Extreme Hearts is an original Japanese anime television series created and written by Masaki Tsuzuki, the creator of Magical Girl Lyrical Nanoha and Dog Days, directed by Junji Nishimura and animated by Seven Arcs, which aired from July to September 2022.

In the near future, a trend in the sporting world is Hyper Sports, in which various sports are played with advanced equipment that enhance the player's abilities. One of the popular Hyper Sports leagues is Extreme Hearts, managed by a music company and composed of female idol groups across Japan.

After being released from her record label, failed artist Hiyori Hayama gets invited to join Extreme Hearts through her fan Saki Kodaka. Not wanting to give up on her music industry dreams yet and despite her inexperience with Hyper Sports, Hayama accepts the invitation and enlists the help of Kodaka and Sumika Maehara (later joined by Yukino Tachibana and Lise Kohinata). Together, they form the idol group RISE and their goal is to make it big in Extreme Hearts.
