004 Visit to the Submarine Temple

Thanks to the agreement struck between Athena and Poseidon, teams composed of Saints of various ranks make rounds in the Submarine Temple to aid the god of the Seas in rebuilding his Sanctuary and army. Finally, it's time for Kanon's team to go on rounds. Of course, the younger of the twins is not at all happy, and neither is a certain Marina who would have preferred them to stay at home.
