An ogre in the form of a handsome young man strives to destroy all his kin to earn his humanity. But for every ogre that falls, a grasping human is all too willing to join their heinous ranks...

When college student Keiichi Morisato accidentally dials the Goddess Technical Helpline, he's delivered the living, breathing, literal goddess Belldandy... and one wish. When he jokingly asks her to stay with him forever, he gets his wish, and one hilarious headache after another as Keiichi and his Goddess-out-of-water adjust to the inevitable clash of the Spiritual Plane and the Material World!

It'll be one, two, three strikes you're out for the N.I.T. Softball Club if Keiichi can't help his sister win against their campus rivals - but with the goddesses stepping up to bat, it's not going to be the old ball game! Then, it's an unrelaxing hot springs vacation when Mara returns to challenge Urd to the most feared battle imaginable: karaoke!

If three goddesses are good, surely four must be better? Not for Keiichi, whose strange power to attract divine trouble has just dialed "P" for Peorth - Belldandy's rival in the helping-humans-out-by-phone biz. But Peorth wonders why Belldandy's still hanging around Keiichi if she's really fulfilled his wishes, and is determined to provide him better "service" - no matter how fast he tries to run!

When the goddesses Belldandy, Skuld, and Urd win a free trip to a hot springs resort, it turns out they're not the only deities off on vacation. Demon First Class Mara is checked into the same rustic retreat! The old enemies call a truce, but the malicious Mara is once again up to no good...

Maybe you think Peorth couldn't cause any more trouble - well, think again! Determined to provide Keiichi "better service" than Belldandy, she's dragging him out on a date... having studied human mating customs through shojo manga! But what is the secret slight that truly drives Peorth's efforts against her rival?

Can there be too much of a good thing? For Keiichi Morisato, who lives with three sister goddesses - actual, literal goddesses - the good-thing limits are tested on a daily basis. When Keiichi accidentally contacts Peorth, an old friend and rival goddess of his girlfriend Belldandy, Peorth shows up with the assignment to make Keiichi happy... whether he likes it or not!

Learning to ride a bicycle is a little like encountering first love - a lot of panicked flailing and falling down! Skuld, who's suddenly doing both of those things at once, can't understand why her dear sister Belldandy, who's always there to help, wants her to work this out on her own. But of course, Belldandy knows a wisdom Skuld needs to learn...

Skuld, the youngest of the three goddesses living with college student Keiichi, may be a whiz at inventions, but her immaturity usually gets the better of her. Can she learn the simple joy of riding a bicycle and deal with her first crush on a boy?

Get a job! That's what you hope a college education can do for you - but when Keiichi applies to put his knowledge to work in a custom-bike shop, he finds it's not going to be as easy to graduate college as he thought! And it could be that no one's leaving Nekomi Tech ever again, when it falls under the mind-bending influence of two of the most sinister forces known to man: Mara's magic and Sayoko's ego!
