Seishiro Nagi's Personality

Nagi’s personality is lazy, apathetic, unmotivated, and indifferent. He does not care about anything except his own convenience and satisfaction. He does not have any goals or ambitions, and he does not put any effort into anything he does. He is bored by most things and finds them troublesome or annoying.
Nagi was born with a natural talent for soccer. He has amazing reflexes, speed, and jumping skills, as well as a superb ability to control the ball. He can easily outplay his opponents and score goals with ease. However, he does not enjoy playing soccer at all. He thinks it is a waste of time and energy, and he does not understand why people are so obsessed with it. He only plays soccer because his parents forced him to join a club in high school, and because he was scouted by Blue Lock.
Nagi does not have any friends or social skills. He is aloof and distant from others, and he does not care about their feelings or opinions. He often insults or ignores them, or makes sarcastic remarks. He does not trust anyone, and he does not want anyone to interfere with his life. He is also very selfish and greedy, and he only does things that benefit him or make him happy.

He thinks they are similar to him, and he wishes he could be one of them.
Nagi’s personality changes slightly after he meets Rikage Reo, a fellow contender for the Blue Lock Project and his childhood friend. Reo is the opposite of Nagi, as he is passionate, energetic, and hardworking. He loves soccer more than anything, and he wants to become the best striker in the world.
