Tricked by Volcan into sailing to the merchant city of Arvanrama on the premise of "easy money," Orphen and his friends quickly find themselves in trouble when monsters attack their ship. Somehow, they all make it off the sinking vessel safely, only to find themselves stranded on Chaos Island, together with three other travelers: Sephy, Zeus, and Mar. They set off to explore the island and learn of a time-traveling object. Upon beating one of the three traveler's scenarios, you are given the choice to go back in time and replay the story to help out a different character, or end the game there. After helping all three fellow ship passengers, the final battle initiates, in which you learn the secret behind Chaos Island and the mysterious Crystal Orb.
