One's Own Life Reincarnation

This reincarnation technique was developed in Sunagakure by the Puppet Brigade. The user by 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 pale-blue color, and if the user's own chakra is insufficient, a third party can assist. Out of humane motives, Sunagakure labelled this technique as a "kinjutsu" immediately after its development. Nowadays, the only one who can use this technique is its developer, Chiyo

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