She has a weakness for cute animals and is a lightweight when it comes to alcohol and hot baths, over-heating and passing out easily if subjected to either.
After being Hakuoro's enemy for a while, she pledges fealty to him in order to redeem herself for the injustices, taking the role of Hakuoro's bodyguard.
