Bachira has a rather eccentric demeanor and personality. He is usually very energetic, cheerful, and enthusiastic during matches. Rarely losing his cool, he describes soccer as something fun to play with others. Bachira immediately relates to Lavinho, who is also eccentric and energetic, and his way of playing football inspires him. He has a tendency to sleep in unexpected moments, such as when he was sleeping during the tag test. He mostly oversleeps and ends up relying on Isagi or Kuon to wake him up, and then falls asleep during their team meetings; he's also been known to fall asleep during meals. He also tends to show up completely naked after every training and soccer matches. When the Neo-Egoist League starts, Bachira takes his football training more seriously in an effort to become the world-class egoist he imagines himself to be and edge closer to becoming the best in the world. Bachira now actively weight trains and mediates. During his childhood, he was bullied because of his eccentric personality and exceptional skill in football, which made him terrified of being alone. This trauma causes Bachira to create an imaginary friend who is a "monster", more specifically a football monster, because it motivates Bachira and his plays in the game. Only after he comes to Blue Lock does Bachira start facing his trauma for he finds people he is similar to and can call friends, like Yoichi Isagi. Bachira can be seen casually befriending all sorts of people despite his somewhat strange demeanor, including Isagi, Rin, Chigiri, and Kunigami. After the rematch between Isagi's Team White and Rin's Team Red, Bachira has moved past his previous trauma and has decided to be more confident and dominant on the field. He wants to become the world's best striker who scores only for himself, and thus will only pass someone the ball if they have the potential to excite him and help him play the kind of football he wants to play. Bachira has also steeled his resolve for moving forward in Blue Lock; no matter the challenge, Bachira looks optimistically at the situation, resolving to get stronger and reach the peak of each trial ahead of him. Bachira is very sweet, though can be lewd, vulgar, and filthy when worked up and if it doesn't make people around him uncomfortable. Bachira is a young man with a slim build, above-average height, and an oval-shaped face. He has bright yellow eyes and mod-cut hair that reaches up to his chin and is black with golden under-lights (when Bachira was younger, his hair was only ear-length). When he was in a junior football league, he wore jersey #8. During the Chiba Prefecture Tournament, Bachira wore the #8 jersey for Namikaze High, which had a special bird design in the center. He is 5ft 9in, and he is seventeen. He is intelligent and cunning but hides it under his bubbly, eccentric demeanor.
