Rikiya Gaou  

, 峨王力哉

Gaou is a 1st-year student (Grade 10) in Japanese high school who has recently joined an American football team despite being new to the sport. Standing at two meters tall, he possesses immense strength and resembles a caveman with long black hair, red marks on his cheeks, and a large scar on his forehead. Gaou holds the Japanese bench press record with over 200 kilograms and is capable of destroying furniture, tearing metal guardrails, and breaking normal people's bones with his bare hands. He wears a titanium alloy mouthpiece due to his powerful jaw that tears apart ordinary ones. Gaou has spent his entire life searching for someone who can match his power and joined the football team because Marco promised him that the most powerful teams in the country possess such individuals. He shows little respect towards those unwilling to face him directly but holds tremendous respect for those who do, even if they are crushed. Additionally, Gaou follows the rules of American football and will not tackle a player without the ball.
