Bunny Iglesias comes across as calm, polite, and soft-spoken, with a smile that often masks deep emotional turmoil. He speaks with a detached honesty, occasionally revealing a bitter or melancholic side, especially when discussing his own connection to football. Although respectful in conversation, his comments can be subtly condescending or self-deprecating. Despite this, he displays a quiet appreciation for the passion of others, hinting at a complex inner world shaped by unresolved feelings about his place in the sport.

Bunny is a tall young man with a cross-shaped scar on his face, another on the left side of his neck, and many others scattered across his arms and probably his entire body. He has medium-length, light purple hair, red eyes with black pupils, and despite his youthful appearance, he possesses a rather robust and athletic physique.

In his casual attire, he sports a black cap with a rabbit face on the front and matching scars, an unbuttoned coat, and a white T-shirt with the inscription "Only Me." He completes the outfit with light-wash jeans and black sneakers.

is a player for Bastard München U-20 who plays in the striker position. He is a German U-20 prodigy striker and plays for Bastard München during the Neoegoist League as the team's ace and main striker. He is also a member of the New Generation World's Best XI.

Kaiser is shown to be an arrogant young man with a superiority complex. He views everyone around him as mere small-time actors compared to his grand leading role as the star of his world. Though he is arrogant and cunningly rude to people he sees as beneath him, he is not unnecessarily rude to his teammates, but will put them in their place when they speak unnecessarily, even if it is for their own good. Despite Kaiser being arrogant and rude, he knows when to rein it in around people who are definitely better and superior to him, such as his team leader and the best striker in the world, Noel Noa.

After the match against Ubers, Kaiser was immensely frustrated when he lost to Isagi. He originally joined Bastard Munich because it was the fastest way to reach La Real, but now he can't simply leave the Neoegoist League after losing to Isagi.

Kaiser believes that the moment people believe things are impossible, they're programmed to give up. Those who sacrifice their talents in exchange for long, tedious lives are the ones he hates the most.

Kaiser used to be a mentally weak person who constantly gave up on things he thought were impossible. To remind himself never to fall into that weak-mindedness again, he got a blue rose tattoo on his neck, which he believes symbolizes achieving the impossible.

Kaiser is a tall, quite attractive young man. He has blue eyes and blond hair. His hairstyle includes a mullet with blue highlights at the ends, and two bright blue rat tails at the ends. His eyes are accentuated with red eyeliner. He has a tattoo of roses and thorns that extends from his neck, down his left arm, and down to his hand. At the end of his hand, he has a crown with a keyhole and three stars. During the Neo-Egoist League, with Bastard München, he wears the number 10 jersey.

He is a football prodigy, known as the best player in Japan. Sae is also a member of the "New Generation World's Best Eleven" and the Real Sociedad youth team. He is the older brother of Rin Itoshi.

Sae's main goal before the start of the series was to become the best striker in the world and, in turn, the best player in the world, but after leaving Japan and experiencing the professional league in Spain, he changed his dream to become the best midfielder in the world, after realizing how truly weak Japanese football is compared to the rest of the world.

At the beginning of the series, he is in Japan only to renew his passport, but after hearing about the Blue Lock project, he decides to stay to find out firsthand the results of the project, later joining the Japanese Under-20 National Team to face the Blue Lock 11 in the match that will decide the Japanese squad for the next Under-20 World Cup, for which he recruited Shidou Ryusei.

After the Japanese Under-20 National Team match concluded, he admitted to Rin that he had been wrong about strikers in Japan and that he believed Isagi Yoichi could revolutionize football in Japan.

From a young age, Sae has been cold, outspoken, and very serious. He has only cared about becoming the best striker in the world and has only had time for things that bring him closer to his goal. Sae can also be arrogant and condescending, looking down on others, even those older than him and with more authority in the organization. He is selfish in his football game, but has proven capable of restraining himself and playing his position without trying to overshadow others unnecessarily.

Sae takes great pride in his football role and belittles Japanese football and everyone involved. He claims he'd rather die or play in Europe with a group of college students than play in the J-League or for the Japanese national team. He's very confident in his abilities and wholeheartedly believes that no one in the Japan U-20 team is worthy of his skills as a teammate. He dislikes the fact that he was born in Japan, saying things as if he were simply born in the wrong country.

Sae seems to easily gain the respect of most people in a room due to his reputation and ability, even with his bad attitude and blunt way of speaking, and is able to manipulate and attract loud and harsh people to listen to him or do things his way. Although Sae is a difficult person, he is not impossible to work with, especially if he is getting something out of it. He, out of pure self-interest, decides to stay in Japan on a whim after learning about the Blue Lock Project and even joins the Japanese U-20 National Team for the match against the Blue Lock 11. But when his interest is satisfied, he has no problem abandoning those he deems unworthy of his time.

Although Sae displays arrogance, he doesn't mind remaining in his role as a key midfielder and passer.

Sae is a tall but thin young man with reddish-brown hair and thin green eyes that are framed by a set of long lower lashes much like his brother, Rin. During the National Representative match, he dons the white number 10 jersey of the Japan U-20 National Team with a black T-shirt underneath and black gloves.
