In the most recent chapter we learned that Zunisha was in fact Joyboy's nakama in the past, as a few people had predicted.
This gives us context to what the crime could have been.
For a while now, I have theorised that the events currently unfolding connect to, 'the promised time', that was mentioned in Oden's flashback.
This is the prophecy that one day soon the borders of Fishman Island & Wano will be opened, Joyboy will arrive & the two sovereign meet.
When we go back to Joyboy's apology that Robin found in Fishman Island, it becomes apparent that Joyboy failed to keep his promise to Poseidon of taking the Fishmen to the surface.
The previous meeting of the two sovereign failed, but why?
Perhaps this was Zunisha's crime. It caused the failure of the previous meeting of the two sovereign.
This failure then in turn caused the lose of a major battle and the defeat of Joyboy.
But when and where could this have happened?
Many of you will already know that I believe that Wano's Flower Capital is the missing eye of Jaya. Not to get too far in to that theory, but this perhaps provides the explanation for a few things.
First of all, the destruction of Shandora & Zunisha crime were both 800 years ago
Shandora was destroyed for protecting the Poneglyphs, most notably, the one with the information on Poseidon's location.
The books of Shandora were all burned and it's history lost.
This would connect to why the Poneglyphs were made by the Kozuki, to prevent the message being destroyed or burned like books can be.
That would explain why the Shandorians protected the Poneglyphs with their lives.
The destruction of Shandora would provide explanation for why Wano was moved from Jaya and why it's borders have since been closed. To protect it from suffering the same fate as Shandora.
Many will know already, I believe the one responsible for this was, Onigashima aka Oars I
Zunisha's crime was potentially being responsible for causing the previous meeting of the two sovereign to fail, consequently also causing the destruction of Shandora and necessitating the separating of Wano from Jaya to protect it.
This ensured that the meeting can try again
Zunisha isn't just coming to Wano, it's returning in order to redeem itself. To ensure that the meeting of the two sovereign succeeds this time.
To conclude, let's address the interesting question. Who is it that gave Zunisha this punishment?
If this is the correct context then it would have been Joyboy, however, that doesn't sit right. Joyboy's whole thing is supposed to be about freeing people. It seems contradictory.
Perhaps then it was someone else who punished Zunisha, either for failing to help Joyboy or for attempting to help Joyboy.
There are two very conflicting possibilities.
The first is that it was Imu who punished Zunisha and it was not for failing to help Joyboy but for attempting to do so in the first place. Perhaps this is the reason why Zunisha has the same eyes as, Imu. As someone in @YoshidaShoyou's recent stream suggested.
The other possibility is that it was Nika who gave Zunisha this punishment for failing to help Joyboy and causing this failure of the meeting.
Depending on who it was who gave Zunisha the punishment the implications change quite dramatically. However, I think that no matter which way that goes, Zunisha's crime remains the same.
This crime was the reason that the previous meeting of the two sovereign failed
I almost forgot to mention this part.
What exactly could Zunisha's crime have been?
How could it have caused the meeting to fail and the subsequent fall of Shandora and moving of Wano?
This theory is a sort of sequel to another one of my theories - 'The Voice of all Things & The Music of the Universe'. - This theory will expand on some of the same ideas discussed in that theory.
If you're interested, you can read that one here -
Ever since we found out that Aokiji had left the Marines we have been wondering what his future role might be.
We later learned that he had decided to join Blackbeard. But why did he do this?
The answer may tell us what his future role will be.
When Aokiji appeared in Punk Hazard, he reassured Smoker that he was 'still himself' & that his reasonings for doing what he did was so that he could operate without the restrictions & oversight of the World Government.
