After reading the comments so far, I guess that I 
have noticed a few things.  There DO exist 
Ifurita cels from the original OVA that are not 
very detailed; but these are usually of her in an 
action sequence (where there's a lot of movement 
and the animators need not be so detailed).  Of 
course, Yann probably would instantly forget the 
bad cels.

Okay, how about I post a few images and tell me 
what your expert opinion is?

#1 - This is an example of an action shot which I 
am guessing came from the first OVA (just because 
of the purple-blue flames that were 
characteristic from the first OVA).  But what do 
you think?
