Young tiger spirit Sebin wants nothing more than to join the Thousand World Space Forces and captain a battle cruiser. But when their acceptance letter finally arrives, it's accompanied by the shocking news that their uncle, Captain Hwan, has been declared a traitor, having abandoned his duty, stolen the magical Dragon Pearl artifact, and gone AWOL. Sebin hopes to help clear his name and restore honour to the clan, but as soon as Sebin arrives for orientation, they are met by a special investigator, Yi, and Yi's assistant - a young fox spirit named Min, and everything goes wrong when the cruiser is sabotaged.
