Queen Deity

Queen Deity (クィーン・ディーッティー Ku~īn dīttī) is the ruler of Crystal Paradise. She is the ultimate guradian, thus all the powers of the cures came from her. She is also the mother of Prince Yoshiaki (Yoshiaki-sama) who is now acting as the temporary ruler after she collapsed and entered a deep slumber.

History
Queen Deity ruled the Crystal Paradise and managed to keep her world as well as the other universe flourished with life. But after a while, she noticed that a group of people coming from another universe kept attacking the different worlds including Crystal Paradise. These people were the people of Calamity Sphere, the Fiasco Class together with their ruler Havoc Empress. She tried to ward them off and fight back but she couldn't go on anymore thus she told her people that they should find the next generation of the Guardian Cures in order to help them. She scattered and transformed her essence into Cosmos Pouch in order for the enemies to not get them. She fell into a deep slumber after this.
