Doraemon the Movie: Nobita's New Great Adventure into the Underworld

Nobita's desire for a world infused with magic leads him to enlist Doraemon's help in obtaining the Moshimo-box, a tool that grants wishes. As sorcery replaces the familiar realms of science and technology, Nobita finds himself struggling to master even the simplest spells, further complicating his life. When he decides to revert their reality back to its original state, he discovers that his mother has discarded the precious Moshimo-box.

The adventure takes a thrilling turn when Doraemon and his friends encounter Professor Mangetsu, a scholar of magic and mythical creatures, who warns them of a looming threat: the "star of the Underworld" is approaching Earth. With the fate of their world hanging in the balance, the group journeys into the Underworld, where they must confront the formidable Underworld King and rescue Miyoko, the professor’s daughter, who has been captured. When their efforts are thwarted, the friends resort to the Time Machine to restore order, only to find that their challenges in the Underworld persist in a Parallel Universe. Determined to resolve this crisis, they embark on a final quest to overthrow the oppressive ruler and bring peace back to both realms.
