The second season of the anime adaptation "The Detective Is Already Dead" (Japanese: "Tantei wa Mō, Shindeiru.") will premiere on Wednesday, October 7, 2026, on Japanese television. The streaming service d Anime Store will start the broadcast on the same day at 10:00 PM (JST), showing the new episodes before their TV airing; TOKYO MX will take over from 10:30 PM. AT-X and BS Nittele will also be part of the initial broadcast day, with additional platforms following from Monday, October 12. The announcement coincides with the release of the third promotional video for the series, which features new footage and, for the first time, excerpts from the two theme songs of the second season.
Additionally, two new characters appear: Mia Whitlock and Scarlet. Akari Komiyama voices Mia Whitlock, who is listed as one of the so-called Tuners ("Stimmers") and is described in the announcement as a shrine maiden. Nobuhiko Okamoto voices another Tuner named Scarlet, whom the production describes as a vampire. Both characters are already shown in action in the third trailer.
The music for the new episodes is handled by singer Kōme and singer Kagura Nana: Kōme contributes the opening theme "Kono Shinzō ni Hanataba o" (roughly "A Bouquet for This Heart"), while the ending theme is Kagura Nana's "Hakuchūmu" ("Daydream"). Kagura Nana is thus active for the series again, having previously provided vocals for the first season. The theme songs were composed and written by 40mP; the series music is by 40mP and Yuuyu.
The production continues to be handled by Studio ENGI. Manabu Kurihara directs, Deko Akao is in charge of series composition and scripts, and Yōsuke Itō returns for character design. The voice cast includes Arata Nagai as Kimihiko Kimizuka, Saki Miyashita as Siesta and Noches, Ayana Taketatsu as Nagisa Natsunagi, Kanon Takao as Yui Saikawa, Saho Shirasu as Charlotte Arisaka Anderson, Mai Fuchigami as Fūbi Kase, Yumiri Hanamori as Hell, Maria Naganawa as Alicia, and Yoshitsugu Matsuoka as Kōmori.
The story follows high school student Kimihiko Kimizuka, who, after the death of the brilliant detective Siesta, whose assistant he once was, initially returns to a quiet everyday life – until an encounter with Nagisa Natsunagi entangles him once again in the events surrounding Siesta's death and the mystery of her legacy.
Before the series premiere, the team has announced several accompanying programs: AT-X will repeat all twelve episodes of the first season in a marathon on October 3, and advance screenings of the first two new episodes with a talk session featuring the voice cast are planned. Additionally, a stage appearance is scheduled as part of the Kyoto International Manga Anime Fair.
The second season has a long announcement history: After the first season, which started in July 2021 with twelve episodes, the continuation was officially announced as early as July 2022. It was originally slated to start in July 2026 but was then postponed to autumn due to production reasons.
The source material is the light novel series by author Nigojū with illustrations by Umibōzu, which has been published under KADOKAWA's MF Bunko J imprint since November 2019 and was awarded the 15th MF Bunko J Newcomer Award. In Japan, thirteen volumes of the series are currently available. The first season of the anime adaptation was also made available internationally via streaming services.
