One Piece, Eiichiro Oda's long-running pirate saga, has aired since 1999 and is famous for emotional story arcs where crewmates part ways or allies fall. Its sweeping orchestral score, heard in scenes like farewells and flashbacks, became a staple of fan edits across YouTube and TikTok, where creators reuse sad motifs to score their own tributes. This clip captures that mournful sound associated with the series, which is why it keeps appearing in sad compilations, character memorials and nostalgic retrospectives made by the anime's huge global fandom.
