Domingo Garcia is Charles Karino's superior officer within the Levamme Imperial military. Garcia harbors deep-seated racism against individuals of mixed heritage, frequently targeting Charles with derogatory insults like "dirty rat" due to his Amatsukami ancestry. This behavior mirrors widespread Levamme societal prejudices against mixed blood. During a covert escort mission, Garcia explicitly forbids Charles from interacting with the royal protegée, Fana del Moral.
