karulau was once princess of na-tunku before the shakukoporu deposed her and placed a puppet leader at the head of the state. she joins hakuowlo after she is found having slaughtered many soldiers from another country who were holding her prisoner. despite showing concern for her country (which she conceals), she has forsaken her past as royalty and decided to live her life as karulau, a simple woman, and as a sign of this vow continues to wear a large metal collar around her neck placed there in her captivity. she is one of the last two giriyaginas on earth, along with derihourai, her younger brother.
