Durarara!! RE;Dollars-hen

Six months have passed since the violent upheaval that once shook Ikebukuro to its core. Now, a fragile tranquility has settled over the city, allowing its residents to resume their daily routines as if nothing ever happened. High school students revel in the carefree days of their youth, while Ikebukuro’s most formidable and dangerous fighter quietly goes about his work. Beneath this calm surface, the city's notorious informant quietly devises his next intricate scheme, and the legendary headless rider continues her nocturnal journeys through the streets, perpetually chased by pursuing officers under the cover of darkness. Yet this hard-won peace is destined to shatter. The ordinary rhythm of life in Ikebukuro will soon be violently interrupted by forces far beyond the norm. Slowly but inevitably, an unseen and mysterious threat begins to take hold of the district, tightening its grip on the city from the shadows. As tensions rise and familiar faces are drawn back into the fray, Ikebukuro stands on the precipice of an entirely new storm—one that threatens to consume everything they have fought to protect.
