Rein, an enchanter who strengthens equipment with his magic, is suddenly expelled from his guild, simply because every piece of gear in the guild has already been enhanced enough. Outraged by the absurd treatment, Rein decides to take back the enormous amount of mana he had poured into their equipment. When he casually channels it into a random copper sword, it transforms into a cheat-level weapon with 10,000 enhancement points! With zero combat experience but armed with magic that can turn anything into overpowered gear, this enchanter sets off to enjoy a new, carefree life as an adventurer! (Source: Shochiku)
