Stigma is a secret organization in the FanFiction High School DxD: True Maou written by demonicjester01. Its objectives consist of maintaining a nonviolent status between all of the mythological factions (therefore making them direct opponents to the Khaos Brigade), as well as slaying the abominations known as Apostles. Their ultimate goal is to slowly, but surely bring about a new world by "destroying" the current one.
