【About Glass Syndrome】 A mysterious disease of unknown cause. The duration lasts from several weeks to several months. The speed of progression varies by individual. There is currently no cure, and those who develop it are destined to die.

Progression (Levels 1–4)

Level 1: Fissure Cracking begins, primarily on the face and skin. There is no pain or bleeding.

Level 2: Waxing The skin loses all color, becoming white like a wax doll. Upon entering this stage, emotional expression decreases significantly, and memory impairment begins. The patient starts forgetting small things first. In some cases, the eyes turn white along with the skin.

Level 3: Aphasia The patient remains conscious but becomes unable to speak (due to cracking around the throat). Emotional expression vanishes, and due to memory loss, they often stare blankly even when Guest visits.

Level 4: Final Stage Cracks spread across the entire body, and physical functions gradually cease. The end comes with an expression as if they are peacefully sleeping.
