School Arc

A bomb-themed romance unfolds between a shark fiend, a chainsaw man, and an agent who never attended school.

School Arc details 'Chainsaw Man – The Movie: Reze Arc,' a 2025 film directed by Tatsuya Yoshihara and produced by MAPPA. This adaptation follows the events of manga volumes five and six, serving as a direct sequel to the first anime season. The narrative centers on Denji's complex interactions with Makima and his subsequent encounter with Reze, a girl he meets in a phone booth during a storm. While the film features school-related moments, such as Denji sneaking into a school at night to skinny dip with Reze, it does not follow a storyline where Denji attends high school or navigates a traditional academic setting. The content strictly focuses on the Bomb Devil arc's specific plot points rather than a general school life narrative.

Lore & Background

Following Katana Man's defeat, Public Safety leader Makima assigns the Shark Fiend Beam as Denji's temporary partner while Power undergoes blood draining. The narrative shifts to a date where Makima takes Denji to a six-film movie marathon; both dislike most films but are moved to tears by the final one, during which Makima tells him he has a heart capable of feeling. Meanwhile, Aki Hayakawa is paired with the Angel Devil, whose touch shortens human lifespans, creating tension due to Angel's apathy.

The core lore revolves around Denji meeting Reze in a phone booth and visiting her café. They later sneak into her school at night for a swim, a moment that establishes their connection before the plot takes a violent turn. Reze reveals her true identity as the Bomb Devil after biting out Denji's tongue during a festival fireworks display, revealing she was a Soviet agent experimented on as a child who never actually attended school.

Reader's Guide

To understand this arc, note that it adapts manga volumes five and six and is released as a film on September 19, 2025. The story begins after Katana Man's defeat with Makima assigning Beam to Denji. Key turning points include the movie marathon date with Makima, the night swim at the school pool with Reze, and the festival reveal where Reze bites out Denji's tongue. The action guide involves three distinct phases: the initial ambush of Reze by an assassin, the car chase through city streets involving Aki, Angel, Beam, and Denji against Reze and the Typhoon Devil, and the final underwater confrontation on the coastline.

Viewers should pay attention to the specific mechanics of the fight: Angel's lifespan-shortening touch (costing him two months), Denji riding Beam's shark form for tactical advantage, and the use of water to suppress the Bomb Devil's abilities. The narrative concludes with Reze's death in an alleyway after a change of heart, followed by a post-credits scene depicting Denji's depression over her absence.
