Doraemon: Nobita's Great Adventure in the World of Magic (1984)

Overview

Nobita, currently obsessed with fantasy fiction, wishes upon Doraemon's Moshimo-Box for the world to have real magic and sorcery. This doesn't go as he'd hoped, of course, and Nobita must navigate the strangely-bureaucratic magical world he'd made while also learning to conjure on his own in preparation for an attack by the underground-dwelling Demon World.
