The five Sailor Senshi stare in shock that Chibiusa has become Black Lady. Wiseman, Saphir, and Prince Demande appear on the battle field and attack the Senshi. Black Lady reveals that since the second monolith has appeared, everything and everyone are beginning to vanish. She orders Tuxedo Mask to attack Sailor Moon, which he does. Black Lady attacks Sailor Moon and summons a third Black Crystal monolith to embed into the Earth. Wiseman taunts Sailor Moon and she gets ready to fight. Prince Demande breaks free of Wiseman's control and is forced to kill Saphir. He attacks Wiseman, and reveals that the hooded form was just a skeletal puppet.
The sky darkens and the planet Nemesis lowers from the clouds, and it speaks, saying Wiseman is Nemesis. Sailor Moon tries to use her power to keep Nemesis from crushing the palace. Black Lady has Tuxedo Mask steal Sailor Moon's Silver Crystal. He breaks free from her control, but only too late as Black Lady takes the crystal from him. Meanwhile Sailor Pluto senses that the future is in danger, but cannot leave because of the three taboos she took as the guardian of time.
Diana appears and promises to watch the Space-Time Door in her place, and Sailor Pluto gladly goes to Crystal Tokyo. Back at Crystal Tokyo, Black Lady has both the Silver Crystals of the past and future in her possession. Prince Demande attacks Black Lady and steals both crystals from her. He plans to put them both together, which Sailor Pluto says, will destroy everything and everyone of both the future and the past.
