15화: 나오키가 아이슬트 과일을 들고 레온과의 또 다른 전투를 위해 귀환하다

15

By dinnertime, Naoki and Kamui return to Leon and present him with fruit that only grows on that islet as proof that they have completed Leon's test. So, Naoki has earned another chance to fight Leon. Now knowing that passion alone not being enough, being adaptive, and experimenting were the lessons that Leon was trying to teach him and Kamui, Naoki uses a modified deck to push Leon close to defeat. Despite his best efforts, Leon still wins but compliments Naoki's perseverance as his strength and has now learned to take full advantage of it. (Source: Wikipedia)
