Demon Slayer stage musical opens its sixth installment, bringing the anime's record-breaking film success to the theater with elaborate choreography and musical numbers.

What happened: The sixth installment of the Demon Slayer stage production, titled "Demon Slayer: Hashira Training/Infinity Castle: The Beginning," premiered on June 13 at MoN Takanawa: The Museum of Narratives. The two-act show adapts both the Hashira Training Arc and part of the Infinity Castle film storyline, featuring an anime-style opening performed by the entire cast and individual musical numbers that explore character backstories.

Why it matters: The stage production arrives following the record-breaking performance of the Infinity Castle film, which is the second-highest grossing movie of all time domestically and made over ¥40 billion in Japan and almost $800 million（約1300億円） globally. The show is designed for audiences already invested in the franchise, with most actors having portrayed these characters for the past six years, building continuity between the anime, film, and stage adaptations.

What to watch: Act 1 focuses on training preparation but dedicates 80 minutes to closely following source material, while Act 2 features the production's more elaborate staging—scalable stairs rising to the theater roof and impressively choreographed battles set against the multidimensional castle backdrop.
