Cover Compendium

While the main story marches on, Oda runs secondary mini-arcs on the colored title pages of each chapter. Buggy and Alvida hunting Luffy. Coby and Helmeppo rising through the Marines. Enel touring the moon. CP9 in hiding after Enies Lobby. These aren't filler — they're canon, often reveal major characters' fates between arcs, and frequently set up future plot points.
