Nagi Seishiro

Height 190 cm, white hair, gray eyes. Nagi is an unnaturally talented soccer player with incredible reflexes, good speed, and jumping skills, but despite this, he initially doesn't want to put any effort into soccer, such as training, and belittles those who are weak and untalented in the game. He doesn't even know much about the best soccer players in the world, much to the chagrin of his competitors. He is initially shown to be indifferent to playing soccer and becoming a better striker, and would rather play video games or skip training.

However, after playing in a match against Team Z, Nagi begins to take initiative and tries to score goals on his own. This only happens because he notices that his teammate, Reo Mikage, seems to be losing to the opposing team. Despite his initially indifferent appearance, Nagi strives to improve his soccer skills as a result of his team's loss to Yoichi Isagi. This drive to improve follows him into later arcs, and he even tarnishes a friendship because of it.

Nagi seems to care about his friends and teammates, especially Reo Mikage, although their relationship becomes strained from the second selection onwards.
