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.
Saki comprende che il meta-demone è stato condizionato a subire la ritorsione mortale dall'uccisione di Mostroratti e non di umani. Kiroumaru quindi, dopo aver chiesto a Saki di assicurarsi che almeno la sua colonia venga risparmiata dalla furia vendicativa degli umani, affronta il meta-demone travestito da umano
