I wondered what a dark version of Sailor Moon would be like an I thought of Madoka Magica, I decided to combine the two and make Kyubey contract with the girls of Sailor Moon. Hope you enjoy this. :)

Prologue

Kyubey blinked and opened his eyes and looked around, his usual expression still pinned on his face. He realised he was on the moon but this wasn't the moon from his universe. This moon had a crumbling city on it.

'This isn't my world.' he thought to himself. Kyubey wondered how he arrived at this unfamiliar place. He racked his brain but the only thing he could remember was his purpose: to collect energy to save the universe by harvested human emotions.

'Yes that's right, I was sent to earth wasn't I? I made contracts with teenage girls; I granted them a wish in return for their souls. They became magical girls to fight witches until they inevitably give into despair and become witches themselves. I then collected the emotions that burst out of them when they turned into witches and I made it into energy.' Kyubey thought. Now he was getting somewhere, but what exactly happened?

The last thing Kyubey could remember was making a contract with a potentially powerful magical girl named Madoka, she wished that all the witches were destroyed before birth in their world.
'Oh no...' Kyubey realised that the incubators plans were ruined but there was nothing he could do. He had to grant Madoka's wish, and he did... but then what happened?

He remembered Madoka becoming a magical girl, saving all the witches and then becoming some sort of goddess, then what? He remembered other magical girls he recently made contracts with like; Nagisa who became a witch, Mami who was killed by Nagisa as a witch, Sayaka who also became a witch, Kyoko who killed herself while killing Sayaka as a witch after Kyubey told a little white lie and... Homura, a magical girl who apparently made a contract with him in another timeline and wished to go back in time to save Madoka. She was trying to kill Kyubey in order to save Madoka but he couldn't be killed. That was all Kyubey could remember. He couldn't remember how he got here but he figured it either had something to do with Homura's time-meddling or Madoka re-writing the whole universe or maybe it was both combined.

Kyubey walked around trying to figure out what to do when his thoughts were interrupted.
"Meow." Kyubey heard two meows come from behind him. He turned and saw two cats staring at him. One was black and the other was white, both of them had a strange golden crescent on their heads
'Oh yes those creatures from earth that humans keep as pets.' He thought.
He was about to walk away but one of the cats started to speak.
"What sort of creature are you?" A female voice came out of the black cat's mouth.
"You can talk?" Kyubey asked.
"Are you not from here or something?" The white cat spoke in a male voice.
"No I'm not." Kyubey answered.
"I'm Luna and this is Artemis we are advisors of our Queen." The black cat purred.
"I'm Kyubey, I'm an incubator." Kyubey introduced himself.
"What's an Incubator?" Artemis asked.
"An incubator makes contracts with magical girls to collect energy." answered Kyubey.
"Really?" Luna gasped. "We could use someone like you. We are about to be put to sleep for a long time and when we wake, we will find the re-incarnated Sailor Moon and the Sailor Scouts. We will then advise them while they fight against monsters who steal energy and the evil Queen Beryl and the Dark Kingdom. If you are on our side then could you could help us awaken their magical sides by making one of our contracts and help us understand the energy stealing?"
"As you can see we are desperate! We don't know how else to awaken the real Sailor Moon and the Sailor Scouts. I know this is fast but could you please join us in our slumber?" begged Artemis.
"It's ok, I'm used to making things quick" Kyubey chirped.
'This is great! I can collect energy from these Sailor Scouts while I figure out if the other incubators are here.'
"So what do you think?" Luna asked.

Kyubey looked at the two cats looking at his expectantly. He stared at them with his usual emotionless face and asked;

"Do you think Sailor Moon and the Sailor Scouts could take on witches?"

This was just the prologue to get the plot started and explain where this story takes place. It's going to get more interesting in the actual chapters. Please review with either positive feedback or constructive criticism. :D
