One day, Keiichi, a student at Nekomi Institute of Technology (or NIT) was in his dorm because his sempai told him to wait for a phone call. While waiting, he got hungry, so Keiichi called out for some food. He dialed the wrong number and got the "Goddess Helpers" office instead. A young cute goddess named Belldandy appeared out of the mirror and said "Our job is to help people who are in trouble, like you. I can grant you one wish, no matter what it is..." Keiichi said "I want you to stay forever". The wish was approved. Unfortunately, Keiichi lives in a men-only dorm, so he got thrown out when his sempai returned. Keiichi's friends didn't let him in either, so he and Belldandy finally settled in an old temple...
