In a certain city, a young little girl appeared one day, but she was no normal - she had pink skin, dark pink hair, a pair of cute little horns protruding from her forehead, black eyes with golden irises and slit pupils, cute little fangs, small bat-like wings, a spade-tipped tail, clawed fingers and toes, a forked tongue, and a devilish grin on her face!
This little imp has infected all she sees, and only by asking "Will you play with me?", and try as her victims might to resist, they become little imps too - ready to play with her, and make more people into naughty little imps!
Those who get turned keep their memories and intelligence, for it makes it easier for them to find new "playmates"!
This cause panic among the still-human population, and the city was sealed-off, leaving the survivors trapped inside with the imps!
The imps plan to leave the city to turn others, but only after they finish the job here.
This story is about a survivor who's trying to take refuge and hide from them, but who?
