Serena went swimming, and Reeny took her brooch. Reeny decided that Serena was too selfish to be Sailor Moon. Reeny ran through the streets with the brooch, and Serena returned to find her brooch gone and the window open.

Wiseman told Rubeus that the day had come when the rabbit had the silver crystal would be at the bridge. Reeny tried to return home with her crystal key, but failed. Rubeus appeared and was about to grab her when Mars and Venus appeared and blasted him. While Rubeus recovered, Sailor Mars ran off with Reeny. Reeny slipped away from Mars and vanished into an alley.

Reeny didn't know where to go, so she fell asleep on Darien's doorstep. She woke up in Darien's apartment. Reeny asked Darien about Sailor Moon, and he replied she had no equal. Serena started pounding on the door, and Reeny used kitty magic to jump out of the balcony with a parachute. On the street she tried to use the crystal key again, but failed.

Rubeus and his ship appeared, but so did the Scouts. Mars grabbed Reeny again. Venus, Mercury, and Jupiter tried their attacks, but they had no effect. A beam from the UFO pinned them all down, and the Scouts tried to counter the beam with Sailor Planet Power. They pulled it off, but were very weak. Tuxedo Mask appeared and scooped Reeny up, while the Scouts were pulled up into the ship.

Rubeus called out to Sailor Moon that she had 2 hours to hand over the rabbit and the silver crystal or the Scouts would die. He also showed Esmeraude the four scouts hung unconscious on crosses.

Reeny asked Darien if he was Tuxedo Mask. He replied he was, but Reeny was not surprised. She had returned the brooch to Serena, but couldn't figure out why her key wasn't working. Darien tried to find out if anything was wrong in the future, but Reeny didn't tell him. Darien got angry, and listed off all of Serena's good qualities, which left an impression on Reeny.

Serena decided that she couldn't risk Reeny, but if she brought the silver crystal Rubeus would let down his guard. Meanwhile Reeny left also. Darien remarked that they were always thinking the same thing.

Serena transformed into Sailor Moon on the street, and was surprised to find Reeny behind her. Rubeus trapped them in a force field that lifted them up into the ship. The UFO took off, while Darien, Luna, and Artemis looked on helplessly.

Rubeus and Sailor Moon started fighting, and Rubeus pinned her down on the floor with increased gravity. Reeny noticed that a crystal glowed whenever he used his power. She also noticed the Scouts and ran forward, but a force field shocked her and she let loose another energy discharge. Rubeus continued to crush Sailor Moon against the walls, while Reeny tried to remove the crystal. She shattered the crystal with one of her energy discharges. Rubeus was cut off, and Sailor Moon's "Moon Scepter Elimination" sent him crashing back.

The crosses disappeared under the scouts, but the ship was on fire. The Scouts decided the only way to get out of the UFO was to use the "Sailor Teleport". Esmeraude appeared, and Rubeus thought that she was there to save him. Esmeraude replied it was better for him to die a traitor. The Scouts teleported with Reeny, and Rubeus was left on the ship as it exploded.

Dimando, Saffir, and Esmeraude decided the best way to capture the rabbit was to attack her in her dreams. Meanwhile, Reeny had a fever. She cried out "Pu" in her dreams, and the luna ball's eyes glowed. Sailor Pluto appeared in place of the luna ball. She asked the scouts to go into Reeny's dreams, because dark forces were threatening her there. They agreed. Sailor Pluto lifted her staff and they awoke in an apparently besieged Crystal Tokyo.

The Scouts found Reeny, but she didn't remember any of them and ran off. A droid appeared and threatened her, but the Scouts protected Reeny with their attacks. Reeny ran away, and Sailor Moon followed her. Sailor Moon got ahead of Reeny and told her that the Scouts were her friends. Reeny believed her, and asked Sailor Moon to save her mother. She showed Sailor Moon her mother's palace. A building in the background toppled over and Luna ran up and told Sailor Moon that the Scouts needed help. Sailor Moon ran off telling Luna and Artemis to protect Reeny.

The Scouts decided the best way to save Reeny would be to save her mother in the dream. The droid appeared, and the ground cracked beneath them. Reeny was about to fall when Sailor Moon grabbed her, and told Reeny she'd always protect her. Sailor Moon pulled Reeny up. The droid attacked Sailor Moon but she deflected it one-handed. Energy surrounded Sailor Moon, and she sent the droid flying. She said she wouldn't forgive him for trying to hurt a small child. They saved her mother, and returned from Reeny's dream.

Reeny woke up, and asked Sailor Pluto to return her to the future. Pluto replied that the enemy had a new plan, and that the Scouts would take care of her. Reeny got upset as Pluto faded away and the luna ball returned.

Esmeraude took over after Rubeus. She thought a better way to take over the earth would be to place a crystal figurine in a place with negative energy. The figurine would absorb the energy. When they were all in place and the Black Gate opened, the Black Crystal would destroy the world.

Meanwhile, Serena started having the same dreams as Darien. She dreamed that they were getting married, but they were pulled apart and everything exploded. She woke up and picked up a photo. The glass cracked.

Serena pounded on Darien's door and mentioned the dream. Surprised, he let her in and told her they couldn't be together. He'd had the dreams so many times he thought they were a prediction of the future. Serena said she didn't care if they were a prediction, as long as they were together. Darien replied they couldn't, and pushed her out the door.

Later, Serena told him she didn't care if it wasn't a good idea for them to get married, as long as they were together. They kissed.

The Scouts and Reeny decided to go to the future. Reeny wasn't sure they could defeat the enemy, but knew she couldn't run away from her fears anymore.

Reeny lifted her key and activated it. She asked the God of Time to allow them passage through the Door of Time. The wind rose around them, and they disappeared as a beam of light descended from the clouds. Sailor Moon found herself alone. She saw a building ahead, but was stopped by an indistinct figure. She told Sailor Moon Reeny had broken a time taboo. Reeny ran in front of Sailor Moon, and cried out to Sailor Pluto to not hurt her. She said she was sorry she'd broken her promise of not bringing people with her, but she thought that the Scouts could help.

Sailor Pluto was pleased that Reeny had Mastered the Key of Time, and thought she was maturing. She also remarked that Sailor Moon had always been troublesome to her (foreshadowing of Sailor Moon S). Pluto opened the gate and let them enter the corridor of time to the gateway of Crystal Tokyo. As Pluto watched them go, Luna remarked she'd heard Queen Serenity speak of Sailor Scouts who had to remain at their post at all times. Pluto was a lonely warrior who, because of her duty, had to live out her life in the Nether Realm alone.

Sailor Pluto closed the gate.

On the Dark Moon, Dimando noticed the Scouts, and was amazed that they were trying to pass through the corridor. Wiseman appeared, and said that when they caught the rabbit and the silver crystal, the Dark Crystal would be invincible. Dimando focused on Sailor Moon, and said she was beautiful. After Wiseman left, Dimando told Esmeraude to bring Sailor Moon to him, unharmed.

This startled Saffir and Esmeraude. After Dimando left, Saffir said it was all Wiseman's doing. He thought Wiseman was manipulating Dimando, and wanted to rip off Wiseman's cloak. Esmeraude agreed, but said she'd capture the rabbit and the silver crystal. But she vowed to kill Sailor Moon.

The Scouts were fighting hard against the windy tunnel. Esmeraude appeared above them and blasted them. Tuxedo Mask and Sailor Moon lost their grip on Reeny, and they all went flying. Esmeraude ordered a droid to kill everyone but the rabbit. She realized she'd forgotten to order it not to kill Sailor Moon, but didn't care.

The Scouts found each other, worried because they couldn't find Tuxedo Mask or Reeny. Suddenly the silver crystal started glowing, and in the distance a glow answered it. They thought it was the silver crystal of the future. Meanwhile, Reeny was alone with her luna ball. The droid approached her dressed as Neo-Queen Serenity, but Reeny saw through it and yelled for luna ball. The ball clobbered the droid, and Reeny turned it into a sling shot. Her shots had no effect, but the Scouts arrived!

The droid couldn't believe they had gotten through the gateway, but Sailor Moon replied that luck was on their side. The Scouts tried their attacks, with no luck, and Mercury analyzed the droid. She said the only way to defeat it was Sailor Planet Power, but Sailor Moon pointed out they would be attacked while they powered up. Reeny told them she'd distract the droid, and staggered it with her moon beam. The droid angrily shot a blast at Reeny, but Tuxedo Mask scooped her up in time. The Scouts finished powering up and destroyed the droid.

Glad to be reunited, they went through the gateway. They stared at a very blasted Crystal Tokyo. Reeny couldn't believe it, and ran into the fog crying for her mother. The Scouts tried to find Reeny, but instead met a man who resembled Tuxedo Mask. The man welcomed them to the 30th century. Tuxedo Mask and Sailor Moon recognized his voice, the same one from their dreams! Tuxedo Mask became enraged, and charged him, but instead went right through him. The man introduced himself as King Darien, Tuxedo Mask's future self.

Sailor Moon wanted to know why he sent them bad dreams, but King Darien insisted that they go to the Crystal Palace where it was safe. Darien assured her that Reeny was at the palace and was safe.

Dimando watched them from above. He'd already noticed that Sailor Moon and Neo-Queen Serenity were the same person. Unnoticed by Dimando, Esmeraude was enraged. She realized that he was in love with Sailor Moon.

The Scouts arrived in a special room in the palace. Darien told them that, normally the Queen was the only one allowed in there. Sailor Moon was still concerned about Reeny, but Darien assured her that she was safe and tells them they had to understand the situation.

In the future, the world would undergo a frozen sleep. Neo-Queen Serenity used her power to awaken it and created a Utopia called Crystal Tokyo. Everyone on Earth had to undergo a purification by her crystal, and those who didn't want to be cleansed rebelled. Together, Darien and Serenity defeated the rebellion. Those who still refused cleansing left the Earth and were never seen since. Until the Dark Moon attack.

They'd chosen to live on a planet at the edge of the Galaxy shrouded in darkness, Dark Nemeses. For that reason they'd been undetected until recently when the planet had become visible. Meanwhile, the people had come together and formed their own society called the Dark Moon Family. When Crystal Tokyo's defenses had mysteriously failed, the Dark Moon appeared and began to attack. The only hope was when the Scouts of the future joined their powers and created a shield around the palace.

King Darien was hurt in the attack, and he couldn't move. So they were seeing a hologram of himself. During the attack, their only hope of defeating the enemy had been the silver crystal, but Neo-Queen Serenity was the only one who could use it. Then he told Sailor Moon that Neo-Queen Serenity was her future self. Sailor Moon was beyond shock at this.

When things settled down, he showed them a picture of Neo-Queen Serenity encased in a crystal. He explained that during the battle, Serenity was outside the palace when a bolt of energy hit her. The Scouts used their powers to form a crystal around her as a protective shield, but something went wrong. She fell into a deep sleep and nothing they'd tried had woken her or broken the crystal.

The floor opened, and Reeny appeared asleep. Sailor Moon and Tuxedo Mask rushed forward to see that she was all right. King Darien said "She is your daughter." Sailor Moon and Tuxedo Mask blushed a bright red. Jupiter, Mercury, and Venus couldn't believe it, but Mars was beyond accepting it.

"What day, what month, what year did this happen?", Mars blurted out. Darien continued, that Reeny had only wanted to help her mother. He'd told her stories of the strongest and most powerful of all the Sailor Scouts, Sailor Moon, as bed-time stories. She'd only known Sailor Moon as a legend, and had thought that bringing the silver crystal to the future would save Neo-Queen Serenity. Darien apologized to Sailor Moon and Tuxedo Mask about the nightmares, but explained that they needed to know their love was strong enough to survive hardships, because they were destined to face worse challenges. He asked Tuxedo Mask to protect his daughter, and Tuxedo Mask promised to do so with his life.

Suddenly Darien vanished and Dimando appeared. His Dark Moon on his forehead become a third eye, and its power transfixed Sailor Moon and left the others helpless. Sailor Moon started to float upward to him still holding Reeny, but Tuxedo Mask managed to pull his cane and throw it at Dimando. Dimando was distracted enough that Sailor Moon dropped Reeny. Tuxedo Mask caught Reeny, but Dimando grabbed Sailor Moon and vanished. Tuxedo Mask was about to take off after them, when King Darien stopped him and told him he knew where Dimando had taken Sailor Moon.
