Dark Yugi and Mokuba's pre Death-T Capsule Monster Chess game was a Shadow Game of Capsule Monster Chess which took place shortly before the events of Death-T. In the manga, it is the first of Dark Yugi and Mokuba Kaiba's two games of Capsule Monster Chess. This event does not happen in the first series anime and is replaced with Miho, Dark Yugi and Warashibe's Capsule Monster Chess game.
