A meteor is heading on a collision course with the Earth! But what's this, Flowers? Usagi and friends are out enjoying the day when a childhood friend of Mamoru shows up. It is his intention to become Mamoru's exclusive friend and eliminate anyone in his way.
It's Christmas vacation and time for the shuttle to launch into space. Unfortunately, an unnatural ice storm has struck the city and it's up to our heroines to find the cause. That's if they weren't trying to find Luna. Ah, love... Even Luna has caught the bug and has become the smitten kitten when she is saved by a kind astronomer. Fallen in love with a man? Poor Artemis...
The Magical Dream Vortex! Sailor Soldiers, please save the children's dreams! The wicked Badiyanu has come to capture all the children to gain enough power to absorb the earth into her Black Dream Hole. The Black Dream Hole is located in the center of Badiyanu's castle and absorbs all the dream energy from the children. The more children Badiyanu kidnaps, the larger the dream hole gets. Once it reaches a certain size it will be large enough to swallow the planet, sentencing all the people to eternal sleep in evil dream boxes! When Badiyanu finds out Mini Moon has an enormous power that will greatly assist her in her quest, she kidnaps Mini Moon along with the other children.
Will Sailor Moon and the Sailor Scouts reach Mini Moon and the Children in time? Or will Badiyanu prevail in drawing the earth into the eternal Dream vortex?
