Chapter 205: Who?

Chainsaw Man studies the severed head of his imposter and draws a blank. Let down, the Fire Devil conjures flame in their palm and lets the fire narrate a tale. Long ago, a pair of gentle twins took in the wounded Fire Devil and nursed them back to health, telling them about Chainsaw Man as living proof that even a Devil can be a force for good. Moved, the Fire Devil adopted a Justice Devil guise and granted the twins the power to reshape themselves into embodiments of their own justice. Inspired by Chainsaw Man, the brothers began rescuing people as Fake Chainsaw Men, until the Cockroach Devil took the younger twin hostage and Denji let him die in order to save a cat.

Bitter, the Fire Devil asks whether Denji can now place the surviving twin's face, but he stays silent. They recount how the brother felt betrayed and swore vengeance, only for Denji to forget him entirely, which the Devil chalks up to his nature. Denji offers to apologize despite not grasping his offense, but the Fire Devil prefers to corner him with another choice. Before they can list the options, a toppling skyscraper smashes down beside them and the Fire Devil seemingly disappears. Buried in the debris is Yoru, insisting she is not losing even as both know it is a lie. She asks Denji if he will save her, he agrees, and he turns to confront Falling Devil.

The Fire Devil tells the backstory of the Justice twins, who admired Chainsaw Man and became Fake Chainsaw Men, and reveals Denji let the younger twin die to rescue a cat. Denji cannot recall the surviving brother, who vowed revenge. A falling skyscraper appears to banish the Fire Devil and unearths a battered Yoru, who asks Denji to save her, turning him toward Falling Devil.

Collected in Volume 22 under the Japanese title Dare?, the chapter reframes the imposter battle as a story of betrayal rooted in Denji's past choices. The Cockroach Devil is shown in flashback. Featured figures include Denji, the Fake Chainsaw Man's corpse, the Fire Devil, the Cockroach Devil, Yoru, and Falling Devil.
