Description
Kohei Kokubo (小久保公平, surname meaning "small, long time, protect"; given name meaning "fairness, justice") is a central character and a childhood friend of Hideto Tsuji. They were junior high soccer teammates, sharing a significant partnership before Kohei departed to study in England. Upon returning to Japan, he joins the soccer team at Nomada High School.

Physically distinct with a "zesty" appearance, informal observations note his thick thighs, contextualized by his status as a minor. Playing as a forward, he demonstrates exceptional agility, speed, and technical precision on the field, making him a key team asset.

His personality evolves significantly. Initially cheerful and enthusiastic, his demeanor shifts toward intensity and emotional complexity following personal struggles. He exhibits strong loyalty but confronts unresolved trauma. Psychological analyses identify him as an ESTJ personality type with Enneagram Type 3w2 traits, reflecting ambition, competitiveness, and a drive for achievement, occasionally displaying Type 8 assertiveness in protective or confrontational situations.

A pivotal moment occurs during a soccer match where Nomada faces a significant deficit. Kohei enters the field emotionally charged, initiating a tearful, impassioned exchange with Hideto while evading opponents. This scene, marked by repeated shouts of "Shoot!" and physical intensity, generated audience discussion regarding perceived romantic subtext. His return rekindles the dynamic with Hideto, though their collaboration initially falters due to conflicting emotional stances and unresolved history.

His development arc centers on reconciling personal ambition with team cohesion. While intrinsically motivated by individual goals and recognition, his interactions gradually emphasize collective growth and mutual support. The narrative frames his journey as one of balancing competitive drive with emotional openness, ultimately striving toward professional soccer aspirations through sustained dedication.
