Genjutsu: Ultimate Binding

This is a Genjutsu in which the user preforms the required hand seals, then the target sees total darkness which surrounds the target. Then a cage appears around him, four chains appear from the cage grabing the target's limbs, two from the top of the cage which grabs his arms and two from the bottom of the cage which grab his legs. then the darkness disappears and very intense flames come out from under the cage, the flames' intensity is so high that it turns to purple.

The problem with this genjutsu is that it needs a massive amount of chakra and concentration as it has a lot of hand seals if the hand seals' sequence is interrupted then the user has to start over.
