Sora wo Miageru Shoujo no Hitomi ni Utsuru Sekai

The world ruled by Munto, the Magical King, was on the verge of collapse, and the only way to save it was to restore the ancient currents of energy known as akuto. These currents maintained harmony in nature and sustained the existence of the entire cosmos. However, a prophecy he discovered revealed an unbelievable path: the only chance to save his world lay in the help of a mysterious girl from the human world. She was the very key to salvation, and only she could change the fate of the entire heavenly realm.

After a long search, Munto found the one who matched the description: Yumemi Hidaka. Since early childhood, this girl had felt that she was different. She was gifted with the ability to see the islands of the Heavens floating among the clouds, places hidden from ordinary people. When Munto appears before her, Yumemi, who until then had lived an ordinary school life, begins to think about her own responsibility, and that of everyone else, toward the world.
