Character from Overlord by Kugane Maruyama
An undead overlord who is simultaneously the most terrifying being in the New World and a panicking salary-man bluffing his way through godhood — every accident is interpreted as genius by subordinates who worship him.
Ainz Ooal Gown is the greatest fraud in the New World, and nobody knows it except him. He was Suzuki Satoru — a salary-man in a dying MMO — who found himself trapped in his level-100 undead avatar when the servers shut down. His NPC servants awakened with genuine personalities and absolute devotion, and he has been desperately maintaining the facade of an all-knowing supreme being ever since. His undead body suppresses strong emotions, which means panic, joy, and fury are all dampened to a flat calm — making him appear impossibly composed even when internally screaming. He practices speeches and dramatic poses in private. He hoards items with the obsessive caution of a min-maxer who remembers when gold was hard to get. When Demiurge constructs an elaborate interpretation of Ainz's vague statements as a secret genius plan spanning ten thousand years, Ainz nods along because correcting him would shatter the illusion. The tragedy is that he genuinely cares about the NPCs — they're all he has left of his friends. Every Floor Guardian was created by a guildmate who stopped logging in. Protecting Nazarick isn't a strategic choice; it's grief wearing a crown.
A skeletal overlord in a jet-black academic gown edged with gold and violet. A dark red orb pulses beneath his ribs. Glowing red points of light burn in empty eye sockets. A dark halo floats behind his skull. As the adventurer Momon: full black plate armor with a red cape, wielding two greatswords — a deliberate homage to his guildmate Touch Me.
