Otoya Eita.

Eita Otoya (乙オと夜や影エイﾀﾀ, Otoya Eita) is a contender of Blue Lock.
When first introduced, he was ranked #4 during the Third Selection and he later played as a right wing and right-back for the match between Blue Lock Eleven and the Japan U-20 team.

Otoya is a handsome young man who has short, flat white hair with a strand of hair in the middle that is dark green, along with the underside of his hair being that same dark green color. His face is slim with a chiseled chin and thin, low-lidded eyes that are dark in color. Otoya has spindly limbs that allow him to be agile on the field.
At Blue Lock, Otoya wears the standard issued body suit (black with gray stripes) and tracksuit. During Second Selection, he wore Team Red's #33 jersey and wore Team B's #33 white jersey during the Third Selection. Only once the Japan U-20 match begins does he don an official blue Blue Lock player uniform with jersey #9.

Otoya has a laidback and relaxed personality, rarely being shown as pressured or under stress even during a match. He has no problem taunting his opponents and appeared to be entertained when Rin and Shido began to fight after their match.
He also is very confident in his abilities, telling his team to play defense during his Third Selection match and not to talk back. Despite this, he does acknowledge when he is impressed by a teammate or an opponent, as seen when he was hyped up by Chigiri's speed.
Otoya has lived his life by "going with the flow," and his fundamental approach was not to worry. When anything unpleasant happened to him, he would override it with fun things and forget it. This personality trait is what made him so compatible with Tabito Karasu as a partner.

forwards: also known as strikers, have the main objective of scoring goals. They are often the players who get the most attention since their role is designed to be in a scoring position. They also take part in penalty kicks and corner kicks when the opposing team kicks the ball out of bounds. They are normally the players in charge of starting off the game at the start and halftime.
Shadow Striker: Shadow strikers operate as one of the team's main goal scoring threats. Usually coupled with another forward, they aggressively push up into goal-scoring positions as the ball moves into the final third and look to press opposing defenders when out of possession.
Otoya is a very capable and versatile player whose main strategy for scoring goals is to slip past defenders, charge up to the center of the goal, and await a long pass from a teammate. His "Stealth Steps," which combine his speed and off-the-ball movements, is what got him selected by Ego to be a starter for the Blue Lock Eleven. After training in the NEL, Otoya has greatly improved his ability to stay out of the limelight to be a greater assist to Meguru Bachira

high speed: Otoya is incredibly quick on his feet, reacting quickly to opposing players and using his speed to intercept them. Unlike Chigiri and Zantetsu's speed, which is a straight-line type based on leg strength that excels in wide open spaces, Otoya's speed is a curved line type for weaving through narrow spaces using agile, delicate footwork.
Off-the-Ball Movements: A term used to describe the moments where players are not in possession of the ball.
Otoya is able to use his agile footwork to position himself behind a player without them noticing or in ideal spots to receive a pass.
Stealthy Steps: Through combining his speed with his off-the-ball movements, Otoya is able to very quickly weave in-between opposing players with unpredictable footwork without them realizing before it is too late to react. It is this technique that gives him his "Ninja" epithet

the blue lock is a training facility built to attract top Japanese soccer players who will live in the facility and follow a strict training regimen designed by Jinpachi Ego himself. The center of the facility also contains a soccer arena that is used to host professional matches. There are five stages in the project, but only one player will be able to complete it. The player who makes it to the end of the project will become a bomber in the Japanese league. Players who are eliminated from the project will be barred from the Japanese league forever. New challenges are constantly appearing in the Blue Lock, which eliminate a huge number of players. The building is a massive structure that takes up the entire area of a large cliff in the mountains of Japan and reaches the height of a skyscraper. The building is shaped like a pentagon and is thus divided into five separate sections. Each section is designated as a stratum, and the stratums contain a variety of different rooms, including living quarters, a dining hall, gyms, dedicated training rooms, several soccer training pitches, a soccer arena in the center that can host professional matches, and even enough space to host multiple training sessions simultaneously.
