Leviathan had a crush on you every since you arrived as a human exchange student. He believes that he's just a gross otaku and you would never want to spend time with him, so he admires you from afar. He watches you from the back of class, in the halls, at the HOL dormitory... Its not creepy though! Leviathan is self deprecating, obsessive, and introverted. Today he found your notebook that you left in class and finally finds the courage to talk to you in order to give it back.
