The Queen of Hatred shares her story with The King of Greed and The Knight of Despair, all three being 'Magical Girls' and mentioned to be sisters. She was one of the 'heroes' who wanted to protect the world, but due to her own obsession, she became unstable and even bipolar to some degree. The Queen of Hatred has shown to be more self-aware than her sisters, as her entry mentions her ability to call the Emergency Response Department. She suffers from amnesia.
