Chibi-Usa and Diana had returned to the future. Usagi was really sad to see them go.
To make things worse, Mamoru was going to America for a big opportunity. He wasn't sure if he should go,
but Usagi said it was okay. Before he left for the plane, he gave her a ring (that can be interrupted as an engagement ring).
In space, Galaxia told Sailor Iron Mouse that there were many star seeds on the blue planet, and that Iron Mouse would find them to take over the galaxy. Then a light approached the plane that Mamoru was in, and the plane disappeared in a wash of golden light.
Ami, Mako, Minako, and Rei were all excited because the Three Lights, a popular idol group, were coming to their area. Usagi was subdued since Mamoru had left, but they dragged her along to a video shoot. There they saw Yaten and Taiki, and even Ami was excited to see them.
Usagi snuck into a restricted area, and Seiya saw her and told her she shouldn't be here. She didn't realize he was one of the Three Lights. Before he left he called her "Odango Atama", and Usagi got really mad because only Mamoru was allowed to call her that.
Later, she snuck around the trucks and saw Sailor Iron Mouse attack someone and take their star seed. She transformed and
challenged her, but Sailor Iron Mouse turned the person into a monster, a Sailor Scout monster, and left in a phone booth.
Sailor Moon tried to dodge the monster's attacks, when she heard finger snapping.
She turned and saw the Sailor Starlights. The Starlights started to attack the monster, but she told them to stop because the monster was human.
She used her "Starlight Honeymoon Therapy Kiss" attack and healed the monster. She turned around, but the Starlights were gone.
Later, Usagi wasn't sure how to explain what had happened to the Inner Scouts.
Ami, Mako, and Minako were all excited because the Three Lights were going to their school. Rei starts to pop up at their
school a lot, even if she doesn't go there. Seiya saw Usagi and called out to her, and she realized Seiya was one of the
Three Lights. Ami, Mako, Minako, and Rei wanted to know how she knew him.
The Inner Scouts join the battle soon, when they found someone's star seed being taken out.
Seiya kept talking with Usagi, although at the time Usagi didn't like him very much.
One time the Three Lights were discussing that being idols would mean that they could find "her".
Seiya kept making attempts on Usagi. He asked her if she had a boyfriend, and when she said he was across the ocean, he said he still had a chance.
Iron Mouse kept making attempts on different people, but Sailor Moon would always heal the monster. She tried to speak to the Starlights after the battles, but they usually just walked off. Through the episodes it was revealed that Seiya was Sailor Star Fighter, Yaten was Sailor Star Healer, and Taiki was Sailor Star Maker. Also, it looked like Luna and Yaten had become friends.
Galaxia was becoming impatient with Iron Mouse, who kept failing.
Sailor Uranus and Neptune showed up in one of the battles. Uranus told Sailor Moon to stay away
from the Starlights, as they were invaders from outside the solar system.
Seiya asked Usagi to meet him in a park one day, and hesitantly Usagi agreed.
Galaxia kept calling Iron Mouse, but she kept hanging up the phone. Then she saw a Three Lights poster, and said she should have realized earlier.
Iron Mouse called up Yaten, but Yaten replied that Taiki was writing lyrics and that Seiya was out.
Seiya asked Usagi about her boyfriend, and she replied that she wrote letters to him everyday, but he never responded.
Seiya thought Mamoru was playing games with Usagi, but she said it wasn't so. Seiya stared at Usagi, and thought that
she felt like the princess they were looking for. Then he snapped out of it, and took her to a disco.
Sailor Iron Mouse had done some research, and realized Seiya was probably at the disco. She went there, and saw Usagi and Seiya enter.
Usagi and Seiya started dancing, and Usagi was really nervous. Then the lights went out, and Iron Mouse appeared.
Seiya told Usagi to escape, and Usagi ran off and transformed.
Iron Mouse fired her fireballs, but Seiya jumped out of the way and transformed into Sailor Star Fighter. Iron Mouse was shocked, then Sailor Moon arrived! As Sailor Moon went through her speech, Iron Mouse began to cry. Sailor Moon asked what happened to Seiya, and Fighter said that he was all right. Iron Mouse asked Sailor Moon if she wanted to know Seiya's identity.
Fighter fired her "Star Serious Laser" at Iron Mouse, but Iron Mouse jumped into her telephone box.
Just then Iron Mouse got a phone call, and was really scared. It was Galaxia.
She said she had no use for Iron Mouse anymore. Galaxia appeared outside the phone booth. Iron Mouse begged for her life, but Galaxia took away Iron Mouse's bracelets, and Iron Mouse vanished. Sailor Moon was shocked, and Galaxia said that the galaxy belonged to her, Sailor Galaxia. Then she disappeared.
The Sailor Starlights said that Galaxia was the one that had destroyed their planet. Sailor Moon asked if they
could fight together, but Fighter called her spoiled and Healer told her to protect her own planet. Then they left.
Galaxia called forth the Anima-mates. They said they had 80% of the galaxy, and the only planets
left were the ones in this solar system. Galaxia told Sailor Aluminum Siren to get the rest of the star seeds.
Usagi was telling the Inner Scouts about Galaxia and what the Starlights had told her, and insisted she didn't think that the Starlights were bad.
Setsuna came and told her not to trust others so quickly, since there was an evil energy all over the galaxy.
In a park, Luna told Usagi she trusted people to easily. Then a girl with heart-shaped pigtails and a white umbrella appeared in front of Usagi.
The umbrella blew away, but Usagi caught it and returned it to her. The little girl smiled, and Usagi said that she was cute. Then Usagi and Luna left.
Luna looked behind and noticed the little girl was following them. Usagi walked over and asked her who she was,
but the little girl kept saying "Chibi Chibi". When Usagi looked behind at Luna for a second, then turned back, the little girl was gone.
Sailor Aluminum Siren was cleaning up Iron Mouse's desk, when Sailor Lead Crow came. They had been top rivals among the Anima-mates,
but Lead Crow had come to check up on Aluminum Siren. Then Lead Crow told her to find a target, but Aluminum Siren said she would eat first...
Usagi returned home, and fell over. She saw the little girl standing in the house.
Her mother came over and scolded her for not going out with her little sister, Chibi Chibi!
Later the Inner Scouts were observing Chibi Chibi. Ami wondered if Chibi Chibi was Reeny's younger sister,
but Setsuna popped up again and said that the Queen's only child was Reeny. She told them to be careful of Chibi Chibi.
Then Chibi Chibi vanished and they split up to find her.
Usagi found Seiya talking to Chibi Chibi. Seiya saw her and remarked that Chibi Chibi looked a lot like Usagi, enough to be her child.
Usagi blushed, and Seiya thought she was hiding something. Then Usagi said that Seiya was hiding things too, and Seiya admitted that.
Aluminum Siren had found a target, and took out his star seed. But it wasn't the real one. Sailor Moon and Sailor Pluto arrived, and then Sailor Lead Crow arrived. Sailor Moon asked who they were, and Sailor Aluminum Siren offered her her business card. Lead Crow got upset, and introduced herself as the number one Anima-mates. Sailor Pluto attacked them, but they got into a telephone box and left. Sailor Moon used her attack and healed the monster.
Later, Usagi was writing a letter to Mamoru and became depressed. Then Chibi Chibi walked in. They both slept in the same bed.
One time, Seiya and Usagi were looking up at the stars. Seiya said that every living thing had a glittering star inside their bodies,
and that the stronger the star was, the brighter the glitter. Then he told her her glittering was exceptionally bright.
When Sailor Lead Crow was trying to get the star seed from somebody at the high school, Usagi grabbed her compact and started to transform.
But Aluminum Siren walked down the hall and saw the glittering of her transformation. She thought the glitter was the real star seed.
Sailor Moon was about to heal the monster, but Siren attacked her and said she'd take her glittering star. Then Chibi Chibi arrived, and ran over to Sailor Moon's tier. The monster stood in the way, but Chibi Chibi jumped over him and touched the tier. A beam of light came out of it and went into the sky. The Inner Scouts felt something. The Starlights felt something, and thought that that was the princess. Sailor Galaxia felt something too.
Sailor Moon and Chibi Chibi were in a dream sequence, except Chibi Chibi was in a Sailor Scout outfit. Chibi Chibi floated to Sailor Moon, and they held hands. Sailor Moon wondered who Chibi Chibi was.
They returned to real time, and Sailor Moon's tier flashed and a longer stick grew out of it. Then she used her new power,
"Silver Moon Crystal Power Kiss" to heal the monster. Siren was going to attack Sailor Moon, but the Starlights came and
Siren left. The Starlights asked what had happened, and Sailor Moon didn't know.
The Three Lights were going to debut their new movie on an airplane, and all the fan club members were going.
Usagi wanted to go, and asked the Three Lights for tickets, but they didn't have any. She was really sad.
Later, Chibi Chibi gave Usagi a letter. The letter had airplane tickets, and Usagi became very happy, but then she read the letter and it was from Sailor Aluminum Siren. Siren said she had a special seat for Usagi. Usagi was shocked, and headed off for the airport in a taxi.
When she got there, she told the stewardess to cancel the flight, but the stewardess just pushed her on the plane and it took off. Her seat was right next to Seiya's. Seiya asked her about the ticket, but Usagi couldn't tell him about Siren.
Siren was releasing sleeping gas into the other cabins. Then, in Usagi's cabin, three monsters strapped the Three Lights to their seats.
Siren appeared and told her to exchange her star seed for the lives of everyone, as Usagi or Sailor Moon.
Rei, Ami, Minako, and Mako got up to the second level and fought against the stewardesses. Siren grabbed Usagi's brooch,
but it was too powerful and she dropped it. Then she got ready to blast Usagi with her bracelets, but Seiya ripped out of the
seats and transformed. Then Taiki and Yaten got free and transformed too. The Inner Scouts watched and couldn't believe it.
Fighter used her attack and Healer told them to escape, but then all of the Inner Scouts transformed, surprising the Three Lights.
Siren told the stewardesses to attack, but the Starlights subdued them and Sailor Moon finished them off.
Siren used her "Galactica Tsunami" attack, but the other Scouts blocked the attack. Siren realized she was outnumbered, and left.
Siren returned to Galaxia, but another Scout from the shadows blamed her for what happened.
Siren said she had seen the star seed, but Galaxia just took away her bracelets, killing her. Lead Crow couldn't believe it.
After the flight, the Three Lights walked off without saying anything to the Inner Scouts.
Galaxia said that she felt a strong fluttering on Earth, and told Sailor Tin Nyanko and Sailor Lead Crow to get the star seeds. Nyanko went to Siren's desk to clean it up, and Lead Crow went too. Nyanko told her to be careful, and Crow said that Siren had done her duty, and that she would defeat Nyanko in the end.
Usagi went to a Three Lights event, and Seiya was supposed to read a post card. Instead, he made up a pen name and told her a message. Taiki and Yaten got angry. Later, Usagi thanked him, and then they heard a scream. Usagi immediately rushed off, and Seiya was going to follow, but Yaten and Taiki stopped him.
Usagi transformed. Lead Crow was trying to take the star seed from a DJ, but it wasn't the real one and Crow turned him into a
monster. The monster attacked Sailor Moon, and the Inner Scouts arrived and subdued it so Sailor Moon finished it off.
Then Crow arrived, and remembered it was their fault Siren had died. Tin Nyanko watched and said she was stupid for trying
to fight, so she used her bazooka attack and aimed it at Sailor Moon. It was about to hit her when Seiya came running and took the hit.
Seiya crashed to the ground. Healer and Maker arrived and attacked Crow and Nyanko, so they got into their telephone box and escaped.
Maker carried Seiya away, and they told them that they could defend their planet, but not to get them mixed up in it. Then they walked away.
The Outer Scouts confronted the Three Lights and told them to stay away from Usagi.
They almost got into a fight, when Seiya walked up (badly hurt) and agreed not to see her again.
Seiya called up Usagi and told her to go to a concert and listen to his song. Then he hung up.
The concert was sold out, so Usagi went on a large Ferris wheel to watch it from there. Seiya wondered if she was there, then noticed a glitter of light near the Ferris wheel (Usagi's compact was reflecting light). He began to sing his song, but it was different. He sang that it was all Galaxia's doing, that she wanted to destroy all the stars by getting all the star seeds. He said that when she got all the star seeds, the galaxy would be hers, and that his planet had been destroyed by Galaxia. But that their final hope, the princess, had escaped and came to earth, and that they had followed.
As the song ended, Seiya fainted.
Lead Crow was looking for the star seed in a concert person, but it wasn't the right one and she left. Seiya was trying to get outside, but Usagi came and transformed, then tried to protect Seiya. Then the Outer Scouts came and blasted the monster, and Sailor Moon healed him.
Later, the Outer Scouts were mad at the Three Lights for letting Seiya see her, but Usagi said it was her fault.
Taiki and Yaten were carrying Seiya away, when Seiya thanked her. Usagi was going to run to Seiya, but Haruka stopped her.
Chibi Chibi was walking in the city. She started chasing a pink butterfly, then found a lot more butterflies at a lake. Chibi Chibi walked on top of the water, following the butterflies, when they created a censer and turned Chibi Chibi into a Sailor Scout.
The Three Lights began to notice that the fragrance of the princess was on Chibi Chibi.
Lead Crow found Siren's secret diary and looked in it.
Galaxia was feeling the princess, and said that no matter how many star seeds she got, she couldn't take over the
galaxy if the princess existed. Galaxia called Nyanko and asked her if she'd gotten the star seeds. Nyanko said she
had some leads, but Lead Crow came and said she knew who the owner of the star seed was.
At the school festival, Chibi Chibi was outside. She saw a butterfly, and started chasing it, then opened her bag and took out the censer. Then Taiki and Yaten came, who were after the censer. They started chasing her, but Mako came and tried to stop them. Then the other girls and Seiya arrived, and after a quick discussion the Three Lights left. Lead Crow came, and said she knew that Usagi was Sailor Moon from Siren's notebook.
Yaten and Taiki told Seiya that the fragrance of the princess was around Chibi Chibi,
and that she had the censer. Seiya saw a pink butterfly, then felt something and ran off.
Lead Crow was badly beating the Inner Scouts. The Starlights arrived, but Crow said she knew they were the Three Lights.
Then Crow pulled out a capsule that contained a black hole, and she asked Sailor Moon for her star seed. The Inner Scouts told
her not to give up, but she didn't want them to get hurt. Then Crow took out her star seed, and Sailor Moon turned back to Usagi. A blast
hit Lead Crow, and she dropped the capsule and it broke. Tin Nyanko came out as the black hole surrounded Lead Crow and killed her.
Nyanko was going to take the star seed, but Chibi Chibi came in between her and Usagi. The black hole swallowed up Usagi,
Chibi Chibi, and the star seed, and Nyanko gave up and was about to leave. Then a huge explosion came out from the black hole, destroying it.
Chibi Chibi held the censer, and a powerful light shot out of it. Usagi floated in the air, and the Princess appeared and held Usagi in her arms.
When the Princess came to the ground, the Starlights began to cry. She thanked Chibi Chibi, and said she had been watching Sailor Moon from inside the censer. She said that there had been a holy war going on throughout the galaxy called the Sailor Wars, and that the Sailor Scouts had always fought against the evil. But the strongest Sailor Scout sealed chaos, which was the source of evil in the galaxy. And the chaos reappeared.
She continued that Galaxia wanted to get the star seeds and put the galaxy in a state of chaos, but there was always hope as long as the "light of hope" existed that the legendary Sailor Scout had left. She said she had come to Earth to find that power. Healer said they should just reclaim their planet, but she said that if they didn't find the "light of hope", they couldn't seal chaos. She asked Sailor Moon to help her, but then Sailor Uranus and Neptune came and told them they were being selfish. The Starlights got angry, but the Princess just said she believed in Sailor Moon and walked away.
Galaxia noticed Lead Crow's disappearance. She said she felt the energy of someone powerful on the earth, and that she had to find it.
Tin Nyanko came and said she'd found the star seed, but didn't have it. Galaxia didn't want to hear it and told Nyanko to go.
Haruka and Michiru were in a car outside Usagi's house, because they knew the enemy was after her.
Usagi was calling Mamoru's answering machine so she could hear his voice.
The Princess asked Seiya why they were using that appearance on earth, and he said that was the best way to find a woman on earth.
Next morning, Minako and Rei came to pick Usagi up so they could go to school together. At school, Ami, Minako, and Mako gave her some defense items and a whistle. During the other classes, Minako, Ami, and Mako stuck very close to Usagi as bodyguards so they could protect her. They wouldn't leave her alone.
They said they didn't want anything to happen to her while Mamoru was away, and Usagi became very sad at the mention of his name. So Ami, Minako, and Mako went to the Crown to let her alone, and Rei said it was dangerous for them to leave her.
Usagi went out on the roof, and Tin Nyanko came out in a school uniform. She transformed into Tin Nyanko. Nyanko started attacking Usagi, and she transformed. They started fighting, when a red rose came flying and hit Nyanko. Sailor Moon thought it was Tuxedo Mask, but instead it was Seiya. He transformed into Sailor Star Fighter and used his attack, and encouraged Sailor Moon to use hers. Sailor Moon used her attack and it hit Nyanko, but she managed to get into her telephone box and escape. Half of her got fried, so she was half white and half black.
Usagi became sad because the rose had reminded her of Mamoru. Seiya became serious, and asked her if he wasn't good enough. Usagi stared at him.
