Renkin 3-kyu Magical? Pokahn (錬金3級 まじかる？ぽか～ん, Renkin San-kyū Majikaru ? Pokān?) is an ecchi anime series that tells the story of the everyday life of four princesses from the fictitious World of Magic (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.
