The series follows 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.
They are known as special guidance counselors, but they are actually working for the Education Committee. They are known as the "Shadowy Seven" (and "Shadowy Six" after Shirataki's retirement).
