Kei Kurono dies after making an uncharacteristic leap onto the train tracks to save a homeless man. Instead of an afterlife, he awakens in a sealed room alongside other people who have also just died, all facing a looming black sphere. As panic and confusion spread, the ball opens to reveal weapons and sleek black suits, then issues a directive: hunt down an alien. Moments later, the group is transported to an unfamiliar location with no clear explanation or way out.

With only fragments of guidance, Kei joins forces with his childhood friend Masaru Katou and a woman he’s never met, trying to navigate the rules of a brutal, high-stakes game. Each mission drops them into a world where survival is uncertain, and every encounter threatens to be their last.
