This technique, which seems to be Crystal Release: Crystal Pentagonal Prison on a smaller scale or a minor version of it, allows Guren to completely encase a single target in crystal. If the crystal is shattered, the victim disintegrates along with the crystal particles. However, Hinata was able to surround her body with chakra before she was completely encased, thereby avoiding the disintegration effect. Therefore, this jutsu has no effect on chakra.
