When MAPPA announced that the highly anticipated "Reze Arc" (or Bomb Girl Arc) of Tatsuki Fujimoto’s Chainsaw Man would not have a traditional 12 episode season but in favor for a theatrical film, fans were naturally anxious. Condensing an entire narrative arc into a 100-minute runtime is always a gamble. Yet, director Tatsuya Yoshihara hasn’t just successfully stitched the chapters together he has crafted an absolute blood soaked masterpiece that manages to be simultaneously heart wrenching and delightfully unhinged.
A Tender, Slow-Burn
The movie opens not with the roaring of engines, but with a quiet, deliberate intimacy. We find our feral protagonist, Denji, still grappling with the baseline concept of human affection. Enter Reze, a mysterious café employee who looks at Denji not as a dangerous weapon or a pet, but as a person.
The first hour of the film plays out like a beautifully melancholy indie romance. MAPPA leans heavily into meticulous character acting stealing glances in the rain, shared laughter, and quiet mundanity.

The centerpiece of this first half is an extended, largely anime original sequence at a nighttime swimming pool where Reze teaches Denji how to swim In the manga, it’s a beautifully simple chapter, but the movie transforms it into a sprawling, sensory experience. The animators extend the scene to showcase the literal and metaphorical distances between the two, using reflection shots in the water and a deeper, extended musical build up from composer Kensuke Ushio that grounds the tragic romance far more deeply than the manga ever could, it is one of the most genuinely romantic and visually applying sequences in modern anime.
What makes Chainsaw Man – The Movie: Reze Arc such a masterclass of an adaptation isn’t just that it copies Tatsuki Fujimoto’s manga panels it actively expands on them. Fujimoto is famous for his breakneck pacing and cinematic, minimalist storytelling; he often leaves emotional gaps between panels for the reader to fill in. Director Tatsuya Yoshihara and the team at MAPPA use the feature film format to breathe luxury into those quiet spaces, lingering on details the manga rushed past.
Meticulous Character Animation and "Extra" Romance
The first half of the film heavily elaborates on Denji and Reze’s budding relationship. Where the manga spent just a few panels establishing their chemistry at the rainy telephone booth and the café, the movie introduces beautifully fluid, anime-original character acting. We see the subtle, micro expressions of Reze’s playful teasing and Denji’s goofy, heart eyed infatuation.
The Ultimate Feast of Carnage
Once the mask drops and Reze’s true identity as the Bomb Devil is revealed, the film shifts gears. The second half is an absolute adrenaline shot.
If Season 1 of the anime was celebrated for its cinematic, live action style framing, the Reze Arc movie pivots toward bombastic, maximalist spectacle. The action is frantic, gory, and unapologetically absurd. The animation reaches a fever pitch during the climax, featuring a sequence where Denji literally rides a giant shark devil into battle against an explosive, city level threat. It’s easily the most ridiculously fun, jaw dropping set piece of any shonen film in years.

The issues
If there is any critique to be made, it’s that the movie occasionally falls victim to its own scale. During the final, massive confrontation, the visual effects heavy with neon color splashes inspired by Fujimoto’s manga covers can become so densely layered and kinetic that the choreography becomes difficult to track. Additionally, because it is a direct continuation of the series, it offers zero hand holding for newcomers. If you haven’t watched Season 1 or read up to volume 6 of the manga, you will be utterly lost.
The Verdict: A Triumph for Shonen Anime
Chainsaw Man – The Movie: Reze Arc works so well because it honors the duality of its source material. It understands that Chainsaw Man isn't just about chainsaws and gore; it's about the profound loneliness of a boy who just wants to be loved, and the tragic reality of the world he lives in.
Come for the jaw dropping animation and a man riding a shark; stay for the heartbreaking, bittersweet tragedy that proves why this story belongs on the biggest screen possible.
