Carol and Memphis

Crest of the Royal Family (王家の紋章 Ōke no Monshō, lit. Crest of the Royal Family), is a shōjo manga by Chieko Hosokawa. It has run in the monthly magazine Princess since 1976, and it got the 1991 Shogakukan Manga Award for shōjo. As of June 2016, there were 61 collected volumes of the manga.

The main character is Carol Reed, an American teenager from a wealthy family with an interest in Egyptology, studying in Cairo. When her mentor discovers the tomb of a young pharaoh, a curse is put on the excavation team and Carol. The curse sends her back in time to ancient Egypt, where she becomes embroiled in the affairs of Egypt and other ancient countries such as Assyria and Babylonia.

Carol meets Memphis, a handsome young pharaoh whose tomb she excavated in modern times. Despite his headstrong, initially violent nature, they fall deeply in love. This angers Memphis' half-sister, the priestess Isis, who has longed to marry him. Carol, due to her exotic looks and curious ability to tell the future, becomes a major player in ancient history...
