A blacksmith who once supported a famous guild is unjustly expelled and starts over as an adventurer! With his own ultra-powerful weapons, he dominates the battlefield in exhilarating style!!

“We don’t need some guy who just tinkers with weapons!” Despite tirelessly forging weapons for the rough and reckless members of his guild, Makina, the blacksmith who had supported the famous guild Silver Wings, is suddenly and unfairly expelled. Wandering the streets in despair, Makina happens upon his childhood friend Aria, who is being attacked by a group of thugs. He immediately leaps to her aid, cutting them down with his beloved sword Ifrit. After learning what happened to him, Aria invites Makina to join her up-and-coming guild, Rainbow Butterfly, as an adventurer. There, Makina’s extraordinary blacksmithing skills shine once more. Together with his comrades—each wielding the cheat-tier weapons he crafts—they set their sights on becoming the strongest guild of all!
