Ah My Goddess

Ah My Goddess! (Aa Megami-sama), is a Japanese seinen manga series written and illustrated by Kosuke Fujishima. A spin-off of Fujishima's series You're Under Arrest, it premiered in the September 25, 1988 issue of Afternoon where it is still being serialized. As of July 2008, the individual chapters have been collected and published in 37 tankōbon volumes by Kodansha. The series centers on the relationship between college freshman Keiichi Morisato and the goddess Belldandy.

Story begins with Keiichi Morisato is a good-natured, yet hapless and girlfriend-less college freshman who is often imposed upon by his elder dorm-mates and brow-beaten into taking phone messages and doing miscellaneous 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. As such Belldandy must live with him, but as his dormitory being strictly male-only, they are both forced onto the street.
