Rin Itoshi/Relationships

## Family

### Sae Itoshi

Sae is his genius and just as arrogant older brother. Sae is regarded as a genius and monster in the professional world despite being a few years older than him. They used to be quite close with each other in their childhood. Sae was admired by Rin and he was the reason Rin started to play football. Sae and Rin used to play together and won many games together, they even made a promise to become the two best strikers in the world. However, they got separated when Sae was scouted to play in the inferiors of the Real Madrid. Four years later, Sae and Rin met again while the last one was training late. Sae then tells him that he will become the best midfielder instead of the best striker of the world, thing that greatly affected Rin since his reason to play football had been his older brother. Sae then challenges Rin to play a 1vs1 and tells him that if he defeats him he will retake that dream with Rin. Sae utterly defeats Rin and says he feels disgusted with him and the football of Japan, also telling Rin to never use him as a reason to play football ever again, leaving his younger brother behind while he stays in the field shocked and later at his home swears to destroy Sae.

As a result, Rin became highly and sometimes scarily motivated to defeat his brother in football. He claims that they are not on bad terms but the mere thought and mention of Sae seems to highly upset the usually calm and collected Rin. They haven't seen each other in years, not till the match between Japan U-20 and Blue Lock Eleven. Sae is absolutely indifferent to Rin and doesn't speak to him until they have a 1vs1 in which Sae tells him that he will never be able to defeat him as long as he keeps considering himself as "Sae Itoshi's younger brother". And while Rin tries his best to prove that he is better than his brother, Sae doesn't pay him attention. Even after finally besting him in a 1vs1 match, their relationship fell virtually beyond repair when Sae acknowledged Rin's teammate and rival, Yoichi Isagi's skills instead of his own.

## Players

### Yoichi Isagi

Isagi claims Rin is his rival and the person he wants to surpass. Rin said that Isagi is nothing to him, although it is implied that they're at least competitive. Following Blue Lock's win against U-20 Japan brought by Isagi, Rin grew a huge resentment toward Isagi for stealing not only the final goal but also Sae Itoshi's acknowledgment as a true striker (something he craved more than anything else). Rin claming that he will "kill" Isagi, thus making him his primary target, **his rival.** Throughout the Neo Egoist League, his singular focus was to get stronger so he may finally "kill" Isagi once and for all in the final selection's final match.

### Ryusei Shidou

Rin has an antagonistic relationship with Ryusei. Despite having nearly the same superior football skills and techniques, Rin and Ryusei can be described as polar opposites and it is extremely difficult for them to play on the same team since they both are top players and egotists who have different approaches to the game. It is very surprising they were not only able to win every game in Third Selection as the main duo of Team A, but also have won every game so far in the Neo Egoist League on PXG. When they are not fighting during the game they are starting physical altercations with Ryusei being the instigator. Ego also stated that they were unable to spark a chemical reaction with each other even once during their matches and thus could never be on the same team together. Their tense opposition made Ego decide to replace Ryusei on the Blue Lock 11 lineup and was a backup wild card of "Joker" just in case Rin Itoshi could no longer play. Out of nowhere, Ryusei was chosen to assist and play with Sae Itoshi in his mission to test out the players and system of the Blue Lock Project, which scorned him even further. Yet, they managed to put aside their hatred towards each other and managed to work well in the Neo Egoist League. Given they were incapable of working well together, both players were given their own respective formation by their Master Striker Julian Loki, as a result both players managed to shine in their respective moments. However, in the final match against Bastard München, they both agreed on Julian's unpredictable plan on having the two of them in the same formation, showing how much growth they've achieved since their first clash.
