Oriax

A high-ranking demon who enjoys the sorrow and despair of humans. It is very unusual for demons of their class to form a contract with humans, but because gaining their help would lead to great wealth and power, many summoners continue to find a way to summon them to do their bidding. But these high-ranking demons aren't gullible, and their sly disposition makes it difficult to form a fair contract. Because of this, most people end up losing their souls to the oriax.
