Wood Release: Wilderness of the Rainbow's End

Said to be the ultimate defensive technique of the Wood Release. By using the wielder's ability to grow vegetation on any surface, the user creates an arc of intersecting trees, enveloping the user from all sides. The type of trees used as well as the arrangement of the vegetation makes the resulting shield incredibly durable, to the point of many labelling it as virtually indestructible, as not even a barrage of Tailed Beast Balls was able to make a dent within the trees. It is these properties that lead to it being one of the few technique to be labeled as an "Absolute Defense" (絶対防御, Zettai Bōgyo).

Trivia

 * The techniques name comes from the Nijinomatsubara forest in the Saga Prefecture. The strong defensive properties is a possible reference to how the forest was planted by the feudal lord Terazawa Hirotaka in an effort to stop the strong winds and ocean tides in Karatsu Bay.
