Maya Yokoo

Maya Yokoo, the second third-year student on the team, is a competitive and tall girl with more team spirit than anyone else in her team. Maya is a bit of a tomboy and tends to speak in a rather aggressive and foul-mouthed manner, calling her teammates "twits" and "dumbasses" when they do not take kendo seriously. However, she will stick up for her teammates when Yūri says cruel things about them (or rather, Akemi), as shown in two episodes of the anime. Apparently she also seems to have a rather large appetite that causes her to eat so much that she ends up with a severe stomachache later on.

Tamaki beat Maya during the last round of the practice match with Muroe High, much to the latter's displeasure and shock. source: wikipedia
