Action Duels, which enable duelists to fly and swing alongside their Duel Monsters, are sweeping the globe. Thanks to a technological leap, the "Solid Vision" system now gives Duel Monsters physical mass.
Yuuya Sakaki is the son of Yuusho Sakaki, who founded the You Show Duel School in Miami City. Yuusho insists that duels are not instruments of war, but rather tools to bring smiles to people, leading him to create Entertainment Dueling. However, at the peak of his fame, Yuusho vanishes and fails to appear for his match against Strong Ishijima, the Action Duel champion. Though wounded by this sudden disappearance, Yuuya swears to become an Entertainment Duelist just like his father.
Years later, during a duel with Strong Ishijima, Yuuya's desperate need to win sparks a miracle. His pendant glows, transforming his cards into Pendulum Cards, which allows him to perform a Pendulum Summon—a summoning method unknown to both him and the world—catapulting him to instant fame. In response, Reiji Akaba, CEO of Leo Corporation and founder of the elite Leo Duel School, begins manufacturing new Pendulum Cards to incorporate Pendulum Summoning into the system. Thus, the enigmas surrounding Pendulum Summoning and Yuuya's father start to unfold, and Yuuya gradually learns what it truly means to be an Entertainment Duelist.
