The story begins with Hiyori, an already debuted singer/songwriter with an extremely small following, and her kouhai, Saki. When Hiyori's contract is terminated, she sets her sights on Extreme Hearts, a knockout-style sports-festival for entertainers. The competition itself cycles through different sports, from baseball to basketball, and from soccer to rugby. Hiyori sets out to overcome these challenges, and with the help of her kouhai's friend, Sumika, prepares as best she can to face it. But she's alone, and the aforementioned sports are all team-based sports. Without the help of her friends, she won't get very far.
This series is never about the sports; the sport is the challenge. And it's not about having the most unique storyline. Nor the most realistic. In fact, it's filled with tropes. And the Sci-Fi elements are barely explained. If that grinds your gears, then you'll end up hating this series. But if you're okay with that and you're not heavily leaning into sports or idols, then you'll find a series that overflows with warm feelings and extreme positivity. It's refreshing and wholesome. This applies even between direct competitors in the sports festival. The various groups come together, help each other practice, and lift each other to new heights. It's wonderful and a gentle take on what life is all about.
I can easily draw comparisons between this series and Iwa Kakeru or Dog Days. If you liked those, you'll like this.
