Oni (Mystic)

Fair Oni (妖鬼) are a Semi-Spiritual evolution of Kijin, with greatly improved magical characteristics making them closer to their Elemental Spirit fairy ancestors than Humans. Their powers can even reach the level of unawakened but "mature" Demon Lord Breeds like Carrion.

All the survivors from the Ogre village except Shion evolved into Fair Oni during Rimuru's Harvest Festival, while Shion evolved into a Wicked Oni instead.
