 * Yuri has claimed that Lupusregina can be almost as sadistic and evil as Solution.
 * She is the first NPC to truly anger and disappoint Ainz due to her lackadaisical attitude and inability to properly assess the gravity of a situation during a mission she was ordered to do because of her arrogance.
 * She claims that she serves only the Supreme Beings as a maid and thus she does not help other people in chores and prefers instead to be served.
