In a school where martial arts are standard curriculum, Ryoko Mitsurugi, the Samurai Girl, is the top fighter and the most popular student around. This changes when the uncouth Shizuma Kusanagi transfers in from Kansai. He may not have the grace of Ryoko, but with his amazing fighting abilities, he could soon be the most dominant martial artist at Daimon High. Principal Todo encourages the rivalry between the competitors, setting up an exciting K-fight tournament where even the teachers can join in and settle once and for all who's the top dog on campus.
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.
With Tatsuya's transfer imminent, Azumi frets, Shiori shudders, and Ryoko is struck with a sudden dizziness that interferes with her ability to fight. Her feelings for the Kendo Team Captain run deep, and his departure means that her reason for fighting is going to have to shift from making him proud to building confidence in herself. And Principal Todo longs to turn Ryoko's misery into K-Fight entertainment by having her next bout filmed by stalker-in-training Daisaku. Daimon High School, where brawn beats brains, may very well get turned upside down.
Daimon High School's student council president Isozaki asks martial arts expert and fellow classmate Ryoko to collaborate on an effort to sweep the streets clean of troublemaking scum. But his hidden agenda is clear: he wants to expand the K-Fight program beyond the school's campus, and does so by pitting Ryoko and four other women warriors against Shizuma and his band of brawny brawlers. Surprisingly, Ryoko not only accepts the challenge but agrees to head the group of lady fighters as well, hoping the experience helps her attain her ultimate goal of becoming a great woman. The battle of the sexes is, literally, at hand.
Ryoko Mitsurugi and Shinsengumi are expected to kick some serious ass at Dragon Land, but they're nowhere to be found. All wait in baited anticipation: the K-fight news team, the Daimon High School student body, Principal Todo, the Isozaki triplets, and the ominous "G" who has already given Ryoko one thorough pummeling and now plans to video tape her K-fight matches to sell ont he black market. With the arena set and the opponents ready to rumble, all Shinsengumi has to do now is show up!
The Daimon High School spectacular will be concluded mano y mano in a group of magnificent melees and explosive exchanges: After stopping Project Z, Ryoko loses her memory; the battle between "Shinsen-gumi" and "G-gumi" goes to the second round; and the battle of Ryoko vs Shizuma just might go the distance. Nobody pulls a punch in the no-holds-barred final installment of this butt-kicking-and-name-taking series!
