Demon Slayer's New Biggest Challenger Is Officially Here

On July 18, 2025, Japan saw the release of what would end up becoming the biggest global anime movie of all time in Demon Slayer: Infinity Castle Part 1. This movie is quite easily one of the biggest hits of all time and one that changed the anime industry for good. In 2026, the Demon Slayer franchise has stayed quiet, and there doesn't appear to be any competitor that can rival or mimic what it did with the release of Infinity Castle Part 1. That said, other big, exciting projects are being lined up for 2027 that are sure to rival Demon Slayer: Infinity Castle Part 1 and Part 2, as well as potentially even challenge it. The biggest of them all is One Piece Film: God Valley.
