K-20 Legend of the Mask

In an alternate version of 1049 Japan in which World War II never happened, the Japanese capital of Teito is home to both an ultra rich upper class and the dirt-poor masses. The city is thrown into a state of panic when a phantom thief called The Kaijin (Fiend) with 20 faces (K-20 for short) begins to use his mysterious abilities to steal from the rich and give to the poor.
