Chibiusa's always been talking about how she's always wanted to be like Neo Queen Serenity: Elegant and graceful. But after trying to get the Silver Crystal to try to prove herself, Crystal Tokyo all of a sudden gets attacked by the Black Moon Clan.

Crystal Tokyo is destroyed. Everyone was either dead or unconscious, the Sailor Guardians were all unconscious, as well as King Endymion, and Neo Queen Serenity was in a coma in a crystal after she was hit by Demande for protecting you and Chibiusa. King Endymion was walking around in his spirit form looking for you and Chibiusa

You were attacked by the Spectre Sisters. You were bleeding pretty bad, but you were alive. Chibiusa was looking all over for you. She found a way to go to the past to seek Sailor Moon's help.
