We learned five things in the last chapter:
1) There are 4 Poneglyphs
2) The 4 Poneglyphs together shows the location to Raftel
2) Kaidou and Big Mam each has a poneglyph
3) The Kozuki clan created the Poneglyphs
4) Oden Kozuki, the father of Momonosuke, was a member of Gol D. Roger’s crew
5) Oden Kozuki was executed by Kaidou and the Shogun of Wano.
How is all of this connected? I’ll get straight to the point like I always do.
It was said that the 4 yonkou were the ones closest to One Piece and it seems that was stated in a literal sense. WB and Shanks knows how to get to Raftel so the Red Poneglyphs are “worthless” and Kaidou and Big Mam each has one. Shanks does NOT have a red poneglyph.
Kaidou stole a red poneglyph and Big Mam was ENTRUSTED with another by Roger himself. I’m not joking.
The 4 Red Poneglyphs
Oden Kozuki was a member of the Roger Pirates so of course he knows the history of the Void Century. With the new info that it was the Kozuki who made the Poneglyphs, it is blatantly apparent that Wano fought along side the Ancient Kingdom.
As we know, the AK, which includes Wano, was defeated with Wano itself being split in two and half of it siding with the 20 Kingdoms, giving rise to the marines’ swordsmanship training and the Bald Gorosei.
Being one of the AK’s strongest allies, Wano or just the Kouzuki clan, made the poneglyphs and 4 red ones detailing how to get to Raftel and they were given to 4 ally nations: Elbaf, an unknown place, Zou and of course Wano. I think the last red poneglyph is in Elbaf.
The 4 red poneglyphs show the location to Raftel when the 4 of them are deciphered meaning, Gol D Roger used the Voice of All Things to follow its guidance leading him to Raftel, implying that the red poneglyphs are not in the WG’s hands.
Roger’s crew scattered after Raftel was discovered and one of the red poneglyphs ending up in the protection a former Roger Pirate or ally: Big Mam.
Kaidou, Wano and the Red Poneglyph
Why would the Shogun of Wano joined Kaidou and murder Oden Kozuki? Because Oden was deemed a traitor.
Wano used to be under the protection of WB(after he saved it from Kaidou) but after the death of WB, Kaidou returned. This time however, things would be different. Why? Because Oden Kozuki told the Wano Shogun some info of the Void Century and I believe they were trusted friends.
Like the other Roger pirates, Oden was awaiting Roger’s successor but when Oden told his friend the Shogun about the history, the Shogun was pissed. Not only was the pissed upset at what he heard, he was filled with greed and wanted to more. The Shogun of Wano wanted a war; a war where Wano can get its revenge on this world of lies and a sense of greed for getting ultimate power.
Oden was of course against the Shogun’s irrational behavior but there was someone invading them that shared the shogun’s ideals:
100 Beast Kaidou
Kaidou thinks the world is hollow and should perish. He wants to engulf the world in the greatest war ever and the Shogun had similar motives(also, Kaidou’s wanting to commit suicide for his failures is similar to samurai committing suicide when shamed). Things got worse when the Shogun sided with Kaidou and told the beast what he knew. Yes people…Kaidou knows some of the history too. He knows what the Shogun knows. This made Kaidou want the Red Poneglyph by any means thanks to Whitebeard himself.
Kaidou recalled that WB said that whoever finds the OP would cause the world to be engulfed in a war and with the Red Poneglyph that is a key to Raftel’s location is in his possession, he goal is one step closer.
However, Kaidou can’t do a thing with the Kozuki clan. The Shogun and Kaidou thinks the members of the Kozuki clan(Momo, Kinemon, Kajnuro and Raizou) can somehow decipher the red poneglyph. This is one for the reasons the fled Wano for Zou and also how Kaidou knew to send Jack specifically to Zou. Both Kaiodu and the Shogun want to know what the red poneglyphs says.
For a second scenario, the shogun could just be a coward and decided to join the winning side.
Big Mam, Roger and the Red Poneglyph
First of all, how does Nekomunashi know that Big Mam has a red poneglyph?
I think Big Mam was a former member or at least an ally of the Roger Pirates. Why? A few reasons…
In previous theories, I came to the conclusion that the Ancient Kingdom and the D clan is based off South America or at least, the mythical cities of South America.
Big Mam also has connections to WB who was a friend of Zou and Wano.
Nothing concrete, I this is the reason why I think Big Mam was either entrusted with or was able to get her hands a Red Poneglyph. I also think that this is the reason Germa 66 are going business with her; they want that poneglyph. It also increase the chances of Big Mam becoming an ally of Luffy since he seemingly has Kaidou AND half of Wano after his head.
-Kaidou invades Wano
-WB(who Roger told everything about Raftel), chased Kaidou away to Wano his territory.
-Big Mam gets her hands on a Ted Poneglyph
-WB dies and Kaidou returns to Wano
-Big Mam makes deals with Germa 66 over the Red Poneglyph
-The Shogun sides with Kaidou and tries to froce the Kozuki to decipher the red poneglyph
-Oden dies(with a smile? a ‘D’)? to let his son and retainers escape
-The Kozuki clan flee to Zou for assistance and shelter
-Jack arrives at Zou to retrieve Raizou
