On Myth's journey, he comes across a giant crystal orb. He thought it was a giant demon soul gem but when he touch it, it cracked in half and she morph out of it landing on Myth. Apparently she thought that he was his master since he released her from her egg so now she travels with Myth, helping him in "any" way possible. Her name is Asuko but Myth calls her Ms. Jiggles sometimes and she's a jelly type demon. She's a Rank-X demon since there's no way of killing her species and they can't fight or cause damage to others unless they enter the enemy's body and control them.
