Renkin San-kyuu Magical? Pokaan

Синопсис:

Renkin 3-kyū Magical? Pokān (錬金3級 まじかる?ぽか～ん) is an anime series that tells the story of the everyday life of four princesses from the Makai who are oblivious to the happenings in everyday life in the human world. The name of the anime is often shortened to Magipoka. The opening sequence of the anime is deceptive to the viewer as it is not apparent that the anime's genre is comedy.

Plot:
There is no plot continuity to this anime, but the story depicts the misadventures of four princesses from the Netherworld: Uma the Witch, Pachira the Vampire, Liru the Werewolf, and Aiko the Android along with their invisible chaperone Keimie. These princess are adapting to life in the human world (though three episodes are loosely connected to each other) and reside in their Garakuta House (a makeshift treehouse complex with the name being a homage to the author of the same name) in Hikarigaoka (a fictional Japanese city that's not to be confused with Hikarigaoka Station). The girls are faced with small self-centered problems such as finding a boyfriend, blending in to society, learning about Earth's cultures, and staying one step ahead of scientist Super Doctor K-Ko.
