Kengo is in the same class as Akira, and usually hangs out with him on the roof of the school. Despite Akira's distant approach, the two share a deep friendship from childhood. He has a very cheerful disposition. His latent abilities were activated in his desire to help his older sister, who just happens to have not the best luck. He usually fights using his own body though he is no rival to Akira. he is also often mistaken as the dog or the servant of Akira because of his tendencies to follow him everywhere and behave like a pet.

His Al Cesta gloves, given to him by Akira/Shirogane, takes the form of gauntlets in battle that seemingly increases Kengo's strength.
