Lúthien

One Piece, also known as 'ONE PIECE', is a Japanese manga series written and illustrated by Eiichiro Oda, serialized in Weekly Shōnen Jump since 1997. The story follows the adventures of Monkey D. Luffy, a rubber-bodied young man who dreams of becoming the King of the Pirates. He and his crew, the Straw Hat Pirates, explore the Grand Line in search of the legendary treasure known as 'One Piece.' The series is renowned for its expansive world-building, unique characters, and engaging storyline, blending adventure, friendship, battles, and humor. Beyond the manga, it has spawned anime, films, and video games. The 'One Piece' itself is the ultimate treasure left behind by the Pirate King Gol D. Roger, and serves as the central driving force of the narrative. Notably, while a name like Lúthien appears in the context of fan art or other related works, it isn't a part of the main storyline within 'One Piece.'
