From AnimeSuki:Airi's Artificial Sacred Gear's base form is a feather robe (possibly an elegant golden ballet tutu ) She will need to perform a ballet move to reach her Balance-Breaker (Tutu of the Devil is the name of the technique to do it), and yes, the BB form is the golden armor similar to the Vol 20 cover, but the robe stays instead of vanishing.
