13 years ago there were two demons by the names of Zeno the 10 tailed dragon and Kagemaru the 11-tailed wolf that invaded the village of Yaibagakure. The shinobi held off the demons for as long as possible there forces were faltering when the best ninja in Yaibagakure the YaibaTatsujin (1) showed their skill and began to seal both demons into a small baby boy using the legendary blade known as KageYaiba. The boys name... Kasai Yaiba.
Meanwhile in konoha the same thing was happening but a little easier on konoha. They were being attacked by the nine tailed fox only their forces were losing but yondaime stepped in and sealed the demon into a newborn baby… His own son Naruto Kazama, but since his identity must be secret the sandaime changed the boy's last name to Uzumaki…
