Naruto: I Become the Strongest with Six Powers and Haki

Gekko Xuan Ying is very pleased with his new identity: Gekko Hayate's cousin. The only problem is that it's a little too early. Kakashi has just graduated, and the Third Shinobi World War is about to break out.

Looking at the System panel, Xuan Ying grins: [Iron Body: Can block B-rank ninjutsu] [Finger Pistol: Pierces rock] [Shave: Body Flicker Technique] [Observation Haki: Predicts the trajectory of attacks] [Armament Haki: Strengthens attack and defense] [Conqueror's Haki: Intimidates thousands of troops]

From genin to Kage, from Konoha to the entire shinobi world. When the might of the Six Powers meets the majesty of Haki, when Moonwalk carries him through the air, and when Conqueror's Haki coating tears the sky apart. Iron Body withstands a Tailed Beast Bomb, Finger Pistol pierces Susanoo, and Conqueror's Haki overwhelms the entire battlefield.

“Ninjutsu? Kekkei Genkai?” Gekko Xuan Ying stands at the pinnacle of the shinobi world, black and red lightning crackling around him. “Against the Six Powers and Haki, it's all futile!”

A tale of ultimate power, a legend of reaching the pinnacle of the shinobi world: it all begins here!
