I forget which # eps it specifically comes from, 
but it's certainly from the 2nd season; it's 
from the same sequence as her quick nude shot.  
^^;;  It's when she returns to Arago's castle 
and wears her kimono outfit for the first time 
that you see it.  This is also the scene when 
her true self is trying to fight Arago's 
influence...  Uh, I'm pretty sure anyway.  lol  
Nice addition for any Kayura fan.  =)
