The Detective Is Already Dead Season 2 Adds Akari Komiyama and Nobuhiko Okamoto

The Detective Is Already Dead Season 2 added Akari Komiyama as Mia Whitlock and Nobuhiko Okamoto as Scarlet on September 4. The official anime website announced both roles alongside the third promotional video, giving the two new characters a formal place in the cast before the sequel begins its Japanese broadcast in October.

What the new casting confirms

The cast announcement identifies Mia Whitlock as one of the Tuners, with her designation given as the Shrine Maiden. Scarlet is also a Tuner, identified as the Vampire. Those are the only character descriptions supplied in the announcement, so the update establishes their identities without outlining how either figure enters the season's mystery.

The third promotional video arrived with the casting news. The official staff and cast page places Komiyama and Okamoto alongside the established ensemble, while the announcement presents a separate character image for each role. Together, the video and casting reveal form the latest stage of the sequel's promotional rollout.

The official site posted the casting notice and the third video as separate news items on the same date. The casting page supplies the actor and character pairings, while the broader site confirms the video release. Together, the updates establish that the new voices are part of the sequel rather than an earlier first season credit.

The official roster lists Arata Nagai as Kimihiko Kimizuka and Saki Miyashita as both Siesta and Noches. Ayana Taketatsu is listed as Nagisa Natsunagi, Kanon Takao as Yui Saikawa, and Saho Shirasu as Charlotte Arisaka Anderson. The roster also includes Mai Fuchigami as Fuubi Kase, Yumiri Hanamori as Hell, Maria Naganawa as Alicia, and Yoshitsugu Matsuoka as Koumori.

That lineup makes Komiyama and Okamoto the two additions highlighted in the September 4 announcement. It does not provide episode numbers for their debuts or disclose how much of the new season will involve the Shrine Maiden and Vampire designations.

Production staff and theme songs

Manabu Kurihara directs Season 2 at ENGI. Deko Akao handles series composition and scripts, while Yosuke Ito serves as character designer. The official credits also name 40mP and Yuyu for the music and Nobuyuki Abe as sound director. Nigozyu receives the original story credit, with Umibouzu credited for the original character concepts.

The next confirmed milestone is the sequel's Japanese broadcast in October. Komiyama will voice Mia Whitlock, the Shrine Maiden, and Okamoto will voice Scarlet, the Vampire, with both casting choices announced alongside the third promotional video.
