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).

Junji Nishimura is directing the anime at Seven Arcs, with Tsuzuki writing the scripts, and Effy composing the music.

Aragaki and Kana Hashidate are serving as chief animation directors, and Shuichi Kawakami and Takuya Fujima drafted the sub-character designs.
