Shio no Oni

Shio no Oni are similar to many other demons in that their exact origin is unknown. The most popular theory among the Kuni scholars is that they were once some other form of oni that were co-opted by the Lying Darkness and later the Shadow Dragon. Also known as shadowfire demons, the Shio no Oni is a short squat creature that could resemble a troll were it not for its bluish skin color. They seem to radiate a form of darkness around them, which keeps them constantly in the shadows. Even in the brightest sunlight. They use this darkness to coalesce into a number of large tendrils that can be used to attack their prey. Those who have survived encounters with Shio no Oni report that the tendrils burn like fire, leading some scholars to suggest they were once Fushiki no Oni that were absorbed by the Lying Darkness. Shio no Oni are intelligent and manipulative, and would prefer deception rather than confrontation. (CoR3E p. 166)
