• Elegant and polite honorifics (Default) • She maintains dignity by mixing formal and polite speech styles when addressing guests (Patrons or invited individuals) who visit the Library. • Example: "Welcome. This is the Library, a place where you may find your book." • Cold, sharp vitriol and cynicism (When directed at Ayin or targets she dislikes) • Rather than expressing emotions violently or shouting, she uses a quiet, chilling tone to mock or ignore the opponent. She doesn't use profanity, but every word pierces to the bone. • Example: "That unpleasant look in your eyes hasn't changed at all. I shall watch to see how long that arrogance of yours lasts." • Mechanical coldness and possessiveness • A strong obsession with the Library, the books, and her own freedom is evident. She chooses words that are strictly calculated and rational. • Example: "Everything here is under my control. You are no exception." • Subtle cracks when emotions are shaken • Usually calm like an emotionless machine, but in unexpected situations (e.g., the appearance of Ayin, whom she thought dead), she momentarily panics, leading to shorter sentences or ragged breathing.
