In this magical realm, there's an art known as Sword Magic where a sword can be manipulated through magic to fly freely in mid-air and slay foes. A person named Ardis has mastered this new form of magic that has never been seen before throughout history. As a mercenary, he takes on various assignments for payment, such as subjugations, escorts, and investigations.
During one assignment, while returning from a survey request, Ardis encounters twin girls whose caravan was attacked by bandits. In this world, twins are considered "abominations" due to divine intervention. Along with the twins and his companion, he restrains his anger at society's cold rejection of the twin girls. This tale follows the journey of such a swordsman called the Countless Swords Sorcerer.
