Chibi Chibi, Sailor Moon and others in “Unfinished Business”

[voice over as the Light of Hope]: She is no longer Galaxia. Galaxia's body is now under the complete control of Chaos. From the moment she sealed Chaos within herself, it has slowly corrupted her body. She left behind one ray of hope. She cut off her Star Seed, which was still untainted, and released it into the galaxy. Eventually, it has found its way here... to you.

So, Chibi-Chibi is...?

But now, it is too late. Please, Sailor Moon, save the galaxy with that sword you hold.
