The official website for Extreme Hearts, the new project from writer Masaki Tsuzuki, revealed the introduction of the project's story, main voice actors, more staff members, a fourth image, and the anime for the summer season.

Plot
The story takes place in the future, not long after the present day. Hypersports, which use extreme equipment as support items, have become popular hobby competitions among children and adults. Hiwa Hayama is a high school singer who has nothing to do with hypersports, but a certain incident sets the story in motion. “This is the story about how we met our greatest friends.”
Voice actors
- Ruriko Noguchi as Hiwa Hayama
- Kana Yuuki as Junka Maehara
- Miho Okasaki as Saki Kotaka
Junji Nishihara is directing the anime, while Issei Aragaki is designing the characters for animation, and Aragaki and Kana Hashidate are also serving as chief animation directors. Shuichi Kawakami and Takuya Fujima then wrote the designs for the secondary characters.
As previously announced, Tsuzuki is therefore credited for the original story and scripts, while Waki Ikawa is credited as the character 'designer'.
Finally, the already announced voice actors will appear in a stage event that will take place on the Blue Stage of AnimeJapan 2022 on March 27th. In addition, the event will then present more details about the anime and a promotional video.
