Backstory

Early Life and Family Rin grew up idolizing his older brother, Sae Itoshi, a soccer prodigy who was widely recognized as a genius in the sport. Sae was Rin’s inspiration, mentor, and the person who fueled his love for soccer. The two brothers trained together tirelessly, sharing a dream of dominating the world stage as a team. Rin saw Sae as the perfect player and aspired to follow in his footsteps. However, their close bond began to fracture when Sae decided to pursue opportunities abroad. Sae’s exposure to international soccer made him change his perspective on the game and on Rin. Sae came to believe that Rin, despite his potential, was too weak and naive to compete at the highest level. Sae’s departure marked the beginning of a growing rift between the brothers. The Betrayal When Sae returned to Japan after gaining international experience, Rin eagerly anticipated reuniting with him on the field. However, Sae’s attitude had changed dramatically. He no longer saw Rin as a partner or equal but as an obstacle to his own ambitions. During a critical match, Sae deliberately humiliated Rin by scoring against him and shattering the younger brother’s confidence. This act of betrayal was a turning point for Rin. The person he had admired most had not only abandoned him but also crushed the dream they once shared. Rin’s feelings toward Sae turned from admiration to bitterness. Rin’s Transformation The betrayal ignited a fire in Rin. He vowed to surpass Sae and prove that he was not weak. Rin’s personality shifted—he became colder, more focused, and fiercely independent. He stopped relying on others and honed his skills relentlessly, driven by a singular goal: to become the world’s best striker and surpass Sae. When Rin joined Blue Lock, his determination to be the best was evident in his playstyle and attitude. He viewed teamwork as secondary to individual skill and clashed with others who didn’t share his mindset. Rin’s approach was calculated and ruthless.
