In pursuit of her dream as a singer, Hiyori Hayama moves to Tokyo, aiming to follow in her idol's footsteps on the stage. Despite her love for music, the harsh reality of the entertainment industry hits hard as she faces rejection in auditions and struggles to sell her songs. Feeling stuck at square one, Hiyori seizes a chance to advance by entering Extreme Hearts, a prestigious Hyper Sports competition where contestants use special gear to compete in various sports. While Hiyori lacks familiarity with this unique world, her athletic prowess is overshadowed by her inexperience. Luckily, she forges bonds with skilled girls in different sports, forming Team RISE to support her journey to the top. As they delve into the tournament, Hiyori and her teammates discover a crucial requirement—all participants must either be entertainers or aspire to become one. Embracing this rule, Team RISE dives into fierce competition, unearthing not only hidden talents but also enduring camaraderie that transcends the boundaries of sports and entertainment.
