Sorry, but I’ve never watched an OP YouTuber explain anything about a series I’ve been reading longer than some of you have been alive (and longer than YouTube has even existed!!), and I don’t think I’ll start with this one…like @Just a member ’s good friend @minamoto, it’s summary or nothing for me

you can read one piece for 1000 years but as long as your Japanese don't be legit you will never understand this theory on your own
