Panty and Stocking have collected enough Heaven Coins to be allowed back into Heaven. However, only Stocking is taken back while Panty is forced to repeat her duties on Earth and forbidden to have sex as punishment for her immoral behavior. To cheer her up, Brief invites her to a party where he is to be engaged to the mayor's daughter (Scanty in disguise) and instead announces his intention to marry Panty. Scanty and Kneesocks attack Panty, who begins losing her angelic powers and escapes with Brief. Panty decides to have sex with Brief, but finds herself unable to do so as she has regained her virginity. Corset and the Demon sisters appear and kidnap Brief, the blood kin of Hell's Monkey whose penis is the key to Hell's Gate, leaving Panty powerless to save him. (thetvdb.com)
