Naruto: I Am The Summoning of The Yuki Clan
Millions of thousands years ago, Hyouka was a human on Earth. Now, he was a nine-tailed fox capable of mass-destruction, in the Narutoverse.
Memories of his past life had long faded already, with only important ones remaining in the depths of his mind.
His past life was full of deceit, manipulation, and dirty tactics. His new life wasn't much better. Once hailing from the prideful Hyouma fox clan as the young heir, all were killed except him.
Hyouka lived alone for centuries, not having the littlest bit of companionship, as time slipped away like sand between your fingers, years passed like seconds for him.
He was lonely for so long, until a certain human summoned him, using the long forgotten summoning scroll that the Hyouma once used.
This person was Yuki Fuyumi, the ancestor and founder of the Yuki clan.
But time passes quick, and the scroll was forgotten soon after, that is, until the time of the Bloody Mist Policy.
