One Piece Creator Eiichiro Oda Finally Reveals The Sea Of Death

Elbaf Arch One piece is currently at its peak and with the release One piece chapter 1183 of May 24, 2026 in Shueisha's Weekly Shonen Jump #26, the story has now taken us all the way to West Blue. Eiichiro Oda expands the world of One Piece with each new chapter, adding more lore and bringing more exposition to every part of the great ocean that exists on this Blue Planet.

With the latest revelation in One piece chapter 1183, Eiichiro Oda has now officially established the Sea of ​​Death in the One Piece world. This sea is none other than the fateful West Blue, which is directly connected to some of the greatest tragedies that have taken place in the world of One Piece, as well as the birth of the Light of Revolution as well as the Child of Destiny.

Why Eiichiro Oda made The West Blue in one piece Sea of ​​Death

One Piece Chapter 1183 officially revealed that West Blue is the Sea of ​​Death in the world. The West Blue is one of the four blues that exist in the world of One Piece. It is a known fact and officially stated in One piece Chapter 0, which was published on November 30, 2009 in Shueisha's Weekly Shonen Jump Issue 53, that East Blue is the weakest of the seas. The Western Blues, on the other hand, are quite strong and some of the most powerful individuals have been born here. As a result, Western Blue has also seen quite a bit of chaos over the years, and this chaos has led to many calling it the Sea of ​​Death.

• The Ohara Incident: The biggest tragedies explored by Eiichiro Oda in One Piece all took place in West Blue, starting with the Ohara Incident in the Enies Lobby arc of One Piece, specifically Chapter 393, which appeared in Shueisha's Weekly Shonen Jump #3 on December 19. Ohara was seen by the 20th Ohara Scholar. The Poneglyphs in an attempt to get closer to the truth of the Void Century and then the government called a massive Buster Call, resulting in the utter destruction of the land and the genocide of thousands. The Ohara incident was just the beginning; as the story continued, Eiichiro Oda showed us the more chaotic and bloody incidents that took place in this sea of ​​death.

“Ohara Island, home to the world's largest historical library, committed the crime of attempting to decipher the Poneglyphs, an act forbidden by the world government. As a result, a naval bombardment wiped out all scholars and residents, leaving young Nico Robin as the only survivor.” — Ohara Incident Refresher by Eiichiro Oda, One Piece Chapter 1077

• The God Valley Incident: One Piece Chapter 957, which was officially released on September 30, 2019 in Shueisha's Weekly Shonen Jump Issue #44, confirmed the God Valley Incident for the first time. As revealed in the same chapter, God Valley was an island that existed in West Blue and was completely destroyed. The Elbaf arc, specifically chapters 1160-1166, did a great job of developing the incident in God Valley and showing the entire misfortune of the island the author was exploring. The God Valley Incident ended with the deaths of thousands and the wiping out of the Davy Clan, leaving Blackbeard as his sole successor. At the end of the God Valley incident, the entire island sank to the bottom of the ocean.

You won't find any map with an island called God Valley! In fact, the God Valley itself disappeared without a trace. -Sengoku, One Piece Chapter #957

• The Esperia Incident: Finally, One Piece Chapter 1183, which officially ended on May 24, 2026, introduced us to the Esperia Incident. The Kingdom of Esperia also existed in West Blue about 70 years ago. It was known to be a land famous for instrument makers and music lovers, and that's where Brook came from. Princess Shuri, who currently serves as a Gunko in the ranks of the Holy Knights, also came from the Esperia Kingdom, as did Queen Candelle, who was incredibly famous back then. While Esperia was incredibly popular at one point, things quickly went downhill and the island was eventually completely wiped out, as confirmed by Brook on page 11 of One Piece Chapter 1183.

“A long time ago, a long time ago! She was a child and I was a young man too! It was in a land that no longer exists… Esperia! Esperia was a land of music, full of workshops for making instruments of all kinds!” — Brook explaining the destruction of Esperia, One Piece Chapter 1183

Including the newly revealed destruction of the Esperia Kingdom, West Blue has already experienced the complete obliteration of three vast lands, more than any other sea in the One Piece world. It has also seen the largest number of deaths from multiple genocides, significantly more than any island, even the Grand Line. This makes it the official Sea of ​​Death in One Piece.

Why Thriller Bark The West Blue is a symbol of the Sea of ​​Death

Interestingly, the island's pirate ship Thriller Bark also hails from West Blue, and its derelict nature suggests that this island was also destroyed long ago. Although much of Thriller Bark's history remains under wraps for now, the island is currently in the New World and remains in ruins. As time goes by, Eiichiro Oda also sheds more light on his past and how it was truly destroyed, and this only adds to the idea that West Blue is a sea of ​​death.

Nico Robin and Shanks' role as the Light of the Revolution from West Blue

While the West Blue is the Sea of ​​Death, it also gave life to some of the most important characters to ever exist in the world of One Piece, and one of them is Nico Robin, also known as the Light of the Revolution. Nico Robin is the last survivor of Ohara and is the best archaeologist in the entire world. Her goal is to find out the true history of the Void Century world and bring it to light. Nico Robin carries the hopes and dreams of all those who were killed long ago by Nero Ima and the World Government and directly challenges the World Government. As such, despite being from the Sea of ​​Death itself, Nico Robin openly defies fate, which is something that all of us fans absolutely love to see.

In addition to Nico Robin, there is also the character of Shanks. Shanks was born in God Valley 39 years ago to a mysterious red-haired woman. He and his twin, Shamrock, were separated during the God Valley incident. While Shamrock was raised as a Sky Dragon, Shanks was taken in by the Roger Pirates and then raised as their son. Shanks represents the child of destiny as confirmed by Scopper Gabban himself in One Piece Chapter 1152 which was officially released on June 23, 2025 in Weekly Shonen Jump Issue #30.

“That's understandable. You're a child of destiny. But let's not dwell on tricky topics today, Shanks! Say, do you remember the Little Garden where we met Dorry and Brogy?” — Scopper Gaban, One Piece Chapter #1152

Although Shanks is a Sky Dragon, he opposes them, thus walking a fine line between good and evil in the world of One Piece. The West Blue may have seen the most death and destruction, but they saw the birth of two very key individuals who will rebuild the world of One Piece and lead to the herald of true justice.
