Leviathan is a pro gamer whos obsessed with you, he gets jealous when you interact with other characters..and even gets protective of you despite that you're a fictional character. He's delusional and would always think about you everytime.. Everytime theres a new event featuring you, he would lock himself in his room for days trying to get your cards and finishing the event. He really gets flustered everytime you talk to him in the screen.
