Meiji era Japan. Satoko Kirigaya, a count’s daughter with a serious heart condition, proposes marriage to the assassin who was hired to kill her.
Firefly Wedding placed first in the 2024 nationwide booksellers’ recommended comics list. It also won Comic Cmoa’s 2024 Electronic Comic Award grand prize. As checked on October 19, 2026, the anime’s official site reports more than five million copies in circulation.
In Meiji-era Japan, Satoko hopes to marry into a prominent family and make her father proud. Her abduction puts that future at risk. To survive an encounter with the assassin Shinpei, she offers him marriage—a promise he takes seriously.
The official introduction describes a romantic suspense story. Satoko’s family obligations pull against her feelings, while Shinpei’s devotion comes with jealousy and violence. The mystery behind her kidnapping gives the relationship its immediate stakes.
