This story takes place after 'Space Officer Leo,' and instead of earth as usual, it's 'starts' on Mars!

A wonderer by the name of Joe, and his little companion he met in the middle of his wonderer journey, work together to find lost treasures and relics throughout the universe, but at the moment reside mostly in Mars.

Unfortunately they aren't the only ones after treasures, as there is a specific space pirate group that they butt heads with constantly.
