Beautiful and excellent theory!
I love how simple this idea is and how well you died together open stuff. I always wanted to make a Dragon Tattoo analysis and you stole my dream! Great job I love it! I just would have called it something like "BEHIND THE CURTAIN: MONKEY D DRAGON" XD refering to the title of my Katakuri tattoo analysis.
Joke aside, the Road Poneglyph theory looks not so strong to be real, but the potential, impact and neccessity is super strong and it's worth hyping and observing that idea!
The Ryuma parallel is kinda a rumble, but tbh the complete context of the theory is making up for it! I just hope all this missing puzzles will make sense!
