One Piece: I’m Starting a Rebellion

[Ruthless and decisive + no female lead + Absolute Justice + twisted + uprising + dark justice + spiritual ascension]

What do you think justice is? What is evil?

Does killing make someone evil?

The greatest evil in this world has never been pirates. When people watch the anime, they tend to focus on the Marines and the pirates, and sometimes the World Government, but they often overlook the most fundamental problem in this world.

Only after Ka Lu arrived in this world himself did he understand: what pirates? They're the least of this world's problems.

The real darkness in this world is the system, the government!

Only by rising up and completely overthrowing those feudal bastards can this world truly be liberated!

The protagonist, the Marines, the pirates: none of them matter!
