Moretsu Uchuu Kaizoku

モーレツ宇宙海賊

Marika is a first year high school student living in a far away galaxy known as Uminoakeboshi. One day she finds out that her recently deceased father was once the captain of the space pirate ship called the "Bentenmaru". More importantly, the only one to inherit the captain's title has to be a direct descendant—meaning that Marika is next in line to become the captain of the ship.
