A third-year student at a suburban junior high school. Headstrong and having a penchant for mischief since childhood, everyone back in kindergarten looked up to her as a boss. Because Aoto and their mutual friend were much more tame in comparison, she was seen as the boss of the trio as well. Upon starting junior high, she'd considered joining one of the cultural clubs at first, but after being wholly impressed with a kendo demonstration while passing by the dojo one day, she became determined to pursue the art of the sword.
