Black Lady summons Saphir and Prince Demande to subdue the Sailor Guardians, and reveals Mamoru is under her control. Mamoru attacks Usagi, while Wiseman orders Black Lady to summon another Black Crystal. Demande, who had kept a lucid mind all along, objects to the summoning of another Black Crystal because this would destroy the 30th century Earth. Demande is forced to kill his brother who attacks him by orders of Black Lady, and seemingly defeats Wiseman as well. It is revealed that Wiseman's real identity is the planet Nemesis itself, which descends upon the palace. Black Lady manages to obtain both the past and present Legendary Silver Crystals, but Demande steals them from Black Lady just as Sailor Pluto arrives to help. Demande attempts to have both Legendary Silver Crystals touch each other, which would result in the destruction of the Earth.
