Nozuchi

Nozuchi (埜坤, Nozuchi), more commonly known as the Zero-tails (零尾, Reibi) is one of the nine tailed beasts. Currently, She is sealed in Usagi Shiharu

Background
Nozuchi first came into being in the waning days of Hagoromo Ōtsutsuki's life. Using the Creation of All Things, Hagoromo separated the chakra from the Ten-Tails and divided it into nine separate constructs: the tailed beasts.[2] [3] Some time after being created, Hagoromo sat down with all the young tailed beasts and told them that they would always be together, even when separated, and that one day they would become one entity again with different names and forms. Then, when the time came, they would know what true power was.[4].

Years later, Nozuchi was captured, and eventually fell into the possession of Ryūgakure.
