Bringer-of-Darkness Technique

This technique creates a genjutsu that exerts an hallucinatory effect upon the eyesight, effectively blinding the opponent. No matter how skilled an opponent may be, they are forced to wait helpless in this world of darkness, as this technique allows the user to attack unseen. Although it negates sight, it does not stop the other senses. In essence, the opponent can hear, feel, and smell out the user of the technique and break its effects by landing one hit.

Trivia

 * In the anime, Tobirama Senju was the one to initiate this technique. However, in the manga, the technique was cast by Hashirama Senju. In the video game Naruto: Ultimate Ninja 3, both are capable of performing the technique.
