Leon Souryu
While Jillian and Sharlene take on Ren and Asaka in a tag fight, Kai begins his battle with Leon. As the two fighters clash, Leon reveals his past. As it turns out, the legend of a child who would call forth the "wind" and lead the second coming for both the Souryu family and Aqua Force clan was just a fairy tale made up by the Souryu chief only meant to provide (false) hope to the young Leon, Jillian, and Sharlene. Eventually, the Souryu and Aqua Force would be forgotten and die out. Desperate to find power to save both, Leon met Void, who offered him Psyqualia. He accepted the power, and thus Leon became that prophesied Souryu child, turning that fairy tale into a reality. Back to the cardfight, Kai, who is furious at Leon's selfish actions of betraying the 3 clans, rides Dragonic Kaiser Vermillion and announces that he will defeat him.

He reveals that the Royal Paladins, Shadow Paladins, and Kagero leaders have been captured, and the only way to free Cray is for the Vanguard fighters to use a new power- Limit Break. Because the Royal Paladins lose the ability to fight, Aichi's deck is changed to be a Gold Paladin deck. Aichi and his friends must now win the Vanguard VF Circuit if they are to learn more about the occurrences on Cray and free their old friends.
