The story centers on Keiichi Morisato, initially a college student who is fond of motorcycles. One day, Keiichi accidentally calls a "goddess tech helpline", trying to order food delivery. And the beautiful goddess Belldandy appears behind him, offering him a wish. Assuming it's a joke, Keiichi wishes for Belldandy (whom he finds very attractive) to stay with him forever, and his wish is immediately granted. This is complicated when Belldandy's sisters, Urd and Skuld, move in with them, bringing them even more trouble.
