Field vision and game reading. Sae seems to "see" the game seconds ahead: he anticipates the movements of defenders and attackers, exploits space, and creates ideal scoring opportunities.
He is a member of the New Generation World XI, highlighting his recognition as one of the most promising young players in the world.

Additional facts
Position: attacking midfielder.
Team: Real Madrid youth team, also played for the Japan U-20 team.
Role in the plot: He becomes a kind of "standard" to which other players (including Rin and Isagi) aspire. His appearance in the matches against Blue Lock demonstrates the extreme level of professional football compared to the ambitions of the project's participants.
Surname and name: Itoshi (糸師) can be interpreted as "master of the string/game", and the name Sae (冴) carries the connotation of "clarity", "cold composure" - this reflects his playing style and character well.

Sae Itoshi is Rin Itoshi's older brother and one of the strongest soccer players in the world according to the Blue Lock universe. He is the epitome of professionalism and cold-blooded calculation on the field.

Appearance
Sae is a tall, slender, and athletic young man with a refined, almost icy aesthetic. He has light (almost white or ash-blond) hair, styled so that his bangs fall slightly over his face. His eyes are expressive, cool in color (often painted blue-gray or silver), highlighting his aloofness and insight. Overall, his appearance is that of a mature European footballer: reserved, collected, and without unnecessary details.

Character
Cool and calculating. Sae almost never loses his composure. He evaluates the game mathematically: he identifies his opponent's weaknesses, calculates options several moves ahead, and acts with maximum efficiency.
Ambition. He doesn't just want to win—he wants to be the best in the world in his position. His ambitions evolve, too: at first, he dreamed of becoming a top striker, but after playing in Europe, he decided his true place is as an attacking midfielder, where he can control the entire game.
Emotional restraint. Sae rarely displays his emotions openly, making him appear arrogant or indifferent. But behind this lies a deep devotion to football and a desire to elevate the level of play around him.
His attitude toward his brother. Despite his outward aloofness, he genuinely cares about Rin and, in a sense, pushes him to become stronger—albeit through fierce competition.

Name Etymology: The name Rin (凛) means "cool" or "dignified." The family name Itoshi (糸師) translates to "thread maker" or "string master," further emphasizing his playing style.
In the Blue Lock project he competes for the Paris X Gen team.
When in flow, his playing style becomes more aggressive and instinctive.
Rin Itoshi is a complex character, combining cold calculation with a deep passion for football and a constant drive to improve. His story is a journey from obsessively rivaling his brother to embracing other strong opponents and enjoying the game itself.

Appearance
Rin is a tall teenager (around 186–187 cm) with a slender yet muscular build. He has dark green hair, his bangs slightly covering his right eye. His eyes are turquoise, and he also has rather expressive eyelashes—a trait he inherited from his older brother, Sae Itoshi.

Character
At first glance, Rin appears cold, aloof, and even arrogant. He tends to dismiss other players' abilities, calling them "mediocre" or "weak." He's abrupt in his interactions, often using nicknames instead of names, and maintains aloofness.

But behind this mask lies a deep motivation. As a child, Rin sincerely admired his brother and wanted to be just as strong a footballer. After Sae left for Spain, Rin realized the game had become more difficult and resolved to surpass him at all costs. This obsession shaped his character: he became more calculating, goal-oriented, and at times self-centered, putting his own ambitions above those of others.

However, as the story progresses, Rin changes. His rivalry with Yoichi Isagi led him to see him not just as a nuisance, but as a worthy opponent. Gradually, Rin began to enjoy the challenge itself and his passion for the game.

What does he like?
Football. For Rin, it's not just a game, but almost an obsession—a way to prove his superiority.

Tuna with soy sauce and wasabi - considers it a winning combination.
Autumn - he likes cool weather.
