The shinma often have a "prettier" form which you 
see until they fight Miyu - that's Moru's "pretty"
form. I think I have her true form on a trading 
card (which I can scan if you like) but below is 
my only cel of one of the shinma in their true 
form. It's the one from the idol singer episode 
and was an unknown cel on Ebay. ^_^

He's one of the coolest looking true forms. It's 
tough to see in this cel, but he has three legs 
(like a piano) and his wrists and hands float 
separate from his arms. It's not a critter you 
forget quickly. ^_^

If anyone has Vampire Miyu shinma cels they don't 
want. . . (*waves some money temptingly!!*) ^_~  
I'm so out of luck trying to collect them since 
dealers never recognize them.

Many Sharp Smiles,
