Duel Priestess

A Duel Priestess or Duel Sister ( Dyueru Shisutā) is a special woman who takes part in an annual religious ritual against the Duel Priest since ancient times. This ritual involves the ressurection of the Ultimate God, and is fulfilled with a Turbo Duel (which was made with horses at that time).

Powers and Abilities
During the ritual Duel, it is said that a Duel Priestess' loss would cause the sun to hide. By that way, the Duel Priestess' win became a tradition, along with prayers wishing peace for the year and related celebrations.

If a Duel Priestess lose the ritual Duel, the Ultimate God is said to revive, and a great disaster to occur.

Story
5000 years ago, the power of the ultimate God was feared by people. Rex Goodwin told the Duel Priestess of that time to lose on purpose, in order to raise the sense of danger and unity of the citizens. The Duel Priestess did what Goodwin said and lost, which caused a disaster. A kind of eclipse occurred and people started dying.

5000 years later, Rex chose Akiza Izinski as the next Duel Priestess. After her loss to Kalin Kessler, Goodwin gave her a blank Duel Dragon card, passing the memories of the previous Duel Priestess to Aki. Aki's personality then changes.

Then, Rex and his brother, the Skeleton Knight, realize the ritual once again, using Akiza as the Duel Priestess and Sect Ijuin as the Duel Priest.
