Aura

Aura is a creation of Harold Hoerwick which was Harold's attempt to create the daughter he couldn't have with the writer he loved, Emma Wielant, who was killed in a car accident. Aura was made to be the ultimate AI in the online game of the World. Morgana, the AI Harold created to give "birth" to Aura, revolted against her programming when she realized that she would have no further purpose once Aura's development was completed. To prevent Aura from being completed, Morgana connected Aura to Tsukasa whose negative emotions towards people from her real-life problems would keep Aura from awakening. But when Tsukasa develops the will to leave the World and befriends others in the game, Aura is awakened and would find herself being actively persued by the Twilight Phase, Skeith. She would create the Twilight Bracelet for Kite to wield in battling the Twilight Phases that Morgana sent to kill anyone who threatened her authority in the world.
