Sarah is first seen about halfway through the series. She is seen as the daughter of Seta, but we later find out that
she is only his adotive daughter. Sarah is very protective of her father, hating any woman who finds interest in her dad.
At first she is very mean, but she later becomes tolerable. She becomes a great friend of Kaolla, exploring hidden passages
with her all the time.
Seta is an archeologist who hires Keitaro as an assistant. He has a daughter named Sarah and was the object of Naru's
affections. (maybe still is *wink*) Seta is the reason Naru is trying to get into Tokyo U.
Aunt Haruka, as Keitaro calls her, is basically the main authority in the Hinata Inn. She works the shop and operates
the Beach House. She doesn't say too much and never shows much emotion, but you can tell she is intellegent and reliable.
Haruka is always seen with a cigerette-type thing in her mouth. She and Seta are old friends.
