School Arc

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.

In Their Own Story

Denji and Reze share intimate moments, including skinny dipping in an outdoor pool where she teaches him to swim. Their relationship is interrupted when Reze is ambushed by an assassin; she kills the man and allies with his Typhoon Devil partner. At a festival, Reze asks Denji to run away, but realizing another woman exists in his life (Makima), she reveals her identity as the Bomb Devil. A massive battle ensues: Beam retreats with injured Denji to a Public Safety office, where they meet Aki and Angel before escaping by car as Reze slaughters other hunters. In the chase, Denji is revived using a casualty's blood and rides Beam's shark form to fight. The Typhoon Devil pulls the Angel Devil into its winds until Aki catches his shirt; Aki secures Angel by grabbing his bare hand, sacrificing two months of his remaining two-year lifespan. Denji and Beast kill the Typhoon Devil, but Reze severely injures Beam. On the coastline, Denji binds Reze with chains and jumps into the water to neutralize her powers as they sink. The next morning, Reze admits she never had feelings for him, though Denji counters that she wouldn't have taught him to swim if that were true. He asks her to meet at the café the next day. In the aftermath, Kishibe reveals Reze's history to Aki. As Reze heads to a train, she changes her mind but is intercepted by Makima and attacked by Angel in an alley. Bleeding out, she wonders why she didn't kill Denji earlier and admits she never went to school. The story ends with a post-credits scene where a depressed Denji holds flowers for Reze, who never appears; Power arrives instead, leading him to eat the bouquet.

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.
