While sitting alone in his dorm room one day, Keiichi Morisato accidentally calls the Goddess Technical Help Line. A beautiful woman materializes is his room, claiming her agency has received a system request. She notifies him that she may grant him one wish. Skeptical that it was prank, Keiichi wishes that she would stay with him forever. He did not expect, however, to have his wish granted. His dormitory being boys only, Keiichi and Belldandy are forced onto the streets.
While looking for shelter, they come upon an old monk who lives in a temple. He allows them to stay until they find a permanent home, and sets them to work maintaining the area.
