Each One's Determination

While everyone is still coming to grips with this entire situation, Leon appears before Aichi and his friends. He not only tells them the solution to returning Reversed fighters to normal is defeating them in cardfights, but he also informs them that he plans on going to fight Kai and wants Aichi to join him. He agrees, but then Leon proposes to have a fight instead. Shortly into the battle, Leon calls the fight off, noting that Aichi's heart is locked by the thought of having to fight Kai. Leon leaves after further deeming Aichi as being unable to achieve victory in his current state and unworthy of fighting alongside him. While Aichi looks inside himself for answers, Naoki follows Leon outside and says that he wants to go with him in Aichi's place. Leon decides to test Naoki's skills in a cardfight with Shingo observing them. Meanwhile, Jun Mutsuki gathers his fellow underground fighters in an effort to counterattack the Reversed fighters until Miwa appears before him. Quickly realizing Miwa's Reversed state, Jun cardfights him. Although he drives Miwa to the brink of defeat, Jun is unable to deal the final blow to him. Miwa wins using Dauntless Dominate Dragon "Reverse", leaving the now-Reversed Jun to take on the other underground fighters. After beating Naoki several times, Leon finally decides to leave until Shingo intervenes. Before departing, Leon recommends for Naoki and Shingo to take care of Aichi. So, the two decide to train in preparation for the big confrontation.
