Saigyoku Nijigasumi

is a technique of Maki Ichinose's Zanpakutō, Nijigasumi.

Description
A multitude of twinkling lights appear and coalesce around an opponent, creating a huge sphere which engulfs everything within a significant radius. Anyone within this radius will potentially get caught in it. Immediately following this, the sphere collapses in on itself, using the compressed light to crush everything within it. Only a strong enough Reiatsu can push back and destroy this technique.
