Two girls with nothing but fists and nerve roll into a high school run by ninjas and come out the other side having solved a mystery nobody asked them to solve. The action snaps, real martial artist choreography, not the usual OVA shortcut, and the cast around them is solid enough that you actually care when someone breaks. It's a 1989 one-off that knows exactly what it is: a weekend adventure where two women wreck a corrupt system and move on to the next town, leaving the mess and the broken hearts for someone else to sort out.
Two high school girls with a mission arrive at a prestigious academy where something rotten festers beneath the polished surface. Reiko and Junko have spent their years traveling between schools, hunting down corruption wherever it hides, and this campus harbors secrets darker than most. A corrupt administrator pulls strings from the shadows while a secret ninja order operates in the depths of the school, their loyalty bound to old crimes and older grudges. As the pair investigates, they uncover a tragedy buried decades ago, one that shaped everything happening now. They're not alone in the fight. Kotetsu, a ninja caught between his order and his conscience, becomes an unexpected ally. Together they battle through schemes and combat to expose the truth, though victory comes with costs none of them anticipated. By the time the dust settles, the school is cleaner, but the emotional wreckage lingers. Action-packed and surprisingly poignant, this OVA pairs martial arts thrills with genuine character stakes, delivering a story where winning the fight doesn't always mean everything works out neat.
