Raised by the Darlian family, Relena's true identity was the princess of Sank Kingdom. She had an older brother who had gone by the pseudonym of Zechs and had been protected in the dark by him. Due to her environment, Relena was raised to be mature beyond her years even though at times she would expressed dissatisfaction toward her own environment. She later on became the queen of Sank Kingdom and worked hard for the sake of peace, despite the fact that she had to go against the wishes of the Rommefellar Foundations as a result.
