"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!

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...!

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!

If you see Shizuo Heiwajima, don't wait around. Run!! Mikado is an average high-schooler whose life has been anything but since moving to Ikebukuro! After coming face to-neck?-with the legendary "Headless Rider," Mikado can hardly wait to encounter more of the city's peculiar residents. But when Mikado is caught in the middle of a feud between Izaya Orihara and Shizuo Heiwajima, he soon realizes that Ikebukuro's most unbelievable characters are also among its most dangerous...

It’s ok to be a monster. ​Although the Dollars are long gone, the city is far from quiet. In Ikebukuro, anyone who expresses an interest in the Headless Rider mysteriously vanishes. At Raira Academy, Yahiro Mizuchi and Kuon Kotonami have begun tracking some of these disappearances for their classmate Himeka Tatsugami, whose sisters are among the missing. But nothing could prepare them for who they encounter during their search—none other than Celty Sturluson, the Headless Rider herself!

I want to see Shizuo. Soon, soon, soon... A mysterious serial slasher has struck in Ikebukuro. The username "Saika" appears in online chat rooms in sync with the attacks. Saika-the name of the demon blade that appeared in Shinjuku years and years ago... In its chat room posts, Saika repeats one name over and over again, as though singing the praises of its beloved: Shizuo Heiwajima, Shizuo, Shizuo...
