Demonic Illusion: Butterfly Dream

A that is not used solitary but rather to augment or sustain an already-existing one, developed by Shisui Uchiha. When the victim of said pre-existent illusion remarks he is in fact under the effects of one, he will attempt to break it. Depending on the skill level and determination of the opponent and the complexity of the genjutsu, this may or may not succeed. When the user notices there is a very likely chance of his opponent breaking free from the genjutsu, he may infiltrate his opponent's mind within the already-existing genjutsu. The influence of the is needed as to not disturb the workings of the original technique. After having done this, the user creates the illusion of the previous genjutsu having been broken, giving the victim a false sense of security, making them even more susceptible to the original illusion.

Should the opponent still see through the user's tactics, this technique can be used time and time again, until the opponent can no longer differentiate between illusion and reality, possibly even causing permanent mental damage.
