Europe, early 20th century. Young man meets a mysterious young girl who spends most of her time in a library, reading. There is some friction between the two, with the girl showing signs of being tsundere. No, I’m not talking about Gosick, Dantalian no Shoka just happens to have a strikingly similar setup.
The similarities end there though, with Dantalian’s plot involving magic, monsters, ancient grimoires, and a male protagonist who’s able to take care of himself for once. In the first episode Huey has already shown that he can handle a revolver, killing a zombie-like creature and a magical lion. He also saves the day by reciting a couple of mystical incantations.
