Kanamori is a tall young man with a muscular body. He has a shaved head with a small amount with facial hair around his face. Along with three small scars on his forehead and one across his lip. His mawashi belt is light beige in color with a single green stripe on the left.
As he has experience in dealing with delinquents himself, he has an ultra-serious personality, and hates Mizuki's aloof attitude.
He is the captain of the well known Ishigami High School, and known all over Japan as the "Hercules", as he was able to raise and throw Sada Mizuki out of a Dohyo with a single arm. His sumo technique is the Migiyotsu and Backward Belt Throw, which he used to defeat Gojo Yuma, when Yuma's trouble with close-area combat is exposed. According to Sada, if he catches his opponent with his left over-arm grip, he will definitely win.
