Arc's fights so far have been spamming Blood Hound Step and Moonveil to great effect. Skills aside, we saw the difference in reaction between Arc's reaction to a surprise rear attack vs the mum's reaction.
Not sure, but it's setting the trend of strong female elves marrying and settling down while the trainees go save captured comrades..I wonder what's the deal with Big Sis's betrothal? Is that set up to be some scumbag to save her from, or some off-hand characterization to introduce her with?
Seemingly, "dark elves" are just pink haired elves.
