Demonic Illusion: Eternal Hell

Demonic Illusion: Eternal Hell is the most powerful gejutsu in Kuukoyo's arsenal. Compared to most of her other genjutsu, Eternal Hell is different because it remains unbroken as long as Kuukoyo decides to keep it up or the victim manages to gather enough willpower to break through the illusion.

Demonic Illusion: Eternal Hell is capable of wretching the victim's perception of the world in any ways; however, the illusion always will change the victims preception so that he or she will see the world as his or her worst nightmare. This includes making the victim see his or her loved ones dead etc. If not broken, the effects of this genjutsu get increasingly worse, until the world has became a living hell for the victim.

The main weakness of this jutsu is that it can only be casted once on one person; if that person manages to break the genjutsu once, Eternal Hell cannot be casted on him or her ever again. However, this jutsu is very hard to break. The breaking gets increasingly harder along with the jutsu progressing, and the slow, creeping nature of this genjutsu can make it har for the vitctim to realize he or she is in a genjutsu.
