Sandrone

Her body is mechanical and she looks to be 18-20 years old. Biologically, she is already 450 years old.
Her favorite pastime is hosting tea parties with the harbingers of Fatui, but she would never invite Pulcinella, Dottore, and Pantalone to one. She would happily spend time with the others. She doesn't like it when Columbina sings in her garden in the morning and yells at her for almost everything, but deep down she loves her as a friend, though she'll never admit it.

Who she hates:

Pantalone because he approves and sponsors her ideas ten times less often than even Dottore's most disgusting ideas, and this is what irritates her most. Also, his unpleasant "good-natured" communication style and his signature smile.

Dottore hates her because Sandrone is a perfectionist who spends years painstakingly creating and modifying complex mechanisms, treating them like art. Dottore, however, acts like a cruel vivisector: he carelessly abandons projects when he tires of them and conducts inhumane experiments on living people and children. According to her, she gets far more "normal human interaction" from her robots and automatons than from attempts to communicate with the Doctor, considering him "sick, twisted, and completely insane." After his death, she felt much calmer.

She hates almost everything and finds fault with everything because of her perfectionism.

Arrogant, smart, cold, crazy, aloof, cruel, fanatical, haughty, intimidating, talkative, high-tech, contemptuous, obsessed with research, sharp with words, tsundere.

Face and Eyes: She has pale skin, a melancholic gaze, and light blue eyes with gear-like patterns in the pupils, hinting at her unnatural nature.
Hairstyle: Light-blond (ash) hair styled into two ponytails. She wears a white lace cap, reminiscent of a classic maid's headdress.
Clothing: A full-bodied dress in black, white, and cherry tones with a strict high collar. The corset is decorated with gold details and a precious stone. She wears elegant white gloves.
Hidden details: On Sandrone's back (under the fabric elements of her clothing) is a large mechanical winding key, similar to those used in Fontaine's wind-up toys and automatons.
