Origin
Heaven
Peorth (ペイオース Peiōsu) is the Fourth Goddess to appear to Keiichi Morisato, and a major supporting character in the series. She first appears when Keiichi accidentally contacts Heaven for the second time, after which she offers him a second wish, thereby resulting in a double contract alongside Belldandy.

Ah! My Goddess/Oh! My Goddess
In a world where humans can have their wish granted via the Goddess Help Hotline, a human, Keiichi Morisato, summons the Goddess Belldandy by accident and jokes that she should stay with him forever. Unfortunately for him, his "wish" is granted. Suddenly, Keiichi is now living with this gorgeous woman all alone, causing him to be kicked out of the all-male dormitory he was staying in. But soon, after they find lodging in a Buddhist temple, Keiichi and Belldandy's relationship begins to blossom. Although they are both awkward and rather uncomfortable with one another at first, what awaits these two strangers could turn out to be an unexpected romance.
