デュラララ!!

Hoping for something out of the ordinary, Mikado Ryuugamine moves to Tokyo's Ikebukuro district at a childhood friend's invitation and walks straight into the neighborhood's strangest residents. Among them is Celty Sturluson, an Irish dullahan who works as an underworld courier while riding a silent black motorcycle in search of her stolen head. As rumors swirl about an anonymous street gang called the Dollars, Mikado's quiet new life tangles with Ikebukuro's most dangerous people.
