Evil creatures called Ghosts are attacking Daten City, a city located on the border of Heaven and Hell, so Heaven sends down two angels (who also happen to be sisters) to stop them. One is an incredibly promiscuous blonde who can turn underwear into guns. The other is a gothic girl with an eternal craving for sweets who can turn stockings into swords. Guided by Father Garterbelt, a black priest with an afro and a variety of sexual fetishes, and their dog Chuck, they fight ghosts in incredibly sexy, exciting, and just plain old weird ways. Basically, your average Studio Gainax anime.
