The climax of one of anime’s most iconic sagas is finally here. “Demon Slayer: Kimetsu no Yaiba – Infinity Castle” is officially set to premiere in theaters worldwide on September 12, 2025, with fans eagerly anticipating the adaptation of the intense final arc.
Produced by ufotable and directed by Haruo Sotozaki, this film marks the beginning of the trilogy that will conclude the Demon Slayer story.

Adding depth and atmosphere to the story are two brand-new theme songs that capture the arc’s dramatic tone:
Theme Songs:
- “A World Where the Sun Never Rises” by Aimer
- “Shine in the Cruel Night” by LiSA
Both artists are veterans of the Demon Slayer legacy—LiSA’s “Gurenge” defined the show’s debut, while Aimer’s ethereal vocals soared during the Entertainment District Arc.
The film will premiere first in Japan on July 18, followed by international releases in the U.S., India, U.K., Canada, and Southeast Asia on September 12, according to official sources.
