When Kirie's DNA tests on Ayumu, Hizumi, and their respective older
brothers yield shocking results, the disgruntled Watcher confronts the
only two people who can confirm the truth of Ayumu's parentage: his mom
and dad. What she learns shakes her to the core, but how will Ayumu
react when Hizumi reveals how science has warped their fates? Will
Ayumu's resolve to save the Blade Children remain firm, or will anger
and despair cause him to waver?
