He is the youngest and only second year student in the Rikkaidai line-up, thus earning him the title "Second Year Ace." He joined Rikkai because he heard the school had a very strong tennis team, but his hopes were quickly crushed by the Three Demons. He usually acts childish and friendly, though he is actually very violent on the court, often causing serious injuries that require hospitalization. He reforms in the anime after being beaten by Fuji, though he retains his nature in the manga; in the nationals in the anime, he returns to his violent playing style. While under high pressure or after sustaining injury, The whites of his eyes turn red, becoming bloodshot, and his power, skill, and speed increase. He becomes much more violent while in this state. Later, he develops a "Devil Mode", which turns his skin red and his hair white. His bloodlust and destructive power are greatly enhanced, and he solely focuses on crushing the opposing players using purely violent means. Kirihara's trademark shot is the "Knuckle Serve", a more powerful and extreme version of the Twist Serve, in which the serve goes straight for the opposing players body.
In the manga he is one of the few players that can use the "Muga no Kyouchi"(State of Self-Actualization),as shown on chapter 216:Kirihara Akaya vs Fuji Syuusuke in the manga,where he uses different techniques from other players to put up a fight against Fuji.In the manga it is also said that Kirihara has surpassed his limit for him to reach the State of Self-Actualization.However these does not happen in the Anime.
