Kiseki is the biological younger sister of protagonist Takeru Kusanagi and the unwilling host of 'Hyakki Yakou,' a devastating curse passed down through the Kusanagi bloodline. Deemed an uncontrollable catastrophic threat, the Inquisition has kept her imprisoned in the deepest levels beneath the academy, far from the world she once knew. Despite her confinement, her attachment to her brother remains fierce—though warped by years of torment and isolation. Having long abandoned hope for an ordinary life, her sole remaining wish is to be killed by Takeru's hand, believing it to be her only path to peace. As the tragic heart of the story, Kiseki's suffering defines and drives every battle her brother chooses to fight.
