However, she grew tired of hiding, so once she mastered the character in to which to seal Doukoku, she assumes her birthright. Kaoru is very kind and generally easy to work with, though, like Takeru, she tends to hold her emotions back. Her retainer, Tanba, often annoys her with his arrogance and she hits him on the head with her fan. Even tough she does want the vassals to follow her into battle, she quickly realizes that their loyalty and bonds are to Takeru; And are stronger than their commitment to her as the true head of the house. She even accepts Genta as a fellow warrior even though Tanba doesn't acknowledge him as a samurai. As a result, she doesn't reprimand them for going to him.
