In the mad mad world of Daimon High School, physical education lords over academic enlightenment, extracurricular clubs elbow out curricular classes, and disagreements get settled mano a mano in the K-Fight ring. At the prompting of eccentric sophmore transfer Shizuma Kusanagi, the equally eccentric Principal Todo sanctions the K-Fight program to settle disputes, much to the chagrin of Daimon's best martial arts master, Ryoko, whose reverence for the craft drives her to loftier ambitions - justice, duty, and being a great woman. However, she can't help but get wrapped up in a brawl or two even as she secretly pines for the fair, and hardly flirty Tatsuya.
