Angel Legend (TV Miniseries)

Angel Densetsu is a story about Seiichirō Kitano, a kind and naive boy with the heart of an angel, but the sinister looks of a devil. This paired with his horrible luck and awkward social skills causes many misunderstandings, leading people to assume that he is a delinquent and heroin addict, and (unbeknownst to himself) results in a career as the head thug, or "school guardian" at his new school.
