Senken no Majutsushi to Yobareta Kenshi

A swordsman wields a unique form of magic that allows swords to be controlled and flown through the air to strike enemies. This technique has never existed in the history of magic. Ardis, a mercenary, takes on various jobs such as subjugations, escorts, and investigations for payment. After completing a survey mission, he rescues two twin girls whose caravan was attacked by bandits. In their world, twins are regarded as abominations. With the twins and a girl who follows him, he suppresses his anger toward a society that treats the girls harshly, partly due to the goddess’s influence.
