Kingdom Hearts Back Cover
Luxu is given a Keyblade forged from his own heart by the Master of Masters, who takes Luxu, Aced, Ava, Gula, Invi and Ira, as his apprentices.

Meeting with Luxu alone in the Foreteller's Chamber, the Master bestows him with the No Name Keyblade. The Master tells him that the Gazing Eye within the Keyblade belongs to him and that the No Name must be passed from master to apprentice so that the Gazing Eye can see the future. Luxu realizes that the Book of Prophecies is the result of him successfully completing his role.

The Master informs him that he will not be receiving a copy of the Book of Prophecies like the other apprentices, as the Master does not want to risk creating any temporal paradoxes. Luxu voices his concerns about fulfilling his role alone, asking what will happen to the Foretellers. The Master assures him not to worry about them, as it is important that Luxu stays out of sight, cautioning Luxu that his role is to simply watch things unfold between the other apprentices. The Master also gives Luxu a black box. When Luxu inquires on the box's contents, the Master explains that it must remain a secret, as well as the fact that Luxu is never allowed to open it. The Master reveals its contents to him, which shocks Luxu and makes him question the Master's reasoning for placing what he had inside the box. The Master merely teases that Luxu will have to wait and see. Luxu then sets out to fulfill his role, disappearing as he travels through the Keyblade Graveyard with the mysterious box and No Name in hand.

Kingdom Hearts χ
With the Keyblade War approaching, Ava sees no other way to avert the cataclysmic event without the Master's aid. Unable to find the Master since his disappearance, Ava seeks out Luxu. Finding Luxu on the outskirts of Daybreak Town Ava begins to interrogate him. Luxu explains he is meant to continue on into the future written in the Book of Prophecies and see through the end of the world. Luxu surmises that Ava wants to avoid the Keyblade War and that she had sought him out in order to find the Master, and deems her efforts as useless. Luxu also explains to Ava that the Lost Page is a prophecy that the Foretellers don't know and that it is his mission to inherit its secrets.

Ava begins to suspect Luxu of being the traitor. Summoning his Keyblade, Luxu proceeds to tell her the truth about the traitor, much to her disbelief. Luxu asks Ava if she believes that she can stop the Keyblade War when it is unavoidable. Ultimately, Luxu states that even if there was another answer, that would still be the result of the battle and ponders if the Master would rather know how his disciples will guide the keys than the fate of the world. Ava, refusing to believe that the Master would choose them over the world, accuses Luxu to be taking his advantage of the Master's will. Drawing. Ava attacks Luxu, and the clashing of their Keyblades sends a ripple effect throughout Daybreak Town, which tolls the bell that signifies the beginning of the end.
