The Scorpion Eater is one of the heretical Dharma of the Kuei-Jin. It was developed by Kuei-jin who had to feed on tainted Chi to survive. Their original founder was a Devil-Tiger named Jade Scorpion, who witnessed the atomic attack on Nagasaki and was bathed in the Tainted Chi that spilled forward. Seeing that the Kuei-jin had failed, he lost all hope and pleaded to the Yama Kings to allow him to survive. The demon lords granted him this request, provided that he would not oppose their reign. The Quincunx considers all of them Akuma, even if they are not wholly slave of the Yama Kings.
