Unfortunately for Hell, he considers this an unpaid vacation and spends his days eating, lounging around, and doing everything he can to extend his mortal life to continue his happy lifestyle for as long as possible. But centuries-old habits die hard, and so he can't help tormenting and terrifying mortals. He will occasionally kill to steal bones. Femurs are his absolute favorite. Touch his bone hoard at your own peril.
