As Yuya spends countless hours trying to perfect Pendulum Summoning, Sylvio Sawatari approaches him and Zuzu. Sylvio offers to take them and their friends, Tate, Frederick, and Ally, to Leo Institute of Dueling's center court to demonstrate the Pendulum Summon. Upon arriving at the center court, Sylvio steals two of Yuya's Pendulum Cards for himself and takes Zuzu and the kids' hostage. This forces Yuya to face him in an Action Duel to save them. As Yuya traverses the Dark Town field in search of his friends, who are trapped on top of a large tower, he ends up running up against Action Trap cards. Not only Yuya is put at a disadvantage, but Zuzu and the others at risk as the field gets destroyed. Meanwhile, Sylvio manages to get both of Yuya's Pendulum Cards in his hand. With guidance from Leo Corporation's CEO, Sylvio performs his own Pendulum Summon to bring out three Dart Striker monsters.
