[Etonmon Snjuushi] Shoujo shika Ninshin dekinai Sekai 〈dai 2-wa〉[ScanMTL]

In a bleak campus shut down by the terrifying SAIS epidemic, a frightened teenage girl discovers that the only way to survive is to become a vessel for a specially engineered male whose sperm can impregnate her, while a mysterious SAIS countermeasures bureau scrambles to administer a dangerous drug before the disease consumes everything. As the world teeters on the brink of a hellish infertility crisis, she is thrust into a nightmarish struggle of forced intimacy, desperate pleas for a cure, and the chilling promise that even a first‑tier sperm can never win, all under the looming shadow of the grim reaper.
