The user places a hallucinatory darkness on a target's eyesight, causing them to see nothing but black; Tō no Sho likens the sensation to being at the bottom of a deep hole. Because the target cannot see, they are very vulnerable to attack. Although this handicap is dangerous even to the likes of the Third Hokage,[1] it is not insurmountable, as the Third is able to sense attacks to try to defend himself and smell his attackers in order to stage a counterattack. When the Third finally captures the user and begins removing their soul, the darkness disperses, something that Orochimaru, an onlooker, immediately notices.[2]


  • The full name of this technique is Genjutsu: Bringer-of-Darkness Technique (幻術・黒暗行の術, Genjutsu: Kokuangyo no Jutsu, literally meaning: Illusion Technique: Bringer-of-Darkness Technique).
  • In the manga, this technique is performed by Hashirama Senju. In the anime, it is instead performed by Tobirama Senju. In Naruto: Ultimate Ninja 3, both are capable of performing the technique.
