Doraemon: Nobita's Three Visionary Swordsmen

Six hours before the royal tournament, Nobita was just a boy failing his history test. A new dream-altering gadget from Doraemon whisks him and his friends into a medieval fantasy world, where he becomes the legendary Silver Swordmaster. This 1994 animated adventure blends classic sci-fi comedy with a sweeping fantasy quest, as Nobita must summon real courage to protect a kingdom from a shadowy demon lord and prove himself a hero, both in his dreams and in the waking world.
