Ep. 13: Panty loses powers, regains them via Brief, then defeats Corset with a summoned laser and her mother.

13

Stripped of her abilities, Panty is expelled by Garterbelt and relocates to a farm run by a woman allied with Garterbelt. This woman manipulates Panty into preventing Corset from using Brief to open Hell's Gate. Panty sleeps with Brief, regaining her virginity and powers. Stocking returns to assist in the battle against Corset and the Demon sisters. Brief inadvertently opens Hell's Gate using his penis, releasing a destructive Ghost that ravages Daten City. Corset kills Garterbelt and merges with the Ghost to attack Heaven. Panty and Stocking utilize Garterbelt's credit card to purchase numerous weapons from Heaven, constructing a massive laser to defeat Corset. They accidentally fire the weapon skyward, summoning their mother, who destroys Corset and reseals the Ghost. Garterbelt resurrects to oversee the Anarchy sisters, who are exiled from Heaven again for depleting their Heaven Coins by maxing out the card. The post-credits sequence features bizarre twists that confuse the characters and hint at future events.
