Sailor Moon S Movie: Hearts in Ice

Kaguya, the Snow Princess, is a beautiful princess who longs to fill the Earth with her possessions. She has an orb filled with ice. Unexpectedly, however, a savior appeared who helped the Earth through his own efforts. The city is engulfed in a snowstorm. The Sailor Scouts learn that the evil queen Kaguya wants to start freezing the entire planet once again. There was only one obstacle: she had lost a fragment of a comet that was helping her carry out her plan.

All her subjects come to Kaguya, and she orders them to search for it, but they find nothing. As it turns out, the astronomer Kakeru now has the comet fragment. Luna has fallen for the astronomer. He has a girlfriend, Himeko, who is an astronaut and hopes to fly into space aboard a space shuttle. One day Kakeru falls gravely ill, as all his energy flows into the fragment. Luna wishes she could become human, but for now she remains a cat. Seizing this moment, Kaguya manages to take the fragment. She throws it into the waters of the ocean, where it turns into a crystal. After that, the Snow Queen is able to begin freezing the Earth.
