Luffy 2 Years
The real message lies in luffy s tattoo.
Luffy 2 years. 2 years of training for strawhats. Set two years after the events of the marineford arc in which luffy reunites with his crew this arc also marks the beginning of. It means 3 days 2 years.
The return to sabaody arc sometimes known as straw hats return or straw hats reunion arc is the twenty fourth story arc in the series and the first in the fish man island saga of the one piece series continuing on from the post war arc and the summit war saga. Rayleigh was basically training luffy to be pirate king teaching him to master all the forms of haki and from what we ve seen the difference between luffy before and after the time skip is much more severe than for any other straw hat. If you took luffy s beasts and put them on any of the other islands.
Oda the mangaka then went on a 4 week break which allowed a time skip in the manga. Before the straw hats split they had just arrived at saobody archipelago in order to coat their ship so they could make the trip to the underwater fishman island. Clip from episode 521 of one piece.
Luffy and his straw hat pirates eventually took a two year break in the series going their separate ways for a while. The crew took this to mean not 3 days 3d but 2 years 2y until they would all meet up again on sabody. It reads 3d2y with 3 and d crossed out.
Spoiler below if you want.
