Chainsaw Man: Why MAPPA Made a Film Instead of a Season 2

When Chainsaw Man’s first anime season ended in December 2022, the expected industry pattern was a quick Season 2 announcement. Most popular shonen manga adaptations follow this template — the first season ends, the announcement of a second season comes within months, the second season ships within 18-24 months.

Chainsaw Man broke that pattern. MAPPA waited until late 2023 to announce that the next adaptation wouldn’t be a Season 2 at all. The Reze arc — Part 1’s mid-arc encounter with the Bomb Devil — would be adapted as a theatrical film, releasing in 2025. There would be no immediate Season 2 of the TV anime. The decision generated extensive industry discussion and fan complaint at the time.

In 2026, with the Reze film released and its reception clear, the choice looks structurally vindicated. What MAPPA was actually doing — and what the decision tells you about how the studio is reorganizing its production model — is worth understanding.

The first-season reception, stated correctly

Chainsaw Man’s first 12-episode season was, technically, an extraordinary production. The animation was film-quality throughout. The character work was strong. The opening sequence (Kensuke Ushio’s “KICK BACK”) was widely praised. By any technical standard, the show was a major MAPPA production.

What made the reception “polarizing” was not the quality but the commercial expectations. Chainsaw Man’s manga had been one of the most-discussed Shonen Jump series of the early 2020s. Pre-anime sales projections were high. The Blu-ray sales for the anime came in below those projections — not catastrophic, but lower than expected for a show of its visibility.

The internal MAPPA discussion that followed (some of which became public through staff interviews and animation industry press) reflected the same question that comes up at every studio after a major production: does this work hit the commercial returns it needed to justify the budget? For Chainsaw Man, the answer was complex. Yes the show was a critical success and viewer-engagement success on Crunchyroll, but the Blu-ray returns were lower than the studio’s internal modeling had projected.

This is the structural reality MAPPA was operating under when it made the Reze decision. The studio needed to figure out how to continue adapting Chainsaw Man without committing to a multi-season TV pipeline that might not pay back at the same margins.

Why a film instead of Season 2

The Reze arc occupies chapters 38-52 of the manga — roughly 14 chapters that depict a self-contained encounter between Denji and the Bomb Devil. The arc is structurally distinct from what came before and after it, with clear pacing and a discrete climax. It’s one of the cleanest “movie-length” arcs in the manga.

The Reze arc was selected to be a film because three things lined up:

The arc is structurally suited to film format. A film needs a beginning, middle, and end that work as a 90-120 minute experience. Reze is one of the manga’s tightest arcs. Adapting it as a film required less structural manipulation than adapting longer multi-arc material.

Film economics are better than TV economics for high-budget animation. The Chainsaw Man film cost more per minute than the TV episodes did, but film theatrical revenue plus eventual streaming and physical media releases pays back at higher margins than TV anime’s broadcast-then-streaming model. Demon Slayer: Mugen Train had demonstrated this on a much larger scale.

Production teams could work on the arc without the constant pressure of weekly broadcast. The Chainsaw Man Season 1 production was, by all accounts, intense for the MAPPA team. A film production allowed the same staff to work on a self-contained Reze adaptation without the structural pressure of weekly delivery. This matters specifically for MAPPA’s overall production stress narrative.

What the Reze film actually delivered

The Chainsaw Man: The Movie - Reze Arc released in Japan in October 2025 and internationally in late 2025 to early 2026. The reception was, in retrospect, what MAPPA had been hoping for.

Critical reception was strong. The Reze film was widely praised as one of the year’s best-animated anime films. The action sequences, the character work, and the structural pacing of the adaptation were all noted as superior to typical TV anime production.

Box office performance was strong. The film opened at #1 in Japan and stayed in the top three for multiple weeks. International releases performed within studio expectations.

Production staff testimonials were more positive. The film’s production was less publicly stressful than Chainsaw Man Season 1 had been. The reduced pace and the focused scope of the project allowed the team to produce work they were proud of without the burnout dynamics that had characterized the TV production.

Reze’s character work landed. The Reze character — a girl with a complicated relationship to the protagonist — has substantial fan engagement in the manga. The film’s adaptation of her arc, including the relationship with Denji, was widely considered well-handled.

The vindication of the film choice was not just that it worked financially, but that it produced better work under more sustainable conditions than Season 2 would have.

The structural implications for MAPPA

What the Reze film represents, structurally, is MAPPA experimenting with alternative production models for franchise content. The studio has been signaling for years (through public statements from CEO Manabu Otsuka and senior producers) that the standard TV-anime production cycle is not sustainable for prestige animation. The Reze film was the first major experiment with an alternative.

If the model holds — if MAPPA can continue producing self-contained arcs as theatrical films rather than seasonal TV anime — it represents a meaningful shift in how high-end anime production gets funded and structured.

What’s not yet clear is how this model scales. Chainsaw Man has a long manga (still ongoing into Part 2). If MAPPA does each major arc as a separate film, the adaptation timeline extends substantially. Whether this is acceptable to fans, manga publisher Shueisha, and the broader market is the open question.

What’s also worth understanding is that the Reze film does not preclude an eventual Season 2 of the TV anime. MAPPA has been clear in public statements that further Chainsaw Man content is in development. The structural choice was to release the next major arc as a film rather than as a TV season; future arcs may be different formats.

What Part 2 of the manga does to the adaptation strategy

The structural challenge for any future Chainsaw Man adaptation is what to do with Part 2 of the manga (currently ongoing on Shonen Jump+, with approximately 200 chapters as of early 2026). Part 2 introduces a new protagonist (Asa Mitaka), a new setting (a high school rather than Public Safety), and a different tonal register. Adapting it requires either treating it as a continuation of Part 1’s structure or treating it as a soft reboot.

MAPPA’s current public position is that Part 2 adaptation timing depends on where the manga is in its serialization. The studio doesn’t want to adapt Part 2 until the manga has established the full structure of that part, which probably won’t happen until 2027 or 2028.

In the interim, the Reze film is the only major Chainsaw Man anime content in production. There has been discussion of additional Part 1 arc adaptations (the Bomb Devil arc, the Future Devil arc, the International Assassin’s arc) but no formal announcements as of 2026.

What this means for the broader Chainsaw Man franchise

The franchise’s position in 2026 is interesting. The manga continues serializing Part 2. The anime franchise has the first season and the Reze film. The video game tie-ins, merchandise, and licensing operations continue. But the property is not in active TV-anime production, which is unusual for a franchise of Chainsaw Man’s commercial scale.

This is, in some ways, the point of MAPPA’s approach. The studio is decoupling the manga’s continuous serialization from the anime’s adaptation cycle. The anime continues but at a slower, more deliberate pace, with each adaptation calibrated to be a quality production rather than a fast follow-up to keep the franchise visible.

For fans, the practical reality is that Chainsaw Man content in 2026 is the first TV season (available on Crunchyroll and other platforms), the Reze film (available on theatrical release and streaming as of early 2026), and the ongoing manga (Shonen Jump+ for current chapters, VIZ Manga for English collected volumes).

What the Tatsuki Fujimoto factor means

It’s worth noting that Tatsuki Fujimoto (the manga’s creator) has been involved in production decisions for the anime franchise. Public statements from MAPPA and Shueisha have credited Fujimoto with input on the decision to make the Reze arc a film. Whether this collaboration continues, and what other input Fujimoto has on future anime adaptations, will shape how the franchise develops.

The 2026 verdict

Two years after the Reze decision was announced, the verdict is mixed but tilting positive. The film delivered. The production model was less stressful. The financial returns met expectations. The structural choice to depart from the standard TV-anime sequel model worked in this specific case.

Whether the model holds for the next decade of Chainsaw Man adaptation is the open question. What’s clear is that MAPPA’s specific approach — using film format and self-contained arcs to reduce production stress while maintaining quality — is now a model the rest of the industry is watching.
