Shortly after the destruction of the Eikō Maru, the Bingo Maru was sent out to search for any survivors of the ship's mysterious disaster. Travelling south towards the Ship's last known location, it too was set on fire by an unknown source, and sank quickly, leaving only a few survivors to limp across the sea on a raft to Odo Island.
