Artist Perspectives on the Tie-In
Reflecting on her contribution to the series, iri shared a statement on the anime’s official website explaining her creative process. She noted that this project is her very first time writing a song specifically for an anime. She stated that she was deeply moved by the character Satoko, who stands firmly on her own two feet and faces reality head-on despite being nearly crushed by harsh truths. Because this collaboration coincides with a turning point for her, she created the song while reflecting on her current feelings.
Pixelwolf noted that the main promotional video pairs the series dangerous central relationship with the first public preview of iri’s track. The publication observed that “Period” introduces a contemporary, beat-led vocal identity to a Meiji-era story rather than relying on a conventional period-drama sound, establishing a distinct pop pulse against the narrative’s escalating tension.
Satoko Proposes Marriage to Assassin Shinpei
Viz Media outlines the premise of Firefly Wedding around Satoko Kirigaya, a noblewoman who appears to have everything—beauty and elite status—except time, as she is also quite ill and only has a short time left to live. When a mysterious assassin named Shinpei targets her, she makes a desperate marriage proposal to save her life. Shinpei accepts, taking “until death do we part” seriously.
As the series broadcasts weekly, international fans can follow the episodes on Crunchyroll while awaiting the physical release of iri’s single in November.
