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!
I was getting sick of waiting.
Endlich!
Non ne potevo più di aspettare.
Eu estava cansada de esperar!
Надоело ждать.
