“You can’t defeat me Sailor Moon..!”

Black Lady then uses her Umbrella to hit Sailor Moon and she gets a memory of herself when she was Chibi usa and hanging out with Usagi aka Sailor Moon.

“Moth-“

Black Lady was about to say mother until she shook her head which made the memory disappear from her head and Black Lady walks towards Sailor Moon.

“You won’t win..”
