Name: Soul Sphere jutsu
Description: The Soul Sphere Technique is an ancient jutsu that was thought only able to be used by the "Sage of the Six Paths". Naruto Uzumaki found out about this jutsu from Tsunade, who had been researching it. Naruto used this jutsu against Pain and almost killed himself in the process. The Soul Sphere Technique requires the utmost chakra control due to the user having to draw fragments of his chakra and soul out of their body. Once extracted the user condenses the chakra and soul fragments into a sphere. Depending on how much chakra and soul fragments are concentrated will determine the destructive power of the jutsu. The jutsu rests on the closed fist of the user so that it may be used in a more accurate hit. This jutsu qualifies as Kinjutsu due to how the sphere is formed and should only be used as a last resort.
- Unknown to most ninja historians, this jutsu was the last that the "Sage of the Six Paths" (Rokudou Sennin) produced before he took his last breath.
When Ryun trained with Rokudou Sennin in the Hall of Heaven, Rokudou created a copy of himself and fused it with Ryun, thus Ryun learned the Soul Sphere.
This technique was found by the kages of Kagegakure and demon village.
