From the New World
Saki realizes that the Akki was conditioned to suffer the death feedback from killing Monster Rats instead of humans. Kiroumaru then confronts the Akki disguised as a human, resulting on the deaths of both, after asking for Saki to make sure that at least his colony is spared from the humans' vengeful wrath. With the rebellion finally supressed, Yakomaru, having renounced to his title and once more addressing himself as Squealer, is tried and sentenced to "Eternal Hell", with his body suffering excruciating pain while being regenerated indefinitely. However, Satoru later reveals to Saki that upon analyzing the Monster Rats' DNA he discovered that they were created by infusing mole rat DNA into ordinary humans to prevent them from being a threat to the humans with telekinesis. Saki then pays a visit to Squealer and sure that he was already punished enough, puts him out of his misery. Ten years later, Saki and Satoru get married, and as she expects their first child, they desire that the world soon becomes a better place for its sake.

From the New World
Following a sudden outbreak of psychokinesis in 0.1% of the population, a rapid transformation swept the world. The godlike ability to manipulate matter remotely turned many power wielders to violence, inciting a long period of upheaval. Finally, after a chaotic era shaped by the rise and fall of oppressive regimes, the psychic humans were able to achieve a fragile peace by isolating their society, creating a new world bound by complex rules.
In the town of Kamisu 66, 12-year-old Saki Watanabe has just awakened to her powers and is relieved to rejoin her friends—the mischievous Satoru Asahina, the shy Mamoru Itou, the cheerful Maria Akizuki, and Shun Aonuma, a mysterious boy whom Saki admires—at Sage Academy, a special school for psychics. However, unease looms as Saki begins to question the fate of those unable to awaken to their powers, and the children begin to get involved with secretive matters such as the rumored Tainted Cats said to abduct children.
Shinsekai yori tells the unique coming-of-age story of Saki and her friends as they journey to grow into their roles in the supposed utopia. Accepting these roles, however, might not come easy when faced with the dark and shocking truths of society, and the impending havoc born from the new world.
