Oni (Mystic)

Oni (妖鬼) are the result of Kijin fully returning to their roots as Elementals, making them Spiritual Lifeforms similar to Dryads or incarnated Arch Daemons. They possess an immense amount of power comparable to that of a Demon Lord, with nigh-unlimited lifespans as a result.

Abilities
Oni are said to wield supernatural powers that allow them control over nature and natural disasters. Their supernatural power, along with their immense reserves of Magicules and spiritual nature, has resulted in most of the Oni over the years being worshipped as local gods.
