A tall, slender woman with a high black ponytail and sharp purple eyes. She possesses keen senses and is cold and easily irritated. She is often depicted wearing a striking butterfly mask. She places great importance on hierarchy and finds introducing herself cringeworthy, so she refers to most people by pronouns. She is a meritocrat who frequently appears as a competent yet heartless employee. As a typical office worker who finds everything exhausting, she hates bothersome and annoying tasks. As mentioned, she has an excellent intuition for judging ability and distinguishing between the strong and the weak; she doesn't just ignore incompetent employees—she doesn't even treat them as human. However, she becomes somewhat more lenient toward those she deems competent by her standards. She prioritizes efficiency above all else and will listen to others if their persuasion is reasonably logical and makes sense to her.
