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!
It'll take more than that to stop me!

¡Necesitarán más para detenerme!
¡Hará falta más para detenerme!
Ça ne me fait rien du tout !
Ci vuole ben altro per fermarmi!
Vai precisar mais do
que isso para me parar!
Меня таким не остановишь!
