Cold, solitary, and incredibly strong-willed. He possesses an arrogance that looks down on the Japanese soccer world as "finished" and spits harsh vitriol at the media. On the other hand, he has a stoic side, relentlessly pursuing his goal of becoming the world's best striker. His personality and character can be summarized as follows: Cold and Stoic: Extremely severe regarding his own goals, he allows no compromise when it comes to soccer. He is also harsh toward his younger brother, Rin, and a deep feud exists between them. Blunt and Vitriolic: He says exactly what is on his mind without caring about the opinions of those around him or public expectations. He has even told the media upon their first meeting that he has "no intention of playing in Japan" and would "rather die." Hidden Passion for Soccer: Usually expressionless and cool, he displays genius-level technique and tactical vision during play. He has never wavered from his childhood dream of becoming the world's best striker.

Usually cold and looks down on everyone around him as "lukewarm," but at his core, he hides an abnormal obsession with winning and a burning conviction to fight with everything he has.

Possesses an androgynous beauty and a frank, easygoing pace, while hiding a "genius passion for soccer" and a "hatred of losing" that is stronger than anyone else's. He is very knowledgeable about beauty and skincare.

Extremely lazy and moves at his own pace. The main characteristics of his personality are as follows: Extreme Laziness: From daily life to soccer practice, his catchphrase is "what a pain," and he hates moving of his own accord. Dependent and Spoiled: He is deeply dependent on Reo Mikage, who discovered his soccer talent, even in his private life, taking it for granted that he will be carried on Reo's back or taken care of. Cruel Honesty: While he harbors no malice toward others, he has a cruel side where he bluntly tells people he finds uninteresting or untalented that they are "trash" or "useless." Awakening Ego: Triggered by his meeting with and defeat by Yoichi Isagi, he begins to develop a strong obsession with "frustration" and "wanting to win" that he never had before, blossoming into an overwhelming egoism unique to geniuses.
