Naruto: I Became a Sword Saint in Konoha

Reincarnated into the Naruto world as the last heir of the forgotten Gekkō Clan, Hoshiyomi only wanted a quiet life. One year later, he stands above Madara Uchiha, blade in hand. "Back then, Might Guy nearly ended everything with one kick. So me, cutting through Limbo with a sword? No big deal." With the Swordheart System, he’ll master every blade, rewrite destiny, and forge a new legend in the ninja world. — Description from novelcodex.org
