Sailor Moon S: The Movie - Hearts in Ice

As Christmas vacation begins for Usagi and her friends, a fierce snowstorm hits Tokyo, bringing with it an ancient evil: Snow Queen Kaguya, who seeks to freeze the Earth in eternal ice. A magical crystal from outer space, disguised as a comet, is crucial to her plan, but Sailor Moon must find it first and use her powers to save the Earth from permanent winter. Meanwhile, Luna's unrequited love for a human astronomer named Kakeru creates tension among friends, while Usagi prepares to harness the Legendary Silver Crystal's energy to defeat Kaguya once and for all.
