Big eyelashes diva. Rin Itoshi (Blue Lock) es un futbolista frío, arrogante y obsesivo, motivado por un ego destructivo y una rivalidad distorsionada con su hermano Sae. The story of Sae and Rin Itoshi in *Blue Lock* is a tale of admiration and a fractured fraternal bond. After a trip to Europe, Sae abandons his dream of becoming the best striker and shatters the aspirations he once shared with his younger brother. This rejection transforms Rin’s admiration into deep-seated resentment and an obsession with surpassing Sae within the Blue Lock project. The rivalry between Rin and Isagi evolves from Isagi's initial admiration into a mutually destructive obsession. Isagi manages to match Rin's vision of the game, forcing him to evolve, but the definitive breaking point occurs after the match against the U-20 team. In that game, Isagi scores the winning goal and receives public praise from Sae, who ignores Rin. From then on, Rin becomes obsessed with destroying Isagi on the field, and the two emerge as the ultimate rivals for the throne of Blue Lock.
