Genre: Suspense, Action
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 at night to the streets of Ikebukuro. Masaomi warns Mikado about people he doesn’t 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 bike that occasionally neighs like a horse,
and who is rumored to have no head under her helmet. The “Black Rider” is Celty Sturluson, an Irish dullahan who is in Ikebukuro looking for her stolen head. The narrative follows all of the characters equally, showing how their lives intersect and creating a greater plot line from what each character knows about a common incident.
The story is told from the perspective of eleven or so of the main characters changing every episode in the anime. However the narrator is not always the episode’s one and only character perspective given. One of the few constants given in every episode is that the narrator gives his own opinion on the current situation that they are in, as well as certain things that make them tick and keep them going in Ikebukuro, a city with a large underbelly that is the medium for the majority of both the plot’s development and random violence throughout the series.
The heroine of the series and member of the Dollars. Also known as “The Black Biker” or “The Headless Rider”, she is a Dullahan from Ireland who came to Japan looking for her stolen head. Her motorcycle is actually a disguised headless horse called a Cóiste-Bodhar. She has no heart and perceives via unknown sensors that are not located on the head. The physical strength she possesses is above human, though not quite on par with Shizuo Heiwajima. She is also capable of manipulating a shadow-like, durable substance to form objects ranging from gloves to chariots at her will. Celty lives with Shinra Kishitani, and the two are romantically involved. She works as an underground courier. She wears a helmet when she goes out and communicates via a PDA. She enjoys online chatting, television and DVDs. She is one of the minority who knows the creator of the Dollars and that Anri is in control of Saika. Over the course of the series, her relationship with Shinra intensifies; eventually, she says that she is in love with Shinra. She has a habit of punching Shinra in the stomach whenever he talks about his love for her. She tends to get mad when Shinra says she does not need her head. Despite being a supernatural creature, she is afraid of extraterrestrials and has developed a fear of traffic officers as they started pursuing her frequently. Her biggest fear, however, is that if her head is destroyed, the same may happen to her. Unbeknownst to Celty, Izaya Orihara has possession of her head before Kasane stole it and gives it back to its rightful owner. Upon being restored afterwards, Celty became amnesic with Shinra deciding to help her regain her memories or make new ones as she attempts to readjust to life in Ikebukuro again.
