Rev those engines, because the chainsaw is spinning up again. On June 19, coinciding with a milestone anniversary celebration for the franchise, animation studio MAPPA confirmed what fans have been desperate to hear: the next chapter of “Chainsaw Man,” the blood-soaked “International Assassins” arc, is officially in production. After the runaway success of the recent Reze Arc film, the devil-hunting saga is charging straight into what many manga readers consider its wildest stretch yet.
For the uninitiated, “Chainsaw Man” is the phenomenon born from Tatsuki Fujimoto’s manga, a gleefully unhinged, shockingly emotional story about Denji, a dirt-poor kid who merges with his pet chainsaw-devil Pochita to become the titular hero. It’s a series that pinballs between splatter-comedy, genuine horror, and heartbreak, often within the same scene, and MAPPA’s 2022 anime adaptation turned it into a global sensation. The manga’s cultural footprint is enormous, which is exactly why the studio chose a major anniversary event to drop this particular bombshell on the fandom. Warning: beyond this point there are spoilers for the “Chainsaw Man” manga and what the International Assassins arc has in store.
Rev those engines, because the chainsaw is spinning up again.”
The road to here ran through the movies. Rather than jumping straight into a second television season, the franchise adapted the beloved Reze arc — the tragic, romantic “Bomb Girl” storyline — as a theatrical film, and it paid off spectacularly. The Reze Arc movie was a critical and commercial hit, proving there was massive theatrical appetite for Denji’s chaos and giving MAPPA the momentum to keep the adaptation rolling. That success is precisely what greenlit the confirmation fans got at the anniversary event: the story continues, and it’s coming.
So what is the International Assassins arc, and why are longtime readers losing their minds over it? In short, word has gotten out about Denji — specifically about the priceless devil’s heart beating inside his chest — and suddenly he becomes the most wanted target on the planet. Assassins and devil hunters from around the world descend on Japan, each determined to carve that heart out of him and claim its power. It’s an escalation in every sense: bigger threats, deadlier foes, and a roster of unforgettable new characters who arrive to make Denji’s already miserable life exponentially worse.
This is the arc that introduces some of the manga’s most iconic figures, the kind of characters fans have been begging to see animated with MAPPA’s signature intensity. The storyline cranks the stakes far past anything in the first season, blending brutal action with the franchise’s trademark emotional gut-punches and pitch-black humor. If the anime team brings the same care and visual ferocity it poured into Reze, the fights alone could become instant highlights of the medium. Denji has always been an underdog getting kicked around by forces far bigger than him; here, the whole world is literally out to kill him.
The bigger picture is what makes this announcement so significant for anime as a whole. “Chainsaw Man” sits at the very top tier of modern shonen, part of the wave — alongside its MAPPA stablemates — that has pushed anime deeper into the global mainstream than ever before. Every new confirmation is a genuine cultural event, dissected across social media within minutes. The studio strategically revealing this at an anniversary celebration, rather than burying it in a routine press release, shows they understand exactly how much weight the franchise carries and how hungry the audience is for more.
There’s real trust here, too, which isn’t something to take for granted. MAPPA has occasionally weathered fan criticism over its packed production schedule and the pressure on its animators, but the quality of the Reze film went a long way toward reassuring the fandom that “Chainsaw Man” is in capable hands. Confirming the next arc is in production rather than merely “in development” signals genuine forward motion, a promise that Denji’s story will keep getting told with the ambition it deserves. Fans have watched too many beloved series stall out after a hot first season to take continuation for granted.
No firm release window came with the confirmation, and that’s the one frustrating catch — anime production takes time, and a project this ambitious won’t materialize overnight. But the essential news is the good news: the story continues, the wildest arc yet is officially being made, and the studio that delivered the goods on Reze is at the wheel. So sharpen your chainsaws and steady your nerves. Denji’s about to become the most hunted man alive, the whole world’s assassins are coming for his heart, and MAPPA just promised us front-row seats to the carnage.
What Do You Think? Is adapting “Chainsaw Man” through films like the Reze Arc, rather than straight television seasons, the right way to do the manga justice? Which character or moment from the International Assassins arc are you most desperate to see MAPPA bring to life? And after its packed slate, do you trust the studio to give this arc the animation quality “Chainsaw Man” deserves?
See you on the next binge!
