Sabina is Shaddiq's closest and most capable confidant, often accompanying and assisting him with both his tasks within Asticassia and his outside work. However, she is not afraid to correct him when warranted, especially if he is getting sidetracked with stray thoughts. Sabina also serves as the main leader of the Grassley House pilots and maintains a strong sense of discipline among them to accomplish their goals.

Despite her close involvement with Shaddiq, she sees their arrangement as a pragmatic convenience for her own ends of putting the Earth on more equal footing with Space. She believes that ideals alone are not enough to change the state of the world, and she is willing to use ruthless and even violent means to achieve her aims. She has set aside her Earthian heritage for the sake of maintaining her status and plans.

Sabina has a compassionate side towards her teammates and allies, such as protecting Nika from Norea's attack and offering her the chance to study elsewhere so long as she joined her cause.
