Quote:
The four princesses, Uma, the witch, Pachira, the vampire, Liru, the werewolf, and Aiko, the android, came to the human world from the magical land by some reason. One week has passed since they began to live in a hut looks like a bird’s nest on a big tree. Because they were not accustomed to the human life, their life was in a mess; Liru was about to be shot a shiver bullet, Pachira turned into ashes, Aiko was infected by virus, and Uma exposed her chest in public.
