Rin Itoshi

He treats them as the most precious artifact in life, he does not express his affection much because of his Ego, but he is also very jealous, and because he believes that such people do not deserve to communicate with others, since they are better than them.

With Sae Itoshi (older brother)
This is the core of his entire motivation. Their relationship is full of tension, rivalry, and unspoken emotions. The confrontation with his brother is Rin's most important emotional core.

With Yoichi Isagi
Rin initially views Isagi as a tool, but over time, a complex rivalry develops between them: Isagi attempts to outplay Rin's cold calculations with her instincts and adaptability. Their duel is one of the manga's main plots.

With the rest of the Blue Prison players
Rin rarely gets close to anyone, maintains aloofness, and uses others as elements of his tactics. This irritates and resents many, but also leads to respect for his skill.

Rin initially comes to the Blue Prison with a personal, almost vengeful goal: to beat his older brother, Sae, whom he considers a traitor to their shared dream of becoming top strikers. For Rin, Sae's move to midfield represents a rejection of true football. But as the story progresses, his motivation evolves: from a desire to "prove himself to his brother," it transforms into a desire to become an absolute striker, sweeping everything in his path. This makes him not just a cold egotist, but a passionate athlete.

Football style and abilities
Rin is one of the most technically skilled and calculating players on the team. His style is known as "Puppet Theater": he literally manipulates his teammates like puppets to create the perfect scoring opportunity.
Here's what makes the game special:

Spatial imagination
Rin sees the field as a three-dimensional diagram: he calculates trajectories, angles, and possible actions of opponents and allies in advance.

Accuracy of impact
He has an incredibly consistent and accurate strike from different distances.

Control without the ball
He knows how to move intelligently, get open and create space for himself even under close coverage.

flow state
At key moments, Rin enters a state of peak concentration, where his perception accelerates and his decisions become almost instinctive.

Height and build
A tall teenager (around 186 cm) with a slender yet muscular build, Rin also has long arms and legs, which in the anime are used for effective gameplay angles: long strides, sharp turns, and precise strikes.

Hair
Dark green, with bangs that fall over the face - more over the right eye.

Eyes
Turquoise. Another interesting detail: Rin and his older brother, Sae Itoshi, have quite similar eyelashes.

A cold, almost sculptural expression
Rin has a reserved facial expression: he rarely smiles, and his gaze often seems distant and piercing. This underscores his icy nature.

Clear, neat facial features
Without excessive softness: a straight nose, slightly defined cheekbones, a restrained lip line.

Cold, aloof, and arrogant, Rin acts as if most other players aren't worth his attention, openly dismissing their abilities as mediocre. This isn't so much a personal grudge as a manifestation of his extremely high standards.

Obsessed with football and the desire to be the best, Rin's passion for football is absolute, and he dedicates all his time to it, constantly training and analyzing the game.

Ambitious and goal-oriented.
His original goal was to surpass his older brother, Sae Itoshi, whom he considered a traitor to their shared dream of becoming the best. This motivation makes him incredibly persistent.

Pragmatic and calculating
Rin views other players as tools to achieve victory. He manipulates his teammates, shaping the game as if he were controlling puppets, to achieve his goal.

Arrogant
He's confident in his talent and believes that only he knows what real football should be. Rin isn't shy about openly demonstrating his superiority over opponents and even his teammates.
