One's Own Life Reincarnation

This reincarnation technique was developed in Sunagakure by the Puppet Brigade. The user giving their life force to the target uses all their chakra as an intermediary. This technique can be used on both the living and dead, but when used on the dead, the user will find certain death in exchange for the soul of the deceased. While in use, the released chakra shines a pale-blue color, and if the user's own chakra is insufficient, a third party can assist. Out of humane motives, Sunagakure labeled this technique as a "kinjutsu" immediately after its development. Nowadays, the only one who can use this technique is its developer, Chiyo. As she is the sole known user, upon her death, the technique is believed to be lost.

The purpose of the technique was to give life to puppets, the puppets Chiyo had in mind being those of Sasori's parents.
