Atsushi Kamiya is a central character in Aoki Densetsu Shoot!, known for his journey from a talented but flawed player to a respected leader and captain. He initially serves as the vice-captain of the Kakegawa High School soccer team before ascending to the role of captain following a tragic event. Atsushi wears jersey number 7 and plays as a midfielder, a position that allows him to orchestrate the team's offense and defense. His background includes a difficult period in middle school, where his selfish style of play caused friction with his teammates, leading to his rejection by the team. This all changed when Yoshiharu Kubo joined him, and together they formed a powerful and cohesive partnership on the field.

In terms of personality, Atsushi often comes across as rude and conceited, especially to those who do not know him well. He is particularly defensive and can be short-tempered when someone speaks ill of his friend and teammate, Kubo. Despite this rough exterior, he is fundamentally a kind-hearted and good-natured person who deeply cares for his team and friends. As he matures, particularly after taking on the captaincy, his leadership qualities shine through. He develops a strong sense of responsibility, manages the team with great care, and is a fast-thinking strategist who can create swift tactics to motivate his teammates and lead them to victory.

Atsushi's motivations are deeply tied to the legacy of his friend, Yoshiharu Kubo. After Kubo's untimely death, Atsushi is driven to honor his memory by leading the Kakegawa team effectively. One of his significant acts as the new captain is assigning the number 10 jersey to Toshihiko Tanaka, a decision that was in line with Kubo's will and belief in Toshi's potential. His role in the story is pivotal as the anchor of the team during a period of crisis and change. When a player named Mahori arrives and causes a rift in the club by suggesting a change in playing style, Atsushi demonstrates his wisdom and leadership. Instead of choosing a side, he arranges a practice match between the two factions, acting as a referee. This clever move allows the team to find its own way back to its core values and fighting spirit, ultimately uniting them. His passion for the game is so strong that he cannot resist entering the match himself, surprising everyone and proving that he is always thinking several steps ahead.

Throughout the series, Atsushi's development is marked by his transition from a selfish individual player into a selfless and brilliant playmaker. His abilities on the field are exceptional. He is renowned for making an excellent playmaker, using his sharp and precise passes to easily confuse opposing defenses. As his skills progress, he becomes recognized as one of the best playmakers in the nation, with his leadership and gameplay being considered on par with the legendary Kubo. His technical skill is complemented by his enthusiastic and fearless style of play, which earned him the reputation of being a fighter on the pitch. Following his graduation from high school, his talent takes him to Europe, where he plays as an ace for a famous Italian soccer team and is eventually selected for the Japanese national team. He later returns to his roots as a supporting character in the sequel series, Shoot! Goal to the Future, taking on the role of coach for the new Kakegawa Soccer team, where he is known worldwide as the courageous captain.
