Yuto
A young boy from the Xyz Dimension who resembles Yuya in appearance. He has the power to cause real damage in duels. Along with Shay, Yuto is on the search for Lulu who is currently captured by Leo Akaba. Yuto went to Standard Dimension after hearing Shay went there to look for Declan and followed him there. Following his arrival, he mistook Zuzu as Lulu and came to her aid when she was about to duel Sylvio, taking over the duel and defeat Sylvio. Since then, he observed Zuzu until he saw her training to learn Fusion summon, convincing him that she is not Lulu. Yuto and Yuya are both alike, they both care for their friends and do not want to hurt anyone. At the same time Yuto and Yuya are different, while Yuto is serious and cold, Yuya is positive and energetic. Unlike Shay he is not reckless and impatient, though if his anger gets the better of him, he becomes aggressive. After his defeat at Yugo's hand, he entrusted his Dark Rebellion Xyz Dragon to Yuya and got absorbed into him, initially taking over Yuya's body whenever the need presents itself with the two sensing each other. But since their arrival in the Xyz Dimension, Yuto and Yuya are able to freely communicate with each other and even swap bodies. Yuto's presence inside Yuya was kept a secret from everyone until during the duel between Shay and Kite, Yuto talked while accidentally possessing Yuya's body. Yuto ended up succumbing to Zarc's power in Yuya's Duel against Yuri and Yuya completes their original self's resurrection immediately afterwards. Due to Riley's actions when the dimensions once more separated, having aided Yuya in resisting Zarc, Yuto was presumed to have died until Shay sensed his presence within Yuya's body following the former's loss. During Yuya's duel with Jack, Yuto finally reveals himself to Yuya as he and their counterparts give Yuya their support. Yuto uses a Phantom Knights deck and his ace monster is Dark Rebellion Xyz Dragon.
