Story:
Oh My Goddess! is a story about an ordinary University student named Keiichi Morisato, who accidentally dialed the wrong number and reached the Goddess Help Line. This caused the First Class goddess Belldandy to appear out of a mirror and allow Keiichi one wish. Thinking that this was a joke, Keiichi wished "a goddess like you to be with me always." To his surprise, the wish was approved by the system, and as one thing led to another, Keiichi and Belldandy got kicked out of the dormitory as it was not co-ed causing them to move to an abandoned temple. Unfortunately, this was not the end to Keiichi's problems as Belldandy's older sister, Urd, decided to drop in on the couple and was accidentally stranded on earth. But trouble was not far behind as with Urd's absence, some problems in the system occurred and the youngest sister Skuld appeared at the temple.
