Now coming to grips with his new life as both a male student and a female Kampfer, Natsuru Senohas one problem: Kaede Sakura, the girl that he loves, is in love with the female version of himself! And to make matters worse, the president of the student council Shizuku Sango (who just happens to be a red Kampfer, Natsuru andAkane's sworn enemy) has kidnapped poor Kaede and challenged Natsuru to a fight! Desperate to save the girl he loves, Natsuru agrees to the fight but he (along with Akane) have no idea of how to win against Shizuku and her powerful Schwert-type Kampfer abilities. When Disemboweled Tiger suggests that they go and find Kaede, Natsuru begins to plan out how to save her without getting involved with the fight Shizuku wants.
Pulling this task off means turning to Natsuru's male friend Kanji to gain access to the girls side of school in order for Natsuru to begin his search of where Shizuku has hidden Kaede. Can Natsuru and Akane defeat their sworn rival at her own game as well as free the kidnapped Kaede. Will Natsuru's life-long friend Mikoto discover his secret female identity? Or will both Natsuru and Akane fall victim to the deadly blades of Shizuku and die at her hands?
