Rika, Ryo and Megumi were walking down the street. Ryo was looking for something for his mother's birthday.

Ryo: Will she like this?

He showed them a red-coloured-blouse.

Rika: Too shiny!

Megumi: How about a stuffed dog?

Ryo: She is allergic.

Rika: And this dress?

Ryo: Grey?

Megumi: I give up! We'll never find the right present.

A black-haired little girl came in.

Ryo: Tae! What are you doing here?

Tae: Brother Ryo! I was looking for a present for Mama. Seems you aren't....

Ryo blushed.

Ryo: My friends are helping me choose the right one.

Tae: Sure they are!

Setsuna Meiou was shopping near with Hotaru. Hotaru saw Megumi.

Hotaru: Megumi!

She ran to her.

Megumi: Hotaru!

Hotaru: Hi, Meg!

She hugged her.

Megumi: Nice to see you Hotaru... Hi, Setsuna.

Setsuna: Hi, Meg, Rika... And you are...

Ryo: I'm Ryo Gingekko.

Tae came closer.

Tae: Are you Hotaru Tomoe?

Hotaru: Yeah.

Tae: I'm in your class...

Hotaru: Tae Gingekko, right?

Tae: Yeah. What are you doing here?

Hotaru: I was shopping with Setsuna-mama.

Tae: Weren't you orphan?

Hotaru: Yes, but I live with Setsuna-mama, Michiru-mama and Haruka-papa.

Tae: Still you don't have a real mother... I have to go find a present for mine... Bye!

She ran away. Hotaru got a sad face.

Ryo: Tae! Sorry about my sister, madam.

Setsuna: Don't worry, let's go Hotaru. Bye, guys!

She left with her.

Ryo: Who is she?

Megumi: I once babysat for Hotaru. She's one of Hotaru's adopted mothers.

Ryo: I'm sorry about Tae, really.

Megumi: Don't worry.

Tae, meanwhile, was followed. A little after, she noticed it and turned.

Tae: Who are you?

She was in front of a handsome purple-haired boy of about fourteen years old. His eyes were brown and wore a black boy uniform.

Boy: Me?

Tae: Yeah...

Tae: Why are you following me?

Poseiotto: I was wondering why haven't you bought something for your mom yet.

Tae's face changed.

Tae: I don't know what to give her...

Poseiotto: Why don't you give her this ring?

He took out a diamond ring. Tae's face enlightened.

Tae: Could you please give it to me?

Poseiotto: Maybe... Your mom is the most important thing for you, isn't she?

Tae: Yes...

Poseiotto: Take it, I don't like it much...

He threw it to her. She caught it and ran home. Poseidon looked at her from the sky.

Poseidon: Fool...

Next day, Tae ran to her mom.

Tae: Happy Birthday Mom! See what I bought for you!

She gave her the ring. Her mother smiled and put it on.

Mother: Thank you, my dear. It's beautiful... but how could you afford it?

Tae: I saved all my money...

Ryo came in.

Ryo: Happy birthday, Mom...

Mother: Thank you, honey.

He gave her a photograph of himself with him, Kenji, Tae and their dead father. He had made a beautiful frame for it. Mrs. Gingekko started to cry.

Mother: Thank you, Ryo...

Tae: But Mom, Ryo’s present isn’t as expensive as the ring I gave you...

Ryo looked at his sister with wonder.

Mother: But Ryo gave me something that is really valuable for my heart...

Tae left her home confused. Poseiotto appeared.

Poseiotto: Did your Mom like the ring?

Tae: Yeah, but she liked more a picture my brother did...

Poseiotto: Something made by him?

Tae: Can you believe it? She's insane...

Poseiotto left. At noon, Tae returned home. Kenji, a black-haired and green-eyed young man was at the living room.

Kenji: Hey, Tae, you did it great this time, Mom is crying in her birthday...

Tae: Why?

Kenji: Are you asking? What a girl!

Tae ran to her Mom's room and there she was. But wasn't wearing the ring.

Tae: Mama...

Mother: Why did you do it?

Tae: What?

Mother: A boy came here saying you had stolen a ring... it was the one you gave me. I return it to him. It had been stolen of the Osa-P Jewellery yesterday. They won’t present charges, but...

Tae: I didn't...

Mother: Don't lie me, please...

Tae: Mama, I didn't...

Ryo came in. Meg and Rika were with him. Kenji made him a problem sign about Mrs. Gingekko's room. The three entered with caution.

Mother: I'll have been happy with just a card... you didn't needed to steal...

Tae saw her brother and his friends and ran away.

Ryo: Tae!

Megumi: I'll go for her...

She ran after her. Tae found Poseiotto first.

Tae: You gave me a stolen ring...

Poseiotto: Yeah...

He gave Tae a freezing look and she fainted. He took out a purple crystal. It transformed him in Poseidon. He wore a black pant and a purple commander coat. His collar was divided in two parts that were violet coloured. In his shoulders were trident symbols. His crystal hanged from his neck by a black string. One of its ends hanged at side of the crystal. His shoes were brown and had a black tiara in his head.

Poseidon: Dark energy... Come!

A black shadow appeared from Tae and transformed into a Monsterdame of one eye.

Poseidon: Mom-Cyclops!

Megumi saw him. Rika appeared in her back.

Rika: Hey, you ran pretty fast...

Megumi: An attack, Rika.

Rika: Play time!

Megumi: Andromeda's Lost Senshi Power, Make-up!

Rika: Pandora’s Friendship Power, Make-up!

Both Senshi appeared in front of Poseidon.

Megumi: I'm a Sailor Senshi who fights for the people's peace, I'm Sailor Andromeda!

Rika: I'm a Sailor Senshi who fights for world's friendship, I'm Sailor Pandora!

Both: And we will defeat you in name of the Universe!

Poseiotto: You two are the guilty ones of my sister's betrayal and my twin's punishment.

Rika: Twin?

Poseidon: I'm Amphitrite's twin brother, Commander Poseidon of the Purple Sea.

Rika: One of the Sea Children, I suppose...

Poseidon: Attack, Mom-Cyclops!

MC: Disillusion Ray!

Rika and Meg both jumped away.

Rika: Pandora’s Ribbon Surprise!

Megumi: Crystal Moon Attack!

The Monsterdame was weak.

Megumi: Andromeda Moon Power...

The attack destroyed the Monsterdame and the energy returned to Tae. Poseidon disappeared. Rika and Meg turned to see the one that had thrown the attack. Eleven shadows jumped in front of them. They where all the Sailor Senshi (Inner and Outer), a Sailor Senshi with wings (that Megumi recognised as Moon) and a masked man with a tuxedo.

Moon: At last we met...

Megumi: Serenity...

She gave Pluto a supplicant look. She couldn't do anything.

Moon: Who are you both?

Rika: We are the Lost Sailor Senshi...

Uranus: But where did you come from?

Jupiter: Indeed.

Megumi: Please, don't ask us...

Mars: Who were those enemies?

Saturn: Please, tell us!

Megumi: Don't get in this battle, I don't want to hurt you again...

Mercury: Again?

Venus: Have you hurt as before?

C-Moon: You have helped us many times...

T-Kamen: Tell as who you are...

Pluto: Leave them alone!

Neptune: Pluto!

Pluto: I trust them and I know they are doing the best.

Rika smiled at her.

Moon: But why don't you tell us who you are?

Megumi got courage.

Megumi: Because we have the mission to protect everyone in this world, including you all... Sailor Pandora...

Rika: We must leave...

Moon: Wait! I do trust you... If you ever need my help, Eternal Sailor Moon's help, just ask for it...

Meg smiled. Rika took fainted Tae in her arms and jumped away.

Mars: Usagi, you really trust them?

Moon: I have confidence in them… If they really think they can save this world, we'll better let them try.

Saturn: Setsuna-mama, you know who they are, don't you?

Pluto: You are really perceptive...

Saturn: You do know them... But don't have to tell me if you aren’t allowed.

Sailor Pandora and Sailor Andromeda entered Mrs. Gingekko's Room.

Megumi: Mrs. Gingekko, an evil boy tricked your daughter, she didn't stole anything.

They left Tae and jumped away. She woke-up.

Tae: Mama...

Mother: My dear, I'm sorry...

Next day, Meg saw Setsuna and Hotaru at the mall.

Megumi: Hi!

Tae and Mrs. Gingekko were near. When Tae saw Hotaru, she ran to her.

Tae: Hey, Hotaru!

Hotaru: Tae...

Tae: Sorry for what I said two days ago, I was a brat. I'm sorry you haven't got a mama but I believe your adopted parents are as worth...

She returned to her mom. Hotaru smiled at Setsuna.

Megumi: She has understood the lesson...

Setsuna: And made my Hotaru smile. Bye, Meg... or I should say Selene?

Hotaru didn't hear that. Setsuna winked an eye and both left.
