Leon is an extremely cheerful fellow who is rarely encountered being sad or depressed. The demon enjoy being around happy people in general and therefore often tries to perk up his friends if he believes them to be upset in any way. His good moods often originate from his ability to simply ignore negative aspects of his situations completely, leaving him appear naive and stupid to many people. In general he acts childish. However, Leon is not entirely dumb, he just doesn't think his actions through entirely. Especially consequences are left out by his thinking process. He has a hard time finding solutions to problems if his first ideas do not work out. Leon prefers simple logics and therefore devaluates everything that he doesn't understand entirely as "too complicated". Anything in relation to science is often called that by him.
