Yumemi is just an ordinary girl except that can see the islands of the Heavens floating in the sky. Although her friends support and believe her even though they can’t see the Heavenly Kingdoms themselves, Yumemi often feels that she is “different” from everyone else and there is something wrong with her because she sees things no one else can.
Lady Ryuely discribes Yumemi as “… just an ordinary child with unlimited possibilities”.
In Munto’s vision Yumemi holds the power to open the future of the Heavens, she is the key to saving the seven Heavenly Kingdoms from destruction. At great personal risk he travels to the Lower World to find the one he calls the “Girl of Destiny”.
