Trivia

 * Neuronist has a small torture tool based on the idea of Kidney Stones (which plagued her creator).

Quotes

 * (To Heavy Masher's Member): "There was this one time Ainz-sama was staring at my body. It was the stare of a male selecting a target for his hunt. Then he turned his face away as if he was embarrassed. It made my chest tighten and sent chills down my back."


 * (To Heavy Masher's Member): "Listen well. Because he remained, we, who were created by the Forty-One Supreme Beings, were allowed to exist. Our very existence is to serve him. Do you think we’ll show even a shred of mercy to some filthy thieves that tracked mud into the holy place where such an exalted being lives? Do you really think that?"
 * (To Heavy Masher's Member): "One of the Forty-One Supreme Beings. He ruled over the other Supreme Beings in the past, and he is very, very cool. If you look at him once, you’ll want to swear loyalty with all your heart, too. If Ainz-sama ever calls me over to his bed, I don’t mind offering my first time to him."
 * (To Heavy Masher's Member): "My creator used to suffer from a little problem called ‘kidney stones’. To pay respects to that, we’ll start with this. Since it became so small, I don’t think we’ll have much problem putting it in."
