He came to the current timeline by his father Yusho to find the one who created a card called "Genesis Omega Dragon" (G.O.D) which has the power to determine the fate of the world. But Yuya finds opposition in Leo Corp's president Reiji Akaba, who is also from the future and blames Yusho for destroying their era when he stole the G.O.D. card from his father Leo Akaba. Furthermore, unbeknownst to Yuya, Yuto, Yugo, and Yuri were originally separate youths who somehow got merged into Yuya's body and have been altering his memories of them to conceal a horrible truth.
