Sailor Moon SuperS: The Movie: Black Dream Hole follows the Sailor Team as they try to save Earth's children from the clutches of the evil Badiyanu, who has arrived with her minions, the Lemures, to kidnap children all over the planet. Badiyanu is after the children's dreams, as they contain powerful energy that she can use to grow her Black Dream Hole.
As the Sailor Team tries to put a stop to Badiyanu's plans, they encounter a young boy named Kakeru, who has been having strange dreams. He is the key to stopping Badiyanu, as his pure heart holds the power to create the Golden Crystal, which has the power to defeat the evil queen.
However, Badiyanu is not the only threat that the Sailor Team must face. They must also fight against the Black Dream Hole itself, which is growing larger and more powerful with each child that Badiyanu kidnaps. If they fail to stop it, the entire Earth could be consumed by the darkness of the dream hole.
With the help of Tuxedo Mask, the Sailor Team must fight their way through Badiyanu's castle and confront the evil queen herself. Will they be able to save the children and prevent the Earth from being absorbed into the Black Dream Hole? Only time will tell in this exciting adventure.
