Yin Sealing Method

The Yin Sealing Method is a Fuinjutsu created by Uematsu Tomi to disrupt/nullify Yin Elemental Chakra that does not belong to the caster. He is able to apply it via a single touch. It is effective against sealing against Genjutsu, as it can be set prior on the body to activate upon the recognition of foreign Yin Chakras from entering the body. A single seal can only recognize/isolate the Yin Chakra from one external factor. It will not protect a person indefinitely from all Yin Chakras and can be negated by either causing a burn on the site of the seal to erase it, cut off the part of body where it's located, and so forth. Hypothetically, it is possible to place this seal onto a target to disrupt their ability to mold Yin Chakra/prevent them from using abilities which rely on it.
