Like the "Chakra Force Sealing Technique" this is the technique of the Nubatama Clan that was created FOR the sealing, this allows the members of the clan to release the sealing jutsu on a member after/on the verge of death.

This technique was also created by the 2nd leader of the Nubatama Clan, Kisaki Nubatama,. However, unlock the first technique, this ones sole purpose is to allow members of the clan to absorb the stored chakra from the previous seal and transfer it to the reserves of the user. Giving the absorber the extra chakra reserves and can call upon the chakra similar to the way a jinchuriki called upon the chakra of it's tailed beast after their own reserves are used up.
