The protagonist is touring around a museum, admiring a particular ancient Egyptian painting & wondering why the girl in the painting looks just like her.... when suddenly, her spirit is called upon on by the past "her" & she is transported to the Egyptian era. She wakes up and finds herself in a foreign place with a totally different identity...a training priest! Apparently the past "her" has an identicalappearance to hers, & she requests for the protagonist to take her role in order to change history & save her loved ones... she has no choice but to accept. The protagonist gets to meet her not blood related "sibling", her "childhood friend", the Pharaoh, the harsh head priest, an invader of the city fulfilling a curse made long ago & the playful sibling of the Pharaoh... Of course the aim of this game is to chase after all those bishies!
