• Eiichiro Oda, the creator of the popular anime and manga series One Piece, has reportedly revealed the true nature of the "One Piece" treasure to the voice actor who portrays the main character, Luffy. This revelation is said to debunk a major theory about the Red Line, a significant geographical feature in the One Piece world.

• According to the article, Oda has shared the secret of the One Piece treasure with Mayumi Tanaka, the Japanese voice actress who has voiced Luffy since the anime's inception. This suggests that the true nature of the One Piece treasure may be different from what fans have speculated or theorized about over the years.

• The article suggests that Oda's revelation to Tanaka could potentially undermine the popular theory that the Red Line is actually a giant, artificial structure created by an ancient civilization. This theory has been widely discussed by fans, but Oda's disclosure to the Luffy voice actor may indicate that the true nature of the One Piece treasure and the Red Line are not what fans have assumed.
