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!
There's no point in wearing a swimsuit, then!
Dann bringt mein Badeanzug nichts.
Entonces, no tiene caso
el traje de baño.
Entonces el bikini me sobra.
Autant se passer du maillot,
dans ce cas.
Allora non ha senso mettersi in costume!
Não há porque usar
roupas de banho então...
Тогда и незачем надевать купальник.
