Infinity Castle’ Trailer Locks In For the End

Shonen fans have had eyes on Demon Slayer: Kimetsu No Yaiba since it dropped in 2019, and it’s making its way back to the big screen. Sony and Crunchyroll released the first trailer for the series’ upcoming Infinity Castle movie, which will be the first in a trilogy that’s rtaking big steps toward wrapping things up.

Based on the manga’s arc of the same name (which spans Chapters 140-183) and picking up after the end of season four, the members of the Slayer Corps have been transported into the titular castle, a massive pocket dimension that’s also the lair of demon lord Muzan Kibutsuji. To bring down Muzan, Tanjiro and his fellow Corps members will have to carve through the Castle’s horde of demons, which also include Muzan’s Kizuki lieutenants. One way or another, Tanjiro is determined to reach Muzan and kill him so he can finally cure his sister Nezuko.

Infinity Castle follows suit from 2020’s Demon Slayer: Kimetsu No Yaiba – The Movie: Mugen Train, in that it’s an actual film rather than a compilation of previous anime episodes. Mugen earned $507 million worldwide, turning it into the highest-grossing Japanese film ever, and propelled the anime into massive popularity. Infinity is the series’ penultimate arc, and at the moment, Ufotable’s keeping focus solely on this one movie: it hasn’t mentioned anything about the second and third installments, or if it’ll also adapt the “Sunrise Countdown” arc into film once this trilogy is done.

Demon Slayer: Kimetsu No Yaiba – The Movie: Infinity Castle hits theaters on September 12.

It’s time to have some fun 🔥
