In Another World with Truck-kun (Yet Another Damn Isekai Story)

[Inquisitive Raven]

1. If ye wants to be murderin', pillagin' pirates of old, then take it out on thar Jungle Elf's fleet.  The fine folks o'Freeland done gave us Letters of Marquis Marque ("Marquis" is a noble title.) to keep them heathens away from the fishin' fleets, and that suits us just fine.
   
2. No slaves.  Not unless yous be wantin' to test thy sword against paladins. (Ouch, just ouch) 
   

"Yous" appears to be a variation on an Italian attempt to give English a second person plural. "Thy" OTOH is the possessive of "thou" which is a second person singular. Note: it's a familiar pronoun which means it's used with family, close friends, and social inferiors (If you're familiar with Spanish, it's equivalent to "tu.") "You" can be singular or plural, but as a singular, it's considered formal which is to say it's used with anyone you wouldn't use the familiar form with.  Given that captains and crew would be socially inferior to admirals, I can't ding you on that count, but do try to have the numbers and level of formality agree.

The only other form of organized governance are the dockworkers unions, who ensure the smooth operations of ports. 

Huh, "union" seems like rather a modern term. I'd've expected "guilds."
