Sandrone

Sandrone "The Puppet" is the seventh Fatui Harbinger in Genshin Impact.
It can be said that the diva's character is quite contradictory: behind the outward harshness lies a complex, multifaceted personality
Immersion in research. Sandrone prioritizes her experiments with automatons and the study of ancient mechanisms above all else. Because of this, she often ignores social conventions and trivialities—many things and people genuinely irritate her. She can be short-tempered and abrupt in conversation, especially if someone interferes with her work.
Perception by others. Her fellow Harbingers see her as strange and difficult to deal with. Tartaglia noted that she looked at him as if she wanted to kill him, even though he had done nothing to her. Scaramuccia directly described her character as terrible and obsessed with research.
Duality in relationships. Despite her outward coldness and irritability, Sandrone has deep connections. She is especially attached to Columbine and her constant companion, Pulonia, a modified robot she considers almost a member of family. In the presence of friends, she reveals a different side: behind the usual "irritated mask" lie genuine feelings.
The process of self-discovery. Interestingly, for a long time, Sandrone herself struggled to understand her own emotions: she struggled to understand why she felt irritated, sad, or attached. This is largely due to the fact that she was created by scientist Alain Guillotin in the image of his late sister—he endowed her with an emotional module, but the process of developing a personality proved challenging for her. After her resurrection, she reassessed many things: she realized that for too long she had lived for work and the expectations of others, and decided to value what was truly important more.
So her character isn't simply "cold and arrogant." She's a person (or, more accurately, a machine with the beginnings of humanity) who has gone through a difficult path of self-discovery and learned to balance her aspirations and attachments.
