The Black Clown game store releases a new game, D.D.M., which makes everybody in town line up to buy it. Yugi and his friends go to the store to check it out as well, but Yugi is lured by Mr. Clown, who seeks revenge for losing to Yugi's grandfather, and set up to play D.D.M. with his son, Ryuji, who is none other than the creator of the game.
Yugi is forced to face Ryuji in a D.D.M. match. However, Ryuji holds an overwhelming advantage being the creator of the game, and immediately takes the lead against Yugi, who can't count on his other self without his Millennium Puzzle.
Yugi breaks down seeing his Millennium Puzzle beign undone by Mr. Clown, but Ryuji tells his father to stay out of it, because the match was between him and Yugi. Yugi recomposes himself in order to continue the game and obtain his Millennium Puzzle back, but Ryuji turns the tables and corners Yugi once more. At that time, Dark Bakura shows up.
Yugi seems to be in a hopeless situation. Considering himself the winner already, Ryuji trives to solve the undone Millennium Puzzle, but seems not to be able to. Bakura declares that no one can solve the Puzzle besides Yugi, and that he will be the winner of this game.
