Karen Nishiyama

Karen Nishiyama, the third third-year student on the team, is incredibly skilled at kendo, but tends to shake when nervous. When she is cornered in a kendo match she instinctively switches to the offensive, thus effectively beating her opponent. Because of her instinct of going on offense when in trouble Karen is the strongest on her kendo team. Even though she is extremely skilled at kendo, she does not like the idea of fighting an opponent that she does not know in real life, and she will attempt to run away when she is nervous. source: wikipedia
