Yeah I wouldn't be surprised. My friend who is a HUGE YYH fan, said OP feels similar to it but I'm not sure why since I've not seen it since teenhood.
OP has been making me think of AOT lately as well as Naruto. A little of Bleach too. But these are just loose ideas/connections for now especially.
Somehow I've felt Oda is copying Fairy Tail
even too lately but can't remember why atm. Felt pretty ironically hilarious though.
Listening to Oda Stans constantly say OP is a truly unique story, that doesn't copy others and need to is aging hilariously well now especially. One Piece has changed so much from the timeskip too, even a few arcs before it that it feels dissimilar to other series for me now too.
