This is a genjutsu passed down since ancient times in Konohagakure. The user first disappears from plain sight in a mist-like fashion in order to approach the target without being detected. Once close enough, the target will then be completely robbed of their mobility as they see the mirage of a fast-growing tree coiling itself around them. Given that the subject remains conscious, this technique proves extremely efficient for information-gathering. Once the target is immobile, the user can then attack the enemy, usually after emerging from the trunk of the tree. Though the technique is a powerful one, its effects can be reversed at the user with the power of Sharingan.
This technique was inspired by Hashirama Senju, with the intention of tricking a victim into believing this was Wood Releaseninjutsu, and ultimately scare them into thinking they were facing Hashirama himself.
