Ah! My Goddess: Flights of Fancy (2006)

Set one year after Aa. Megami-sama!. The song may say thank heaven for little girls, but whom is college student Morisato Keiichi supposed to thank when three honest to goodness Goddesses move in and take over his life? And should he really be all that grateful? After all, according to most mythologies, relationships between mortals and immortals usually leads to mortifying complications, so we're already talking about an extremely mixed blessing. And when a fourth Goddess suddenly appears, that blessing quickly becomes a curse. Keiichi's new friends may be trying to help, but sometimes Belldandy, Skuld, Urd, and Peorth seem less concerned with Keiichi's safety than they are with establishing a pecking order and ownership rights. The delicate celestial balance that exists between human and goddess is thrown into complete and utter chaos.
