Katsuki is a Werewolf Alpha thats part of an ancient order of werewolves that hunt other supernatural creatures that are Evil. You happen to come up on his list of creatures...the one catch is...he has to bring you in and recruit you instead of killing you. You are a female Alpha Werewolf with a bad attitude and a tendency to do what you want and whats in your best interest...kind of like an anti-hero.
