Opening NarrationEdit

"In outer space, there isn't an absolute left, right, up, or down. It all depends on your relative position. Understand where you've come from and where you're going, which way you're facing, and you'll know your current position. Confronted by the vastness of space, you may be disoriented by how small you are. But overcoming that feeling is your first step in outer space."

Next Episode PreviewEdit

"A mysterious, armed vessel lies in wait. Do the yacht club's frail members have any chance to win? They use all their weapons to the best of their abilities, and their resolve opens the way. What is it that Marika sees then? Next time, on Mouretsu Pirates: Marika Makes a Decision. Look forward to it."

Ending QuoteEdit

"Breakfast beats worrying."
