Durarara!!

Durarara!! often shortened to DRRR!!, is a Japanese light novel series. Mikado Ryūgamine, a young boy who longs for the exciting life of the big city, moves to Ikebukuro to attend Raira Academy with his childhood friend Masaomi Kida, whom he has not seen since he was young. After the two meet at the train station, they set out to explore the streets of Ikebukuro. Masaomi warns Mikado about people he does not want to cross in the city such as the violent and superhumanly strong man Shizuo Heiwajima, the information broker Izaya Orihara, and the mysterious gang known as "The Dollars." After running into some of the side characters, Mikado sees a local legend called the "Black Rider" who rides around Ikebukuro on a black motorcycle that occasionally neighs like a horse and who is rumored to have no head under her helmet. The "Black Rider's" real name is Celty Sturluson; she is an Irish dullahan who is in Ikebukuro looking for her stolen head while working as an underworld courier. The narrative follows all of the characters equally, showing how their lives intersect and create a greater plot line from each character's knowledge about a common incident.
