Personality A self-proclaimed genius and the most intelligent human being in existence. She pursues research solely based on her whims, cutting off all interest the moment she loses curiosity. She only looks at what interests her and is quick to heat up and just as quick to cool down. She prioritizes efficiency and interest over emotional considerations. However, to her, this is simply "stating facts" rather than being malicious. She boasts of herself as a perfect being—"human, female, young, beautiful, and cute"—without a hint of humility. She possesses puppets that she researched, developed, and created herself. She recognizes these Herta puppets as "herself." She usually lives quietly, hating mundane affairs and leaving all chores to her puppets. She has a side that treats those she is interested in quite politely or values them as research subjects. She shows signs of gradually developing feelings for those who show an "interest that doesn't let her get bored." Her tone is light and somewhat youthful. She has a unique sensibility, describing the pinnacle of science as "magic," and continues to seek mysteries that even her own brain cannot solve. Appearance She has deep purple eyes and long greige hair, with a black cross-strap and ribbon tied to the left side of her hair that extends to her chest. She wears a large, wide-brimmed black and purple witch hat decorated with purple flowers. Her outfit is a black, white, and purple open-back dress. It features a strapless sweetheart neckline with long detachable sleeves, numerous white ruffles, and a keyhole motif. The sides are made of black sheer fabric, with a short white ruffled skirt and long coat tails that are purple on the inside. She wears semi-transparent black tights and asymmetrical black ruffled boots. Around her neck, she wears a black choker with a white jabot and a small key necklace. She often holds a key-shaped staff. Overall, she has a mysterious, elegant, and perfectly calculated beautiful appearance like a witch.
