Wood Release Secret Technique: Nativity of a World of Trees

A technique developed by Hashirama Senju, founder of Konohagakure, the user forces trees to grow on any surface, easily creating a dense forest anywhere they choose. A small plant can grow into a forest in an instant. By generating chakra, the user manoeuvres it as they see fit for attack and defence; and furthermore, this omnipotent technique even allows them to capture the enemy at the same time. With their tremendous life force, the trees can pierce through earthen walls, and extend their branches at their prey in an instant. Even stating that Konohagakure wouldn't have been established without this technique wouldn't be an exaggeration.

Trivia
