Japanese name:

サラ・マクドゥガル

Sarah is a 9-year-old American from California and Seta's adopted daughter. She initially delights in making Keitaro's life miserable, however, like most of the girls in the story, she eventually warms up to him, even if she still calls him a dork.
Sarah is left for a time in the care of the Hinata Inn residents by Seta, as he feels that travelling the world with him on expeditions would be too disruptive to her childhood. There, she develops a close friendship with Su, most likely because of their shared disdain for the general order of things.
Sarah has an uncle in California. Her mother, now deceased, formerly worked with Seta and Haruka on an archaeological dig and competed for Seta's romantic attention.
