Legacy of the Six Paths: Ryun Uchiha vs Seireitou Hyūga

"The End"
It was the most obscure area of the Land of Mountains, one few often tread — a blessing in disguise, as it would turn out. Since his retreat from the national stage, Ryun Uchiha, the legendary grandson of Madara Uchiha, had lived here in seclusion, free to practice his techniques away from the prying eyes of the shinobi world. For the first time since his reclusion, Ryun removed the mask he had used to cover his face. Though he was around fifty-six, in age, he hadn't seemed to age at all — thanks to a special technique that he had developed during his hermitage. He sighed, almost in relief, letting his spiky, long, blue-tinted black hair flow freely in the wind. At that moment, the ground contorted beneath him, as Black Zetsu rose up from the earth.

"He's entered this territory." Zetsu reported cryptically.

"About damn time." Ryun snapped comically, his eyes shifting from their usual stone-black, to the Sharingan he was so infamous for.

"As you've ordered, I have swept the surroundings. There are no signs of human life anywhere within several thousand miles of this location. The surrounding mountains provide a nice cover as well. You will be free to cut loose out here." Zetsu explained.

"Excellent." Ryun replied, turning and smiling coyly at Zetsu. "Go now. If you're anywhere within a couple hundred miles of this place when we start, you'll die."

Without a word, Zetsu sunk back into the ground, vanishing from sight shortly thereafter. Ryun then crossed his arms, leaning up against a nearby tree for support as he waited. The nostalgia of this situation swept over him like the summer breeze. This had been the location of their first real battle, nearly forty years ago. Now, the world itself would see how much the two men had changed. With a twitch, Ryun detected a familiar presence entering the area. It was undoubtedly the man he respected most, and yet, at the same time, desired to defeat even more; Seireitou Hyūga had arrived.
