Well, without more information, it's difficult to say precisely. It might be a story that uses the law as a backdrop to explore deeper themes like justice, morality, and power. Maybe it follows a lawyer protagonist who has to deal with complex cases and moral dilemmas within the framework of the law.
The law is definitely not dead in One Piece. It exists in various forms and degrees, and its enforcement or violation drives many of the story arcs. The struggle against injustice and the search for true justice are ongoing themes related to the law within the manga.
Not at all. Law remains a significant character and has many ongoing plotlines associated with him. His presence continues to shape the events in the One Piece manga.
The main elements could be a sharp mind, physical prowess if needed, and the knowledge of when to be ruthless and when to show mercy. A good understanding of the rules of the kingdom and the people's hearts would also be essential.
