Do you think Imu is earth klabautermann? Do you think Imu real name is Mary joy or something? Do you think it connect back to strawhat ship going merry?
Klabautermann has as much relation to the story as Disney inspirations do.
Half the 'connections' this girl made were just pointing out the obvious. Like 'the journey ends where it started', while pointing to logue town. That's obvious and even explicitly thematised by people inside of the manga again and again, when they talk about making it to the end equivalent to 'going full circle around the globe'. Yet she acts like she solved a big mystery or something.
Then you have the Disney references. Disney is huge in media. There are no more than 4 big media giants in the real world and they dictate what is being shown and what isn't. Disney has the job of coming up with the program basis for the content intended for the 'kids'. What even are Disney stories? They are new takes on old fairy tales. Fairy tales are of German origin, supposedly collected real tales from actual people and gave them a little twist by the brothers Grim.
The pool of works you can draw inspiration from lead back to the same few original creative 'minds'. So even her pointing out the relation to Disney characters is just stating the obvious.
She didn't explain anything new that is relevant to the current story. She didn't involve any of the real key elements to the story. She didn't mention how joy boy plays into anything, the ancient weapons, buggy, shanks, xebec, the moon, the lunarians, luffy's (new) wish.
She also straight up misunderstood various elements that have already been explained.
The first example she brings up to indicate that the water levels might have changed is Wano. Seriously? We already know that Wano is underwater because of the walls that were built around it. It's not underwater because of changing sea levels. Was her brain literally turned off while reading that?
Then she went on about how much sense it supposedly makes that Noah exists because it might have been used by Poseidon to save those who can not swim. But on the poneglyph it stated that Joyboy had intended to use the Noah, but it never came to that. He even apologized for it. If the Noah was never used, then it obviously can't have been the savior of anyone.
We know that all three ancient weapons are most likely to be women. Shirahoshi is already established as Poseidon, so the statement that women are ancient weapons was likely not just a joke. And then there is Zunesha who is still being punished as of now, who is said to have committed a crime during the void century. Then you have Enel, whom we have seen to discover on the moon that three races came down on Earth after they 'ran out of resources' for some reason on the moon. How did any of this play into the One Piece or the void century in her theory, where the void century is just a phase where the poles shift? If the void century was merely the time of a pole shift, then should the government not be prepared for the next one? Should they not roughly know when it occurs? Instead they act like that century lies in the past and needs to be kept there, as if that was possible if a pole shift is going to occur again and again.
