The Demon Fox Crystal Sphere Technique is used by Ryun Uchiha when he is under the influence of the Ten Tailed Fox. This is the Crystal Sphere's most powerful form. To use it you have to have complete mastery over Shape Manipulation, Elemental Composition, and the Ten Tails Chakra. It is a very difficult to learn jutsu, as only one has mastered it. It, like Rasengan, does not use hand signs. The user spins Demon fox chakra into a shell, then fills the shell with pure chakra and spiritual energy and spins them in the opposite direction.
The technique virtually shreds the opponent to pieces, and can destroy a persons soul.
