Sealing Technique: Crystalline Chakra Soul

Sealing Technique: Crystalline Chakra Soul  is a kinjutsu used by a few the members of the Uzumaki Clan. It allows the user to seal the entirety of a being chakra, soul, memories, or body into a crystal like sphere. It is deadly to the user ,as if they are not stronger then what they are trying to seal, they will be sealed instead.

The spheres can be used in multiple different ways. Though they where mainly implanted into the bodies of another. Depending on said sphere, it could amplifying their host's chakra powers numerous times, slowing the aging processes of their bodies, replenishing their chakra energies by gathering more from the world, and eliminating the natural needs of their bodies such as nourishment. Despite the improvements they are often fragile and removing them is fatal for the user. As such, destroying the core turns the host into ash in a matter of moments.

It has been stated that attempting to implant two or more spheres is extremely dangerous as few people survive grafting a second sphere on their bodies and, even if the procedure succeds, they have a less than 5% chance of surviving another year.
