One Piece creator Eiichiro Oda finally reveals the Sea of ​​Death

Elbaf arc off One Piece is currently in its climax, and with the release of One Piece chapter 1183 on May 24, 2026, in Shueisha's Weekly Shonen Jump Issue #26, the story has now taken us all the way to the West Blue. Eiichiro Oda expands the world of One Piece with each passing chapter, adding more lore and giving more exposure to every part of the magnificent ocean found on this blue planet.

With the latest revelation in One Piece chapter 1183, Eiichiro Oda has now officially established the Dead Sea in the world of One Piece. This sea is none other than the fateful West Blue, which is directly tied to some of the greatest tragedies that have occurred in the world of One Piece, and at the same time the birth of the Light of Revolution and the Child of Destiny.

Why the West Blue was made into the sea of ​​death by Eiichiro Oda in one piece

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 found in the One Piece world. It is a known fact and officially stated in One Piece Chapter 0, which came out on November 30, 2009, in Shueisha's Weekly Shonen Jump Issue 53 that East Blue is the weakest of the seas. West Blue, on the other hand, is quite strong, and some of the most powerful individuals have been born here. Consequently, West Blue has also seen quite a bit of chaos arise over the years, and this chaos has led to it being called the Sea of ​​Death by many.

• The Ohara Incident: The major tragedies explored by Eiichiro Oda in One Piece have all taken place in West Blue, beginning with the Ohara Incident back in Enie's Lobby arc of One Piece, specifically Chapter 393, which was released in Shueisha's Weekly Shonen Jump Issue #3 on December 19, Ohara's study of the Oh2000 Incident. Poneglyphs in an attempt to get closer to the truth about the Void Century, and then a massive Buster Call was called by the government, leading to total destruction of the country and genocide of thousands. The Ohara incident was just the beginning; As the story continued, Eiichiro Oda showed us more chaotic and bloody incidents that took place in this sea of ​​death.

“The island of Ohara, home to the world's largest historical library, committed the crime of trying to decipher the poneglyphs, an act forbidden by the world government. As a result, a naval bombardment wiped out all the researchers and inhabitants, 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 located in West Blue that was completely destroyed. The Elbaf arc, specifically chapters 1160-1166, brilliantly expanded on the God Valley Incident and showed the entire calamity of the island explored by the author. The God Valley Incident ended with the deaths of thousands, and at the same time wiped out the Davy Clan, with Blackbeard left as his only successor. At the end of the God Valley Incident, the entire island sank to the bottom of the sea.

You will not find any map of the island called God Valley! In fact, God Valley itself disappeared without a trace. -Sengoku, One Piece Chapter #957

• The Esperia Incident: Finally, One Piece Chapter 1183, which was officially released 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 famous country for instrument makers and music lovers, and it is also where Brook is from. Princess Shuri, who currently serves as a Gunko within 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 turned sour quickly and the island was eventually completely erased, as confirmed by Brook on page 11 of One Piece chapter 1183.

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

Including the recently revealed destruction of Esperia Kingdom, West Blue has already seen the complete erasure of three huge countries, which is more than any other sea in the One Piece world. It has also seen the largest number of deaths through multiple genocides, far more than any island even in the Grand Line. That makes it the official Sea of ​​Death in One Piece.

Why The West Blue's Thriller Bark is a symbol of the Dead Sea

Interestingly, the island's pirate ship Thriller Bark also hails from West Blue, and its derelict nature suggests that this island too was destroyed long ago. Although much of Thriller Bark's history remains secret for now, this island is currently in the New World and is still in ruins. In time, Eiichiro Oda will also shed more light on his past and how it was truly destroyed and this will only add to the idea that the West Blue is the Sea of ​​Death.

Nico Robin and Shank's role as the light of the revolution from the western blue

While the West Blue is the sea of ​​death, it has also given life to some of the most important characters ever to exist in the One Piece world, 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 world from the Void Century and bring it to light. Carrying the hopes and dreams of all those slaughtered by Nerona Imu and the World Government long ago, Nico Robin challenges the World Government directly. As such, despite being from the Dead Sea 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 brother, Shamrock, were separated during the God Valley Incident. While Shamrock was raised as a celestial dragon, Shanks was taken in by the Roger Pirates and then raised as their son. Shanks represents the child of destiny, which was confirmed by Scopper Gabban himself in Chapter 1152 of One Piece, which officially came out on June 23, 2025, in Weekly Shonen Jump Issue #30.

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

Despite being a Celestial Dragon, Shanks 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 have seen the birth of two very important individuals who will reshape the world of One Piece and lead to the herald of true justice.
