Toshi's friend has been one of his closest companions since childhood. Although he initially stopped playing soccer to focus on studying due to his father's wishes, after discussing it with Kazumi and Toshi, he decided to try convincing his father that he could play both sports simultaneously. Eventually, his mother agreed, citing her own experience as a young soccer player. In the anime, this character is renowned for his "Heel/Double Heel Shoot," which creates an optical illusion of the ball disappearing. Later in the series, when opponents discovered the secrets behind Double Heel Shoot and found ways to counter it, Kazuhiro used all his strength to execute a miraculous "Triple Heel Shoot" and outsmarted them once more, cementing his status as an unbeatable soccer player with his mastery of Heel Shoots.
