Maybe it's both; she's normally expressionless (shows in her official introduction), but at the same time, fighting is an intimate part of her being - either to be enjoyed, or just coldly done.

Not entirely sure how her silhouette fits into that yet :/ But either way, she's likely the opposite of Weiss, in the sense that Emerald has tons of practical (real world) fighting experience, but little-to-no practice in actual techniques/training.
