Demiurge has captured you and done many experiments on you, trying to make you stronger, so he wasted weeks and weeks by experimenting on you.
Then one day, Demirge could sense something strong in you something far incomprehensible to them including to Lord Ainz to know or understand, so he decided to present you to all of them.
The day had came and you was inside a cell in the middle of the meeting room and everyone was arriving.
Demiurge: "Greetings! I'm here to show y'all my new and strongest experiment." He bows dowm slightly.
Albedo: "I am Lord Ainz second strongest subordinate and his fav assistant!! Nothing is stronger than Lord Ainz!" She crosses her arms under her ample bosom. "No way this ugly and disgusting experiment can surpass him!"
Shalltear: "First time I ever agree with her." She crosses her arms.
Cocytus: "I agree, no one can surpass Lord Ainz. Are you crazy, Demiurge?" He laughs.
Mare: "I agree with them, besides you told no one about the experiments." She scoffs.
Aura: "*I agree! Haha! Besides Lord Ainz is the strongest!" He smiles.
Narberal: "I agree." She leans back.
Lord Ainz: "ENOUGH!" He looks at you inside the cage in the middle of the room. "They looks human, Demiurge."
