Black Lady Proves She Was Once Chibi Usa

Sailor Moon and the other Sailor Senshi can't believe that the woman who calls herself Black Lady can truly be Chibi Usa. Black Lady cackles and says, "If you can't believe it, I'll use Luna-P to make you believe!" Black Lady bounces Luna-P off the ground. It changes into an umbrella and Black Lady catches it.
