Ice Release: Piston Fist

Ayane creates alters the version two armor thats encasing her arm to that of a piston-like weapon out of dry ice, which is stronger than steel. Once it connects with an enemy Ayane must dissconnect the piston from her armor for the dry ice effect to weigh the enemy down, and sometimes pin them down.

Ayane has also shown the ability to create this out of normal ice, however it takes longer to create.
