K.C. Cup Preliminaries and Semi-Finals

"K.C. Cup Preliminaries and Semi-Finals" is an unofficial name for an instrumental composition from the video game Yu-Gi-Oh! Worldwide Edition: Stairway to the Destined Duel.

This is the theme music that plays during the openings of (and thus, before Dueling in,) the preliminary and semi-final rounds of the K.C. Cup Tournament in the game.
