Panther Claw, a covert group, wreaks havoc and defies authority in Tokyo. Meanwhile, the police force is left puzzled as a lone vigilante in cosplay appears, thwarting Panther Claw's malevolent schemes and then disappearing without a trace. This vigilante is none other than Honey Kisaragi, the product of the late Professor Kisaragi's experiment. Honey is a skilled master of disguise, capable of magically transforming her appearance and clothing. However, with the press of a heart-shaped button on her choker, she transforms into Cutie Honey: a love and justice warrior, wielding a sword and dressed in revealing attire.
