One night, while all the Straw Hats, except for Robin who was reading a book, were sleeping in their beds, they all dream of a cloaked young man playing beautiful music from a sea horn underwater. In the morning, the crew wakes up and Robin is shocked to discover they have no memories of her or their being in a Pirate Crew. With only the memories from before joining the crew still in their heads the crew begins to splinter, Nami runs away from the ship with all the gold as she has reverted herself back into a pirate-hating thief, and Zoro causes a fight with the crew and also retreats, believing that he is once again a bounty hunter.
