In Japanese mythology, the Nozuchi or Nodzuchi is a spirit of the earth that is found in open plains hiding in the shadows of the plants and trees. While it is not an evil or mischievous spirit, it is wild and uncontrollable, thus it will sometimes bring harm to humans it sees as intruders or threats. Its name means "god of the plains." It is also another name for the serpent monster Tsuchinoko, which is now seen more as a cryptid that takes the form of a fat snake.
As Kayanohime or Kaya-no-hime it is a goddess of the fields and grass born from Izanami. Together with Ohoyamatsumi they would bear eight children.
"A Japanese earth spirit. It hides in the grass or in the shade. It's not evil, but it's a bit violent and may harm a human if it sees one."

Nozuchi can be found in the Great Underpass of Ginza, past the Manikin hideout and immediately in the vicinity of the Matador encounter. It's ability to drain Force skills makes it a good choice for battling Matador, and it becomes more useful should it be leveled up to learn Counter and Rakukaja prior to the fight. Nozuchi can evolve into Gui Xian through leveling up.
