Eye catching animation paired up with lots of action scenes leaves just enough space to flesh out the main characters. The story follows a cat/spirit named Hei as he is thrown in a conflict between 2 factions of spirits and humans. At first the main plot might seems like nothing special, but the line between good guys and bad guys quickly gets blurry as both side have fairly convincing motivation for their goals. The main characters might seem overpowered at first while actually being fairly evenly matched against each other. If you like fight scenes then you can not miss this one.
