Jikkaigogu

Users of this puppetry ninjutsu manipulates the body of a target on the fly. The user binds his soul to a summoned ethereal entity to be manipulated at will. Once the body's rendered empty of the caster's spirit, the entity then manipulates the body, like a marionette. All of the wielder's jutsu remains accessible in this state, yielding a combat capable synergy of both the Ikiryō and the user.

Background
The Batista's notoriety as a fūinjutsu and juinjutsu specialist spread across the land in the war torn era. Enemies feared his skill sets and attempted to assassinate him. They were nearly successful. However, Batista survived and sought a better method of dealing with opponents. Puppeteers played a significant role in attempts on Batista's life, as did jinchuuriki. Batista gleaned from these attacks a seed of an idea. He developed concepts of binding one's soul to a possessing entity in order to move one's body as a puppet. Seeing a weakness in combat sealing methods that his clan became known for, Batista Kittu invented this particular style of puppetry to compliment senjingan sealing techniques.

Execution
Sōrei Ningyō-hō: Jikkaigogu (十界互具:騒霊人形法, Poltergeist Puppet Method: Mutual Possession of the Ten Realms) Modified jutsu that allows the user to summon and possess a ethereal creature, who then takes possession of the body of the summoner. This process is known as Ikiryō-tsuki, "Living Ghost Possession." The user controls the creature who controls the user's body, hence "mutual possession." Batista considered this a form of self-puppetry as the body is literally manipulated like a marionette by the ethereal entity, whom the user manipulates in turn. This renders the user immune to the effects genjutsu and physical injury at the cost of debilitating damage upon jutsu's end if the body encounters serious injury.

Risk
If the user's chakra level falls below that of the Ikiryō, he will remain unable to to control the entity and will become permanently possessed by the creature, unable to control his own body. To prevent this, chakra is drawn from the Ikiryō and converted for use in the casters own jutsu doubling the amount of chakra the user possesses. However, if this is a delicate procedure. Any mistakes on the user's part, and perpetual possession becomes imminent. As this jutsu is primarily a combat technique the danger remains omnipresent during engagement of an opponent.
