Known for his unpredictable moves and self-centered playing style, Ashito is the sole powerhouse pushing his team through an important high school preliminary tournament.

Just as he believes all hope is lost, Ashito is approached by a youth team coach named Tatsuya Fukuda who senses potential in him, and Fukuda invites him for tryouts in Tokyo. In an unfamiliar setting surrounded by talent, Ashito must bring out the best of his ability to prove himself and secure what could be a life-changing career.

Possessing a firm ambition, he begins to gain experience with the proper guidance of a coach—all in hopes of surpassing Yusa one day.
