Five girls piloting giant ninja robots in a virtual city sounds like a fever dream from 1995, and it is, the kind of premise that only existed because nobody was saying no yet. The OVA commits completely to its absurdity without winking at the camera. You get exactly two episodes to fall in love with a team dynamic that feels lived-in, mecha action that doesn't need to justify itself, and a villain origin story that actually tracks. This is what happens when a show trusts its own weirdness.
Five high school girls come back together as Sailor Victory, a secret group of vigilantes that fights crime in Mikado, a virtual-future city on the distant planet Totsu Asuka. Crimes committed with armed robots are rising, and the city police are poorly equipped to stop them. The team commands three giant ninja robots named Gion, Momoyama and Sagano. With its reputation sinking, the police force will go to any lengths, fair or not, to look better than Sailor Victory. Meanwhile a disgraced, resentful city official turns to evil and allies himself with the sinister Margarita. The mecha and science fiction OVA runs two episodes.
