Naturehold

Naturehold (浄化技術 (自然所持アート), Rentan Jutsu; literally "Nature Possess(ion) Art") is a technique that is similar in principle to Fullbring, but involves spiritual energy traces of Blanks within Humans.

Overview
Naturehold is a special ability which certain Humans, and even Wholes rarely, are born with. It gives them access to powers that have relation to a specific term that one values above all else. This is done by influencing the "word soul". It was stated by Seireitou Kawahiru that it does not entail a specific word that one is close to, but rather an ideology or concept that they value among all else; even a principle that one abides by. In this regard, it is a much more broad ability than Fullbring, which only allows its users to manipulate the "soul" of matter.

How one goes about developing this power is still a topic of debate amongst the Xanatos Gambit members. It is theorized that a human goes through a horrific experience that actually causes them to regress their memory far back enough, or even when a human develops a strong case of amnesia, they can eventually develop a Naturehold. The same has been theorized for Wholes. However, just as the case of Fullbring, potential Naturehold users would need to have had some sort of contact with a Blank or even a Shinkūmyō's spiritual power. It is possible that traces of either species' spiritual energy was imprinted in their mothers' bodies, which were passed on to them when they were born. Thusly, Naturehold is a power closer to those of Blanks, rather than Shinigami or Hollows.
