Disclaimer: I don't Sailor Moon or any of the characters therein. Celestite and Celestine are characters I have created specifically for this fic. Enjoy Minna-San.
Celestine and Celestite are citizens of The Moon Kingdom, children of a family of nobles of the Kingdom. Secretly, Celestite watched Princess Serenity from afar, being madly in love with her while his sister, Celestine snuck to Earth to furtively observe Princess Serenity's secret terrestrial lover, whom she loved intensely. They both had plans to ask them out for the Silver Millennium Ball. The day before the Ball, Serenity snuck to Earth, as the two siblings were about to ask their quarries to the Ball so that she could secretly invite Endymion. He eagerly accepted his love's invite and Celestine watched angrily at Serenity's interference.
She went back up to the moon, appearing before her brother. "We're too late, Celestite! The Princess has snuck to Earth and got to Endymion before I could. Why didn't you intercept her?" Celestine spoke angrily. "I'm sorry Celestine. Her senshi were keeping too protective of an eye on her. Then she ditched them somehow and disappeared." He replied. "I see. Then we'll have to get them at the ball and try and separate them." She said. With that, the two went their own ways to get some rest like everyone else in the kingdom in preparation for the coming ball. Everyone slept peacefully and finally the day had arrived. The palace was bustling with people running about to ready the palace for the ball while the rooms of the planetary princesses were filled with servants readying them for the ball.
On Earth, Endymion was getting ready in his finest tuxedo and mask to hide who he was. The time of the ball drew closer and Endymion walked to the transporter room in his palace to go to the Moon. He stepped in and was transported to the moon kingdom's entrance, where he walked into the palace, going to the Ballroom, and upon walking into the ballroom, was greeted by all the princesses and Queen Serenity. None of them recognized him with his mask covering his face and all but the outers looked at him with love struck awe. He just smiled charmingly after bowing to them and received a curtsy from each one.
To the dismay of the other princesses, he walked up to Princess Serenity and bowed before her, while taking her hand in his own, kissing it softly. She smiled softly as he did while curtsying to him, he stuck his arm out for her to take, and she put her hand in the crook of his arm, placing her other hand on the side of it. Endymion then led Serenity out to the dance floor and all eyes fell upon the two, including two pairs of envious ones, which belonged to Celestine and Celestite. They watched as the two members of royalty danced happily amongst the other couples on the dance floor, scheming up a way to get the one they loved.
They finally moved onto the dance floor and pretended to dance with one another so they could get close enough to their royal prey. When they were close enough, Celestine pretended to bump Serenity, which caused her to fall to the floor and as Endymion glared at them slightly and was about to help her up, Celestine grabbed him and forced him to dance with her as Celestite did the same to Serenity. They tried to get free of their stalkers, but the two wouldn't release their hold on them.
Serenity's court and protectors saw their princess and her dance partner's plight from where they were with their own dance partners. Each of them excused themselves to go assist them. They walked over to the four of them. "Is there a problem here?" Makoto spoke up confidently. Celestine looked at Makoto from Endymion. "This is none your business! So get lost!" She replied to Makoto. "I hate to disagree with you, but when our princess and anyone she seems to like is being messed with in an inappropriate manner such as this, it does become our business! We are in charge of protecting her, as well as wanting to for she is our friend!" Rei retorted. "Yeah, now you release them right now!" Minako said sternly.
"And if we don't?" Celestite challenged. "Don't test us!" Makoto growled. "Ooh, I'm so scared." Celestite taunted. Makoto had enough and grabbed him, slamming her fist hard into his stomach. He groaned as the pain from the hard blow hit him and held his stomach. Celestine glared angrily at Makoto for hurting her brother and released Endymion to go and attack her. Makoto and the senshi were watching him as he stood hunched over in pain and didn't see that Celestine was coming to attack her. As she lifted her fist to punch Makoto, Endymion jumped in the way and took the punch in his jaw. Makoto saw him take the hit for her and glared at her for hitting him during an attempt on attacking her while Serenity examined Endymion's jaw.
She was about to hit the girl when a voice sounded out in sternness for everyone to stand down. The crowd parted and Queen Serenity walked up to where they were. "What is going on here?" She questioned the group. Minako, leader of Serenity's protectors, stepped forward and looked at the queen. "Majesty, these two people were harassing Princess Serenity and her Masked Man. The others and I came over here and told them to release them and leave them alone, but they refused." Queen Serenity moved her gaze from the princess of Venus to Celestine and Celestite. "Is this true?" She questioned the siblings. "Yes, it is true, but we did so cause we want them." Celestine said. "You cannot force someone to do something they don't want to. It is rude to interrupt someone who is dancing with somebody they want to." The queen told them. Both of the siblings hmphed under their breaths.
"Yes ma'am." They said softly. They held grudges against the Senshi and the Queen for getting in the way of taking what they wanted. Serenity and Endymion, deciding that they wanted some time alone, moved away from the other couples on the dance floor and moved out onto the balcony. When they were out on it, they looked deeply into each other's eyes, and he took Serenity's hands into his own. They stood there for what seemed like hours to them while secretly being watched by their stalkers from the ballroom where they positioned themselves where they could see the two.
Out in space heading towards the Moon Kingdom, Beryl and the forces of the Negaverse were moving their forces to attack and get what was needed for absolute power, the Ginzuishou. Soon, a loud explosion sounded outside the palace wall as the Negaverse assault began people started screaming and running to get out of the palace. The four ran over to the balcony and looked at their princess and her Masked Man. "Serenity, you've gotta go some place safe." Minako told Princess Serenity and turned her gaze to the masked Earth prince. "Whoever you are, get the princess to safety." She told him.
He nodded as both he and Serenity wondered what was going. He took Serenity's hand and led her back into the ballroom and through the panicking people to an exit that would lead them farther away from where the attack was occurring while Serenity's senshi went toward where the attack was to stave it off and protect the kingdom. Celestine dragged Celestite by the arm to follow Prince Endymion and Princess Serenity assuming they'd be easier targets since they wouldn't have Serenity's protectors able to watch them. At the battle, the Senshi battled hard for hours, but after a while they became spent of energy, but kept trying to keep the dark forces back.
They were losing ground and were soon pushed back into the abandoned ballroom. Celestine and Celestite tried to find the Prince and Princess, but they had lost track of them as Endymion moved quickly with Serenity, taking her to where Queen Serenity had gone for safety. The Queen looked at them as they entered and Serenity went directly to her mother's side, hugging her tightly glad to see she was safe. Endymion watched and unknown to his love, he knew he had to go help off the dark kingdom of the Negaverse. He made his Tuxedo magically change into his Royal armor. "Serenity. Your Highness. I'm going to go help the Senshi." He told them.
Serenity gave him a sad look not wanting him to go. She wanted him to stay with her and her mother and Queen Serenity smiled at him as if she knew that he was the masked man at the ball the whole time. She knew that the Moon Kingdom was finished as the scouts, Serenity, and Endymion would all be killed in this attack. She and her daughter walked over to her walked to him. "Good luck my Prince." Queen Serenity told him. He smiled at her and looked over at his beautiful princess while she stared at him with her eyes tearing up. "I need to protect you and your mother, Serenity." He told her softly. "I know, my love." She whispered sadly as she walked to him. "Take this with you." She said, taking off her Star Locket and placing it in his hand.
He smiled at her as the locket's music played and then he gave her a gentle hug. "Don't worry. Everything will alright." He told her reassuringly and kissed her softly and she kissed back. He broke the kiss shortly. "No matter what happens, Serenity, remember that I will always love you." He told her. "I will always love you too, Endymion." She said back as she watched her run out of the room drawing his sword to go fight. He fought for a while and saw the four fallen senshi until even he got exhausted during the fighting. Celestine and Celestite saw Endymion fighting the enemies and eventually he fell too. Serenity felt something happen to her prince in her heart and the enemy was practically at the door of the room her and her mother were in.
Queen Serenity decided she would send her daughter through a secret door while she stayed to cover her escape but the princess didn't want to follow her mother's command about leaving her there alone until she was forced to go in it. She had no choice but to walk through the tunnel and exited to where Endymion had fought and was killed. She saw her fallen lover lying there on the floor and she ran over to him, as she began to cry. "Endymion! NO!" She sobbed as she scooped his upper body into her arms and held him closely to her. After a while, she laid him back down, and picked up his sword ramming it into her stomach, and then slumped over his body, dying there with him.
Celestine and Celestite watched her sacrifice and both ran over to them, picking them up into their arms. Queen Serenity, now cornered in the room as the enemy was beating the door to break in felt her daughter's sorrow at the loss of her love and felt her kill herself with his sword. Then she knew that there was only one thing that she could do: Use the Silver Imperium Crystal to seal away the powers of darkness to save the universe and send the prince and the princesses to the future so they could be reborn on Earth and make it so her daughter could get the Ginzuishou should she need it.
She held out her hands and a silver light came out from it, hitting the shadow beasts as they broke through and they were pushed back, sent out and with the power, she sealed them away in a cave on Earth and Celestine and Celestite mistakenly with them while the prince, the princesses, and the guardian cats were put into bubbles of silver light and teleported to the future to be reborn. And after years of being sealed away and numerous assaults by negative forces against their future forms, Celestite and Celestine awoke from the prisons on Earth and sensed the powers of their quarries from the past.
They felt a new power coursing through their bodies, which was that of the Negaverse, and they exited the place of their long imprisonment by teleporting to Tokyo, where they sensed the prince and princess of long ago. They looked out over the city and knew their prey was somewhere in it. They smiled evilly as they thought about having another chance to get their love. They used their new energy to summon Endymion's Shittenou back to life to assist them in getting what they wanted and in turn would let them have the other princesses as reward for their service.
