Sakaki Yuuya is the main protagonist of Yu-Gi-Oh! Arc-V. He's a natural performer who trains at You Show Duel School, determined to become an "Entertainment Duelist"—basically a pro duelist who prioritizes spectacle and showmanship, just like his father did.
His signature style centers on Performapal and Odd-Eyes Pendulum monsters, which let him pull off the kind of flashy plays that get crowds invested. As he progresses through the series, he gains access to additional strategies, including Phantom Knight cards and eventually Supreme King monsters tied to his alter egos.
The manga version of Yuuya is a lot darker. He's portrayed as an amnesiac duelist known as "The Phantom" who infiltrated Leo Corporation's Solid Vision network for unclear reasons. In that timeline, his obsession is hunting down a card called "Genesis Omega Dragon," supposedly powerful enough to destroy the world if it falls into the wrong hands. More significantly, Yuuya isn't alone in his head—he shares his body with three other duelists: Yuuto (an Xyz specialist), Yuuri (a Fusion user), and Yuugo (a Synchro user). Each represents a different summoning method, and their presence complicates everything about who Yuuya really is.
