Rouga Aragami Attacks!.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.
