The story takes place in Ikebukuro, a district of Tokyo. Teenage punks
gang up and fight against each other. The gangsters are afraid of an
urban legend called "Dullahan", a headless rider, who rides a black
motorcycle without head lights or engine sounds. Ryuugamine Mikado is a normal high school boy who seeks peculiar beings. When he moves in to Ikebukuro, a mad scramble for Dullahan's missing head breaks out.
