The Area Guardian in charge of the Treasury and finances of Nazarick, who was created by Ains himself. He's a Doppelgänger whose face is a simple egghead with three holes dressed in a Neo-Nazi-esque uniform. In Momonga's original design, he's the combination of everything that he though was cool, with exaggerated gestures and body language. His existence embarrasses Ains, but at the same time knows he's the NPC he can trust the most and the only one who can perform all his master's tasks without misunderstanding his intentions. He's on the same level as the Floor Guardians, and can copy the appearance and skills of anyone he has seen.
