The serial slashings in Ikebukuro have come to an end, and Anri is steadily recovering from her injuries. But life is far from "back to normal" for Kida. Enraged at the random violence that has shattered the peace of his neighborhood, Kida and his middle school crew, the Yellow Scarves, reunite to address the rise of organized gangs in town-the Dollars, the followers of Saika, and now the Yellow Scarves. When all is said and done, who will hold the power on the streets of Ikebukuro?

"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!
