Assuming his identity as the top Buddyfighter in 8th grade at Aibo Academy, Rouga challenges Gao to a Buddyfight, but Gao refuses. Rouga slips on a banana peel set up by Tetsuya and Asmodai , which prompts him to challenge Tetsuya, which Asmodai accepts (without Tetsuya's consent). During lunch break, while Rouga and Tetsuya battle, Gao is reminded about a time when he also believed that winning was everything like Rouga. When Gao's hunger for winning led to him injuring someone during a martial arts match, he realized that mentality is wrong. Gao has since then changed in order to make more friends.
