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!
We'll keep our guard up at all times.
Wir werden wachsam sein.
Siempre estaremos en guardia.
No bajaremos la guardia.
On ne va pas baisser notre garde.
Terremo alta la guardia per tutto il tempo.
Estaremos atentas o tempo todo.
И всё время будем начеку.
