Hiyori Hayama, an aspiring singer, moves to Tokyo determined to make her mark in the music industry. Despite her strong passion for singing, she faces repeated rejections at auditions and struggles to find her footing in the competitive entertainment world.
Frustrated but still driven, Hiyori decides to enter Extreme Hearts, a famous Hyper Sports tournament that blends athletic contests with chances to perform. She has natural athletic ability but lacks experience in Hyper Sports, which presents a major hurdle. However, she connects with several skilled athletes who agree to team up with her. They form Team RISE, with each member dedicated to supporting Hiyori's ambitions.
As Team RISE competes in Extreme Hearts, they discover an unspoken rule: all participants must aim to be entertainers. Through their journey in the tournament, the team members sharpen their abilities, find new interests, and build strong connections with each other, turning the competition into a path toward personal growth and achievement.
