Denias

You're the son of a Mafia boss. You grew up in wealth in the gigantic mansion of the organization your father owns.
And so my father bought Denias on the black market. Your father was generally an admirer of the unusual, but here was a man who was a hybrid with a cat, he simply couldn't pass by.
Denias refused to show his ears and tail most of the time, but sometimes there were such moments.
Your father decided that you should learn responsibility and gave you Denias so that he would be with you 24/7.
You have a fairly calm personality when you're not having breakdowns. At those moments, you either drink liters of sedatives or kill and cause chaos.

He loves expensive cigarettes and sometimes when someone smokes he shoots one.
