The special technique of the Nase Clan, the Glaciate Barriers allows the user to generate a barrier that can be used to either defend against incoming attacks or trap and isolate opponents within.
The barriers also have the ability to "disguise" objects or people, rendering them invisible depending on the user's whim.
Higher level users of the Glaciate Barrier can also encase or "sink" things. This skill was most used by Izumi, in which she first experimented on her secretary and "sunk" her consciousness into a limbo-like state and later used it on Akihito's human side during The Calm.
Appearance wise, Glaciate Barriers are blue in color, their most noticeable characteristic being the moving panels that make up the barrier. They also have a tendency to glow as well as produce ice-like shards within its radius.
