From Yen Press:

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?

From Yen Press:

Ikebukuro, Tokyo—a neighborhood where twisted love prowls!! A series of street slashings in Ikebukuro begins to connect total strangers:

A teenage girl with no personality of her own; a beat writer for a third-rate tabloid; a teacher suspected of harassment; an informant based in Shinjuku…and a headless rider straddling a pitch-black motorcycle!! Meanwhile, the slasher continues to terrorize the night, all in search of…“him”!?

The characters of Durarara!! have been made small and are going on a rampage in Ikebukuro! Lots of things are happening today on these streets where reality and illusion mix together!
