During matches, he wears a beige mawashi featuring a single green stripe near the front left side and switches from glasses to soft contact lenses.
His family operates a flower shop, where Mitsuhashi Kei once bought carnations for Mother's Day. Personally, Mamiya enjoys following idols. In sumo, he displays formidable strength, overpowering opponents with forceful pushes—evidenced by his victory over Yuma Gojo in a practice match and his quick ring-out of Kei Mitsuhashi. However, unexpected techniques like Kei's Leaping Charge can unsettle him.
