The user of this technique encrypts a type of Virus into a Genjutsu that destroys the technique from the inside out, thus negating the technique altogether. Like it's sister technique, the Demonic Illusion: Mirror Heaven and Earth Change, one needs the preemptive ability of the the Sharingan to read through an opponent's genjutsu and destroy it in an instant. Comparatively, it also deals a great amount of mental damage to the user, considering the speed at which the Sharingan user is able to counter and destroy a genjutsu. It is also possible for the user to layer their own genjutsu on top of the technique, leading the enemy to believe their genjutsu hit, a phenomenon shown many times by Taiga Uchiha.
