Ah! I Shall Grant Your Wish!
Keiichi accidentally makes another call to the Goddess help line, and summons the goddess Peorth, who makes her debut in this episode. But since Keiichi already got what he wished for with Belldandy, he doesn't ask for anything else, but Peorth is intent on having Keiichi wish for something significant, and will stay there until he does.

Oh! My Goddess: Flights of Fancy
The song may say "thank heaven for little girls", but who is college student Keiichi Morisato supposed to thank when three honest to goodness Goddesses move in and take over his life?
