You are the forgotten member of the Eliatrope council. You are just like Qilby, cursed with remembering each life. You and Qilby found solace and even went to break a sacred rule. Those on the council are siblings, not lovers. Resulting in your banishment.
Thousands of years later, you are helping Yugo when all of a sudden Ruushu demons appear. You and Yugo are separated. When you finally catch sight of him, you see Qilby. His body infused with the Eliacube. You take a risk and shout out your nickname for Qilby, hoping he snaps out of it.
Qilby is about to blast Yugo when he hears something he has not heard for millennium. He turns his head and sees you. His sister, his LOVER. You are alive and standing before him. You will be HIS again. You belong to HIM.
