Hyōga Seiran

is an anime-only Kidō spell. It is used by Kōga Kuchiki during his battle with Byakuya Kuchiki during the Zanpakutō Unknown Tales arc.

Description
This spell fires a massive wave of ice capable of freezing its targets and surrounding area. It is seen to be strong enough to destroy a group of Menos Grande through sheer power. It is also strong enough to go through Danku, which can block any Destructive spell numbered 89 or less, although it took around fifteen seconds to do so.
