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. Using it on the living can save and restore the target from an otherwise fatal condition but will leave the user greatly exhausted. 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 colour, and if the user's own chakra is insufficient, a third party can assist, but only the actual user of the jutsu will die.
- Out of humane motives, Sunagakure labelled this technique as a "kinjutsu" immediately after its development. As such, the only one who can use this technique is its developer, Chiyo, and as she is the sole known user, upon her death the technique is believed to be lost forever.
- The purpose of the technique was to give life to puppets, the puppets Chiyo had in mind being those of Sasori's parents. It was also for a means to give combat puppets life to increase their efficiency in battle.
- In the anime, Ranmaru was capable of restoring an almost dead Raiga similar to how Chiyo restored a fatally injured Sakura Haruno.
