The chronic shoulder stiffness he accumulated over years of being a corporate slave disappears, and riding that wave of exhilaration, he just keeps swinging his weapon, training relentlessly, building up his skills, and heading into dungeons… He quickly settles into his new isekai life. But his growth curve has one peculiar trait: "it's nothing but physical-specialized skills"――!?!?
