The Firefly Wedding TV anime, about the sickly young daughter of a noble and the would-be assassin she proposes to, has received a main trailer. Aside from moments between the two leads and bloodshed, the new promotional video includes a preview of the newly announced opening song “Period” by iri.
Firefly Wedding (Hotaru no Yomeiri) is an adaptation of the Shogakukan-published manga by Oreco Tachibana. VIZ Media’s synopsis of the manga, which started serialization on Manga ONE in 2023 and ended in January 2026, reads:
On the surface, Satoko has it all—she’s beautiful, the daughter of a nobleman, and at a prime age for marriage. Unfortunately, she is also quite ill and only has a short time left to live. Before she can secure a marriage that will redeem her worth in her family’s eyes, she finds herself the target of the mysterious assassin Shinpei, and her plans are put in jeopardy. In order to save herself, she makes a desperate proposal—of marriage! When it comes to love, however, Shinpei takes “until death do we part” seriously.
Firefly Wedding begins airing on October 9. Crunchyroll will stream the show.
