This was one of four Shamanic Princess cels I 
purchased six months ago, without really knowing 
where this cel was from in the series.  After 
some helpful suggestions of where it may be from, 
I found out that it is from the OVA 6 preview, 
which is included on the Region 1 DVD release of 
the series.  This cel had grown so much on me, 
that it was the first cel that I had framed a 
little over a month ago; and now she "floats" on 
the wall over my computer.

The cel has no background, the yellow was added 
by me, as it is nearly the same color used in the 
shot.
