Makina, a blacksmith who worked in the renowned guild "Silver Wings," is expelled from his guild. The reason? Guild members who don't value their weapons believed it was more cost-effective to buy them rather than employ his services. Lost and uncertain about his future, Makina receives an invitation from his childhood friend and adventurer, Aria. She joins Aria's guild, "Rainbow Butterflies." It's here that Makina's blacksmithing talents truly shine. With his weapons in the hands of guild members, they collectively rise to become the mightiest of all. (Source: MU)
