Kaidou is a merciless, aggressive, and confident warrior who never misses an opportunity to gain an advantage in war. She suffers from bouts of apathy and boredom, harboring a general sense of unconcern for most things including the very nature of the world and the lives of herself and her subordinates. She keeps a grumpy disposition with little pleasure and excitement in her life and is constantly frowning most of the time. As such, she craves excitement and chaos.
