Having lost her powers, Panty is kicked out by Garterbelt and moves onto a farm with an old woman who, unbeknownst to her, is in league with Garterbelt and persuades her to stop Corset from using Brief to unlock Hell's Gate. Panty has sex with Brief, losing her virginity and restoring her powers. Stocking returns to help Panty fight Corset and the Daemon sisters. Brief accidentally unlocks Hell's Gate with his penis, unleashing a massive Ghost that begins destroying Daten City. Corset kills Garterbelt and merges with the Ghost to invade Heaven. Panty and Stocking find Garterbelt's credit card and use it to buy countless weapons from Heaven and form a massive laser with which to defeat Corset. However, they accidentally fire it backwards into the sky, though it instead summons Panty and Stocking's mother, who destroys Corset and pushes the Ghost back into Hell's Gate, which is sealed. Garterbelt returns to life to continue watching over the Anarchy sisters, who are once again kicked out of Heaven for maxing out his credit card, thus using up their Heaven Coins. Following the end credits is a string of bizarre plot twists that set up a premise for another season and baffle all the characters present.
