Academy Arc

Part 2 follows new protagonist Asa Mitaka/War Devil and Denji's life as a high school student and public Chainsaw Man.

The Academy arc opens Chainsaw Man Part 2, shifting the series' setting from the dark underworld of Public Safety devil hunting to the apparently mundane environment of Nayuta's high school in a transformed Tokyo — a city that has been so thoroughly reshaped by the events of Part 1 that even its citizens' relationship to devils and to the concept of Chainsaw Man has been altered. Denji, now attending school under a new identity provided by Kishibe, is protecting Nayuta — the reincarnation of the Control Devil and Makima's successor — while trying to maintain some semblance of an ordinary teenage life. This tonal shift is deliberate and characteristically Fujimoto: the mundane school setting becomes the terrain for exploring what Denji actually wants from life now that survival is no longer his only operating principle, and whether the version of normalcy he can access is worth the compromises it requires. New characters arrive through the school setting — Asa Mitaka, the protagonist who shares her body with the War Devil Yoru, and Yoshida, a devil hunter who operates with agendas that remain partially obscured — bringing with them Part 2's central concern: the War Devil's mission to acquire the Chainsaw Man's heart as a weapon capable of restarting the global war that Pochita's power once ended. The arc develops Asa as a co-protagonist whose self-perception as fundamentally unlovable creates a compelling counterweight to Denji's simple desire for connection. The relationship between Asa and Yoru — two entities sharing one body with opposed interests — becomes the emotional center of Part 2's early chapters, with Fujimoto using their dynamic to explore how people negotiate internal contradictions between what they need and what they have been weaponized to do.
