I respect your decision to be a pure pirate at heart, without blemishing your traditional pirate's way of life/culture.
I'm a pirate at heart but I have to adapt to the times. I'm willing to amass mixed non-pirate skills to improve my survival, including ninjitsu and sorcery (Kuji-kiri).

I fully know you got lots of beautiful stinky edentulous wenches in your ship; however, are you willing to consider learning some of the ways of the ninja, if the Head Ninja gives you 20 sweet-smelling geishas (make-up, optional) to entertain you? ROFL.
2 nights ago, I was watching "American Ninja Warrior: USA VS Japan." I'm getting disillusioned. I've heard the news of Somali pirates renouncing/quitting the pirate life. I hope the movies I watched when I was a kid, about pirates and ninjas are not cinematographic pieces of bull crap, lol. I hope the pirates and ninjas, in books and movies are not excessively romanticized. I hope I'm wrong...
