Sailor Moon & OOO: Of Hearts and Medals

Author Note: This is a crossover between Sailor Moon S and Kamen Rider OOO. Both Storylines will intertwine and challenge both Senshi and Kamen Rider alike. I hope you enjoy the story, and please Review afterward, I'd love to hear from you all about what you think, and I will warn you now I will be using at least one or two original characters in this.

The Prologue: A Prophecy of Danger and An Ancient Awakening

The city was draped in darkness, and an eerie red light prevailed through the land. People frozen like statues were in front of them. At the same time strange coins seemed to fall through the air and litter the ground. In the midst of all of this, a single girl stood and watched it all. Behind her, a large light pierced the darkness, as she looked, the light split into three and flew off vanishing as the darkness came forth and consumed all in it's path.

And then the girl woke up...

The girl that seemed to snap out of a daydream was sitting with books in front of her. At the same time she had a girl next to her whom instead of daydreaming...seemed to be really dreaming. It caused the girl to sigh in annoyance.

"Is there something wrong wrong Rei?" asked a girl with short blue hair.

"Did you have a premonition?" asked another with long brown hair.

"I think I might have but it was really noisy too." said Rei as she took her head in her hand. "This one was majorly weird."

It was then the sleeping girl sat up and said...

"Talk about weird dreams, I just had a doozy. I had a dream that I was pigging out on ice cream and I had to go to the doctor and guess who was there with me? Mamoru...he had to go because he ate too many of the cookies I made. Oh wait...that really happened." said the blonde girl as she held the back of her head with a hand and laughed.

The girls that sat around the table sighed as they looked at her.

"I hate to nag, but we are here to study not sleep."

"Dont tell us you were happy with mark on your last test, are you Usagi."

Usagi couldn't help but sigh...she knew very well what they were talking about, but looked to the brighter side of things as far as she was concerned when she said.

"Well I know I got at least one right." she said with a nervous laugh.

As the conversation continued, Rei couldn't help but get the vision out of her mind. What was that evil force she was feeling, and what of the three lights, and the coins that were everywhere. What did it all mean?

…...

Later that evening, in what seemed to be a large laboratory. A man stood in front of a desk as a concoction started to boil as a shape formed with in. It was then the container exploded and a strange seed like capsule appeared.

"Kaolinite, come here..." the man said.

"Yes, Dr. Tomoe?"

"My newest creation is finally complete. With this diamond pod, we will be able to steal pure hearts." called out the man known as Dr. Tomoe as he flung his head back laughing sinisterly.

"Pure hearts?"

"Yes...inside chosen pure hearts are objects of great power that shall lead us to all mightiness. And when pure hearts with special qualities are found they will reveal items such as a charm or a jewel and when three of these objects are brought together, they will open the path to unlimited power!"

"So when you find three objects from pure hearts..."

"I shall hold the entire world in my hand!"

"Kaolinite, I want you to go out into the city and find us a pure heart that contains the crystals. I shall send out my diamond pod, and it will create a heart snatcher. It will find a target and steal their pure heart."

"At once..." Kaolinite said as she vanished in a flash leaving only her lab coat behind.

At the same time, he allowed the pod to float up toward a pipe before shooting off like a bullet, and then firing out of a secret panel beneath the sidewalk. It flew off looking for it's target...the laughter of the doctor echoing through the night.

…...

The next morning across town at the Kogami Art Museum, two guards were currently using their position to attempt to steal from the museum before it's grand opening. As they broke in, they began to check out the items in storage to get their pick of the best they could steal, as the sun slowly started to rise.

"Haha, this is amazing and it's all ours." said one of them as they picked up a priceless plate.

In the back of the storage area however, was what appeared to be a solid stone coffin. Behind that however was a small pile of silver medals. As the guards continued to rummage through the artifacts, the pile of medals began to move and moved itself up the side of the coffin. When it reached the top, the pile formed into the shape of a hand as it reached the center where it gripped the piece in the center then turning it making a clicking sound as he lifted the piece off of it.

This caused the coffin to begin to glow with a golden glow. The Guards where shocked to see it as after a few flashes of gold, the coffin broke down into what appeared to be thousands of silver coins, which then formed into four humanoid looking figures. With a scream both guards backed off scared for their lives as behind them the wall was broken as a man on a motorcycle had appeared, drawing a shotgun and opening fire on the coin creatures, doing seemingly no damage, as the thieves ran for their lives.

"This is Gotou of the First Ride Vendor Platoon, the Medal Awakening has begun. Your orders?" the Rider said as he touched a communication device just under his helmet.

…...

In an office, a man in a red suit and a kitchen apron stood there mixing what seemed to be cake batter as a woman held utensils for the man to use. As he pressed the talk button on his end of the receiver.

"Destroy them" he said as he used his finger to get a bit of icing off of his face.

"Yes sir."

…...

As the rider went outside as the creatures approached, they glowed with a different color as the creatures took a new form. The first was a seemingly muscle bound being with a head that looked like an elephants and legs that were similar. Next to him was less stocky creature wearing black body armor with yellow accents with a pair of claws on his wrists, a head of a feral cat with what seemed to be like dread locks flowing down making it seem almost like a lions mane. Next to him was a feminine creature, with legs that seemed to be designed like an octopus, with a cape around her neck, and a head shaped like an Orca. Next to her was an imposing being made with images of Bugs wearing Green and Black armor, with claws on his hands and a pair of antenna on his head, and the horns of a stag bettle. These four marched towards the hole made as a whole platoon of riders were now waiting outside.

Taking aim with the command of their leader, they fired on the building with Rocket Launchers, as the rider known as Gotou pressed a detonator to fire explosives set in the building to ensure it's destruction and hopefully the destruction of the monsters now inside of it.

This proved in effective, as three flying streams of medals flew from the hole as the elephant headed monster walked through it with no issues as the building came crashing in. Giving the orders, the Platoon split off each perusing a different target. In different tunnels nearby, each of the monsters stood prepared to face their pursuers. The bug creature leaped with incredible height and crashed into two riders as they came at him with full speed, before taking the third and slamming him against the side of the tunnel. The cat monster took hold of two that were riding by him and flew out of the tunnel and slammed them into the hood of a car nearby. In another tunnel, the female creature stood holding her hand out as a torrent of water rushed from her hand creating a rush of water similar to a powerful fire hose knocking the three perusing her off their bikes. Meanwhile, the Elephant headed monster stood ready letting them come to him. With a stomp of his foot the ground thrusted up beneath the bikes sending them flying before exploding behind them. In the aftermath, the monsters stood triumphant before they vanished from the area.

Back at the office of the man in the red suit, an old record player was playing a record with the song "Happy Birthday" on it as he man finished the decoration on the cake he had been working on.

"Happy Birthday...Greeed..."

Placing his icing pipe down, he walked around his desk and then stood in the middle of his office as he sang with the record...

"Happy Birthday...to...Youuuuuuuuuuuuuu!"

…...

At the area of the museum in the aftermath of the battle, a crowd had gathered as did medical teams and the police. Walking up to it was one particular student that had seen it on his way to school and came to see what happened. As he arrived, he said...

"What happened here? This is terrible...huh?" he said in surprise as he felt something under his shoe.

As he looked, he saw a red and gold coin beneath his foot. Picking it up, he dusted it off and looked at it. It had the design of what looked to be a hawk on it. Thinking it was a new kind of collectable he placed it in his pocket...near him were Usagi, Ami, Rei, Minako, and Makoto. The five of them couldn't believe what they were seeing here.

"What in the world caused this?" asked Makoto as she looked at the destruction.

"I dont know but I sense some really bad vibes here. What ever happened here it wasn't any normal explosion, it couldn't have been." said Rei as she looked on...'This couldn't have something to do with my vision could it?'

"We'll have to keep an eye out for anything about this explosion. If this wasn't a bombing, we may very well have a new enemy on our hands...but what could be here that they would want so bad?" said Ami.

"Well, there's nothing we can do about it right now girls, you should head off to school till we can find out more." said a voice as a cat hopped onto Usagi's shoulder.

From a more further off view, two figures stood watching the scene themselves, for them this was not expected and they knew that nothing good could have come from this. In fact, it may have very well made things much worse than they were.

"A bad wind is brewing from this...whatever happened here it may impact our mission."

"We must complete our mission, no matter what twists may occur. We should go."

The two figures began to walk off into the shadows as Usagi looked at her watch

"Oh No! We're gonna be late!" cried out Usagi.

At the cry, the student that had picked up the coin turned looking at the group of girls he didn't notice till now.

"Is that Tsukino-san and her friends?" he said as he looked at his watch "Oh crud! She's right we're gonna be late, better go with them."

At the same time, a bit of the rubble that was near the boy shifted as what appeared to be a Red forearm with a bird on it crawled out. It's fingers pointing in the direction of the boy that ran off as he started to float to follow him.

"This is not how I wanted to start out my day, first we hear about this tragic incident at the museum that is going to open and now I'm going to miss time to start studying early." said Ami as they ran.

"You're telling me, I was gonna get in a bit myself but now we gotta rush to beat the gate!" yelled out someone behind them that was catching up.

Turning they saw a boy from their school following them, obviously having been at the scene as well.

"Hey, aren't you Tsuzuki-san from our class?" asked Makoto as they ran.

Turning he smiled and waved as they ran.

"Yeah, Tsuzuki Shinji, nice to get acquainted thought I wish it wasn't while we were rushing to be on time...I heard about the explosion and couldn't help but see what was going on, I just hope no one was hurt." he said.

"From what I heard there were two people hurt but not seriously." said

It was not something one saw everyday and like most humans curiosity got the better of him and he wanted to see what happened. But little did he know that picking up the Red coin that he had found, would not only change his destiny but intertwine it with the very classmates he now ran with. As Rei broke off to run for her school, she waved to her friends but then got a strange feeling off of the guy that had met up with them.

'There's something strange about him...I dont know what but maybe I should ask the girls about him later.' thought Rei as she headed off for school, only to miss the floating red hand that was also following the group heading to Usagi's school.

Shinji continued to run with Usagi and her friends as they approached their school...with the red floating hand following right behind them. For what purpose, no one knew at this point...

A new battle was brewing between good and evil was beginning to brew from two fronts and soon the Sailor Senshi and one Shinji Tsuzuki would take part in a battle that would change them all forever...
