Having no magic abilities on earth, she feels like she is going back to normal life until a girl she meets in the lavatory gets strangled by an invisible person and her best friend, Susan, comes up with the theory of Black Time. Before she could learn more, even her best friend gets attacked and everyone had seemed to forgotten that Susan ever existed. She grieves for a few days until she has to visit her maternal aunt and uncle's anniversary. Her grandfather explains Black Time too her, but he too dies.
