If you have exactly four cards named "Pandora's Box of Hope" and four cards named "Pandora's Box of Despair" in your deck, you may start the game with exactly two rulers you own named "Pandora, Girl of the Box" that don't share a name on their J-ruler side as starting rulers.

As the game starts, if you don't control two rulers named "Pandora, Girl of the Box", expel this card.

You pay less to play the judgment process of rulers you control named "Pandora, Girl of the Box" for each Relic addition you control.

or : Put a non-chant card with "Pandora" in its name from your hand into the field.
