The Enchantment Mage, Rain, who could enhance weapons and armor with 'enhancement points', was suddenly fired from the adventurer's guild. His former companions, who had only seen him as a useful tool, no longer needed him after he enhanced all their equipment, making the guild the strongest on the continent. After reclaiming the enhancement points he had given to the guild's equipment, Rain uses them to create the strongest weapons and armor for himself, starting with a copper sword enhanced 10,000 times. Thus begins the carefree life of the expelled cheat Enchantment Mage as he becomes the strongest user of weapons and armor.
