For Fans of Durarara!!

There are thousands of supernatural protagonists in anime, and most of them exist to fight or to suffer. Celty is neither. She is a Dullahan who has lost her head and her memories, earns a living as a courier, and communicates entirely through a phone, and in every scene she is the most emotionally grounded person in the room. The writing trusts her interiority completely, which is a rarer thing than any action sequence.

Baccano! appeared first, but Durarara!! perfected the format: dozens of perspectives, a timeline that folds back on itself, and a climax that makes you want to reread the first episode. Narita's light novels are worth reading even if you have watched the anime, because the prose style carries jokes, asides, and character beats that the adaptation compressed. The Baccano! novels cover story arcs the anime never reached.

Both works understand that a specific urban district has its own mythology, its own internal logic, and its own hierarchy of power that exists just below the visible surface. TWEWY maps Shibuya as a contested spirit world; Durarara maps Ikebukuro as a turf war between color gangs, information brokers, and immortal hitmen. The games share the anime's love of faction politics and the feeling that every side street conceals a faction you have not met yet.

Set during American Prohibition, 91 Days has almost nothing in common with Durarara on the surface. The tone is colder, the supernatural is absent, and the episode count is short. What it shares is the patient assembly of interlocking motives across a criminal network, and a willingness to let morally ambiguous characters carry the weight without resolution. Fans of Narita's plotting will recognize the structure immediately.
