The game follows Syahata, a seemingly ordinary young woman, who wakes up to find her city overrun by a grotesque, fleshy parasite. The "infection" doesn't just kill—it mutates. Victims fuse into walls, twitching piles of meat, or become shambling monstrosities driven by a singular will. Syahata’s "bad day" involves navigating these bio-mechanical labyrinths, avoiding instant-death encounters, and uncovering notes that reveal the parasite is semi-sentient, lonely, and horrifyingly hungry.
