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!
If you don't want to get hurt...
Wenn du nicht …
¡Si no quieres lastimarte, desaparece!
¡Si no quieres salir
malparada, desaparece!
Si tu ne veux pas…
Se non vuoi farti male...
Se não querem acabar feridas...
Если... не хочешь пострадать...
