Ah! My Goddess: Itsumo Futari de

Alone in his dorm room one Saturday night (a frequent occurrence, to be honest), young Keiichi Morisato accidentally dials a wrong number that will literally change his life. You see, he inadvertently reaches the Goddess Technical Help Line, and a goddess is dispatched to grant him one wish.
