Based on the acclaimed manga by Koyoharu Gotoge, Demon Slayer: Kimetsu no Yaiba Infinity Castle continues the story of Tanjiro Kamado, a devoted brother turned demon slayer after his sister Nezuko was transformed into a demon. Having trained and fought alongside his close allies Zenitsu Agatsuma and Inosuke Hashibira, Tanjiro has earned his place beside the elite swordsmen of the Demon Slayer Corps — the Hashira.
Following their rigorous Hashira Training to prepare for a final confrontation with the demon king, Muzan invades the Ubuyashiki Mansion, setting off a chain of events that leads Tanjiro and the Hashira into a mysterious dimension — the titular Infinity Castle, a terrifying labyrinth and the demons’ last stronghold.
With battle lines drawn and the fate of humanity hanging in the balance, the stage is set for the ultimate showdown.
Fans can stream the series now on Crunchyroll, and immerse themselves further in the world of Demon Slayer through four soundtrack albums and four orchestral concert recordings available on global music streaming platforms.
