Yu Bachira[]
Bachira's mother is very supportive of her son, encouraging his to desire to pursue soccer. She offers reassurance to keep believing in himself, no matter what other people think about him. In discussing the voice of a "monster" inside him, she shares that she too has a monster inside her that prompts her to pursue art.
Yoichi Isagi[]
Isagi and Bachira met during the initial game of tag that determined Team Z. Isagi was at first unsettled by him and his eccentric demeanor but they quickly bonded after their first match against Team X. They train together pretty often and Bachira has stated that he believes in Yoichi multiple times which is why he always passes to him. Bachira implies that he constantly sees a "monster" inside and around Isagi, like himself. Before the match against Team V, he reaches out to Yoichi to tell him that he'd be lonely without him if they lost the match and never got to see each other again, to which Yoichi agrees. Isagi might be the first real friend Bachira has had in years since he began being bullied but even without him around he is still able to connect with other strong players like Itoshi Rin.
Rin Itoshi[]
Rin and Bachira intially meet during the first match of the Second Selection in which Bachira, Isagi, and Nagi on Team White face off against Rin, Aryu and Tokimitsu on Team Red. After losing to Team Red, Rin voices indiference about which player to pick to join their team, and does not protest when Aryu asks for Bachira to join them.
While waiting another team to play against, Rin and Bachira train together, much to Rin's annoyance. Ultimately, Rin gives Bachira some candid advice that stays with Bachira going into their next match. Rin helped Bachira push his football skills in an attempt to win, and Bachira was more than willing to step up to the high plate that Rin and Isagi had set for him. After he broke through his trauma and became someone who is fighting for the world's best striker, Bachira becomes someone Rin trusts on the field and is closer than most people to a friendship with him.
