As much as I *love* my entire "Weiss Kreuz" 
collection dearly, and have some others I am so 
incredibly attached to, I'd have to say my 
favorite is...

... These two! Sorry, I couldn't possibly pick 
between my two *favorite* beloved anime 
characters of all time!! *^_^* I know I've shown 
off my pan cel of the Frosts here before, but 
it's *still* the cel of Olba I constantly drool 
over!! It's those gorgeous eyes!! And I'd never 
EVER part with my one and (unfortunately) only 
cel of Nagi Naoe!! I LOVE BOTH SOO~O MUCH!!! 
They're my precious treasures as far as cels go!! 
*^_^*
