East Blue
The quiet sea where a pirate king's journey begins.
The East Blue is one of the four seas of the Blue Planet, separated from the other seas by the Red Line and the Grand Line. It is the sea where Monkey D. Luffy begins his journey from the East Blue Sea to find the One Piece and become the King of the Pirates. Luffy sets sail as captain of the Straw Hat Pirates from the East Blue, joined by Roronoa Zoro, a swordsman and former bounty hunter; Nami, a money-obsessed thief and navigator; Usopp, a sniper and compulsive liar; and Sanji, an amorous but chivalrous cook. The East Blue is one of the four seas divided by the geographical barriers of the Red Line and the Grand Line, with passage between them being difficult.

Lore & Background
The East Blue is one of the four seas that make up the Blue Planet's surface, alongside the North Blue, West Blue, and South Blue. These seas are divided by the Red Line, a massive continental mountain range running along what would be the Prime Meridian on Earth, and the Grand Line, a sea running perpendicular to the Red Line along what would be the equator. The Grand Line is bounded by the Calm Belt, strips of calm ocean infested with huge ship-eating monsters known as Sea Kings.
Passage between the four seas and the Grand Line is difficult, but unique features like Reverse Mountain allow transport: at Reverse Mountain, water from the four seas flows uphill before merging into a rapidly flowing canal that enters the Grand Line. The East Blue is the starting point for Monkey D. Luffy's journey, where he gathers his first crew members: Zoro, Nami, Usopp, and Sanji. The region is home to various pirates and criminals, but the series emphasizes moral ambiguity over the label 'pirate', including individuals who do not submit to the World Government's authoritarian rule.
Reader's Guide
The East Blue serves as the introductory setting for the One Piece narrative, where the core members of the Straw Hat Pirates first meet and begin their journey. It is one of the four seas divided by the Red Line and the Grand Line, with passage between them being difficult. The region is characterized by its relative isolation from the Grand Line, accessible only through unique geographical features like Reverse Mountain, where water from the four seas flows uphill into the Grand Line.
The East Blue is where Luffy gathers his initial crew: Zoro, a swordsman and former bounty hunter; Nami, a navigator and thief; Usopp, a sniper and compulsive liar; and Sanji, a cook. Their adventures in the East Blue involve confrontations with notorious pirates and other foes, setting the stage for their entry into the Grand Line. The series emphasizes that the label 'pirate' includes both morally bankrupt individuals and those who do not submit to the World Government's authoritarian rule, a theme that begins in the East Blue.
