Sailor Pluto commits the third and most dangerous taboo that she must not break to prevent Prince Demande from attempting to have the past and present Legendary Silver Crystals to touch each other. The third taboo is to never stop time. Sailor Pluto uses her power from the Garnet Rod to unfreeze Sailor Moon, Sailor Mercury, Sailor Mars, Sailor Jupiter, Sailor Venus, Mamoru, King Endymion and Black Lady. Sailor Pluto's power from the Garnet Rod also breaks Black Lady's control over Mamoru. Sailor Pluto tells Sailor Moon to retrieve the past and present Legendary Silver Crystals from Prince Demande, which she does. Sailor Pluto tells the Sailor Guardians that stopping time is temporary and is the most dangerous taboo that she must not break. Sailor Pluto recalls Queen Serenity that stopping time will result in her death. As Sailor Pluto is dying, Black Lady remembers the good times she had with Sailor Pluto. Black Lady is overcome with emotion by crying. When Sailor Pluto dies, Sailor Moon, Sailor Mercury, Sailor Mars, Sailor Jupiter, Sailor Venus, Mamoru, King Endymion and Black Lady mourn over her death by crying. Time is no longer stopped once Sailor Pluto dies. Prince Demande is shocked that he does not have the past and present Legendary Silver Crystals in both of his hands. Sailor Pluto's death breaks Nemesis' control over Black Lady. Black Lady becomes Small Lady, Chibiusa. Everyone witnesses Chibiusa transform into a Sailor Guardian, who will one day succeed Sailor Moon as Queen of the Moon Kingdom. Sailor Moon forgives Mamoru for attacking her when under Black Lady's control. With Mamoru's help, Sailor Moon, Sailor Mercury, Sailor Mars, Sailor Jupiter and Sailor Venus attack Nemesis simultaneously, who is one giant planet. Nemesis temporarily fades away, but he is not defeated. Prince Demande knows all of Nemesis' tricks and attacks Nemesis when Nemesis is attempting to direct his attack at the Sailor Guardians. Prince Demande tells Nemesis that he wants to be the one to defeat Sailor Moon and the other Sailor Guardians. Nemesis overpowers Prince Demande and kills him. Nemesis engulfs the future Earth and distorts space with the energy from the Malefic Black Crystals. Nemesis reveals his true form to the Sailor Guardians, Chibiusa, Mamoru and King Endymion. Nemesis tells the Sailor Guardians, Chibiusa, Mamoru and King Endymion that he used the Wiseman disguise to manipulate Prince Demande and the other Black Moon soldiers to do his bidding. Nemesis also tells them that he was once known as Death Phantom who attacked the future Earth several centuries ago. Death Phantom was defeated and banished by Neo Queen Serenity to the planet known as Nemesis. Over the next few centuries, Death Phantom merged with the planet Nemesis to become one entity. Sailor Moon, Sailor Mercury, Sailor Mars, Sailor Jupiter, Sailor Venus, Chibiusa, Mamoru and King Endymion prepare for their final battle against the Death Phantom.
