Water Release: Crushing River Technique

The user first surrounds their target with a large ring of water, then causes the water to compress, crushing their target. Instead of crushing the target, the user can also lock their target's limbs in place, allowing them to be taken prisoner. The user is also able to control the increase of pressure, allowing them to kill the target quickly or slowly, making this technique a useful torture technique.
