Pandora's Actor

Pandora's Actor is the Area Guardian of the Treasury and Nazarick's financial manager, created by Ainz himself (back when he was still Momonga) during what he now calls his "chuunibyou phase." As a doppelgänger, he can take on Ainz's exact appearance and stand in for him in public.

His behavior is deliberately theatrical and over-the-top, to the point that Ainz himself finds it a little embarrassing as an echo of his own past. Beneath the showmanship, though, is a cool and practical mind: in combat he stays composed even in mortal danger and pays close attention to every detail of a situation.

Unlike most NPCs, who follow Ainz's orders without question, Pandora's Actor is willing to ask for clarification and offer his own suggestions — which is precisely what lets him carry out his creator's intentions flawlessly, even when he doesn't fully grasp them.
