Kousekibyou or crystallization disease, is a condition where the person grows crystal all over their body until they are fully consumed.

It's strongly believed that Kousekibyou is based on oripathy from arknights.

A condition picked up when coming into contact with Originium shards, ingots and Originium particles in the air. A hard black substance starts growing on their body, which is part of the crystlization proces.

The crystallization will continue to spread through the Infected's body, causing pain and discomfort and inhibiting their ability to respirate and properly intake and distribute nutrition, which eventually causes organ failure. Upon the Infected's death, their body will eventually disintegrate in a way similar to spontaneous combustion — the crystals on their body start to glow, leaving behind Originium particle dust that can cause secondary Oripathy infections if the Infected's body is not isolated properly
