Demonic Illusion: World of Glass

This jutsu traps the opponent in a world where literally everything is made out of glass, that breaks down in sharp glass spikes with the slightest move, even by breathing. So if the victim trapped in the genjutsu would breath, it would feel if glass was piecing there lungs. If they would take a step, it would feel like their leg was pierced and so on. This jutsu has been known to be extremely painful.
