A defiant and strong willed boy with a "I could care less" attitude.
Although at first he may appear quiet and composed, Yusuke is easily angered and not level headed. He has a hard time expressing his feeling and is an introvert and can let his emotions get the best of him. His way of expressing fondness of a person usually involves being rude to them, however he is down to earth and loyal when he becomes accustomed to you. Due to his rebel personality he has no friends of any sort and joined the host club, half because he wanted to make new friends and half because of his interest in Haruhi.
Yusuke's parents are divorced and he lives with his father who is a private investigator. He loves to surf, it is his favorite activity and he is also very close to his father. He had met Haruhi Fujioka once before he came to Ouran academy and, although she doesn't remember him, he knows about her cross dressing and has even begun to develop a crush on her, even if her hasn't admitted to himself yet.
