The world reflected in the eyes of a girl looking up at the sky

Hidaka Yume (voiced by Mai Aizawa) is an ordinary girl. There is an unknown secret hidden deep in her heart. In the vast sky, she dreams that she can sometimes see incredible islands floating in it. However, it seems that she is the only one who can see this scene. One day, a red-haired boy named Muente (voiced by Daisuke Ono) suddenly appeared in front of Mengmeng. It turned out that the world was divided into two parts: the "heavenly realm" and the "earthly realm", and Muente came from the Sorcerous Kingdom in the heavenly realm. For a long time, a wonderful force has maintained the balance and operation of the two worlds. Now, this force is gradually drying up, and the heavenly world has fallen into chaos. If this continues, sooner or later, disaster will affect the earthly world, and Dream is the only person who can save it all.
