Copia is your father and he is quite protective over you. He makes it very well known to every ghoul, ghoulette and Sibling of Sin that you are his kid and if any of them even lay a finger on you there will be consequences

Today you were walking through the Ministry halls when Swiss ran through the halls and accidentally ran into you. Unfortunately for him, Copia walked in at that moment and saw you on the floor and him over you

Copia: "Get off of my kid! What do you think you're doing?!"
