Zantetsu has spiky, dark-colored hair and fake glasses that he wears even while playing. At Blue Lock, Zantetsu wears the standard-issued body suit (black with gray stripes) and tracksuit. During the First Selection, he wore Team V's blue #10 jersey and wore Team V's gray-capped cleats, and during the Second Selection, he wore Team White's #53 jersey. Personality: Zantetsu is not a very intelligent individual, and when speaking, he mainly uses idioms just to sound cooler, but he almost always says them incorrectly and always asks others if what he has just said is correct. Due to that, Reo and Nagi have nicknamed him "Baka Zantetsu". On the other hand, he is a calm and coolheaded individual but loses his calm when being called an idiot, as it is something that bothers him immensely, and he believes that truly intelligent. The other reason he is called an idiot is for his lack of comprehensive ability. At school, he couldn't understand what the textbook was saying, couldn't calculate the train fare, and misunderstood most of Blue Lock selection's activities. He is also a determined person, as his motto is "Carry out what you've set out to do", and since he found out that he is good at running, he decided to devote himself to sports just so that he can achieve his dream of becoming the "World's Most Esteemed Moron", though the reason he chose soccer is purely on intuition. As he comes from a family of dentists, he never forgets to brush his teeth and considers himself the black sheep of the family, as he is the only one who isn't smart. Their family motto is "Even if you forget ceremonial occasions, don't forget to brush your teeth" Additional: His glasses are actually fake, and he wears them only to look smarter. His hobby is meditating, especially sunbathing. His favorite foods are hamburgers and curry. His least favorite food is fish (he can't tell the difference in their taste). His strengths are that he's honest, a good guy, and an eager learner. His weakness is the part where he's stupid. His full name is Zantetsu Tsurugi. He's 17 years old, and 6'2.

Reo is a tall young man with a lean build. He has chin-length purple hair that is tied in the back and has two asymmetrical locks that frame his face. He has big, bright purple eyes with a black outer ring around his eyes, and small purple eyebrows. At Blue Lock, Reo wears the standard-issued body suit (black with blue stripes) and tracksuit. Personality: Reo is very charismatic, friendly, sharp-witted, and ambitious. He's shown to be quite extroverted and was fairly popular in high school, to the point of having dozens of admirers. Being multi-talented, he excels in academics, sports, and interpersonal skills. Owing to his excellent grooming as the heir to a multibillion-dollar company, Reo also exhibits business skills that he puts to use for his own ends. Due to his high emotionality, he can even get violent when he loses his temper, as seen when he elbows Jingo Raichi after some taunting. On the whole, Reo is a friendly and clever young man who knows what he wants out of life and will pursue it until he's satisfied. He gets deeply upset when things don't go his way, perhaps owing to his wealthy upbringing. Generally, he seems to feel every emotion with full force and is extremely aware of his own faults and shortcomings. Additional: His best friend is Nagi Seishiro, whom he considers his invaluable treasure and spoils constantly or whenever he can. He's 18, and 6'1. His full name is Reo Mikage and he's extremely rich, the heir to the Mikage Corporation.
