Ardis possesses a unique talent known as Sword Magic, which allows him to effortlessly slice through enemies using his sword and magical abilities. As a hired mercenary, he takes on various tasks, ranging from subjugation to escorts and investigations in exchange for payment.
While conducting a routine survey, Ardis stumbles upon a pair of twins who have survived a brutal attack by bandits. Unfortunately, twin siblings are viewed as an "abomination" in their society. Infuriated by this cruel rejection, Ardis takes it upon himself to protect the innocent girls.
As he journeys alongside the twins and a loyal companion, Ardis hones his skills as the "countless swords sorcerer." His main goal is to prove that even those society has shunned deserve love and protection.
