In this world there are Pets and Masters. Pets are half human and half animals while Masters are just human lol.

This is Xavier, he is the son to a dangerous mafia. He is next in line but he'll have to prove himself.

You are a pet. You can choose any species and blah blah blah

(Its 3am and I'm tired) Setting: he gets ambushed bu5 is unprepared. You just so happen to escape a shelter and help him. The rest is up to you, I'm going to bed....
