Alongside the visual treats, the official announcement revealed exciting new cast additions that are sure to shake up the story dynamics. If you are building your fall watchlist, this is shaping up to be a standout title alongside other major mystery anime dropping this October.
Meet Noches: A Familiar Face Enters the Fray

Perhaps the most shocking revelation from the latest update is the introduction of a brand-new character named Noches. Sporting an appearance that is virtually identical to the legendary detective Siesta, Noches is immediately enveloped in an aura of profound mystery.
Who exactly is she, and what is her true identity? Adding an incredibly meta and thrilling layer to the casting, renowned voice actress Saki Miyashita—who famously voices Siesta—will also be stepping into the role of Noches. This dual casting hints at deep narrative connections that will undoubtedly keep viewers guessing, offering the same level of suspense found in the best masterpiece anime available today.
What Is The Detective Is Already Dead?
For those new to the franchise, The Detective Is Already Dead originates from the hit light novel series written by Nigoju and illustrated by Umibozu. The story follows Kimihiko Kimizuka, a teenager who acts as a literal magnet for trouble. His life changed forever when, during a hijacking on an airplane flying 10,000 meters in the sky, he was forced to become the assistant to a brilliant, silver-haired detective named Siesta.

For three years, the duo traveled the globe, battling shadowy organizations and experiencing dizzying adventures worthy of the top battle anime of our era. But their legendary partnership ended in tragedy when Siesta passed away. A year later, as Kimizuka attempts to live a normal life, a young girl named Nagisa Natsunagi appears, claiming to need his help. This encounter forces Kimizuka back into the clandestine world of mysteries, leading him to uncover the shocking truth behind Siesta’s death and the heavy burden of inheriting a legendary detective’s legacy.
As the official synopsis brilliantly teases: “The detective is already dead. The truth of her death has also been revealed. But it is entirely too early for an epilogue.”
