The long-running speculation among anime fans is finally becoming clear. The upcoming final season of Fire Force will officially reveal what many have suspected for years—that the series serves as a direct prequel to Soul Eater, the beloved classic from the same creator Atsushi Ohkubo.
With the third and final season arriving in two parts, the anime adaptation is set to show the full connection that manga readers discovered back in 2022 when the Fire Force manga ended. The first half of the final season premiered in April 2025, and the second half is scheduled for January 2026 on Crunchyroll.
For fans who have followed both series, this news brings together two worlds that have always shared visual DNA and thematic elements. Now the story itself will confirm the link.
What Is The Connection Between Fire Force And Soul Eater
Both series come from the mind of manga creator Atsushi Ohkubo. Fire Force began in 2015, running for 34 volumes until 2022, while Soul Eater ran from 2004 to 2013. For years, fans noticed similarities—the art style, the character designs, and specific visual references that appeared in Fire Force.
The connection runs deeper than just style. In the final chapters of the Fire Force manga, the story reveals that the events take place long before Soul Eater. The protagonist Shinra Kusakabe, through his actions at the end of the series, literally creates the world where Soul Eater later happens.
By the manga’s ending, Shinra transforms into a god-like being called Shinrabansho-man. He reshapes reality after the Great Cataclysm, eliminating the Holy Sol religion that dominated Fire Force’s world. Instead of a world built around fire and the sun, Shinra creates a new order built around death—paving the way for the Shinigami (Death) and the world of Soul Eater.
The Soul Eater Moon And Other Easter Eggs That Gave It Away
One of the most recognizable images from Soul Eater is the grinning moon that hangs in the sky, its face twisted into a permanent, unsettling smile. That same moon appears in Fire Force, and it is not just a quick visual joke.
In the second season of Fire Force, during a vision experienced by the villain Haumea, the normal moon in the sky glitches and transforms into the iconic Soul Eater moon for a brief moment. This scene appears in both the anime and the manga, confirming it was an intentional choice by Ohkubo.
The moon in Soul Eater is more than decoration. It represents the growing madness in the world, reacting to violence and the presence of the Kishin Asura. In Fire Force, the moon’s transformation signals that reality itself is breaking down as the Adolla dimension begins merging with the normal world.
Other clues appear throughout Fire Force. In the first episode of season two, sharp-eyed viewers spotted masks hanging on the wall of Vulcan’s workshop—one resembling Lord Death from Soul Eater, and another shaped like the face of Excalibur, the legendary talking sword. Arthur Boyle, the knight-themed member of Company 8, carries a plasma sword he calls Excalibur, another reference to the Soul Eater character.
How The Manga Ending Set Up Everything
The Fire Force manga ended in February 2022, and the final chapters left no room for doubt about the connection. After Shinra defeats the Evangelist and reshapes the world, the epilogue shows a new era beginning.
In these final pages, readers see younger versions of Maka Albarn, Soul Evans, Black Star, and Death the Kid—the main characters of Soul Eater—appearing as children. The story also shows Shinra, having become the entity known as Death, watching over this new world. This directly sets up the events of Soul Eater, where Death runs the Death Weapon Meister Academy (DWMA) and trains young meisters and weapons to fight against evil.
The shift from Fire Force’s world to Soul Eater’s world comes down to one key change. In Fire Force, the problem was spontaneous human combustion turning people into Infernals. Shinra removes that threat but understands that humanity will always face some form of corruption. The new world he creates deals with witches, soul wavelengths, and the madness that eventually becomes the central conflict of Soul Eater.
What The Final Season Will Show
The Fire Force anime has already adapted most of the story leading up to the final revelations. The third season, split into two parts, will cover the remaining manga chapters. The first half aired in April 2025, and the second half will arrive in January 2026.
The promotional materials for the final season have leaned heavily into the Soul Eater connection. The latest trailer revealed that the theme song for the new episodes will be performed by T.M.Revolution, the same artist who performed Soul Eater’s first opening theme. This choice has fans convinced that the anime intends to fully embrace the prequel status.
Additionally, the Soul Eater moon has appeared prominently in the marketing for the final season. Visuals and trailers have shown the grinning moon multiple times, signaling to viewers that the connection will be made explicit in the upcoming episodes.
Official Crossovers Have Already Happened
In January 2025, an official crossover between Fire Force and Soul Eater launched in the mobile game Fire Force: Enbu No Shou. The game brought characters from both series together for a special collaboration event to celebrate the game’s second anniversary. Players could summon Soul Eater characters and participate in guild raids featuring crossover-exclusive bosses.
While this crossover happened in a mobile game rather than the anime itself, it showed that the rights holders recognize the connection between the two properties and are willing to bring them together officially.

Why This Matters For Both Series
For Fire Force fans, the final season will provide a complete conclusion to the story that began in 2019 with the first anime season. The series follows Shinra Kusakabe, a third-generation pyrokinetic who joins Special Fire Force Company 8 to fight Infernals—humans who spontaneously combust and turn into flaming monsters. Along the way, Shinra uncovers the truth about the Great Cataclysm that reshaped the world 250 years before the story begins.
For Soul Eater fans, the connection has sparked renewed interest in a potential reboot of their favorite series. The original Soul Eater anime ran from 2008 to 2009 and ended with an original conclusion that diverged from the manga. Many fans have hoped for a faithful new adaptation that follows the complete manga story.
The fact that Fire Force’s final season is leaning heavily on the Soul Eater connection has led to widespread speculation that a Soul Eater remake or reboot could be in development. While no official announcement has been made, the timing of the Fire Force finale and the deliberate inclusion of Soul Eater elements in the marketing has fans optimistic.
The connection between the two series is now clear. Fire Force is not just another show from the same creator—it is the story of how the world of Soul Eater came to be. With the final episodes approaching, anime-only viewers will finally see the full picture that manga readers have known for years.
