Later, a young man was knocking on Mamoru's apartment door. He seemed to have been expecting to meet Mamoru earlier and was trying to find out why he hadn't showed up. Mamoru was inside the apartment but he ignored the knocking. His apartment was filled with mirrors.  The young man left just as Usagi arrived. Usagi was annoyed that someone she didn't know was knocking on Mamoru's door. She knocked at the apartment door herself but there was no answer. Usagi was not deterred.  She said it was no problem since she had the "ultimate proof of his love". Usagi produced a key and unlocked the apartment door.
Usagi stumbled around inside Mamoru's dark apartment and wondered if there had always been so many mirrors. Finally, she found Mamoru standing in a dark room, staring in an infatuated way at full-length mirror.  Usagi saw the strange golden glint in Mamoru's eye and then a shadowy figure within the mirror. She stepped towards him and trod on a mirror lying on the floor. The noise snapped Mamoru out of his reverie. Mamoru said Usagi shouldn't have come in. Usagi tried to reason with him but Mamoru was cold and said her visit wasn't needed. He was more concerned about the broken mirror and stroked it tenderly. The broken edge cut his finger. Usagi ran to him and took his hand. She tried to kiss his cut but Mamoru pulled away. Then he suddenly appeared to return to his normal self and apologized, saying he wasn't feeling himself. Mamoru said he needed to sleep.  Usagi agreed that would be for the best. She said she had brought some food and would leave it in the kitchen. She asked Mamoru to call her when he felt better. Mamoru agreed.  As Usagi left, she looked back and saw Mamoru again standing in front of the full-length mirror.

At Rei's temple, Usagi retold the events from Mamoru's apartment to the other girls.  Chibi-Usa said it sounded like the same disease that had been discussed on the TV news. Ami said it wasn't impossible and that they should look into it. Usagi wondered if it was possible to cure this disease and Mako said that no cure was known yet. Rei thought back to the mysterious reaction of the temple mirror and the crystal monsters that replicated themselves in a mirror-fashion and wondered if there mustn't be some connection. Mako thought that sounded similar to what Sailor Saturn had said before.

"The white moon is covered by a dark shadow." Hotaru had in fact joined the gathering, escorted by Setsuna.  Hotaru repeated her prophecy about an evil wish. Chibi-Usa asked what this meant. Mako said it meant that someone was jealous of Sailor Moon and wanted to get rid of her.  Hotaru said that something would begin and something else would end. She said the world was on a path to destruction...
Hotaru explained that on the night of the shooting stars, all the mirrors had been attacked by an evil woman. She said all mirrors were now possessed with a dark power and that the girls should not look into them or they might be possessed by that power. Usagi realized that this explained Mamoru's strange behaviour and the odd vision she had seen at her bedroom window.  Setsuna said that the Prince was indeed in danger, and that Haruka and Michiru were already headed to his location. All of the girls transformed into Sailor Scout mode and raced off down the city streets.
Sailor Uranus and Sailor Neptune were outside Mamoru's apartment building fighting a group of mirror-crystal monsters. Sailor Uranus wielded her sword talisman and used the attack "Space Sword Blaster".
Sailor Neptune used her talisman also and the attack "Submarine Reflection". The mirror-crystal monsters were destroyed but they immediately began to regrow.  Sailor Pluto's "Dead Scream" attack blasted away the new crystal statue-monsters as the remaining Sailor Senshi joined up with Uranus and Neptune.  Pluto said that the outer planet Sailors would hold off the crystal demons while the inner-planet Sailors went inside to help the prince.
However, when the girls tried to take the elevator they found it was already occupied... by mirror-crystal monsters!  Jupiter used Oak Evolution to retaliate then directed the other girls to the stairs. The girls dashed upwards.
Suddenly Sailor Moon froze. "What is it?" yelled Chibi-Moon, "we've got to go help him!"
"The shadow.  I just realized where I've seen that shape before!" exclaimed Sailor Moon. "Nehelenia!"
"Impossible!" said Sailor Mars.
"Nehelenia was sealed into the new moon" protested Sailor Venus.
"But what if the seal has been broken somehow?" said Sailor Mercury.
"Mamoru!" cried Sailor Moon.

The girls rushed up the stairs and burst into Mamoru's apartment. "What is this?" they exclaimed. The darkened room was filled with mirrors. Sailor Moon stepped forward, "Mamoru!  All these mirrors..."
