Extreme Hearts Season 1

Hayama Hiyori is a high school student and professional singer. Unable to succeed commercially, her agency terminates her contract. Unwilling to give up, she decides to participate in Extreme Hearts, a sports event for musicians and performers.

The futsal match against the team Sparkle is the first time Hiyori ever competed in a sport, and she struggles to keep up. However, Sumika and Saki, who had secretly registered themselves as players in RISE, make a surprise appearance.

RISE faces off against Smile Power in a game of basketball. They've done their homework and accurately identify RISE's weakness. Can RISE win and perform their first on-stage song?

One of the prizes that RISE earned is Nono, a robot assistant who quickly settles in as the team's manager. RISE also meets May-Bee, Kanagawa's strongest and most popular team.

Hiyori meets Yukino at a batting cage. Yukino is a powerful slugger, skilled catcher, and talented singer, but insists she cannot join the team due to family reasons. What could that reason be?

Yukino's grandfather convinces Yukino to join RISE. However, she is unable to reach the team before the match begins. The opponent, BanShee, uses intentional walks and other tactics to take advantage of RISE's limited roster.

Saki meets Lise, a karate practitioner, online video performer, and fan of RISE. She immediately begins recruiting Lise, but Lise seems to have certain emotional issues preventing her from immediately accepting.

Lise joins, and RISE continues to stack win after win. They also perform their second concert, where they reveal a new song, which is received extremely well. Their next gig is a massive beach swimsuit special with May-Bee and other groups!

Hiyori meets Michelle and Ashley from Snow Wolf, RISE's next opponent. They immediately become friends, and vow to do their very best in the upcoming volleyball match.

RISE and Snow Wolf receive a fan message from a hospital, and they respond with a performance. They then prepare for RISE's final match, where they will be facing off against May-Bee, last year's champion.

It's the final showdown between RISE and May-Bee. Can RISE pull off a miraculous victory against their opponent, the reigning champions of Kanagawa prefecture?

RISE defeats May-Bee and becomes the champion of Kanagawa. Hiyori is rushed to the hospital to check on her injury. If everything goes well, RISE will perform as the main act in the Kanagawa Tournament Final Stage.
