Avatar: The Sword Saint

After the Avatar—the one being who maintained balance among the four nations—vanishes without a trace, the Fire Nation seizes the opportunity to unleash a war that rages across the world for nearly a century. As a mere mortal incapable of bending any element, Raine has no choice but to hone his swordsmanship to its absolute limit, while spending his nights poring over ancient texts in search of the true origins of bending arts. This quiet, disciplined existence is shattered when a certain princess—one who has never learned the meaning of restraint—crashes into his life with devastating force.
