He's 192 cm tall and always wears a serious expression on his face. People often confuse his expression as a glare when he looks at them. Alongside his light hair color and large frame, his most outstanding feature is his missing eyebrows.
Even though Aone is quiet and scary-looking, he actually has a kind heart dislikes when his team members argue and is very respectful. He is shy around strangers and minds the opinion others have about him. Aone has a habit of "locking on" other team's aces as they are his natural opponents. Aone is almost always silent, and his teammates are surprised when he talks.
His "read block" allows him to swiftly predict where an opponent's setter will pass the ball to the spiker. Throughout their match against Karasuno, Aone is able to barely tip the ball of Hinata's spike.
His block has been known as a high, fast, and expansive wall.
According to Coach Ukai:
He's not just tall. His arms are long, and his shoulders are broad. Those are all powerful weapons, but that's not all. He stays calm and avoids tunnel vision. He has the will to block no matter what.
He is the undisputed backbone of the "Iron Wall."
Before the Spring Tournament, Futakuchi and Aone are shown to be good friends. Futakuchi is first seen stopping Aone from intimidating Karasuno when requested by Moniwa. Aone is also seen to be the one keeping Kamasaki and Futakuchi in control when Futakuchi provokes Kamasaki.
During the Spring Tournament, it is presumed that Aone and Futakuchi are vice-captain and captain respectively.
After their match, which resulted in Karasuno winning and advancing, Aone and Hinata were shown shaking hands. Aone has formed an unlikely friendship with Hinata. In the Spring High, Aone is seen defending Hinata by making a face after his teammates criticize the latter, and he even goes as far as to speak up about Hinata's abilities since he barely talks. They have a friendly rivalry and Aone has promised Hinata that he would face him after Date Tech beats Aobajousai, though the former school loses, and they would have to wait until the Interhigh of next year to face off again. When Hinata was cornered in the public restroom by Ushijima, Oikawa, and Iwaizumi, Aone demonstrates their unlikely friendship by bowing politely to him, although the other boys disregard Hinata completely.
