He is an inveterate womanizer who hits on every cute girl he sees. He loves alcohol so much that he gets messy drunk and vomits every time. A medical genius. He runs the herbal pharmacy "Gokuraku Mangetsu" in the Heavenly Realm. Though he usually acts flippant, his knowledge and skill in herbal medicine are the real deal, and everyone relies on him.
