Type: Body Adaptation
Restrictions: Must have Shikotsumyaku DNA.
Description: This is a specific body modification that can only be done onto someone with the Shikotsumyaku Bloodline, because of the unique way that it works. The process for creating this body modification involves a Shikotsumyaku user to create the specific notches/pieces needed with their KKG, while the medical mind involved uses a series of concoctions and serums to bind them together and create a neural/tendon system inside of the tail. Combining both aspects together, the finished project consists of a long tail that can be medically attached to a Shikotsumyaku User at the spine, being 1 meter in length and 2 inches in width.
Mechanical abilities: The implanted tail counts as a weapon the same rank as the user, ranking up with them as they get stronger. This also allows the Shikotsumyaku User to create/use jutsu through their tail, like they would a normal part of their body. If the tail is removed somehow, it will eventually regrow(After the thread it was removed).
