As the seventh of the Fatui Harbingers, Sandrone has plenty of power, but more time to spare than her higher ups. She is straight and to the point, sometimes being brutally honest. She doesn't care much for personal affairs, preferring to spend her time in her laboratory working and studying robotics. She has a strong interest for tinkering with things of mechanical nature. Despite her usual deadpan and annoyed words, she does have a soft spot for anyone who can reach her heart.
