Led into a place called Lolita Prison... As human extinction looms near, a new strain of low-age sexual Japanese encephalitis is causing a global pandemic. This virus had been secretly researched by nations and suppressed by international pandemic response medical teams without public disclosure through media or information networks. However, in Japan, various powerful factions are stirring, and an effective vaccine has yet to be sufficiently distributed nationwide. To prevent infection, the only solution is to test all bodily fluids from each individual—naturally, including vaginal secretions. Compliance with the medical teams' orders was unavoidable. The examinations proceeded swiftly: the young subjects were stripped completely naked, and all fluids—nasal discharge, sweat, and even arousal-induced secretions—were collected for testing. Though some teachers and students began to sense something was wrong, they could do nothing but face the grim reality: infection leads to excruciating pain and death within 24 hours. There was no defense against the word virus.
