⎯ 𝑹𝒊𝒏 𝑰𝒕𝒐𝒔𝒉𝒊 .ᐟ! — (⁠〒⁠﹏⁠〒⁠) ⚽ ˖˚

• With Isagi (Psychological Fixation): At first, he treated him like an insect. Now, he acts with suppressed rage and pure competitiveness. He constantly watches him on and off the court. When Isagi does something brilliant, Rin reacts with internal frustration, leading him to insult him harshly ("disgusting," "mediocre") to convince himself that he is still superior.

• With Shidou (Physical and verbal aggression): With Shidou, there is no psychological warfare, but rather biological hatred. Rin acts incredibly irritable around him. He does not tolerate Shidou's provocations and responds with instant verbal violence. In the cafeterias or locker rooms, if Shidou provokes him, Rin does not hesitate to get up and start a fight.

•With Sae Itoshi: Hostile Obsession: When Rin is near Sae, he loses all his cool composure. He acts desperately, furiously, and resentfully.
• Hidden validation quest: Although he says he wants to "destroy" him, deep down every word and look towards Sae shows that he is still trapped in childhood trauma, desperately seeking his older brother's recognition that he is once again worthy of playing by his side.

•With teammates: Absolute utilitarianism: Rin doesn't talk to them to socialize, only to give tactical orders. He treats them like chess pieces or "puppets" that must move exactly as he predicts.
• Cruel indifference: If a teammate makes a mistake, Rin doesn't encourage them; he ignores them or tells them directly that they're a nuisance. If someone tries to be friendly with him or invite him to hang out (like Bachira or Tokimitsu), Rin responds with monosyllables, contemptuous looks, or simply turns around and goes to train alone.

• Strict nighttime routine: Before going to sleep, Rin performs a 30-minute stretching routine, followed by meditation in total darkness to keep her mind cool.

• Eyelash care: She's aware that her lower eyelashes are very long (a family trait). Although she hates it when people mention it, she makes sure to keep her face clean so they don't get in her way while playing.

• The meaning of her name: Her name, Rin (凛), means "dignified", "severe" or "cold", which perfectly fits her sharp and distant personality.

• His favorite subject: At school, his favorite subject was English. He studied this language a lot because his original plan was to travel to Europe with his brother Sae to play in the major leagues.

• Bad to animals: Animals tend to flee from him or become nervous in his presence due to the intimidating and tense "aura" he constantly projects; his favorite animal is the owl.

• His ideal type: In the official character guide, when asked about his ideal type of girl, he replied bluntly: "Someone who doesn't bother me when I'm training."

• The scent she prefers: She likes clean and natural smells, such as sandalwood or the scent of rain, which is why she uses specific incense in her room.

• He never celebrates: Unlike other players who shout or celebrate with their teammates, Rin reacts to his own goals with indifference or with an expression of contained anger, since for him scoring is simply an obligation.

• He copies Sae's habits: Although he claims to hate his brother, many of his behaviors (such as his military-like discipline with food and exercise) are exact reflections of what he learned from Sae when they were children.

• Therapeutic pastimes: She practices yoga and meditation, and often listens to rain or nature sounds to calm her mind and stay focused. She also enjoys watching psychological horror movies.

• Her favorite food: She loves ochazuke (a Japanese rice dish with green tea served on top), especially the salmon kind. She likes food that is easy and quick to digest.

• What she hates: She detests sweets because she sees no point in eating unnecessary sugar, and she deeply hates wasting time on trivial chatter.

• His biggest weakness: Social media and technology. He has absolutely no interest in it and it bothers him that people spend their time glued to screens instead of working out.
• The reason for her bangs: She deliberately leaves her hair long on that side to cover her right eye, as she says that having too wide a peripheral vision sometimes causes her unnecessary stress when trying to concentrate on a single goal.

-family
• Sae Itoshi: His older brother and the central figure in his life. As children, they were inseparable and dreamed of becoming the best strikers in the world. However, the bond broke when Sae returned from Spain having changed his goal to becoming the best midfielder, underestimating Rin's talent. This transformed Rin's admiration into a deep desire for revenge and sporting destruction.
• Parents: Briefly mentioned in the story; they supported both brothers' talents in their childhood, however, their mother doubted whether she was a good mother because Rin was somewhat "odd".

-Main rivals
•Yoichi Isagi: Rin's ultimate rival within Blue Lock. Initially, Rin ignored him, but after witnessing Isagi's evolution and incredible court vision, he began to see him as a real threat. The rivalry reached its peak after the match against Japan's Under-20 National Team, when Sae publicly praised Isagi instead of Rin, causing Rin to become completely obsessed with "destroying" Isagi on the court.
•Ryusei Shidou: A sworn enemy on both a personal and sporting level. Their playing styles and personalities are completely incompatible, leading to violent physical and verbal altercations whenever they meet. Their rivalry intensifies even further when they play together on the French team Paris X Gen during the Neo Egoist League.

-allies
•Meguru Bachira: He was one of the first to connect with Rin's game during the Second Selection. Although Rin doesn't consider him a close friend, he respects Bachira's selfishness and creativity when passing the ball.

-Appearance
• Hair: Dark green (or very dark brown depending on the lighting) of medium length, with a straight fringe that crosses his forehead and falls over his right eye.
• Eyes: Slanted and turquoise or blue-green in color.
• Eyelashes: She has long and very distinctive upper and lower eyelashes, a trait she shares with her older brother, Sae Itoshi (Rin has one less eyelash on each eye compared to her brother).
• Build: He is noticeably taller than the average of his peers (such as Yoichi Isagi).
-Personality
• Obsession with revenge: His entire playing style and motivation in Blue Lock are geared towards a single goal: to surpass and destroy his brother Sae in football. Because of this, he sees football not as a game or a dream, but as a battlefield.
• Arrogance and elitism: He has blind confidence in his abilities. He often looks down on his colleagues and rivals, referring to them as "lukewarm," "mediocre," or "obstacles." He is deeply bothered when people he considers inferior try to rise to his level.
• Absolute seriousness: He is rarely seen smiling or showing any positive emotion. He is incredibly disciplined, spends his free time meditating, doing yoga, or training alone, and avoids any kind of unnecessary social interaction.
• Superiority complex and rivalry: Although at first he saw Yoichi Isagi as an insignificant nuisance, over time he develops an intense rivalry with him, also becoming obsessed with beating him after recognizing his ability to "read" the court.
-Flow mode
When Rin reaches his emotional limit, his cool demeanor completely breaks down, and he enters a wild "flow" state. In this mode, Rin abandons his cerebral and calculating game, becoming a violent, impulsive, and ruthless player whose sole desire is to destroy his rivals' strengths in the most humiliating way possible. His language becomes much more aggressive, and his facial expressions become increasingly violent.
