## One Piece Chapter 637, pages 1-3: The Ancient Ark - Chapter: 637 - Pages: 1-3 - Characters: Monkey D. Luffy ### Summary Page 1: A volume title page shows Luffy under the One Piece logo with the caption "Volume 66 To Zero." This is a volume divider image and does not advance the current chapter's plot. Page 2: The contents page for the volume lists the chapters in Volume 66, "To Zero." It includes chapter 637, "The Ancient Ark," followed by chapters 638 through 646. This page is useful for metadata and chapter title confirmation, but it is not story action. Page 3: The chapter title page reads "The Ancient Ark" and continues the cover story: "From Shipdecks Around The World Vol. 21: Drum Island - The Isshi 100 Medical Centre." A woman stands before Drum Island's castle while people cheer, showing the medical center and the kingdom's peaceful development after earlier events. It is related world material, not part of the Fishman Island battle.
