Durarara!! S01

In a place called Ikebukuro, a district in Tokyo where groups of street-fighting teenagers form, a series of events unfolds involving street thugs, high school students, a radio announcer, a pathologist, and a young information broker. The thugs and gangsters are terrified of an urban legend known as Dullahan, a headless rider on a black motorcycle with no light or sound. Ryuugamine Mikado is an ordinary high school student who is fascinated by the strange and bizarre, and when he arrives in Ikebukuro, he frantically searches for Dullahan's missing head.
