In the heart of Japan, Kazemachi Sota was a high school football legend, the fastest and most skilled quarterback the Nishikawa Hawks had ever seen. But a devastating injury shattered his dreams, leaving him to navigate a new life of uncertainty. Labeled "the bird with clipped wings," Kazemachi struggles to find his place in a world without the sport that defines him. Just as hope seems lost, an unexpected invitation from a spirited girl named Aiko reignites his passion. She invites him to join the school’s flag football team, a game of strategy and speed, offering him a chance to redefine himself. Will Kazemachi find a new way to soar, or will the shadows of his past keep him grounded forever? This is a journey of self-discovery and triumph against all odds.

These events have led to humanity being hunted to near extinction by the United Galactic Senate, a powerful coalition of alien races committed to maintaining galactic peace and order.
