After Mu Yu’s victory in Wano forced the Celestial Dragons to abolish slavery, he helped Kozuki Hiyori stabilize her rule and brought Wano Country into the Pirate Code. The Code began to feel nearly complete, but Mu Yu still could not identify its final missing piece and wondered whether it involved the World Government.

• Mu Yu wondered whether the Code’s missing piece involved the pirates who had not signed or the World Government and Celestial Dragons, then decided to set the question aside.

Over three years, Mu Yu and Kuina traveled the world, reached Laugh Tale, and forced the Celestial Dragons to sign the Pirate Code, which spread across the seas but remained incomplete. On an unnamed island, Kuina revealed that she and the others had guessed Mu Yu was preparing to leave, and she faced the coming departure with reluctance.
