Prologue- Usagi's Guardian Angel …er… Demon!

Before the Silver Millennium...

Two human figures powers collided together in the ruined and scorched earth as they both fought in a deadly duel. This was before the Silver Millennium, many people of the Moon Kingdom knew of the story of the first Serenity's battle with a powerful demon. When she defeated the demon she sealed him into the Silver Crystal itself trapping him forever until he was freed of someone of Serenity's family bloodline. Only a few had known the demons name. Though Serenity had kept the name sealed in scrolls and books along with the demon's possessions. However, because of her famous battle with the demon, the people of the solar system had chosen her to be their queen. And thus, the Moon Kingdom began, and then slowly, but surely began the start of the Silver Millennium. When the Senshi were to arise, the first Sailor Pluto predicted that the demon would rise again and be free, causing many to fear for his return.

After Beryl's assault on the Moon Palace, Silver Millennium...

Serenity the Fifty-first laid down on a slab of stone that had once had been a wall in exhaustion. Her breathes were ragged and shallow, she knew she was to die soon on the once lively planet which was now a dead world. She smiled as she looked up at Earth, knowing that she saved her daughter and the other Senshi, however she felt her energy leaving her. In her hand was the moon wand, which she saw a human like figure looking at her. She watched the Silver Crystal pulse and she began to concentrate her thoughts into the jewel. .
The demon within the crystal only stared at her as she slowly dies, he had watched everything for many millennia, seen every Serenity born and died, yet this was the first time he had seen a Serenity die so young. Suddenly he felt the seal that contained him removed pulled back into reality.
In a flash of light, the demon was free from his ancient imprisonment. He concentrated his gaze on Serenity as she looked at him in a serene face. Darkness concealed most of his body and only his outline and his sky blue eyes could be seen. Both were silent for several moments as they stared into each other's eyes.
"Why did you free me?" He finally spoke.
Serenity looked at him sadly, her eyes brimming with tears.
"I don't want to die alone"
He looked at her, not showing any expression, nor feeling. Then he slowly bent down next to her. Never thought I would show any kindness. Heh, I must have mellowed out these past centuries He thought. He held her hand as she struggled to breathe and wiped the tears from her beautiful face.
"Your possessions are in the armories" The demon gave her a bewildered look. "It's under the throne room"
"Why are you telling me this?"
She looked at him.
"Please help my daughter" Her breathes grew shorter. "By your honor promise me you will," Tears fell from her cheeks as she struggled to breathe and the pain she felt was overwhelming.
He wiped away her tears again and kissed her on the forehead. His cold expression faded away leaving a gentle smile.
"I promise"
Serenity smiled.
"Thank you Ranma"
Those were her final words before she passed on and the Silver crystal shattered in her now still palm. The shards then flew toward Earth, the shard became known as the rainbow crystals that Senshi would hunt down later in the future.
Ranma buried Serenity's body within a once beautiful garden and walked toward the throne room. Ranma opened his hand, pointed it to the ground. An intense energy blast erupted from his hands and destroyed the marble flooring. Jumping down into the newly made hole, he quickly looked around the room and picked up a small black shield, which was emitting dark energy. Then a small scythe like weapon with a chain attached to its base (Think of Anubus' weapon in Ronin Warriors) which glowed with violet light. Finally, he put on his black and red armor. (Think Tekkaman minus the helm) The sun raised from the moon's now barren horizon finally reveals Ranma's body. Atmosphere was now seeping away into the void of space.
Ranma looked completely human. For several moments he admired the scene of Earth. He suddenly felt a presence of someone behind him. Ranma wasn't worried, he knew who it was.
"Hello Pluto" He turned to the Senshi of Time giving a savage grin. "What do you want?"
"If you dare threaten the Princess I will... "
"Feh... You know that I value my honor before anything else. Anyway she won't know that I am protecting her if she doesn't see me" Ranma shrugged his shoulders giving her a menacing smirk.
They both stood there, trying to glare holes in each other in silence before Pluto vanished and Ranma raised his right arm. In his right hand was a small shard of the Silver Crystal floating in his palm, he knew that the Silver Crystal would not work at full power without this shard. He shrugged, he would return it if the Senshi need it, but until then he would keep it. He waited for centuries within the ruins for the Princess' rebirth and occasionally went to Earth when he became bored. Then he felt eleven Silver Millennium energy types on Earth, two on the United Kingdoms and nine in Japan. Ranma grinned as launched himself from the Moon's surface and flew toward Earth glowing brightly as he hit the atmosphere.

Meanwhile at the same moment…

Ikuko smiled as she and her husband, Kenji, looked down at their new daughter.

"Look Ikuko, it's a shooting star" Kenji said as he looked out at the night sky. Ikuko looked out the window of the hospital they were in and looked out at the falling star (who's Ranma by the way). Soon her gaze shifted to glowing full moon and inspiration hit her which caused her to smile.
"Usagi"
"What dear?" Kenji turned to look at his wife.
"Her name will be Usagi" She smiled happily.
Kenji smiled back. "Yes, Usagi is the perfect name for her"

Years later, during Beryl's attack on Earth...

"Owe" A burnt Ranma laid on face after teleporting in front of a fire ball to protect the Princess making looked like she 'tripped' on her own feet.

Black moon family attack...

"Now I know why she hates that runt" Ranma was in the Channel after chasing Chibi-Usagi to get the silver crystal back to Usagi. Chibi-Usa had suddenly turned a corner as she ran off with the crystal and he was sure that he could have tackled her, get the crystal, and erase her memory.

The Doom Tree attack...

"That was a bad idea" a bruised Ranma limped after pushing the Princess out of the way of an incoming attack of vines with sharpened tips.

The Death circus...

"Urk!" A cut up Ranma fighting a vulture demon before Sailor Moon and her Senshi arrives knowing that it was too powerful for them to handle. The Witches episode...

"Dammit why me!"

The Galaxia series...

"Now its official, I'm an idiot for even agreeing to this!"

The present...

Ami typed on her Mercury computer looking up files on their past battles and find something strange. She noticed a black image in practically every battle the Sailors have encountered. She rapidly typed to a battle, seeing it push Sailor Moon out of the way making it look like she tripped and many other times she managed to be safe by maker Sailor Moon look clumsy. She closed her computer; she needed to tell the others of this.

A few minutes later...

Ami already explained what she has discovered.
"So you're saying that someone or something is protecting Usagi in secret?" Rei asked. "And that she wasn't a klutz all the time"
"Waaaah! Rei you're such a meanie!"
"Quiet meatball head!"
Ami nodded and showed the images on her computer to the other Senshi in hopes of quieting down the two.
"Maybe Setsuna knows" Minako suggests.
"I do, but I cannot reveal that information at the moment" Setsuna appeared behind her although she was suppressing an evil smile that scare all the Senshi.
"Eeeek! Stop doing that!"
"Maybe we can set a trap?" Luna asked.
"I guess that would work" Usagi said.

A day later...

Usagi, Makoto, and Ami was walking around a neighborhood district after a day of shopping and visiting the arcades. Usagi crossed the street and a bus suddenly turned the corner in high speeds. Usagi froze as the speeding machine came toward her. The dark figure teleport next to her to push her to make seem to trip only to be tied by a heart shaped chain. The bus went through the both of them. It took a few seconds for Ranma to figure out that the bus was really a hologram. He looked over to Sailor Venus holding on the other end to the chain.
Usagi and the rest of the Senshi looked at Ranma with curious faces. Minako and Makoto, however, had hearts glowing in their eyes that made Ranma nervous. Ranma looked to the other side seeing Setsuna smirking at him with the look of "got ya". Yup. He was definitely and royally screwed.
"Awwww crap" Ranma deadpanned.

Authors notes

Yep! I rewritten this after rereading it and thought it had too little detail and left several things out.
