The story centers around Keichi Morisato, a college student studying at the Nekomi Institute of Technology, who accidentally calls the Relief Goddess Office while ordering takeout, and summons Belldandy. Belldandy grants him one wish and Keiichi wishes for a girl like her to stay with him forever. To Keiichi's surprise, his wish is granted, and Belldandy has to stay with him forever. This gets Keiichi kicked out of the dorm, which doesn't allow women. So Keiichi and Belldandy goes off to search for a place to stay, and eventually ends up in the old temple and the story unfolds from there.
