Four supernatural girls move into a human apartment and immediately break everything they touch. The comedy isn't about their powers or their origins, it's about a witch who doesn't understand how to use a washing machine, a vampire who keeps getting sunburned because she forgets to check the weather, a werewolf whose strength destroys furniture on accident. Every episode is just watching the most powerful creatures imaginable fail at grocery shopping and accidentally traumatize their landlord, over and over, until you realize the running gag is that nobody in this show has learned anything by the next episode.

Four supernatural princesses from the Netherworld have relocated to the human realm, and they're hilariously unprepared for normal life. Uma the witch, Pachira the vampire, Liru the werewolf, and Aiko the android set up home in a hut resembling a bird's nest high in a big tree, and their ignorance of human ways turns everyday life into a mess. Mishaps range from a close call with a silver bullet to a computer virus and an embarrassing public exposure. Complicating their accidental comedy is Dr. K-ko, a scientist obsessed with proving the supernatural exists so she can win acceptance among the scientific elite. She's determined to capture the princesses as evidence, but her schemes have a habit of going wrong. The show mixes comedy with ecchi humor across its 12 episodes.
