Bringer-of-Darkness Technique

This jutsu makes a range of darkness that only the user is able to see through, disabling any targets in its range the ability to ses. It does not effect the other sences though, and the jutsu is able to be discontinued by inflicting harm on the user of the jutsu. Tobirama Senju was the one to initiate this technique. In the manga, it was Hashirama Senju.
