On the planet Auldrant, the ancient Score is believed to chart the future, and Luke fon Fabre, an heir kidnapped as a child and sheltered ever since, has never left his family's manor. When an intruder named Tear Grants breaches his home, the ensuing fight flings both of them across the world, forcing sheltered Luke to face a reality the Score never prepared him for. This manga adapts the Tales of the Abyss role-playing game, with Guy Cecil, Jade Curtiss, and Natalia Luzu Kimlasca Lanvaldear filling out Luke's traveling party.
