An assassin with an obsessive heart, a dying noblewoman with nothing left to lose, and a marriage proposal that was never supposed to be sincere — Firefly Wedding (ホタルの嫁入り, Hotaru no Yomeiri) is heading to TV screens on 9 October 2026, and Singapore fans can stream it day-one on Crunchyroll.
The Story: A Killer Who Loves Too Hard
Based on the completed manga by Oreco Tachibana, serialised on Shogakukan’s Ura Sunday website from January 2023 to January 2026, Firefly Wedding is a six-volume dark romance set in Meiji-era Japan. VIZ Media publishes the English edition digitally, so the full source material is already accessible to readers here.
The premise is deceptively simple: Satoko Kirigaya has everything a Meiji noblewoman could want on the surface — wealth, beauty, a name that commands respect. What she keeps hidden is a failing heart and a clock that is running out. When an emotionless assassin named Shinpei Goto is sent to kill her, Satoko makes the only play she has left: she asks him to marry her.
It is not a sincere proposal. But the manga’s tagline says it plainly in Japanese — 「俺、ちょっと愛が重いけど幸せにするよ」 — something along the lines of: “My love might be a little heavy, but I will make you happy.” Shinpei, it turns out, loves with the same intensity he kills.
David Production at the Helm
The adaptation sits in capable hands. David Production — the studio that brought JoJo’s Bizarre Adventure to life across multiple acclaimed seasons — is handling animation. Directing is Takahiro Kamei, best known for the warmly received 2022 Urusei Yatsura remake; series composition falls to Yuko Kakihara (Cells at Work!); and Yukiko Aikei, character designer on Your Lie in April, translates Tachibana’s style to animation.
Music is by NOGRID, with the ending theme, “Yumegokochi”, performed by TOOBOE.
Voice Cast
Lynn voices Satoko Kirigaya — she is known to Singapore anime fans from Black Clover and No Game No Life, among others. Opposite her is Kōki Uchiyama as Shinpei, whose range spans everything from Boku no Hero Academia to the Sword Art Online franchise. Supporting cast includes Kent Itō as Kōtarō Ogawa and the always-distinctive Kenjirō Tsuda as Mitsueda.
When and Where to Watch in Singapore
Firefly Wedding premieres in Japan on 9 October 2026 on Fuji TV’s Noitamina block — a programming slot with a strong track record for character-driven drama, having previously hosted Natsume’s Book of Friends, Anohana, and Vinland Saga. Crunchyroll will simulcast new episodes globally as they air, which means Singapore viewers can watch without delays or a VPN.
If you want to get ahead of the story, VIZ Media’s English digital release and Comikey both carry the full six-volume manga series now. It is a quick read, and the completed story means you can go in knowing the entire arc — which only makes the animation choices more interesting to watch unfold.
