The manga One Piece introduces Prince Loki as the Ebaf arc begins. He is first mentioned during the “Cake Island” arc through the marriage proposal of Charlotte Lola, who is seeking to find true love, which disrupts Big Mom’s plans to unite with Elbaf.
Now, the Elbaf arc has revealed the character design of Loki along with the shocking truths about him. Loki is currently hiding in Minjig while being accused of murdering his father, King Harald, who is revered. It is rumored that Loki committed the crime due to his insatiable greed, influenced by a dark curse that has been passed down through the royal family for generations.

Not only that, the public often refers to Loki as the “Cursed Prince” of Elbaf. Even as a child, he had been considered a monster by the citizens of Minjig due to an accident that resulted in a great disaster in the village. When Harald died 14 years ago, everyone in the public was eager to catch Loki, but he had vanished into thin air. It wasn’t until Shanks returned to Elbaf that Loki was finally captured.
Since the start of the Elbaf arc, Oda has frequently mentioned that Loki is a fundamentally malevolent character with unparalleled cunning, but the reality may be entirely different.
Loki Is Hiding a Significant Truth in One Piece

In chapter 1143 of the manga One Piece, Hajrudin and Loki finally meet after many years. Hajrudin is Loki’s half-brother, but he is not considered a prince due to being born into a lower class. Although Loki and Hajrudin grew up together, they are vastly different in strength and personality. Hajrudin openly displays his disdain for his brother. Tensions rise when Loki is accused of murdering King Harald.

Throughout the past six years, Loki has known that few believe in him. He explained this after Hajrudin rejected Luffy’s offer for help and wanted to take matters into his own hands. Hajrudin stated that he would never forgive Loki for the crimes against their mother and the murder of their father.
Loki replied: “Even if you don’t believe me, the truth is that I have been deeply affected by this tragic play, and the inherent darkness of my father’s murder weighs on me. You refuse to acknowledge that, don’t you?”
This statement by Loki is quite ambiguous, as it may imply that he did not kill King Harald out of greed or malice, raising suspicions about his true motivations. However, Loki also does not fully deny the act of murdering his father, posing the question: What truly happened after Harald’s death?
One theory that could explain this mystery suggests that Harald, despite being known as a ruler of the realm and the most revered figure in Elbaf, might have been involved in a political scheme that negatively impacted the peace of the region, leading to cultural conflicts and weakening the land for future military confrontations.
Details surrounding these matters remain unclear, and the public is only aware that a significant secret looms around King Harald and the true circumstances following the events could be one of the most critical revelations regarding the entirety of Elbaf.
