Many years ago, the Sage of Six Paths had someone special to him. In his early years he met a girl named Karyuu Kaida. Kaida is the First Dragon Princess that's often seen in every child's storybook. It was peaceful until the Sage discovered that there was a big amount of chakra lurking somewhere. They decided to find it and conceal it for it will not be used by the wrong hands. And then they found it. The Ten Tails, a massive creature full of hate. When the Sage and Kaida found it, they decided to seperate its chakra because there was no other way to get rid of it. They split it into nine. The One tail, Shukaku Two tails, Matatabi Three tails, Isobu Four tails, Son Goku Five Tails, Kokuo Six Tails, Saiken Seven Tails, Chomei Eight Tails, Gyuki Nine tails, Kurama. They treated the beasts as their own children but even though the Sage was the one who made them, the beasts seems more attached to the woman. The world was peaceful again. They thought that was the end. But it was only the beginning of a story that exceeds decades to finish.
