jutsu of the week
Outer Path: Samsara of Heavenly Life Technique
By summoning the King of Hell, Nagato can re-infuse new life force energy to dead bodies of those recently killed. With their rejuvenated bodies acting as an anchor, the individual souls are able to leave the crossroad between life and the afterlife, returning back to their physical form. The jutsu targets all the individuals killed, even those not necessarily killed by the Six Paths of Pain. There also seems to be a time limit to when this technique can be used, as Nagato is unable to bring back those who have remained dead for a long period of time, such as Yahiko and Jiraiya. This technique requires a massive amount of chakra, due to which it resulted in Nagato's death due to chakra overuse. Also, Nagato became severely weakened, and his hair became increasingly thinner and grayer during his use of the technique
