The Tyrant Marine of the Grand Line

Karl transmigrated into the world of One Piece and activated a pay-to-win System.

As long as he spends money, he can get stronger.

There's no problem that spending money can't solve. And if there is, just spend more.

Since paying to get stronger is an option, the rest is simple.

All he has to do is rake in cash.

To make money more effectively, Karl joins the Navy, smuggles weapons, takes control of shady businesses, and collects protection money from islands.

"I opened this mountain, I planted these trees. If you want to pass through, pay the toll..."

"I don't care if you're Navy or pirate, one of the Four Emperors or the World Government..."

"Every last one of you is paying me protection money..."

And so, a bully of a Navy officer appeared on the Grand Line.
