The TV anime adaptation of Oreco Tachibana's manga, Firefly Wedding (Hotaru no Yomeiri), is officially set to premiere this October. The series will air during Fuji TV's prestigious Noitamina programming block, a slot known for high-profile and unique titles. The premiere window was confirmed Monday alongside the release of a new teaser visual and initial production staff announcements.
david production, the studio behind Jojo's Bizarre Adventure, is handling animation duties for the project. Takahiro Kamei, who recently directed the 2022 Urusei Yatsura reboot, is directing the series. Character designs are being managed by Yukiko Aikei, known for her work on titles such as Your Lie in April and Words Bubble Up Like Soda Pop.
Fan interest in the adaptation has been significant. Firefly Wedding secured the third spot in AnimeJapan's Manga We Want to See Animated 2025 poll, highlighting strong anticipation from the community.
The core narrative centers on Satoko, a noblewoman who possesses both status and beauty but is facing a terminal illness with little time remaining. Her initial goal is to secure a respectable marriage to protect her family's honor, but her plans are immediately complicated when she becomes the target of a mysterious assassin named Shinpei. In a desperate move, Satoko proposes marriage to him.

What begins as a transactional arrangement for survival quickly deepens, though Shinpei appears to interpret his wedding vows with extreme literalness.
Tachibana’s manga began serialization in January 2023 across Shogakukan’s Ura Sunday website and the MangaONE app. The series has reached ten collected volumes and entered its concluding arc as of late 2025.
English language readers can follow the source material through VIZ Media, which handles physical releases, and Comikey, which offers digital chapters.
