Megami-sama to Watashi

Lady Edith has a grandfather who is a mummy maniac and sponsored the ruin excavation at university and a brother who studies Ancient Egypt at the university. But she hates archaeology because it's behind the times and absurd. The one day, she took in a kitten who was nearly dying and saved her from death. Edith's life changed in a major way after that...!? She can see lotus flowers sometimes and ancient Egypt temples. Who is the goddess who calls her 'My priestess' in her dreams?
