Durandal was shown to be mature, quick at making decisions, and a little hot-headed when she was 12. Theresa states how she would often lecture senior officers on the importance of hard work whenever they tried to take a break, much to her dismay. She is also somewhat gullible. As she fell for Kiana and Theresa’s “vacation” excuse when they ratted her out to Anti-Entropy to buy time. Durandal is overall a kind person who is dedicated to saving lives and her duty as a Valkyrja.
