Be careful what you wish for!
College freshman Morisato Keiichi gets more than he bargained for when he goes dialing for dinner and gets an unexpected delivery - Belldandy, a real live, honest to goodness Goddess! Belldandy grants him a wish, and Keiichi decides that what he really needs is a girlfriend just like Belldandy! And that's exactly what he gets. The mysterious 'Ultimate Force' that enforces all Wish Contracts comes into play, and Keiichi and Belldandy are now inseparable. That's when Keiichi remembers that his dorm has a strict rule: NO WOMEN ALLOWED!
Can Keiichi and Belldandy find a new place to live? Will everyone buy the story that she's a foreign student? And does Keiichi have the guts to put the moves on a babe who is LITERALLY divine?

Belldandy. Urd. Skuld. They're back -- sort of! That's right, everyone's favorite goddesses are back, and this time they're on television. Unfortunately, though, someone seems to have washed them in hot water, as they've been shrunk.

Trouble in Paradise! Belldandy's mentor, Celestin, was imprisoned for attempting to overthrow the Goddess system, but now he's back! Using a system virus, Celestin, corrupts the Goddess system and removes all of Belldandy's memories of Keiich! Will Belldandy's love for Keiichi prove to be the key to ruining Celestin's plans, or will it be the final ingredient necessary to destroy our reality?!

Morisato Keiichi is looking forward to university life. But in reality, he has no luck in anything, and he has trouble with clubs, love, etc. The truth is that he has an unlucky star above his head. One day, Keiichi is stuck watching the dorm while his senpai are away, and has a mountain of chores to do to boot. But Keiichi is a good-natured person, and is set about doing his duties. As he is about to finish his final chore, he makes a phone call to his senpai. But the words that came through the receiver are, 'Goddess Help Line.' Shortly afterwards, a beautiful goddess named Belldandy appears in front of him from the mirror of his room.

One year after goddess Belldandy emerged from Morisato Keiichi's mirror and promised to stay with him forever, a new threat to their happiness emerges, one that could end the contract between Belldandy and Keiichi.
