Kazuma Numai, third-year ace and jersey number 4 at Nohebi Academy, stands 1.79 meters tall with a muscular frame, ochre eyes, and blonde hair streaked with lighter tones. Weighing 72 kilograms, his August 4th birthday places him under the Leo sign—a fitting match for his fierce determination. Renowned for grit, he once played through a dislocated thumb, prioritizing team victory above personal pain. Though Nohebi’s tactics draw scrutiny, he bristles at accusations of cheating, fiercely defending the team’s skill-driven legitimacy. His leadership blends blunt honesty with loyalty. He mentors first-year Naoyasu Kuguri, consoling him after defeats while openly admitting Kuguri’s technical superiority. During the Spring High Preliminaries, an injury forced him to the sidelines, with Kuguri stepping in. Returning as a pinch server, he unleashed a thunderous jump serve despite his injured hand, electrifying his team’s morale. Vocally rallying teammates to seize a nationals berth “no matter what,” his resolve never wavers—yet post-loss, he reveals vulnerability, comforting Kuguri with shared frustration over defeat. Athletically, he excels in raw power (5/5), jumping (4/5), and stamina (4/5), though strategy (2/5) and technique (2/5) lag behind. Off-court, he favors fried rice with mustard greens, and his serpent-themed surname—derived from “numamamushi”—ties him to Nohebi’s snake motif. Interactions showcase layered dynamics: critiquing younger players’ perceived complacency yet nurturing their potential, while trading playful jabs with fellow third-years, balancing rivalry with camaraderie. Every action underscores a creed—victory demands relentless effort, but never at the cost of team bonds.
