Third-year junior high schooler Manaka Mizusawa is tasked by her teacher to put up a poster about a trial ice hockey class sponsored by the Dream Monkeys, their city's local professional team. Interested in attending the class herself, she persuades her younger sister Ayaka and clubmates Kaoruko Yanagida and Mami Ono to join her. When the four gather at the gymnasium where the tutorial is held, they meet fellow third-year students Riko Saginuma and Naomi Takagi. As the girls practice hard, their fascination for the sport grows, motivating them to play on a competitive level. Wanting to experience unique and exciting memories that ice hockey can offer, the girls gradually form a team with potential to reach the top.
