Once upon a time, there lived a fox sprit with nine tails and he was so powerful that whenever he shook those tails landslides and tsunamis would result.
The suffering people gathered the great shinobi clans to fight this menace. Finally, risking his life, one ninja attempted to imprison its soul but was attacked by a mask wearing shinobi.
Having no other option, the brave shinobi imprisoned not only the demon but the mask wearing shinobi and died.
The brave shinobi was the forth hokage, the fire shadow, champion of the village hidden in the leaves.
The mask wearing shinobi was the strongest of the uchiha clan, madara uchiha, master of manipulation.
The fox spirit was the nine tailed demon fox, Kyūbi no Yōko, scourge of the land.
The one to contain them all and use their powers at will, naruto uzumaki, the one who will destroy the village hidden in the leaves if it's the last thing he'll do.
