"I'm not doing anything. All the Dollars did that together..." The holiday isn't over yet. The day after Izaya was stabbed, the scars of the recent incident are still fresh in the city. An eccentric couple wanders the town together as a sister keeps an eye on the girl hanging around her brother. Two women--one a child, one an adult--pursue the meaning of strength, focusing their attention on the strongest man in town. A set of mischievous twins don't bother to care about their brother. A yakuza clings to his past. Meanwhile, an underground doctor just wants to enjoy a vacation with a recently relaxed headless dullahan... Ikebukuro is going to be busy!

In the sequel series to the urban fantasy Durarara!!, Yahiro Mizuchi has come to Tokyo in the hopes of starting a new life (and maybe seeing the Headless Rider), but the famous Dullahan hasn't been seen in half a year-and neither has anyone who's gone to find her!

Ikebukuro, Tokyo. All kinds of people are showing up to settle their scores with Izaya Orihara the information broker. A pair of foreigners who specialize in odd jobs. A runaway girl still looking for her Shizuo. A fellow dressed like a bartender who looks like he's had better days. A womanizer set on getting his revenge against the Dollars. An underground doctor waiting for someone to come home. A class representative with a clueless classmate pal and a target on his back. And a headless rider who can't help getting sucked into trouble. Question is, is this spring break something special, or is this just business as usual in Ikebukuro?

"Do you enjoy being the Black Rider who's been spotted all over Ikebukuro over the past few years now? Why is it that you're riding such a dangerous bike all over the place? Are you aware that you're violating the law?!" Ikebukuro, Tokyo. A place full of fires waiting to be lit and plenty of people ready to light a match: Twins who are the perfect opposite of each other. An idol who's nothing like her older brother. A girl with a crush on her senior in the Dollars. And a headless rider with a bounty on her...uh, head. Keeping the peace is probably not gonna happen.

After being framed by Izaya and forced to become fugitive on the run, Shizuo. Forced to rethink his position and circumstances, Mikado. Only now realizing the predicaments of his friends, Masaomi. Unaware of everything going on as she flees her house, Anri. Events going far beyond anything she could have imagined, Akane. Unable to conceal her excitement at coming into contact with the Black Rider, a girl. Continuing to wait anxiously at home, Shinra. Scheming so everything goes his way, Aoba. Working towards enacting his revenge on the Dollars, Chikage. And lastly, the person who will save the Headless Rider is--Ikebukuro is warping again today in the next installment of Durarara!!

A twisted love for humanity... Izaya Orihara is used to getting his hands dirty, manipulating others for his so-called "love." While working with the Awakusu-kai to locate a group distributing drugs, the information broker finds himself trapped in a dark room with a burlap sack over his head. As with all things Izaya, on of several reasons for his current predicament can be traced to his youth. Meanwhile, Shinra opens up to Celty about his time in middle school with Izaya and the boy's connection to his car. Through all the chaos, does Izaya have everything under control in Ikebukuro?

Ikebukuro has a slashing problem. Ikebukuro, Tokyo. A place where the clumsy and inept at love gather. A high school girl worried about her status. A third-rate magazine reporter covering the Ikebukuro beat. A teacher suspected of sexual harassment. A thug wearing a yellow bandanna, who is said to be the toughest around. A young man who deals in all manner of sensitive information. And a headless rider on a coal-black motorcycle. As these individuals and more are drawn into a whirl of unlucky incidents, Ikebukuro itself will begin to crumble...!
