The final act jumps to adulthood. Saki and Satoru are thrust into a brutal war triggered by Yakomaru (Squealer), a highly intelligent leader of the Queerbrats (humanoid mole-rats). Squealer exploits a loophole in human biology by raising a human child in secret, turning her into a Gouma (Fiend)—a human who doesn't possess the Death Feedback mechanism because she believes she is a Queerbrat. This single child becomes a weapon of mass destruction capable of wiping out the entire human race.

A: Their death serves the plot by creating the Fiend. It also highlights the Queerats’ desperation—they realized that only a human child raised without Death Feedback could destroy the psychics. It is a dark parallel to how humans once created the Queerats.
