Dark Yugi and Seto Kaiba's school Duel was a Shadow Game of Duel Monsters in the Toei Yu-Gi-Oh! anime. It was the first Duel between Dark Yugi and Seto Kaiba.
It is based on a Duel from the manga, although the result is changed to a DRAW, rather than having Dark Yugi win.
At the end of the Duel, Kaiba Summoned "Gremlin" and used it to split the field in two, resulting in a DRAW.
