Chainsaw Man: Reze Arc Hits Prime Video Sept 19 — And the Assassin Arc Is Next
Chainsaw Man is back in the spotlight: MAPPA's theatrical film Chainsaw Man – The Movie: Reze Arc (Reze-hen) begins streaming on Prime Video from September 19, 2026, and Studio MAPPA's next anime chapter — the Assassin Arc (Shikaku-hen) — has already been confirmed. For fans who missed Denji and Reze on the big screen, and for collectors watching where the franchise goes next, here is what actually matters.
Where and when to watch the Reze Arc movie
According to Anime! Anime!, the Reze Arc film starts streaming exclusively on Prime Video in Japan from September 19, 2026, and is included for Prime members at no extra charge. Creator Tatsuki Fujimoto reacted with amusement to the film reaching streaming, noting he had already watched it several times himself. The movie was directed by Tatsuya Yoshihara at MAPPA, the studio behind the original TV series, and its arrival on streaming gives a much wider audience a first look at one of the manga's most beloved arcs.
Availability and windows can differ by country and platform, so international fans should check their local Prime Video listing rather than assume the Japanese date applies everywhere.
Why the Reze Arc matters to Chainsaw Man fans
The Reze Arc is a turning point in Tatsuki Fujimoto's story. It introduces Reze, a mysterious girl whose romance with Denji curdles into one of the series' most emotional and violent confrontations — the debut of the Bomb Devil. It is the arc many longtime readers point to as the moment Chainsaw Man's blend of tenderness and brutality clicks into place, which is exactly why MAPPA chose it as the franchise's first film rather than a straight Season 2.
For collectors, a high-profile arc reaching streaming tends to renew demand for its characters. Reze, Denji in his Chainsaw Devil form, and Makima remain among the most-produced Chainsaw Man figures, and prize-figure and capsule lines continue to expand around the movie's momentum.
What comes next: the Assassin Arc
Rather than a numbered second TV season, MAPPA has confirmed Chainsaw Man: Assassin Arc (Shikaku-hen) as the next installment, revealed with a teaser visual and promotional video via the official Chainsaw Man site. The story follows the wave of assassins who come hunting Denji's heart — a direct continuation of the threads left dangling after Reze. As of now the format (theatrical film or TV) and a premiere window have not been finalized, with the production promising more details to come. Either way, a new arc means new character reveals, and new character reveals reliably drive the next round of figures and Ichiban Kuji lineups.
