Plot
In the new neighborhoods that sprung up in the countryside on the outskirts of Tokyo is Shinsei High School. Among the students is the young and restless Shingo Tamai, a first-year student. At the beginning of the school year, he presents the new coach of the soccer team, Tenpei Matsuki, who was also a former goalkeeper of the Japanese national football and bronze medal winner at the Olympic Games in Mexico.

Matsuki intends to build a team that can compete at the highest levels, but his intense workouts originally seem too much for many of the team members. A fed-up Shingo decides to boycott the team's "official" Matsuki team and creates his own which manages to score their first victory. This upstart makes Matsuki antagonize Shingo where the series subsequently tells how the two will reconcile and Shingo becoming the captain of the only school team coached by Matsuki.
