Naruzou Machio

Machio serves as a part-time physical education teacher at the academy the protagonist attends, while also working as a professional coach at Silverman Gym. At first glance, he appears to be a handsome and approachable young man, but the moment he flexes his muscles, his clothing is instantly shredded to reveal an astonishingly massive physique. Passionate about promoting fitness culture, he frequently delivers in-depth explanations on exercise equipment and sports physiology, effectively acting as the show's resident fitness guru.
