Meanwhile, her twin sister, Ruby, is determined to become an idol just like her mother. She goes through auditions to get the chance, and she tries her best to stay away from the same dark path her mother took.

Meanwhile, her brother, Aqua, continues his search for their mother’s killer and sabotages her efforts to join the idol industry.
