Cosplay Apprentice Pirates (コスプレ見習海賊, Kosupure Minarai Kaizoku) is the third volume of the Miniskirt Pirates light novel series.
A cat-monkey which was infected with a pathogen escaped from its bio-container when Bentenmaru was transfering it to a hospital ship - all of the crew members except Marika caught a transmittal disease and had to be quarantined. If no pirate activies are performed in a month, the Letter of Marque will be rendered invalid. At the peak of her frustration, Marika recruited the members of the Hakuoh Academy Yacht Club to perform the pirate activities on Bentenmaru. The light novel series' third hit, with a girls pirate legion wreaking havoc in space.
