One Piece: Season 1, Episode 307

1 - 307: Cannon Fire Sinks the Island! Franky's Lamentation!

Franky and Robin are throwing the last remaining marines off their commandeered convoy ship when Kokoro, in mermaid form, jumps out of the water and on board, carrying the whole group from the underground passage. A moment of happiness arises as they reunite with Robin, but does not last long. The battleships have set the whole island aflame and via loudspeaker a voice announces the destruction of the group of escapees at the main gate. With no more targets left, the fleet turns its attention toward the Bridge of Hesitation, where the Straw Hats are forced to wait for their captain's arrival.
