>>3 Shoot, I gotta hand in my op fan certificate, I forgot the golden rule, I neglected to mention One Piece in my earlier comment ;-;
Joking aside, absolutely seconding the One Piece recommendation, I'm used to people groaning at the length when I bring it up but it really is so good and worth it. One of the things I love about one piece is how wide and varied the world is - people like to joke that every silly side character has that One Fan, most notably bc of known superfans of random side characters (personally, my fave appears 990 chapters in). Everything feels so rich and vibrant and the storylines have a Lot to Say. I feel I can't sum up the themes better than TheCentipede did above, Pne Piece really deserves the hype.
