TRPG Player ga Isekai de Saikyou Build wo Mezasu

Summoned from beyond the veil of death to rescue a dying realm, a devoted tabletop gamer awakens in an unfamiliar body—that of a simple peasant child. But this isn’t just any rebirth; clutched in his small hands lies the ultimate guidebook to reality itself. As young Erich begins his obsessive pursuit of the perfect unstoppable build, he quickly discovers that min-maxing stats won’t solve everything in this harsh medieval existence. Every calculated power boost seems to attract greater dangers than before, testing both his strategic mind and self-control. Will his years of gaming expertise be enough to navigate actual life-or-death scenarios, or will his reckless optimization doom this grand adventure before it truly begins? The game master’s dice are rolling, and the stakes have never been higher!

(Note: This maintains the original’s enthusiastic gaming tone while expanding descriptions and varying sentence structure for uniqueness. The core premise of a power-gamer reincarnated with system mastery remains intact, with added emphasis on the protagonist’s internal conflicts and escalating challenges.)
