Kansen 3 ~Shuto Houkai~

Kansen 3 ~Shuto Houkai~ is a dramatic ADV that picks up four years after the harrowing events of Kansen 1 and 2. The terrifying plague that devastated Japan's Tohoku region has been suppressed by strict quarantines and a vaccine, now fading into a bad memory. But the unknown virus lingers, and an inescapable doom soon descends upon Wataru Ayase and his loved ones, trapping them in Tokyo—a city transformed into a hellish madhouse. Featuring heroines including a non-blood-related sister, a senpai, a childhood friend, and a classic tsundere, this story blends drama, yakuza intrigue, and illness with multiple endings.
