My first impression of Lady Aska was sort of .. disbelief .. I guess? Like an over the top spoiled kid I just could not take her seriously and thought she was hilarious! :P Later on though, I grew to respect her strength of will, and believe it or not, her open-mindedness. Much to my surprise, she was the first one of Cephiro's enemies to make peace with them. ^_^
And you're right she really is adorable, her crush on Sang Yung is soo cute! ^_^
