Chibiusa  ordered Usagi to give her the Ginzuishou (Imperium Silver Crysta)l. She said if she didn't give it to her she would shot her with the (toy) gun she had. The reason Chibiusa went into the past to save her mother from the Black Moon and find the Ginzuishou. She hipnotised Usagi's family with Luna P into think she was their cousin. Chibiusa and Mamoru bonded well together. They spent a lot of their time together which made Usagi mad. so, you can say Chibiusa and Chibiusa weren't exactly friends.

Hotaru didnt have much friends because they were all afraid of her healing abilities. Chibiusa didnt mind much about it, thats what Hotaru liked about her.The next series is Sailor Moon Supers and that's an excellent series for Chibiusa fans.
