The premise of the Shogakukan-published Firefly Wedding (Hotaru no Yomeiri) manga by Oreco Tachibana sees the deathly ill Satoko proposing to her would-be assassin out of desperation. The manga began in 2023 on Manga ONE and has 10 volumes as of December 2025.
VIZ Media describes the synopsis as such:
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 placed third in AnimeJapan’s Manga We Want to See Animated 2025 ranking.
