Zane came to the conclusion that Syrus had done a lot of of growing up when he'd been away. Syrus defended Zane, telling David not to insult his brother. He witnessed Syrus defeated in a Duel by David, with David coming to the conclusion that if the brother of the Kaiser is that weak, perhaps the Kaiser himself isn't as strong as his reputation implied. A tournament was organized, with the winner being permitted to Duel Zane.
He returned to Duel Academy months later alongside two American students - David Rabb and Reggie MacKenzie. Zane studied abroad in America with Atticus, where he represented Duel Academy well. When they departed for Duel Academy, the title would be won by Chazz Princeton. During this time, Zane and Atticus met American Duelist Aster Phoenix. The two "dominated" the title of Junior Champion. Zane competed in the junior leagues when he was a child, alongside Atticus. He came to this determination after witnessing Syrus throw a Duel against a friend of his named Masao.
He believed that Syrus was too nice to be a Duelist as he cared for his opponents too much. When they were children, Zane gifted Syrus with " Transformation". His "Kaiser" nickname is retained even in the English edition of the manga. He is at the top of the class, and is described as "Number one ranked in practical skills".
