Venus Versus Virus

Venus Versus Virus follows a young girl named Sumire Takahana, who has been able to see ghosts since she was little, though no one believes her. One night, while running to her dorm to beat curfew, a brooch comes out of nowhere and she pricks her finger on it, then sees a demon. All at once, another girl in gothic lolita clothing shows up carrying a huge gun and kills the demon. After it is over, the girl hands Sumire a flier for a local clothing store, Venus Vanguard. When Sumire visits the store, the girl, whose name is Lucia Nabashi, explains that because she pricked her finger on Lucia's brooch, Sumire can now see demons as well as ghosts. On top of that, Lucia wants Sumire to help her rid the world of these demons, called Virus, that threaten to consume all of humanity.
