There's something weird about her first BnB pulled off in the vid. The part after the kick launcher, there's a part in the combo where the dust cloud on the floor comes out and there's even the sound of a character slamming the ground, which means that Akiha got groundslammed in the combo, yet why can Ciel knock her into the air?
Also, she seems to be slightly incomplete. She doesn't have a proper death cry. Or maybe that soft, normal-sounding squeal IS her death cry. Not that it's important, but something I noticed. There's also a metallic sound when she Ex-Guards something. Or is this universal to all characters now?
EDIT: The metallic sound seems to be universal. In the second fight against F-Seifuku, the sound plays when she Ex-Guards too.
