Auditore Siblings +Rivalry+

Oh, well. So much for love between siblings. XD Just drew it for height comparison yesterday, but then this came to my head today while watching Kobato (and yes, it's from CLAMP):

Reserve from right-to-left:

Petruccio: Please, stop fighting!
Claudia: I'm telling you, papa likes me more!
Ezio: Yeah, right. He likes me more ten times better.
Frederico: Oh, no. Not this silly little argument again.

I hate my scanner.

Edit: Turns out the only female Auditore sibling's name is revealed and her name is really Claudia
