The story follows Leonard, the young hero from the first game, as he finds himself sucked into a new and even more perilous quest. Princess Cisna, who was rescued in the first game, is still alive, but the kingdom of Balandor is plunged back into chaos as the dark force that has been lurking in the shadows begins to make its presence known.
The gameplay mechanics have changed from the original game, with the removal of the attack gauge. However, the White Knight Chronicles II disc includes a complete version of the first game, allowing players to import their saves and experience the changes for themselves.
