Mirrors Used by the Sailor Senshi
Minako Aino's compact had a mirror in it and it only showed the true forms of those who were reflected in it, so it could be used to reveal disguised Dark Agency agents and always showed Minako's reflection as Sailor V. In the Codename: Sailor V Sailor V used it in many of her attacks, especially Crescent Beam and the more powered up versions of Crescent Beam which utilised light reflected by it. This item only appears in Codename: Sailor V and in the Sailor Moon manga.
