The Backyardigans say Ah! My Goddess!

'The Backyardigans say Ah! My Goddess!' is the first upcoming The Backyardigans TV Series crossover to be made by Hiatt Grey.

Plot
Keiichi Morisato is a college sophomore who accidentally calls the Goddess Help Line. The goddess Belldandy materializes and tells him that her agency has received a system request from him and has been sent to grant him a single wish. Believing that a practical joke is being played on him, he wishes that she will stay with him forever, and his wish is granted.

Since he is unable to live with Belldandy in his male-only dorms, they are forced to look for alternative housing, eventually seeking shelter in an old Buddhist temple. They are allowed to stay there indefinitely after the young monk living there leaves on a pilgrimage to India upon being impressed by Belldandy's intrinsic goodness. Keiichi's life with Belldandy becomes even more hectic when her elder sister Urd and her younger sister Skuld move in as well. A series of adventures ensue as his relationship with Belldandy develops.
