Kitano Seichiro - a boy with a face of a demon, but the heart of an angel. The story begins with him attending a new school, where nobody knows him... Because of his appearance, teachers and fellow classmen think he is the worst delinquent, "violence incarnate". They try to correct him, expel him or beat him up. Lots of accidents doesn't help to fix the situation either, and he gains the guardian position at his school. But because of his ultra-goodie attitude, some of those that attack him become his friends...All the misunderstandings make the story extremly funny.
