Korra took deep shaky breaths trying to get herself under control. For a demon it was natural that she would react badly to this. Demons weren`t nice in general but to their own race they hated everyone. Alliances were the only way they didn`t kill each other. As a child Korra herself was hurt pretty bad by other demons, mostly abused by a dog demon who her parents had an alliance with. Being at this academy with some many equal rights made her extremely happy because she could be herself. (Timeskip of about three months? I have a plan.)
