Ranshi - Burning to DeathEdit
Ranshi is a genjutsu technique which can be used in quite a few ways. The user forms a handseal, and as long as the opponent(s) see it, then the genjutsu will begin. The user and the opponent(s) will both light on fire and start to burn, from the feet up to the head, in the opponent's mind. Surely, you can guess that the opponent will normally start to freak out and try to get rid of the fire.
