The shinobi receive a mysterious message delivered by arrow from an unknown, and potentially deadly, assailiant who lurks in the shadows. The letter lures them to an empty spa resort, where they'll begin a trial like they've never faced before. But first, it's time for everyone to have a squirt gun fight in skimpy swimsuits!
Let's have a fair fight!
Auf einen guten Kampf!
¡Empecemos!
¡Empecemos!
Merci pour le match.

Vamos ter uma luta justa!
