Warning: Contains BIG spoilers for Fire Force & Soul Eater.After years of no updates on its production, Fire Force has finally received news: Fire Force season 3 will premiere in April 2025, and the fourth and final season will air in January 2026. That means there will be a five-year gap between seasons 2 and 3, but if the quality remains consistent or improves, it will be plenty worth the wait.

The news of Fire Force season 3’s release date also came with a new trailer and key visual, and both include a major spoiler about the ending of the series. The final arc of Fire Force continues to deliver more and more shocking revelations about the true nature of its world, and surprisingly, Fire Force season 3’s trailer spoils the biggest reveal about the world and its connections to Atsushi Ohkubo’s other works.

The popular Fire Force manga was created by the same author of Soul Eater, and the connection between the two works will be revealed in Season 3. Granted, the twist isn’t explicitly detailed, but it’s still surprising that promotional material would reference such a big part of the story, regardless.

Fire Force’s Promotional Material Spoils Its Massive Soul Eater Connection

Fire Force & Soul Eater’s Connection Explained

While both the trailer for Fire Force season 3 and the key visual don’t show off much of the story, one notable feature they share is the appearance of a crescent moon with a smile on its face, the same moon that was a key part of Atsushi Ohkubo’s previous work, Soul Eater. The presence of the moon isn’t just a reference, though; as the final arc goes on, it becomes increasingly clear that the moon was the first sign that Fire Force is a prequel to Soul Eater, so its inclusion in the promotional material is a massive spoiler.

Why Is Fire Force Spoiling Its Biggest Twist?

David Production is already spoiling the major twist that Fire Force is a prequel to Atsushi Ohkubo’s Soul Eater, and it’s hard to understand why. Even if Fire Force will have been over for three years by the time season 3 premieres, there are probably a lot of people who haven’t read the manga and have exclusively been watching the anime, so David Production is spoiling Fire Force’s biggest twist for a large number of its fans and effectively ruining the series for them.

Conversely, David Production spoiling the big twist could be seen as a form of marketing on their part. With how long it’s been since both the anime and the manga ended, Fire Force is nowhere near as popular as it once was, so David Production spoiling Fire Force’s connection to Soul Eater might be to revive interest in the anime before it returns in 2025. Whatever the case, the best thing to hope for is that Fire Force season 3’s quality will make up for both the long wait time and how blatantly they decided to spoil things for people.
