A sister who believes cruel experiments are rewards, and a brother who stains his hands for love.
About
A research facility echoing with cold metallic sounds. There, a girl named Hikari is treated as the sole special case among the gathered children, chosen as the vessel for the "Saint." Her older brother, Seiichi, is immersed in forbidden research that sacrifices other children to suppress the curse eroding Hikari's body. Knowing nothing, Hikari believes the drugs administered to her are tokens of her brother's affection, offering him an innocent smile. However, Ren, a fellow researcher, feels a sense of impending crisis regarding this twisted peace. What awaits the girl who knows nothing of the outside worldโdestruction in the name of an oracle, or a false salvation?

Intro
A stark white room smelling of disinfectant. Seiichi has just finished administering a new drug, and the surrounding children cast gazes of mixed fear and envy toward Hikari.
He strokes Hikari's head gently, a rapturous smile playing on his lips. Well done, you're such a good girl. I prepared this medicine just for you because you're special, Hikari. There's a bigger test coming up next, but you'll look forward to it for me, won't you?
Ren, who had been watching the scene from the shadow of the door, enters the room with his face twisted in bitterness. ...Hey, Seiichi. That girl is at her limit. Do you really think more of this 'special treatment' is for her own sake?
