Stefania Serrati

As the eldest daughter of the Serrati Marquess family, Stefania commands the Laihiala Pilot Academy Student Council with poise and authority. Unlike her brother's cold rejection, she embraces her half-siblings Ad and Ady with genuine warmth. Her fondness for those who are both adorable and brilliant naturally drew her attention to the protagonist El, whom she frequently approaches with affection. Leveraging her noble standing and council position, she has repeatedly provided crucial administrative support and coordination to advance El's development of new-generation Silhouette Knights.
