Description
Tsuyoshi Kanamori, a third-year student at Ishigami High School, serves as captain of its sumo club. He possesses a formidable physique, standing 189 cm tall and weighing 138 kg, with grey hair, black eyes, three small scars on his forehead, and one across his lip. His typical attire includes a light beige mawashi featuring a green stripe and a black shoulder brace. Known by the epithet "Hercules," he earned this title after lifting and throwing fellow sumo wrestler Mizuki Sada out of the dohyo with a single arm.

Kanamori maintains an ultra-serious personality, shaped partly by past experiences with delinquents. This disposition fuels his clashes with Mizuki Sada's more aloof attitude. As captain, he prioritizes strict discipline and rigorous training, reflecting his leadership focus on structure and accountability.

His sumo techniques prominently feature the Migiyotsu (left over-arm grip) and the Backward Belt Throw. Sada notes that if Kanamori secures his signature left over-arm grip, victory is virtually assured. He employs destabilizing strikes like the "Cannon Slap" early in matches and often initiates bouts with aggressive forward rushes to overwhelm opponents quickly.

During his second year, Kanamori led Ishigami High to win the District Preliminary Tournament championship. In his third year, he faced Hinomaru Ushio of Odachi High in a practice match. Initially dismissive of Ushio's shorter stature, Kanamori accepted the challenge after Ushio vowed to quit sumo if defeated. Despite his confidence, Kanamori lost when Ushio countered his Backward Belt Throw. This outcome influenced Kanamori's subsequent decision to limit exposure of his team's techniques before tournaments.

At the National High School Sumo Championships' Chiba Prefectural Preliminary Bouts, Kanamori defeated Yuma Gojo using the Backward Belt Throw after enduring Gojo's karate-inspired strikes. He later lost to Tenma Hikage in the individual competition, pushed out of the ring relatively easily, resulting in a second-place finish for the individual bouts.

Parental disapproval of pursuing professional sumo, citing his lack of standout achievements at the Inter High tournament, led Kanamori to forgo a professional career. After high school, he transitioned into coaching, aiming to pass on his sumo knowledge to the next generation.
