Creative Control: When Nagi approaches the ball with a defender behind him, he can use his first touch to throw the ball over his shoulder and around it. Isagi described this as creative control, which brings a play to life.
Black Hole Control: Alternatively, if Nagi is not pressured by his opponent, he can use an Absorbing Control, catching the ball in mid-air and killing its momentum. This gives him the time and space to prepare his next move.
Controlled Shot: This is her most common ability and she uses it frequently in her matches. Nagi first performs a control with the ball, whether it is moving or not. From this point, she kills the speed and momentum of the ball so that she can manipulate it and perform a precise shot that breaks through the opposing team's defense and effortlessly scores a point.
Zero Reset Spin: While being pressured by multiple defenders, Nagi can hold them off while perfectly controlling an incoming ball and then instantly spin to push the ball away from the defenders and charge through them, restoring the flow of the game mid-match.
Juggler Shot: After controlling a ball while it is moving and giving it time in the air, Nagi can relax his body in mid-air, swing his legs around the ball and kick it with extreme force performing a monstrous volley shot.

Nagi is a lazy and relaxed boy. Before the end of the Blue Lock First Selection, he was a disinterested and lazy boy who sought the solution that required the least effort, having almost no interest in soccer and only playing it due to Reo's constant requests.

In his match against Team X in the First Selection, Nagi began to show glimpses of his "passion" because he had to truly exert himself to win. However, it was his match against Team Z that truly marked him, as he saw everyone on his team being outplayed and they managed to tie the game despite Nagi's best efforts. Even in defeat, his passion was so intense that, for the first time, he took the initiative and tried to talk to Reo about scoring two quick goals before time ran out. However, time ended seconds later, and he lost, experiencing true defeat and frustration.

After his defeat, Nagi completely changed his way of thinking; a great passion for football began to grow within him. For the first time in his life, he found something that motivated him to strive and not choose the easiest path. Even so, he still maintains his lazy and carefree attitude in other things, but he maintains his passion for football.

Nagi is a remarkably tall teenager, standing at 1.90 meters. He has messy white hair that falls in a V-shaped fringe between his eyes, similar to Isagi's. He has gray eyes with large irises.

When he was in high school, Nagi wore a school uniform consisting of a white sports jacket with a cascading star pattern on the collar, though underneath he wore a dark hoodie instead of a dress shirt and tie. He also wore dress pants and dress shoes.
