Ariyadna is an extremely powerful gifted who is convinced that she is trapped in a time loop because of the effects of some kind of catastrophe that Rigasia will cause in the future.

During Session 9 Ariyadna showed herself to Antonio Vargas, Zoé Curie and Steve to warn them of the incoming Rigasia/Kesizma War, and suggested that they leave as soon as possible. When Antonio decided to defect instead, she hunted and killed him, then brought his body to where the other two were so they would die in the same place.
