Background
Great destruction was left in the wake of the fourth war. In order to reinstate their power, Sunagakure thought up and idea of creating a ninja with the chakra of tailed beast. Looking about the battle field, they were able to collect residual tailed beast chakra mostly from Isobu and Son Goku. They then decided to see if a person could host the chakra of two tailed beast. After months of failure often resulting in the deaths of the host, after a year of trying a child was born with unique chakra. This child was Zaitenmaō. Testing out his chakra, they found that his unique chakra perfectly merged with the tailed beast chakra. They then sealed the remaining chakra into him. Effectually creating something not quite human and not quite a tailed beast, but something in between. They then raised this child to be a great warrior, eventually becoming Sunagakure's pride and joy. Zaitenmaō devoted his life to the protection of Sunagakure and its people.
