However Brain has declared he wishes to use the book to achieve a personal goal of his, wanting to be the virus that will alter the events set in stone.

  • In Kingdom Hearts III's secret reports 11-13, an unknown author implied to be Luxu notes that one of the new leaders was an imposter and calls them a 'virus in the program'. Brain later refers to himself with this exact term in a cut scene in Union X. This could very strongly imply that Brain is the imposter among the new leaders.
  • When Lauriam confronts Skuld about his sister. Strelitzia's disappearence, Brain points out inconsistencies in Lauriam's story as if he is suspicious of him.
