Angel Densetsu
Ano: 1996
Angel Densetsu is a story about Seiichirou Kitano, a kind and naive boy with the heart of an angel, but the sinister looks of a devil. This causes many misunderstandings, leading people to assume that he is a villain or heroin addict, and results in a career as the head thug, or "school guardian" at his new school.
