Demon Slayer: Infinity Castle Arc Release Date Leaked – Here’s Everything We Know!

The much-anticipated Demon Slayer: Infinity Castle Movie has sparked excitement among fans after potential release date leaks surfaced online. The film is rumored to premiere in Fall 2025, continuing the epic saga following the "Hashira Training" arc and addressing the dramatic cliffhanger from the anime’s previous season.

The Leaked Release Date

According to a listing from German CineStar, a prominent cinema chain, an "Untitled Crunchyroll/Sony/Aniplex Event Film" has been described as the Kimetsu no Yaiba: Infinity Castle Arc movie. The listing indicates a September 25, 2025 release date in Germany. This revelation aligns with a previously leaked listing from Sony’s official website, which described a similar event. However, the Sony listing was quickly removed, fueling speculation about the film’s release plans. Fan communities on social media have been abuzz with discussions, eagerly piecing together clues from these leaks.

What We Know About the Movie

The Infinity Castle Movie will pick up from the events of the "Hashira Training" arc, which saw Tanjiro and the remaining Hashira preparing for their toughest battle yet. The arc sets the stage for a climactic confrontation with Muzan Kibutsuji, the Demon King, and his most powerful upper-rank demons. The Infinity Castle itself is a sprawling, otherworldly domain that serves as Muzan’s stronghold, offering a visually stunning and emotionally intense backdrop for the story’s final showdown.

The movie will likely showcase the continuation of Tanjiro Kamado’s journey, alongside the fierce and skilled Hashira. Fans anticipate high-stakes battles, emotional moments, and groundbreaking animation as the series edges closer to its finale.

Recap of Tanjiro’s Journey

For those new to the series, Crunchyroll’s official synopsis of Demon Slayer introduces Tanjiro’s quest:

“It is the Taisho Period in Japan. Tanjiro, a kindhearted boy who sells charcoal for a living, finds his family slaughtered by a demon. To make matters worse, his younger sister Nezuko, the sole survivor, has been transformed into a demon herself. Though devastated by this grim reality, Tanjiro resolves to become a ‘demon slayer’ so that he can turn his sister back into a human and kill the demon that massacred his family.”

This emotional premise drives the narrative, with Tanjiro battling demons while seeking a cure for Nezuko. The Infinity Castle Arc represents a turning point where the stakes are higher than ever, both for Tanjiro’s personal mission and for the Demon Slayer Corps.

Given the series’ track record, fans can expect unparalleled animation quality from Ufotable, the studio behind Demon Slayer. Previous films, such as Mugen Train, have set high standards, becoming global hits due to their stunning visuals and gripping storytelling. The Infinity Castle Movie promises to continue this legacy, combining emotional depth with action-packed sequences.

While the leaked date of September 25, 2025, is unconfirmed, the buzz around the Infinity Castle Movie highlights its significance in the Demon Slayer franchise. Fans worldwide eagerly await official announcements from Crunchyroll, Sony, or Aniplex to confirm the release and provide more details. Until then, the speculation continues, building anticipation for what could be one of the most memorable anime film releases in recent years.
