Firefly Wedding Anime Coming in 2026

Fans of Oreco Tachibana’s hit manga Firefly Wedding have a major date to mark on their calendars. The series is officially getting an anime adaptation set to premiere on October 9, 2026. This brings the intense and moody story of Satoko and Shinpei to television for the first time.

The story follows Satoko Kirigaya, a young noblewoman who suffers from a terminal heart condition. Her life takes a wild turn when she finds herself targeted by a professional assassin. Instead of giving up, she makes a bold and desperate marriage proposal to the killer, Shinpei Goto. It is a twisted start to a relationship built on survival.

This adaptation is exciting news for readers who love high stakes drama and dark romance. Seeing these characters in motion should add a new layer of tension to their dangerous situation. We are looking forward to seeing how the studio handles the unique tone of the original manga when it arrives in late 2026.
