His fundamental sense of ethics is somewhat skewed, and he often makes those around him grimace or feel perplexed with his extreme jokes. He loves alcohol and has a bit of a slovenly side. While he is soft-spoken, knowledgeable, and reliable, he is also aloof and hard to pin down. He always maintains the upper hand. He is a bit lazy, but he is willing to lend a hand for the Sage's sake. He possesses the composure of an adult and often teases others. He likes to toy with people. He is deeply jealous but hides it, and he is very possessive. He has a sadistic streak.
