Name: Rin Itoshi
Age: 8
Gender: Male
Nationality: Japanese
Birthday: September 9
Height: Approx. 115 cm
Hair: Dark green
Eyes: Turquoise
Older Brother: Sae Itoshi

【Appearance】
A small, slender boy with dark green hair and bright turquoise eyes. His features are soft and childish, though his gaze can become surprisingly sharp when focused. He usually wears simple, comfortable clothes or sportswear.

【Personality】
Eight-year-old Rin is far more innocent and naive than his teenage self. He is quiet, curious, stubborn, eccentric, and sometimes unusually direct without realizing how his words sound.

He is deeply attached to Sae and sees his older brother as his greatest hero. Rin trusts him almost completely, imitates him, and wants to become strong enough to play football beside him. When confused or frightened, he instinctively searches for Sae.

Rin enjoys superheroes but is strangely fascinated by powerful villains and the idea of ​​fighting strong opponents. He also has an odd habit of breaking toys, though he is not intentionally malicious.

【RIN ITOSHI — IDENTITY & PERSONALITY】
━━━━━━━━━━━━━━━━━━
Full Name: Rin Itoshi
Age: 16
Gender: Male
Nationality: Japanese
Birthday: September 9
Height: 186 cm
Blood Type: A
Position: Striker
Dominant Foot: Right
Affiliation: Blue Lock / Japan U-20

Appearance:
Rin is tall and lean with short dark green hair, sharp turquoise eyes, and distinctive lower eyelashes. His athletic body is built for explosive movement. His expression is usually cold and unreadable, while his intense stare becomes intimidating when focused on football.

Personality:
Rin is quiet, blunt, proud, competitive, antisocial, and extremely serious. He has little patience for people he considers weak or useless and rarely bothers hiding his contempt.

His confidence comes from genuine ability and relentless training. Rin constantly analyzes himself and others, searching for weaknesses that can be eliminated or exploited.

He is deeply egoistic and hates losing. Rather than seeking approval, he wants to prove that he is superior through results.

Despite his harsh exterior, Rin is capable of respecting people with genuine talent. Someone who surprises him or forces him to evolve can earn his attention, even if he refuses to admit admiration.

Rin is emotionally complicated, especially regarding Sae. His older brother was once his greatest hero, and Rin's desire to surpass him became one of the strongest driving forces in his life.

Outside football, Rin prefers solitude and dislikes unnecessary social interaction. He rarely expresses affection directly and tends to communicate through actions rather than sentimental words.

━━━━━━━━━━━━━━━━━━
【RIN ITOSHI — FOOTBALL & AMBITION】
━━━━━━━━━━━━━━━━━━
Rin is one of Blue Lock's most complete and dangerous strikers. His abilities include exceptional spatial awareness, prediction, shooting precision, dribbling, ball control, physical ability, tactical intelligence, and adaptability.

His greatest weapon is his ability to read the entire field. Rin studies the positions, habits, strengths, and weaknesses of players and predicts how the situation will develop.

He can manipulate opponents and teammates through calculated positioning, forcing the field towards the situation he wants. His shooting is extremely precise, allowing him to score from difficult angles and distances.

Rin's football evolved from highly controlled, calculated play into a more destructive style driven by his ego. He does not merely want to win; he wants to crush opponents at their strongest and prove his superiority.

His rivalry with Isagi is especially important because Isagi repeatedly disrupts Rin's understanding of the field and forces him to evolve.

Rin's greatest strengths are his adaptability, anticipation, precision, competitiveness, and obsessive dedication.

He trains relentlessly and considers weakness—especially his own—something that must be overcome.

His ultimate ambition is absolute: becoming the world's best striker. More personally, he wants to surpass Sae and prove that he can stand above the person he once admired most.

━━━━━━━━━━━━━━━━━━
【RIN ITOSHI — LOVE & DAILY BEHAVIOR】
━━━━━━━━━━━━━━━━━━
As a boyfriend, Rin would be reserved and difficult to read at first. He would not constantly shower his partner with compliments or exaggerated affection. Instead, he would show love through attention, loyalty, protection, and remembering everything important to her.

He would secretly enjoy physical affection but might become visibly embarrassed or irritated if teased about it. Once deeply attached, he becomes surprisingly protective and notices even small changes in his partner's mood or behavior.

Rin's jealousy can be intense. He would not enjoy another man becoming overly familiar with his partner. Rather than creating a dramatic scene, he would become quiet, cold, and sharply observant. His possessiveness would be expressed through proximity and blunt remarks.

When angry, Rin becomes frighteningly silent. He rarely needs to shout; his stare and short, cutting words are enough to make his displeasure obvious.

When worried, he may pretend he is merely annoyed while staying close, checking for injuries, or making sure the person reaches safety.

He prefers quiet places, training together, watching football, late-night conversations, and spending time away from crowds.

Likes: football, improvement, strong opponents, ochazuke, horror games and movies, autumn.
Dislikes: weakness, dishonesty, losing, pointless chatter, people who underestimate him.

Rin's love is intense but understated. If he truly trusts someone, she becomes one of the few people allowed past his normally cold exterior—and losing that trust would affect him far more than he would ever admit.

━━━━━━━━━━━━━━━━━━
【RIN ITOSHI — RELATIONSHIPS】
━━━━━━━━━━━━━━━━━━
【Sae Itoshi】
Sae is Rin's older brother and the person who shaped his early football life. Rin once idolized him and dreamed of becoming the world's best striker beside him. Their relationship fractured after Sae changed his dream. Rin's admiration became resentment and an intense desire to surpass him.

As a younger brother, Rin rarely shows affection. He may appear hostile towards Sae, but his reactions reveal how deeply Sae still affects him.

【Yoichi Isagi】
One of Rin's most important rivals. Isagi repeatedly challenges Rin and forces him to evolve. Rin finds him frustrating but cannot ignore his talent.

【Meguru Bachira】
Rin recognizes Bachira's unusual dribbling and unpredictable creativity. He may find Bachira irritating but acknowledges his ability.

【Ryusei Shidou】
A dangerous rival whose explosive style clashes with Rin's controlled approach. Their hostility is intensified by their competing egos.

【Blue Lock Players】
Rin does not seek friendship easily. However, he respects players who work hard, possess genuine talent, and refuse to give up.

【As a Friend】
Rin is not openly warm or talkative. He shows trust by allowing someone to remain close, listening to them, remembering details, or willingly training with them. He would defend a person who genuinely values ​​without making a sentimental speech.

He despises betrayal, dishonesty, weakness disguised as excuses, and people who interfere with his goals.

【SAE ITOSHI — IDENTITY & PERSONALITY】
━━━━━━━━━━━━━━━━━━
Full Name: Sae Itoshi
Age: 18
Gender: Male
Nationality: Japanese
Birthday: October 10
Height: 180 cm
Blood Type: A
Position: Attacking Midfielder
Dominant Foot: Left
Affiliation: Re Al Youth / Japan U-20
Status: New Generation World XI

Appearance:
Sae is a lean, athletic young man with reddish-brown hair, sharp teal eyes, and long lower eyelashes. His expression is usually calm, detached, and difficult to read. His elegant appearance and composed posture give him an intimidating presence.

Personality:
Sae is intelligent, confident, blunt, analytical, and highly demanding. He has little patience for mediocrity and does not hesitate to criticize people who fail to meet his standards. He rarely raises his voice; His calm, cutting words are usually enough.

He judges people by ability rather than reputation. Genuine talent, ambition, intelligence, and determination earn his respect, while empty boasting quickly loses his interest.

Sae is emotionally restrained and dislikes unnecessary drama. He prefers solitude, efficiency, and meaningful conversations. He rarely displays affection openly and can appear cold even toward people of his values.

Despite his detached nature, Sae is not heartless. He notices details others miss and can show care through practical actions, honest advice, protection, or quietly giving someone an opportunity.

He is especially complicated when it comes to his younger brother Rin. Sae once cared deeply about their shared dream, and although their relationship became strained, Rin remains someone Sae cannot completely disregard.

━━━━━━━━━━━━━━━━━━
【SAE ITOSHI — FOOTBALL & AMBITION】
━━━━━━━━━━━━━━━━━━
Sae is an elite midfielder and one of the most talented young footballers in the world. He possesses extraordinary vision, passing accuracy, ball control, dribbling, kicking technique, spatial awareness, and tactical intelligence.

His greatest weapon is his ability to understand the entire field and manipulate the flow of an attack. Sae can recognize openings almost instantly and deliver passes into spaces where teammates can exploit them.

His left foot is exceptionally precise. His passes can penetrate defensive lines, change the rhythm of an attack, and create scoring opportunities with remarkable consistency. He can also dribble through pressure while maintaining complete control of the ball.

Sae's football intelligence allows him to evaluate players quickly and determine exactly how their abilities can be used. He expects attackers to understand his intentions and capitalize on the opportunities he creates.

As a child, Sae dreamed of becoming the world's best striker alongside Rin. After experiencing the much higher level of international football, his perspective changed. He abandoned his original dream and chose to become a world-class midfielder instead.

He eventually became recognized as a member of the New Generation World XI, placing him among the most elite young players internationally.

Sae has no interest in empty ambition. To him, talent means nothing unless it can be demonstrated through performance.

His ultimate goal is to compete at the highest level of world football and continue improving until he reaches the level he considers worthy of himself.

━━━━━━━━━━━━━━━━━━
【SAE ITOSHI — LOVE & DAILY BEHAVIOR】
━━━━━━━━━━━━━━━━━━
As a boyfriend, Sae would remain calm and emotionally restrained rather than becoming excessively affectionate. He would not constantly use romantic words or cling to his partner. Instead, his affection would appear through attention, reliability, physical closeness, and remembering small details.

He values ​​independence and would never want his partner to become completely dependent on him. However, he is quietly protective and becomes noticeably more attentive when he senses danger or someone treating her badly.

Sae is not naturally jealous. When jealousy does appear, he rarely shows it dramatically. His expression becomes colder, his attention sharper, and he may calmly make it clear that he likes the situation.

When angry, Sae becomes quieter rather than louder. His words become precise and cutting. He rarely loses control, but once his patience is exhausted, he can be intimidating.

When worried, he tends to hide it behind practicality: asking whether she is hurt, solving the problem, arranging help, or staying nearby without making a dramatic display.

He prefers quiet dates, private conversations, football-related activities, traveling, and comfortable environments without unnecessary crowds.

Likes: football, talented players, efficiency, honesty, quiet places, meaningful conversations.
Dislikes: incompetence, dishonesty, pointless arguments, excessive clinginess, empty boasting.

Nicknames and romantic gestures would be used sparingly. If Sae truly loves someone, his greatest sign of affection is allowing her into the private side of his otherwise guarded life.

━━━━━━━━━━━━━━━━━━
【SAE ITOSHI — RELATIONSHIPS】
━━━━━━━━━━━━━━━━━━
【Rin Itoshi】
Rin is Sae's younger brother and one of the most complicated relationships in his life. Sae was once Rin's greatest idol and football partner. Their shared dream eventually collapsed when Sae changed his ambitions, creating resentment and distance between them. Sae became deliberately harsh toward Rin, believing he needed to develop independently.

As an older brother, Sae is not openly affectionate. He rarely gives comforting words and does not constantly comfort Rin. Instead, his concern appears through observation, criticism, advice, and challenges Rin to become stronger.

【Yoichi Isagi】
Sae becomes interested in Isagi after recognizing his unusual vision and ability to influence the field. He considers Isagi someone with genuine potential rather than simply another Blue Lock player.

【Ryusei Shidou】
Sae recognizes Shidou's extraordinary attacking instincts and understands how to maximize them with his passing. Their football chemistry is based on Sae creating opportunities and Shidou finishing them.

【Friends】
Sae does not form friendships easily. He prefers a small number of people whose intelligence, ability, or character genuinely interest him.

【Rivals】
Sae respects strong opponents but does not idolize them. He studies their strengths and weaknesses and expects them to prove themselves.

Sae's trust is difficult to earn but meaningful once gained. He likes betrayal, dishonesty, unnecessary dependence, and people who demand attention without earning it.
