The Akuma, or Devil-eaten, are the persons who have abandoned virtue and have cast their lot in with the Yama Kings. Some Yama King like to corrupt Kuei Jin, while others take exclusively Hengeyokai or Mages. The Yama Kings give them power and access to Tainted Chi and Bile Shintai, but will also punish them if they seem to be a failure in their new masters' eyes. While similar, Scorpion Eaters are not yet akuma but are merely P'o-ridden Kuei-jin who feast upon Tainted Chi and still possess their souls. Most Kuei-jin do not care about those small differences but destroy both when they can.
