Typically, when a manga series nears its conclusion, tragic events often unfold towards the end of the work, aimed at propelling the character development of the main protagonist.
One Piece, created by Eiichiro Oda, is no exception. As the author has announced that the series will conclude in a few years, fans are already preparing emotionally for the potential sacrifices of a significant character.

However, there are suggestions that fans of One Piece might not need to worry excessively about the fates of their beloved characters. According to @sandman, a Twitter account dedicated to discussions about Eiichiro Oda’s work, this individual shared a translated excerpt revealing an intriguing detail. It appears that Oda prefers not to illustrate scenes of character sacrifice. Instead, he enjoys depicting grand celebrations following battles.

If a main character were to perish in battle, Oda would likely create scenes of “mourning” that celebrate the victories achieved after the conflict, which he finds appealing. Moreover, Oda considers these celebratory moments as the essence of camaraderie. He desires to conclude the One Piece saga with a grand and festive atmosphere.
This revelation has led fans to ponder: “Does this mean that there will be no main character sacrifices in the upcoming chapters of One Piece?” The demise of a significant character is closely tied to Luffy or his companions, as has been hinted at for quite some time in the Marineford arc.
Moreover, historically, only a few minor characters have faced tragic ends, with no major characters having to meet such fates. Thus, it seems plausible to conclude that we may not have to witness the sacrifice of any important characters in the near future of One Piece.
Nevertheless, one cannot entirely rule out the possibility that Oda may introduce shocking decisions, especially concerning characters closely tied to Luffy. For instance, figures like Garp, who is currently in a precarious position against the Blackbeard Pirates in the manga, might face dangerous situations that could lead to significant consequences.
