The Detective is Already Dead will start airing on July 4, 2021, with a 1-hour long special first episode. A new PV for the upcoming anime has also been released.
Studio ENGI (So, I’m a Spider, So What?) is producing The Detective is Already Dead anime. Manabu Kurihara is directing, with Yousuke Ito on character designs. Deko Akao is taking care of series composition. The anime is based on a light novel by Nigozyu.
Shin Nagai is voicing Kimihiko Kimizuka, while Saki Miyashita voices Siesta. Additionally, Maria Naganawa, Takehito Koyasu, Saho Shirasu, and Yoshitsugu Matsuoka are also starring in the anime.
Yen Press, the English publisher for the light novel, describes the plot as:
“You will be my assistant.” During a plane hijacking four years ago, Kimitsuka Kimihiko wound up becoming the assistant to a beautiful detective named Siesta. The pair traveled the world, solving crimes and battling criminal organizations. Until Siesta died, anyway. Kimitsuka thought that would spell the end of his adventures and a return to ordinary life, but an encounter with a girl who bears an uncanny resemblance to Siesta suggests that fate has other plans.
Kagura Nana, popular Vtuber, is preforming the ending theme for the anime, which is titled “Koudo” (Altitude).
