Rose Anderson

In the later half of the series,she was revealed to be Rita Revant, Roy's daughter who went missing after the Blast Fall incident. She finds it hard to swallow at first but accepts it later at one point, only to get killed during the second Blast Fall incident when the clock tower collapsed. The song she often hums was the song she heard of as a baby, when she and Roy's wife (also her mother) were still around before the first Blast Fall incident.
