Thank You Ocean

After arriving at the seaside city of Meuuniere, Van, Wendy, and Joshua planned to take the train to Zonnet Junction to rendezvous with Carmen 99. However, their plans take a detour when the railway is attacked by pirates. Vivian, a foreman with a local salvage union, asks Van to assist in stopping the pirates in their next operation to retrieve an enormous metal coffin from the ocean floor. Van agrees when he hears the reward includes express tickets to Zonnet Junction. The cunning seamen named Kaiji, the captain of the pirate submarine, destroys the crane then freezes the water just as the coffin was nearly lifted. While the union tries to break through the ice, Van summons his armor and faces the pirates underwater, though struggling to maneuver against their torpedoes serves as a disadvantage. Van is able to defeat the pirates when they resurface after the union shatters the ice.
