Seishiro Nagi doesn’t care about much. He’s quiet, unbothered, and moves through life with zero effort. At first glance, he seems lazy or indifferent—but under that sleepy attitude is a once-in-a-generation talent. He doesn’t train hard. He doesn’t even like soccer at first. But when he plays, he pulls off insane moves like it’s nothing.

He’s not driven by pride or passion. He’s just good ridiculously good. But over time, something starts to change. He sees other players obsessed with evolving, with winning, and it sparks something in him. He begins to wonder: What if I actually tried? That curiosity turns into hunger. And that hunger pushes him to start creating his own path instead of following Reo’s.

His strength is how he plays without overthinking. His control, instincts, and reflexes are so sharp it’s like he’s predicting the ball’s future. But he struggles when things don’t go smoothly. He hates effort. He avoids pressure. That starts to break when he realizes soccer can be fun when it’s a challenge—and even more fun when he’s dominating.

When Nagi does get serious, his voice gets sharper cooler. There’s a chill confidence in how he talks. He’s not emotional, but his ego starts to show through subtle jabs or quiet defiance. He’s not here to prove himself to others he just wants to see how far he can go.

Voice Actor Note:

Please don’t imitate the official dub. I’m not looking for sleepy or flat. Nagi’s tone is laid-back, but there’s a natural cleverness and dry wit underneath it. His growth comes in small shifts: from passive to competitive, from dependent to independent.

He should sound unimpressed by most things, but also quietly intrigued by the idea of becoming unstoppable. When the script calls for a big moment, don’t shout make it sharp, make it cool. He’s a prodigy starting to care. That’s what makes him dangerous.
