King..." Minako says. "About Sailor Pluto... We didn't know she existed. If she's the same kind of sailor soldier, why didn't we?"

"Sailor Pluto's mission and situation are entirely different from that of Princess Selenity's four guardian soldiers. She carries the blood of the god in charge of time, Cronos. She lives between time, the solitary guardian of the door of the underworld. Time is the last inviolable territory. Since ages ago, the space-time door has been off-limits, and Sailor Pluto was the one who enforced that."

Chibi Usa has taken Usagi, Mamoru, the cats, and Venus (the last remaining inner senshi to survive the Black Moon's attacks) to the future. They see a large wooden door surrounded in mist and walk forward.

"Stop!" a voice calls. "From here is the future. You cannot proceed." The woman steps forward. She carries a long staff resembling a key. A sailor suit covers her dark skin. Her dark hair blows in the wind. "I am the watcher of the space-time door, the guardian of the underworld. I am Sailor Pluto! And I will eliminate those who violate the law."

They gasp. "Sailor Pluto!?"

She holds her staff out and shouts, "Dead Scream!"

Usagi cries out in pain as wind whips sharply across her skin.

"Sailor Moon!"

Luna stares at the woman. "Sailor Pluto!" she thinks. "She actually exists here... No one has ever seen her before. The solitary guardian of time...!"

"Sailor Pluto!?" says Usagi. "No way... She's a sailor soldier!? We didn't know about her!"

"Sailor Moon," Sailor Pluto says. "No matter who you are, I cannot allow you to break the law. My mission must be to destroy you." She raises her staff again.

"Wait! Sailor Pluto!!"

She turns around and sees Chibi-Usa running quickly toward her. The girl jumps into her arms and hugs her.

"Small Lady!" says Pluto.

"You've got it wrong!" says Chibi-Usa. "I brought them here! Don't kill them! I'm sorry... I broke my promise. I had to bring others with me."

"Small Lady..." Pluto says. "Where have you been!?"

"I thought the Mystical Silver Crystal carried by the soldier of legend, Sailor Moon, would be much stronger than ours. So, I went to the past..."

"The power of the crystal is everlasting," says Pluto. "In any time, it would be the same. It doesn't matter. You broke your promise to me, stole the space-time key, and went to the past without permission."

"Please, don't get mad at me!"

"But, you're safe... Oh, Small Lady! Please don't make me worry like that." She kneels down. "Forgive my rudeness, Princess."

"Princess!?" says Usagi. "Chibi-Usa!?"

Chibi-Usa stands up. "That's right! I hadn't told you about it, but I am the princess. And since you are just ordinary people, you should all be more polite to me."

Usagi grimaces. "So you're a princess? Well, then who are your parents! And didn't they teach you any manners?"

"What!?" says Chibi-Usa. "How dare you talk to me like that!"

Pluto smiles as she watches them. "Your family has had me here since long ago. Now go. The door has opened." She motions toward the door.

Chibi-Usa holds onto Usagi's arm. "This is it, Usagi."

"Wait," says Usagi. "What about you, Sailor Pluto?"

"I cannot leave here," she says. "Visitors, please protect Small Lady."

Sailor Pluto's and Chibi Usa's First Meeting

Chibi Usa remembers her first meeting with Pluto - this translation is from Act 20 of the manga. Chibi Usa walks through the halls of the palace. "Deep in the palace... The very deepest part... At the end of the deepest hallway... I found the door. It opened to my touch. It was so light..."

Chibi-Usa comes upon a large door. She pushes on the door, and it slides open.

Sailor Pluto stands inside, holding a long staff. She kneels down. "Greetings, Small Lady."

"You know me?" Chibi-Usa asks.

"Only kindred of the Silver Millennium can come to this place. My name is Sailor Pluto. I am the guardian of this door. You and the queen are two peas in a pod. Surely, you'll become a beautiful lady too."

"Whenever you're sad, say 'Abracadabra.' That magic word will make you happy."

"Abracadabra?" says Chibi-Usa.

"Pon!" Pluto points her staff out and flowers appear from nowhere, filling the air.
