Firefly Wedding Anime Premieres on Fuji TV and Crunchyroll

The Firefly Wedding anime has officially arrived. The television adaptation of Oreco Tachibana's Meiji-period romantic thriller premiered October 9, 2026, on Fuji TV's Noitamina programming block, with Crunchyroll simulcasting the series worldwide as it airs in Japan. It is david production's first major new series since Fire Force wrapped its run, and it lands as one of the prestige titles of the Fall 2026 season.

Set in Japan's Meiji era, Firefly Wedding centers on Satoko Kirigaya, the beautiful daughter of a nobleman whose serious heart condition leaves her with very little time to live. Determined to secure a marriage that redeems her worth in her family's eyes before she dies, Satoko's plans are shattered when she becomes the target of Shinpei Goto, an assassin sent to kill her. In a desperate bid to survive, she makes a proposal of her own: marriage. Her offer is a lie, but Shinpei takes it seriously, and his devotion quickly becomes as dangerous as his profession. "Satoko Kirigaya has everything a noblewoman could want — except time," as Crunchyroll's synopsis puts it, according to Animation Magazine's fall lineup coverage. Viz Media's English synopsis of the manga adds the series' defining twist: when it comes to love, Shinpei takes "until death do we part" seriously.

The cast and staff behind Firefly Wedding

Lynn voices Satoko Kirigaya and Kōki Uchiyama voices Shinpei Goto, with Kent Itō as Kōtarō Ogawa and Kenjirō Tsuda as Mitsueda rounding out the main cast, as reported by Anime News Network. The supporting cast gives the adaptation serious dramatic weight: Tsuda is a veteran of heavyweight roles across Jujutsu Kaisen and Fire Force, while Uchiyama brings his signature intensity to an assassin who loves as fiercely as he kills.

Takahiro Kamei, who directed the 2022 reboot of Urusei Yatsura, directs the series at david production, the studio behind JoJo's Bizarre Adventure and Fire Force. Yukiko Aikei, whose credits include Your Lie in April and Words Bubble Up Like Soda Pop, designs the characters; Yūko Kakihara oversees and writes the series scripts; and NOGRID composes the music. The pairing is a strong one: Aikei's expressive character work has defined some of the past decade's most emotional romance anime, which fits a story where every glance carries life-or-death stakes.

Music plays a major role in the adaptation's rollout. iri performs the opening theme "Period," marking her first song written for an anime, with the single launching November 18, 2026. TOOBOE performs the ending theme "Yumegokochi" (Trance), according to Anime News Network. The main trailer previewing iri's theme dropped in September 2026, building the final wave of anticipation ahead of the October 9, 2026 premiere.

From manga page to screen: the Firefly Wedding timeline

Tachibana launched the Firefly Wedding manga on Shogakukan's Manga ONE app in January 2023, and Shogakukan has since published 12 compiled book volumes, with the 12th arriving June 19, 2026, according to Anime News Network. Viz Media publishes the manga in English, giving international readers a way to experience the source story. The manga's serialization concluded in February 2026, which means the anime arrives with a finished story behind it — a genuine advantage in an industry where adaptations routinely outrun their source material and stall into filler.

The road to the premiere followed a familiar prestige-anime playbook. The adaptation was announced for Fuji TV's Noitamina block, the late-night slot known for character-driven dramas; the main trailer and theme song reveals landed in September 2026; and Episode 1 debuted October 9, 2026, airing Fridays at 11:30 p.m. Japanese time. Episode 2 is expected October 16, 2026, keeping the series on a weekly schedule through the fall.

Where to watch Firefly Wedding

New episodes of Firefly Wedding stream on Crunchyroll on Fridays at 9:00 a.m. Pacific Time, which is 12:00 p.m. Eastern, with English subtitles and an English dub confirmed, as reported by Final Weapon. The series is expected to run at least 12 episodes, carrying it through late December. Crunchyroll is streaming the show across North America, Central America, South America, Europe, Africa, Oceania, the Middle East, the CIS region, and the Indian Subcontinent — effectively the entire global anime audience outside Japan.

Dub support is unusually broad for a new series. According to Animation Magazine, Crunchyroll's fall lineup lists Firefly Wedding with dubs in English, Latin American Spanish, Brazilian Portuguese, German, French, Castilian Spanish, Italian, Arabic, Hindi, Tamil, Telugu, and Polish — 12 languages in total. That level of day-and-date localization investment signals how strongly the streamer is betting on the series to travel beyond the core anime audience.

Why Firefly Wedding is the season's romance to watch

For romance fans, the appeal is the premise's built-in tension: this is a love story where the vow "until death do we part" is a literal threat, and where the heroine is racing both a terminal illness and an assassin's obsession. Noitamina has a track record with this kind of character-driven romance drama — the block previously hosted Your Lie in April — and david production's lush period detail gives the Meiji setting room to breathe. With the manga complete, viewers can invest in the slow burn knowing the story has an ending.

The honest counterpoint: early previews suggest the premiere belongs almost entirely to Satoko, whose vulnerability and quick thinking under pressure make her immediately compelling, while Shinpei arrives as the more one-dimensional figure — dangerous fixation first, personality second. As Anime TV's fall preview noted, there is room for future episodes to give him comparable depth, and the romance only works if both halves earn it. That is the season-long question worth watching.
