Naruto: God of Shinobi

When a failed prank leaves Naruto with a head injury and a mind suddenly clear for the first time in his life, he begins to see the truth that has been hidden from him for twelve years. His father was the Fourth Hokage. His mother was the last survivor of a destroyed clan. And the demon sealed inside him was not born evil, it was used. Naruto is no longer the class clown. He is cold. Calculating. And he has decided that the world owes him a debt. NARUTO: GOD OF SHINOBI follows a darker, more analytical Naruto as he uncovers the lies of his village, builds alliances outside its walls, and sets his sights on a goal far greater than becoming Hokage. He will rebuild the Uzumaki clan. He will correct a broken world. And he will become the God of Shinobi. — Description from novelcodex.org
