Evil aura. Scorn, spite, fear, and other negative emotions give rise to stigma, and those afflicted by it are compelled to do evil.
When a world becomes infested with stigma, the humans go mad, the earth is blighted, and evil kami and ayakashi rampage unchecked. Legends tell of such a savage age, long ago in the ancient past.
To prevent such a calamity, kami devote themselves tirelessly, day and night, to the cleansing of stigma.
