I think you should decrease politics in this fanfic . It's good when mc meet with other anime characters interaction between them is also good . I think mc is still a bit naive he says he doesn't want to interfere in worldly matters but with his strength it is impossible. He should be a bit more assertive in worldly matters .
This story has so many points of view that it makes it very long, but I love it because it is perfectly framed and everything has its sides that make it interesting, I would just like to see the interactions of the mc in the one piece world next... no I can imagine Luffy entering the restaurant and eating until he was fat like an elephant and then the mc gets angry and looks for Garp to pay for what Luffy ate, because in reality someone will have to pay and it is always the parents, or the grandfather in this case.
