The Swordsman Called the Countless Swords Sorcerer

Sword Magic, where a sword is manipulated using magic to freely fly in the air, cutting down enemies.

Ardis is a user of this new magic art that has never been seen before

throughout the entirety of the history of magic.

As a mercenary, he undertakes various requests in return for remuneration, including subjugations, escorts and investigations.
On the way home from a survey request,

he protects a pair of twin girls who survived their caravan being attacked by bandits,

however in this world twins are considered “abominations”.
Along with the twins and a girl who accompanies him as a follower,

he holds back his anger at the world which looks coldly

at the twin girls due to the goddess’ intervention.
This is the story of such a swordsman called the countless swords sorcerer.
