Bringer-of-Darkness Technique

A genjutsu which exerts an hallucinatory effect upon the eyesight, stealing all light away. A world of darkness, as if a thick, jet-black curtain had been dropped. No matter how skilled someone is, they have no option besides turning into sitting ducks. This effect allows the user to attack unseen. Although it negates sight, it does not stop the other senses. In essence, the opponent can sense, hear and smell out the user of the technique and break its effects by landing one hit. In the anime, Tobirama Senju was the one to initiate this technique. In the manga, it was Hashirama Senju.
