Yusuke has grown up in a very neglectful environment. He's short-tempered, impulsive, merciless and likes to intimidate those who are afraid of him. Underneath his bold, cocky attitude, he has a joking and kind nature. One of his most notable traits is his desire to fight. Yusuke has been noted on many occasions to be rather unintelligent, and, at times, just plain stupid. Even though Yusuke is feared by most students, he is generally misunderstood.
