Doraemon: Nobita no E Sekai Monogatari

Doraemon, Nobita and his friends go to find Utopia, a perfect land in the sky where everyone lives with happiness, using an airship having a time warp function.

Doraemon and its friends open a hole in the time and they're travel to the Country of Mayana, a lost Mayan civilization in the jungle. There, Nobita will know its perfect double, prince Thio, heir to the throne. Both will decide to interchange papers to try to save to the Country of Mayana of the claws of the infernal Ledina witch and her evil forces.

Having dreamed of being in a world of magic, Nobita and Doraemon used the what-if-telephone-booth gadget to turn the world into one that is based on magic instead of science. Little did they know that demons exist and threaten this magical world.

Nobita requests of Doraemon the Moshimo-box and wishes for the world to become a place where the use of magic is possible. Witchcraft replaces science and technology and everyone makes use of it on their daily lives, except for Nobita, who, like usual, isn't very good at conjuring spells. Frustrated, he plans on returning things to their past state, but his mother threw the Moshimo-box away. One day, Doraemon and his friends meet Professor Mangetsu, who studies magic and magical beings such as goblins, and his daughter Miyoko, and are warned of the dangerous approximation of the "star of the Underworld" to the Earth's orbit. With the future of the planet at stake, the group must travel to the Underworld and pierce the heart of the Underworld King with a silver dart, as detailed in the ancient texts of "The Chronicles of the Underworld". Their attempts are, however, thwarted and Miyoko captured. Doraemon and his friends then decided to use the Time Machine to return to the past and, using Dorami's Moshimo-box, they manage to restore the Earth. The events on the Underworld continue, however, to take place in a Parallel Universe, where Miyoko is still captive. As a result, the group is once again forced to travel to the Underworld and defeat its tyrannical ruler once and for all.
