At Hime-chan's birthday party, Erika is filling in for her. She still can't transform back. Erika said that her grandfather, the strongest person in the land of magic, might be able to help Hime-chan. Later Sei told Daichi that that only way Hime-chan could return to her normal body was if she died.
