Some observation of the real life appearances of the cast.
WOW, Mireille really is as young as she acts. (Which makes comparisons between her and Mistral interesting.)
Looks like both Ouka and Hotaru are COMPLETELY different in real life.
Ouka looks like Yomiko Readman. Eyeglasses, slightly shy looking, long skirt.
Hotaru looks very out-going and somewhat of a tomboy. (Like an older Sara from Love Hina.) Baggy shirt, baseball cap, two different "cool" necklaces and shorts. Also note the completely uninhibited facial expression. The Puchigoso/Grunty on her bag is a nice touch, sorta like Tsukasa's Macha keychain.
