Demon Slayer fans are buzzing with excitement after online rumors suggest that the series’ highly anticipated story arc will be adapted into a three-part cinematic event.

The speculation about a Demon Slayer Infinity Castle trilogy gained traction when a Weibo account, known for leaking anime news, hinted at an upcoming major announcement.

Ufotable has yet to make an announcement about the rumored Demon Slayer movie. The Japanese studio’s most recent confirmation was on June 19, when they announced that Demon Slayer’s next release would be Season 4’s Hashira Training arc. These events take place before the Infinity Castle arc.

Ufotable has yet to confirm a release date for Season 4, but the series is expected to return in Spring 2024. But, it’s more likely that the Hashira Training arc will premiere in Fall 2024.

Readers of Koyoharu Gotouge’s Kimetsu No Yaiba manga deem the Infinity Castle arc as a pivotal juncture in the series. 

Within this arc, crucial confrontations between the primary protagonists and antagonists transpire, and bringing these intense clashes to the big screen can propel Demon Slayer to shatter box office records once again.

Despite being released at the height of the COVID-19 pandemic in 2020, the Demon Slayer Mugen Train movie broke records and became the highest-grossing Japanese film of all time, with more than US$507 million in earnings. 

In fact, it beat Spirited Away’s 19-year record after grossing US$223 million just over two months after its release. The film received high praise for its gorgeous visuals and top-tier animation, particularly in its enthralling fight scenes.

The Mugen Train movie only featured two significant clashes between the Demon Slayer Corp and Muzan Kibutsuji’s Twelve Demon Moons.

The Infinity Castle arc, in comparison, will have way more confrontations between the strongest members of the Demon Slayer Corp and Muzan’s top-ranked demons. This also means there will be more over-the-top battles between the Hashira and the Upper Moons.

The Infinity Castle arc covers 47 chapters that delve into significant character development for well-known figures in the series. Additionally, numerous secrets will be revealed at the end of the arc.
