S1·E19 The Card Yota Left Behind

After Genma defeats Zanya, the tournament is temporarily put on hold to repair the fight stadium. Gao and his friends meet at his home, and then Doai appears to deliver a message from Genma, telling Gao to withdraw from the upcoming match. Gao refuses to do so, which Doai expected, and before leaving, he warns Gao about Genma's Koryukien deck. Later, while Gao and his friends are having a dinner party, Suzumi reminisces about Gao's deceased older brother Yota and talks about how she wanted to keep Gao close to her. She then resolves her feelings and gives Gao a card that Yota left behind, which Gao decides to add to his deck. The next day, the final Buddyfight in the ABC Cup between Gao and Genma ensues.
