Prologue
Death stalked the village of Konohagakure.
A creature, emanating pure hatred, rampaged through the village. A demon of immense power and unknown age.
It had 9 Tails sprouting out of its back, which brought destruction to everything they touched. It took on the appearance of a monstrous wolf. Its canines looked like shark teeth, and its violet eyes pierced the souls of even the most battle-hardened Shinobi. His fur, which was deep black, writhed like the shadow of a dying candle. Tentacle like appendages shot out of the fur, piercing through flesh and stone alike. Wherever it went, destruction followed.
The Shinobi of Konoha, recognizable by their headbands sporting the Konoha symbol, bravely stood their ground against the demon. They threw everything they had at the creature. Fireballs were hurled at its body, earth-spikes pierced its feet, Kunai flew from every direction at it and Shinobi jumped in its direction with swords in hand. No matter what they did, the monster just continued to bring hell. Then, suddenly, it was gone and a bright yellow light shone in its place.
A huge orange toad suddenly dropped down on the demon, who was teleported into the forest surrounding Konohagakure. The toad stabbed a large sword in the monsters back and held it in place. Then, suddenly, the creature began to shrink, as if someone was sucking it into themselves.
The 4th Hokage, Minato Namikaze stood in the devastated forest, looking at one of his children. He had just sacrificed his son for his village. The realization struck him as soon as he looked at the infant. Before the sealing, the boy had yellow hair and bright blue eyes, but now, his eyes had turned the same dark violet colour as the demon had. His hair became a deep black, as dark as a black hole, eating away all the light around it. Even his teeth resembled that of the monster.
Minato knew what he had to do.
This demon needed to be imprisoned.
