Kiyosei

Kiyosei (聖, Kiyosei), also known as the Gray Fox (鼠狐, Shoko) is a created by Shingi, as an attempt to create a mirror image of Kurama. The beasts' construction, is based from the chakra of Kurama, as well as portions of the God-Tree. As a image of Kirama, Kiyosei has chakra, and prowess comparable to it, and with the influence of the God-Tree, sub sequentially surpass it. This beast itself, is seemingly feared even by the original tailed beast granted only it's prowess. Now it resides either with Shingi, or walking the faces of the world.

Background
Kiyosei, was first brought into the dreadful shinobi world, a little time after the group known as the Black Crown attacked the Kage summit. It's creator, Shingi was able to determine what would be needed to protect his village against the power of group. These plans wouldn't unfold until the appearing of Kurama, where a old friend of his fought against the fox, taking its chakra, and restoring his own beast. Remembering a great debt he owed, he returned to Shingi, giving him sixty percent of Kurama's chakra. And using the Creation of All Things, to help form the image of the beast. The full creation of the beast was put to a halt, as Shirou was forced to attend to other conflicts, leaving Shingi with the project alone. Because he lacked the power Shirou had, Shingi sat astray with the chakra of image of the beast for the longest. It wasn't until later, after Shingi got a new product, where he was able to finish the creation on his own, later naming the beast "Kiyosei" due to the Holy Tree's help of finishing.

Trivia
Kiyosei means Holy Spirit, for the sake of kanji (聖) repeation, I only used it once.
