Extreme Hearts

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.
