Saigyoku Nijigasumi

is a technique used by Maki Ichinose's Zanpakutō, Nijigasumi.

Description
It causes a multitude of twinkling lights to appear, which then form together around an opponent, creating a huge sphere which engulfs everything within a significant radius. Anyone within that radius will potentially get caught in it. Immediately following that, the sphere collapses in on itself, using the compressed light to crush everything within it. Only a strong enough spiritual pressure can push back and destroy this power.
