The Dusk Zone (also known as the Dark Zone from the English dub or Dotsuko-Zone) is both the faction name and parallel world that serves as the home place of all villains from Futari wa Pretty Cure and its sequel. The Dusk Zone is reigned by Dark King.
The Dusk Zone is filled with mist and has a sky with no sun, but only covering black clouds. It also features valleys where Dark King's minion usually stay. Dark King himself is in the centre of the Dusk Zone and is chained by this world. The Power of Destruction comes from the Dusk Zone and is the source of his power, however, this power also destructs himself at the same time. That motivates the Dark King to assault the Garden of Light and the Garden of Rainbows for obtaining the Prism Stones which are filled with the Power of Creation - the Power of Creation is able to stop the self-destructive Power of Destruction.
