Blood Release: Unholy Regeneration

Description
With the use of one’s chakra towards their wound, they can use the Unholy Regeneration technique. This technique can also be considered a twisted version of Medical Ninjutsu, as it involves using one’s blood to fuel their healing process. What was gone can be restored, given enough chakra is put into the restoration.

Usage
Using his chakra to create a copious amount of blood, he then uses it pretty much completely regain a lost piece of his body. This regeneration even counts towards lost bones and any Fūinjutsu, before the injury occurred. This regeneration is mildly damaging to the soul, in large amounts. Something small, like fingers, organs, or skin, are nothing. Those that have become Immortal will learn that they are generally immune to the negative effects of the entire Kekkei Tōta, effectively capable of using this and other techniques with recklessness.
