One's Own Life Reincarnation

Chiyo created this technique while a member of Sunagakure's Puppet Brigade. The purpose of the technique was to give life to puppets, the puppets she had in mind being those of Sasori's parents. When the technique was found to require the sacrifice of the user's life, the project was halted and it was labeled a kinjutsu. To use this technique, Chiyo transferred her life-force to the intended target. She first tried to use it on Sakura Haruno, but since Sakura wasn't dead it didn't cost Chiyo her life. She later used it on Gaara (with Naruto's help) to atone for sealing the One-Tailed Shukaku in his body, the reason for his death.
