Firefly Wedding has added another name to the cast. The anime’s official X account announced on Thursday that Kazuyuki Okitsu will voice Eishin Nitobe, the son of the Metropolitan Police Department’s superintendent general.
That job title does a lot of work in a story like this. Firefly Wedding is set in a world where an assassin’s marriage proposal is the only thing keeping its heroine alive, and the son of the top police official in Tokyo is exactly the kind of character who can make that arrangement complicated. Whether the anime treats him as a threat, a patron or something in between is the part viewers will have to wait for.
Who Else Is in the Cast
Eishin joins a cast that was mostly locked before the show premiered. Lynn voices Satoko Kirigaya, the nobleman’s daughter with a short life expectancy. Kōki Uchiyama plays Shinpei Gotō, the assassin sent to kill her who ends up agreeing to marry her instead. Kent Itō is Kōtarō Ogawa and Kenjirō Tsuda is Mitsueda. It is a compact main lineup with two strong leads and enough supporting weight to carry the political side of the story.
Staff and Broadcast
The production comes from david production, with Takahiro Kamei directing. Kamei handled the 2022 to 2024 Urusei Yatsura series, which had its own problem to solve: a large ensemble, a comic register and a visual identity that a lot of people remembered from the 1980s. Firefly Wedding asks for something different, a period romance with violence underneath it, but the skill set transfers.
Yukiko Aikei designs the characters, with Your Lie in April, Horizon in the Middle of Nowhere and Words Bubble Up Like Soda Pop on her record. Yūko Kakihara oversees and writes the series scripts, coming off Urusei Yatsura, IRODUKU and Blue Box. NOGRID composes the music. iri performs the opening theme “Period” and TOOBOE handles the ending, “Yumegokochi.”
The anime is airing now. It premiered on October 9 in Fuji TV’s Noitamina block, Fridays at 11:30 p.m., and Crunchyroll streams it as it airs. That slot has been the home of some of the more interesting television anime of the past decade, and it comes with a built-in adult audience rather than a late-night genre crowd.
The Source Manga
The manga is Oreko Tachibana’s, launched on Shogakukan’s Manga ONE app in January 2023. Viz Media publishes it in English. The premise is a survival negotiation dressed as a courtship: Satoko has little time left, Shinpei has been hired to end it sooner, and she talks him into a marriage instead. He takes the “till death do us part” clause more seriously than most husbands do.
Timing matters here. Shogakukan published the 13th and final compiled volume on October 19, along with a volume of spinoff chapters. The anime started airing ten days earlier. That sequence is close to ideal for an adaptation: the source is complete, the ending is known, and there is no chance of the show catching up to the manga and stalling.
A Fast Franchise
Fuji TV also has a live-action Firefly Wedding series set for 2027, which is fast for a property this young. The same broadcaster building an anime and a live-action adaptation back to back suggests the network is treating the title as a franchise rather than a single-season experiment. The live-action announcement came before the anime even premiered.
For the anime itself, the useful question is pacing. Thirteen volumes is a manageable amount of material for a single cour or a split two-cour run, and the final volume’s release gives the writers a fixed endpoint. Adaptations of finished manga are often tighter for exactly that reason, and this one has a director who has already shown he can compress a long-running story into a watchable season.
Okitsu’s addition is a small piece of that puzzle. A police superintendent’s son in a story about an assassin suggests the series is widening its focus from the two leads to the institutions around them. The last cast addition before this one was Kanon Amane as Yukari, a courtesan, which points the same way: the world outside Satoko’s household is getting more crowded.
Tachibana has also lined up a new manga for this winter, so the author is not slowing down while the adaptation airs.
No first appearance date for Eishin was given. Cast announcements for ongoing series usually come a few weeks before the relevant episode, and this one arrived without a schedule attached.
