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!
But don't think this
is how it will go next time.
Pero no crean
que así será la próxima vez.
Pero no creáis
que la próxima será igual.
Però non credo che la prossima volta
andrà allo stesso modo.
Mas na próxima, não acabará assim.
Но в следующий раз такого не будет.
