Tharja is most noted by her obsession with Robin, stalking both genders at all hours of the day from a distance. She keeps meticulous records of their every action down to the number of times they have tossed in bed compared to previous nights. Her deepest desire is to be of use to them and vies for their attention and possible affection as well, notably training to become "a normal girl" after they give her an anecdotal comment about her unusual behavior.
