Amenokoyane

The Amenokoyane is a visual technique employed by Densetsu. The last time this jutsu was even heard of was during the warring states period. The Genjutsu was a particularly fierce one because when cast, a victim would not be able to break out of it unless he knew of the jutsu, or saw it being cast.

Overview
The technique is very similar in usage and power to Tsukuyomi, only it takes place in the actual world. This fact means that the opponent usually does not know he's under Genjutsu. The effects of the virtual attack also takes a mental toll on the victim, making every second in real life feel like a minute in the illusion.

With enough skill and mastery, a user can use this technique even while not having the Sharingan active. Densetsu relies on very basic but violent virtual actions, to keep the illusion of reality going.

Usage
The key to this technique was to not allowing the opponent to even find out that a Genjutsu attack was coming. Once cast, the vision cast by the wielder is so realistic, it causes the victim to actually scream and roll in pain; exactly as he is doing in the vision.

Densetsu used this technique to escape from Danzō. After trapping Danzō in a barrier, Densetsu immediately resorted to this technique to prevent Danzō from using Izanagi. The vision comprised of Densetsu reaching through his own barrier to grab Danzo's Sharingan out, preventing Izanagi to be cast. The illusion was so real, Danzō rolled and writhed on the ground, actually falling for the illusion. This bought precious moments for Densetsu to escape to safety.
