Its all a game of Davy Back Fight. The three worlds are three rounds of the game. This is the final round of the game. Nika lost the first two rounds which is why his companions were taken, but they will all meet again when he wins round three. Lily was the previous "One Piece", Nami is World 3's "One Piece". Roger thought it would be Shakky hence being born to soon. Imu thinks it's Vivi and previously thought it was Shirahoshi. You need to take One Piece to Laughtale to win the game.
