In the Kingdom of Hyrule, a mysterious man named Octavo uses a magical Lute to put Hyrule's king, as well as Link and Zelda, to sleep, before using the Triforce of Power to turn his Lute into a Golden Lute. In this time of need, Cadence is mysteriously transported to Hyrule by the Triforce and manages to wake up Link and Zelda. While Cadence goes off to try to find a way home, Link and Zelda travel across Hyrule to find and defeat Octavo's four champions, who each possess enchanted instruments containing musical power. After Link and Zelda, soon rejoined by Cadence, obtain the instruments and enter Hyrule Castle, Octavo reveals that he and his champions were meant to be used to battle against Ganon, who will take over Hyrule in the future. Finding himself defeated, Octavo opens a portal into the future, where Link, Zelda, and Cadence confront Ganon and combine their forces to defeat him. With help from the Golden Lute, Link and Zelda use the power of the Triforce to try and send Cadence back to her own world.
