Naruto: The Uchiha Who Wields Haki

An Uchiha in Konoha… with a pirate emperor’s power in his veins. In a village that fears the Uchiha, Uchiha Ren gains a mysterious System—and with it, the Whitebeard Template. No hand seals. No mercy. Just overwhelming power: Armament Haki, Conqueror’s Haki, and a will that crushes opponents before he even strikes. The elders want him controlled. The clan wants him claimed. But Ren only wants one thing—to rise to the top on his own terms. — Description from novelcodex.org
