Aron's Absurd Armada Vol. 1 (manga)

We are pirates…
Yup, we are totally pirates…
Whatever anyone may think, we are definitely pirates…
We have a captain, a crew (?), and even Robin, so we are absolutely pirates…
Captain Aron is a brainless idiot, and Robin only loves money, but we are still pirates…
Sailing in search of treasure (or not), we are unquestionably pirates…

So, in conclusion, we are pirates…!
