Excited to pursue his latest passion, he gradually bonds with his new classmates—such as the talented Shun Kazanami and the self-assured Amane Grace—who are each unique in their own way. Although the path ahead may be full of obstacles, Yuu is determined to pursue his ultimate goal of becoming one with his horse.
