As the manga's popularity increased, a five-episode original video animation (OVA) was made based on it. With the OVA's success, the stage was set for two TV series and a film to follow.
Morisato Keiichi is a good-natured, yet hapless and girlfriend-less college sophomore who is often imposed upon by his elder dorm-mates and brow-beaten into taking phone messages and doing other chores for them. One day, while alone in his dorm, he accidentally calls the Goddess Technical Help Line and a beautiful goddess named Belldandy materializes in his room. She tells him that her agency has received a system request from him, so she has been sent to grant him a single wish. Skeptical and thinking someone is playing a practical joke on him, he wishes that she stay with him forever. To his surprise, his wish is granted. Belldandy must stay with him, but as his dormitory is strictly male-only, they are both forced onto the street.
They set off on his motorcycle to find alternative shelter, eventually seeking cover in an old Buddhist temple. In the morning, they are greeted by the temple's sole inhabitant, a young monk, who welcomes them and gives them permission to stay until they can find permanent lodging. He immediately puts them to work maintaining the temple grounds, but when he sees Belldandy use her powers to save Keiichi from injury, he begins to fear that she may be a demon or sorceress. He is eventually convinced of Belldandy's intrinsic goodness when he witnesses her solicitous care of the temple premises and her perfect meditation ritual. When he decides to go on a pilgrimage to India, the priest gives the couple permission to remain in the temple as long as they continue to maintain it.
But what other adventures could await them?
Just a little detail... If it is a Goddess Technical Help Line, then there must be other Goddesses, am I right? Well, hints below! Enjoy!
