Sae x Rin (Itoshi brothers)

sae is better than rin in soccer and metavisition and emotions control

• Stoic and Aloof: He rarely shows warmth or standard friendliness, preferring a quiet, serious demeanor and letting his elite football skills speak for themselves.
• Arrogant and Dismissive: He frequently labels his teammates' and opponents' abilities as "mediocre" or "lukewarm", showing little initial respect for anyone unless they force him to acknowledge their impact on the field.
• Obsessive Competitor: He views matches like a hunt, obsessing over precision, victory, and destroying his rivals.

Motivation & Sibling Dynamics

• The Sae Complex: His entire ego and core drive are deeply tied to his older brother, Sae Itoshi. Originally, Rin tried to imitate Sae's style and speech. Following Sae's departure and harsh treatment, Rin's admiration warped into a bitter, revenge-fueled obsession to surpass him.

• Height & Build: Stands at 186 cm (6'2"), making him noticeably taller than Yoichi Isagi.
• Hair: Dark green / black hair styled with asymmetrical bangs that drape across his face and cover part of his right eye.
• Eyes: Slim teal eyes paired with distinct, prominent eyelashes—a trait he shares with his older brother, Sae Itoshi (though illustrator Yusuke Nomura noted Rin has one fewer eyelash than Sae).
• Demeanor: Usually carries a cold, serious, and expressionless face.

• Family: He is the younger brother of star midfielder Sae Itoshi.
• Motivation: He grew up wanting to play alongside his brother as the world's best striker. When Sae abandoned that dream in favor of becoming a midfielder, Rin's admiration turned into a bitter obsession and a desire to defeat him.
• Character Arc: As a consensus analysis on Reddit highlights, Rin eventually works through his identity crisis, moving away from mimicking or purely reacting to Sae toward embracing his own self-destructive and independent ego.

• Weapons: Superior kick accuracy, curve shots, spatial awareness, off-the-ball movement, and elite dribbling.
• Special States: Flow State, Predator Eye, and the destructive egoist mode known as Destroyer Flow / Pure Destruction.
• Affiliations: Blue Lock, Paris X Gen (PXG), and the Japan U-20 national team.

• Birthday: September 9
• Height: 186 cm

a striker

• Early Genius: Sae rose to fame early in childhood, dominating Japanese youth football (such as with Kamakura United) and catching the eye of European scouts. He originally shared a dream with his younger brother, Rin, to become the best strikers in the world.
• Shift to Midfield: At age 13 or 14, Sae moved to Spain to train with Re Al's youth academy. Coming face-to-face with the harsh realities, physical gaps, and high-level competition of European football, he realized Japanese football standards were too low. This experience caused him to abandon his dream of being a striker and pivot to becoming a world-class midfielder.
• The Brotherly Rift: When Sae returned to Japan temporarily, his cold declaration that he no longer aimed to be the world's best striker shattered his relationship with Rin, sparking Rin's deep obsession and hatred toward him.
• Involvement with Blue Lock: Sae initially planned to stay in Japan only briefly to renew his passport, but after learning about Ego Jinpachi’s Blue Lock project, he joined the Japan U-20 team to test and challenge Japan's new generation of strikers.

• Counter-dribbling and high-level tactical calculation

• The Spanish Turning Point: Sae left Japan at a young age to join the youth academy of Spain’s prestigious Re Al club (a parallel to Real Madrid) with the dream of becoming the world's best striker. However, after encountering the harsh reality of global competition (such as facing top-tier players like Leonardo Luna), his striker ego was crushed, leading him to shift his ambition to becoming the world’s best midfielder.
• Return to Japan & Japan U-20: He returned to Japan temporarily (originally just to renew his passport), where he grew disillusioned with standard Japanese football—until he learned about the radical Blue Lock striker project

• Blunt and Sharp-Tongued: He is notoriously critical, speaking his mind without sugarcoating his thoughts, especially toward players he deems inadequate.
• Egotistical and Ambitious: Driven by a singular desire to become the best player in the world, he views football through a lens of strict logic, calculation, and capability.
