"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!

Love and hate are two sides of the same coin. A year and a half has passed since the end of the Dollars, and now a series of assaults has the streets in a frenzy. The culprit? Someone cosplaying a character from an anime set in Ikebukuro! Meanwhile, Yahiro’s group has started solving local squabbles under the moniker “Snake Hands.” Their latest clients are Yumasaki and Karisawa, who want them to find the costumed assailant. This string of incidents also reminds the Headless Rider of the terror wrought by a certain slasher not too long ago… When people become consumed by their own obsessions, are extreme fans and extreme haters really all that different? Ikebukuro is about to find out!

The trio that hopes to be together again couldn’t be further apart. When Ikebukuro’s underground is set on a collision course, no one is safe. Dollars co-founder, Mikado Ryuugamine, continues his lonely struggle to purge his group of undesirables. Former Yellow Scarves leader, Masaomi Kida, returns to the city to make amends for his past. The owner of the curse blade, Saika, Anri Sonohara, seeks the truth from the two boys who keep leaving her in the dark. The three of them used to be the most important parts of one another’s lives, but now their secrets keep them separated. With a certain information broker whispering in Mikado’s ear, will their friendship survive the color gangs’ struggles? Ikebukuro is going to be busy!”

Kaito Sena's life hasn't exactly been easy. Unfortunately for him, death isn't about to get any better. Summoned by none other than Elisabeth Le Fanu, the "Torture Princess," Kaito has to choose what he wants for his second life-be her butler, or die a long, painful death by torture. What is he to do but become her servant...and help her eliminate the fourteen ranked demons wreaking havoc in the world! See the original light novel come to life in this gritty manga adaptation!

After maneuvering through negotiations and avoiding more horrific deaths, Subaru is ready to bring the fight to the White Whale! But will it really all go according to plan when nothing else has?

As schemes and plots continue to plague Ikebukuro, the Dollars are still going missing-and all ending up in one place. On the other hand, as Anri watches over the unconscious Kadota, a certain information broker arrives. And what he has to say is troubling...
