AN: This idea came out of nowhere. Well actually it came about after I read this manga called Yomeiro Choice. It's about this guy who's daughter from the future suddenly comes and is trying to preserve her existence by making sure that he marries her mom…or at least ends up impregnating her. Matters get more complicated when another daughter shows up with the same goal. It gets pretty wacky.

So, I decided to implement this idea with our dear cast of Nanoha. How will the White Devil react when all of a sudden Fate's supposed children start popping up from the future trying to make sure they are born? Expect lost of chaos for sure. Hope you enjoy.

Warning: This is going to be AU-ish. I say that because they will still all have their magic powers and everything through Nanoha A's has taken place. So in this story they will be in high school. I'm pulling characters from Striker's and Vivid and placing them on Earth in order to do what I want. So, yeah, I hope you still enjoy it.

Science Plus Magic Equals Children!

Ch.1 I'm Your Daughter!

It was a fairly normal day in Uminari City. Fate, Nanoha, and Hayate had just finished another day at school and were now walking home together. They had decided to go to Fate's house so they could work on their homework together. Plus it was a good excuse to hang out. Sometimes, it was hard to find time like this with their TSAB duties getting in the way.

They reached Fate's home in no time and began to work on their assignments.

'Has Fate-chan always been so…pretty?'

Nanoha's mind was nowhere near her homework. All her brain cells were busy exploring the beauty that was Fate T. Harlaown. Recently, Nanoha had come to terms with her growing affection for the blonde haired girl. She'd always know that Fate held a special place in her heart. She just hadn't known what it was exactly. She'd never been in love before so it wasn't something that had crossed her mind. Up until recently, she was content with the friendship she'd forged with Fate.

So what changed? One word: puberty.

Those inevitable teenage hormones hit her like a bullet train. She suddenly found herself gazing at the blonde for no particular reason. These bouts of staring were becoming frequent as she began to realize that Fate had turned into a gorgeous girl. She started to notice little things about Fate that she'd never noticed before. Like when the sun hit her at the right angle, she would obtain a halo like glow. Or how their hands so easily molded to each other's and the way she'd smile for her when they were alone. Did she mention that Fate had a body to die for?

Sometimes she'd stare at those long creamy legs that seemed to go on forever…She discretely wiped away some drool that had started to form. A snicker to her left however let her know that Hayate had most definitely noticed her admiring their friend.

Hayate was one of the first people to realize that Nanoha's love for Fate went farther than just friendship. She wasted no time in teasing both girls about it. Thanks to this, all of their friends had come realize it as well, everyone except Fate that is.

This frustrated Hayate to no end since, as she once said, Nanoha was practically undressing Fate with her eyes every chance she got.

No one was sure how long Nanoha could go on like this. They had a betting pool going for when the brunette would crack and pounce on the oblivious blonde.

"Would you guys like something to drink?" Fate asked like the good hostess she was.

"Sure!" They both responded.

"Is tea okay?"

"Of course!" Nanoha replied while Hayate nodded.

Fate smiled at them as she stood and headed for the kitchen. Leaving the two brunettes alone, Hayate took this chance to pick on Nanoha.

"You know, it seemed like you were aching to eat a certain someone."

Nanoha's face immediately flushed red.

"Hayate! You're making it sound so…dirty."

"Haha, oh Nanoha. Your reaction never fails to entertain me. So when are you going to confess?"

"I-I'm just waiting for the right moment."

Hayate sighed. At the rate those two were going, the right moment would take another 10 years! It didn't help that she couldn't read Fate's feeling towards Nanoha. That girl had an impenetrable poker face. It seemed like the only way for progress to be made was for something drastic to happen in order for Nanoha to confess her feelings.

"AAAAHHHHH!" A scream suddenly came from the kitchen.

"FATE-CHAN!"

Both of the girls ran towards the kitchen with their devices in hand ready to defend their friend against any danger.

When they arrived, they found Fate lying on the ground with a little girl on top of her. She looked to be no older than nine. The girl had light brown hair done up in pigtails. If they didn't know any better, she looked like Fate when she was that age. Other than this odd sight, there seemed to be no one else around. Since there was no other sign of danger they set to waking up the two girls.

After a few shakes and pokes, the two girls groaned. Hayate and Nanoha stood aside and let them come to their senses. Fate sat up first and looked around confused. Seeing that Nanoha and Hayate were there she relaxed a bit. A groan brought her attention to the child resting on top of her. The girl slowly opened her eyes and looked up at Fate. Burgundy met ocean blue.

"Fate-papa!"

Those fateful words caused Nanoha's heart to shatter into a million pieces. HER Fate had a child! How? When? And more importantly, with who? Once she knew who, she'd Starlight Breaker them out of existence and make sure Fate knew exactly who she belonged to. Hayate sensed the dangerous aura coming from Nanoha and scooted a bit further away.

"P-papa?" Fate squeaked. "N-No, there has to be some mistake!"

Nanoha felt a bit relieved to hear that. Fate seemed just as shocked as she was. That meant she was innocent right? But what if she wasn't? What if she was like some of those men who denied their own child to avoid responsibility?

'NO! My Fate-chan will take good care of our future children!'

"Fate-papa, it's okay. I'm actually from the future! I'm here to make sure you and Mama get married so that I don't disappear!"

The revelation left them all equally stunned. Was that even possible? They were given no time to recover as the girl took notice of the other girls in the kitchen. Her eyes shined with glee as she laid eyes on a certain brunette.

"Mama! You're already here!"

Hayate never felt so terrified. The Book of Darkness incident had nothing on this new threat to her life.

"Raising Heart." Nanoha said with barely suppressed rage.

"Stand by ready."

Hayate looked on in horror as her barrier jacket replaced Nanoha's school uniform. At this point, Fate had jumped up to her feet in order to stop Nanoha from killing their friend.

"N-Nanoha! Just wait! T-This isn't...I don't like…" Hayate tried in vain to plead her case.

"Fate-papa!" A different voice rang out.

Nanoha's attempted murder was halted as she turned to see a different girl hugging one of Fate's legs. This one had blond hair and heterochromatic eyes. She then turned to look at Nanoha and gave her a smile that made her heart melt.

"Mama!"

The little girl ran towards the stunned brunette and hugged her. Fate gaped openly at the two little girls who not only claimed were her children, but also the children of her best friends. It was like something out of a talk show. A very horrible talk show. Both girls then turned to look at her.

"Please marry mama now!" They both exclaimed.

Hearing those words, and along with everything else that happened, Fate reacted the only way she could. She fainted.

AN: And there you have it. Fate's life just got infinitely more difficult (and entertaining). Next chapter, we meet the two girls who are eager for Fate to marry their mama's and another girl shall be making an appearance causing not only Nanoha to want to go into another murderous rage, but a certain blonde healer to seek blood as well.
