Description
Masato Hyodo possesses a large, muscular build at 186 cm and 128 kg, with striking teal eyes and teal hair. A prominent crescent-shaped scar arches above his nose. He attended Eigadai Affiliated High School, initially participating in the sumo club before embarking on a professional career with Minagawa Stable under the ring name "Daihannya Nagamitsu," reaching the rank of East Maegashira 4.

He is the older half-brother of Chihiro Kunisaki, sharing the same mother but different fathers. During their childhood, Masato habitually took up activities after Chihiro started them, surpassed his brother's skill, and then abandoned them, driven by an inability to accept second place to Chihiro despite privately acknowledging his talent. After his parents' divorce, Masato lived with his father. His rivalry manifested in taking or damaging possessions important to Chihiro.

Athletically gifted, Masato excelled in soccer, basketball, judo, and boxing, potentially exceeding Chihiro in raw athleticism. He began sumo training just two years prior to his introduction, rapidly achieving a skill level comparable to nationally recognized talents. However, his arrogance and disregard for sumo's rules frequently led to unconventional losses through avoidable errors, preventing him from earning an amateur moniker. His approach was flashy, loud, and often oblivious, leading others to label him an "idiot."

At Eigadai High, Masato moved between clubs causing disruptions until a confrontation at the sumo club resulted in his defeat and subsequent commitment to the sport, focusing on becoming a regular competitor. Post-high school, he declined an invitation to Nagato Stable, choosing Minagawa Stable instead. His documented professional matches include a defeat against Hinomaru Ushio. His blood type is B. The origin of his facial scar remains unspecified.
