Jutsu
1. The activation of the jutsu relies on the target looking into Sin's eyes, or at his finger. The enemy will experience the five hells. First the victim will begin to burn from the feet up unable to move. Once completely burned they will reform. After reforming they will begin to suffocate covered by water. After this the water will evaporate. From above will fall multiple jagged stalagmites to crush and pierce his opponent. Appearing in a area of pure dark lightning will strike them burning them and frying their body to a crisp. Once again they will reform in the same empty void. A slicing vortex of wind will then converge on the victim to slice and chop at their body. The jutsu will be completed in about eight seconds in reality, but it will feel like hours of torture to them.

2. The victim will experience an out of body experience where their conception and realization speed are tampered with. Everything in their eyes and mind contradict one another. It takes them, what feels like weeks, to take a number of steps forward, along with every other sensory sense; they smell things late, see things unravel slowly, hear things slowly, taste and feel things in unpunctuality. When they are put in pain, they feel it sooner than they see it. This Genjutsu is considered forbidden, ranking higher than Tsukiyomi. This technique, if put on a weaker mind, can result in permanent mental damage, resulting ultimately is a permanent state of psychosis or paranoia. This Genjutsu is highly renowned as the "Reverse Sharingan," in which everything one does is perceived slower, rather than seeing the opponent's moves unfold slower.
