Levia is the shortened name of Leviathan. She joins Luka when two conditions are met. One, Luka and co must have beaten her in a battle. Two, the party must have recruited Selene which requires the party to have done her side quest in Gold Port at least once. It does not matter if the quest has not been done on the current playthrough. Note that both Navy and Pirate route can recruit Levia.
