Prologue

Author's Note: This is word emphasis.

Also, it is canonically stated that Usagi's mother would lock her out of the house and tell her not to return until she studied if she brought home failing grades. If that isn't abusive then what is?

Tsukino Usagi stumbles as she makes her way towards the light she could see in the distance. Her family had shoved her out of their car that was moving at well over the speed limit. The blonde thirteen year old collapses with a thud on the porch of the home with the lights still on.

Emiya Shirou's golden brown eyes widen when he hears a thud on his porch before racing to the front door. He curses under his breath when he sees a young blonde teen whose outfit was torn, there were bumps, bruises, and scratches all along her body. He quickly and efficiently runs his hands gently along her body to see if there was anything truly life threatening wrong with her before he picks her up, carrying her inside. Since her clothes were mostly mangled anyhow he just removes them, grateful her underclothes cover as much as a modest bikini. He gets a bowl with warm water, a washcloth, and antiseptic before returning to his current houseguest. As he cleans her up the redheaded teen finds himself blushing even though he knew damned well he had no other choice. Especially since he didn't want to deal with Taiga's reaction to him taking the girl in.

Once he has her cleaned up and her wounds cared for he carries her to a guest room, lays her down on the bed, before covering her with a lightweight blanket. He leaves the door cracked open so he can hear if she wakes up, and so that she could see where she was. He had no idea if she had a problem with the dark or not. Thankfully school was out for the summer and more importantly old man Raiga would be sending Taiga off on a vacation to Paris around five in the morning. He works on his magecraft, Kiritsugu had actually taught him how to properly access his circuits, along with exercises to increase the amount of power he had available. He reinforces his hearing so he can know if his patient is in distress or not before setting to work. The whimpers were soft at first and could have been from the many bruises that littered her body, it was only when they became more frequent that Shirou went to check on the blonde.

Her head was tossing back and forth while her hands were fisted around the blanket along with her flinching periodically. That was all he needed to see before he goes over to her gently bring her awake. Sapphire eyes bolt open even as Shirou keeps their owner from bolting upwards. He would have thought she'd flinch away from him, instead she relaxed, " Where the hell am I and whose porch did I collapse on? "

" You're in Miyama Town in Fuyuki City and I'm Emiya Shirou, this is my home. "

" Tsukino Usagi, though I won't be keeping that name for much longer seeing as how my loving family shoved me out of a moving vehicle going well above the speed limit. "

" Do you have any other clothes on you since your current outfit is trashed and your current state of attire is a little lacking? " Shirou asks her.

Usagi rolls her eyes, " Everything's still covered, and no I don't have any other clothes with me. I'll be borrowing from your closet, Emiya-san. "

Chapter 1

One year later:

Fujimura Hisa stumbles down the stairs after getting dressed for the day, her forward momentum stopped by Shirou. When old man Raiga heard what had happened to Usagi he had adopted her with full permission from her paternal grandmother. Hisa had long since cut her hair, to the point where it was naturally wavy, and dyed it black while wearing colored contacts in order to keep anyone from finding her. Said contacts turned her eyes forest green. Ending up in such close contact with a teenaged girl had done what Raiga and his granddaughter had thought impossible, Shirou had finally noticed a girl. Damned thing was he was very possessive of her too. None of the Fujimura group would even dare to go after Raiga's adoptive granddaughter

" Hisa-chan, you will never be a morning person, will you? "

" Caffeine and food, Shi-kun. "

Shirou rolls his eyes, even as he shifts his grip on her, wrapping an arm around her shoulders, a year away from her family and of therapy had done wonders for her. Old man Raiga had also tossed Shirou into therapy as well. He had gotten over his survivor's guilt thankfully, constant exposure to a developing teenaged girl had woken his hormones up fully. It had also been discovered that her paternal grandmother had known her granddaughter was unhappy so she had given her permission to have intimate relations. Shirou took this to heart though he kept things to light make out sessions for the most part. Occasionally something would spark a hot and heavy make out session. Hisa leans into him, still mostly asleep.

Shirou gets her settled on a chair and places her hazelnut coffee with a tablespoon of hazelnut creamer and white sugar in front of her. Some life can be seen in her eyes as the scent hits her nostrils. Shirou walks her to school before heading to his own school after giving the middle school guys a glare that they all interpreted correctly. None of them were going to risk pissing off a sixth dan kendo practitioner and ninth dan Kyudo practitioner. Hisa was thankful she was away from her so called family. The year she'd lived with Shirou had been the best of her life. Despite the best efforts of her therapist so far Hisa was incapable of standing up for herself. A lifetime of negative reinforcement was hard to combat.

Shirou was teaching her how to defend herself with swords since her paternal grandmother had made damned sure her granddaughter had mastered Lerdrit and Pencak Silat. Getting Hisa to spar with him was difficult at times because she'd been so downtrodden she never thought to defend herself even if she still trained in her martial arts every day. By disguising the kendo training as a study method he could get her to spar with him nine times out of ten. Old man Raiga had found a teacher for Shirou in his two sword style as well, thus giving Shirou a better grounding in his chosen fighting style.

Hisa yawns as she goes through her first class though she does hand her homework in. While Shirou could keep the boys from messing with her it didn't stop the girls from bullying her. She took it all without complaint which meant her teachers could do nothing unless they saw the incidents themselves. Her hair was pulled, she was shoved into lockers, and on this day she ended up locked in the boiler room after school after being hit over the head with a lacrosse stick. While Shirou knew of Hisa's feelings for him he was still ignorant of the fact that most girls found him rather attractive. Some of those girls were behind Hisa's current predicament. They'd also tied her to the boiler, unaware of the fact that said boiler was very old and on the verge of exploding.

Shirou makes his way to his old middle school in the Homurahara High golden uniform, his uniform jacket loosened enough to see his blue and white long sleeved baseball jersey on underneath. He frowns when he doesn't see his girlfriend immediately before deciding to walk in and chat with some of his old teachers until his reinforced hearing picks up on the whistling of the Boiler. Knowing he doesn't have much time to fix the fussy thing once more he makes his way to the Boiler Room only to find the door locked. In the room Hisa is finally waking up to find herself tied to a Boiler about to go critical. Shirou had taught her reinforcement which meant she reinforces her wrists to break the ropes just as Shirou get the door open. Forest green eyes meet golden brown as the Boiler finally gives in. Hisa's body moves before her mind can realize what is going on.

Shirou watches on in stunned disbelief as his girlfriend just manages to get in front of him before the explosion can reach him, a different explosion happens at the same time, one of power from Hisa. The Tsuki no Hime had woken up to protect her true other half, the lunar royal sigil bursts into brilliant existence, in short order a sailor fuku with super length bows colored black, a blue under skirt, and over that a black edged blue skirt, and blue sailor scarf with white lines, elbow length white gloves edged with three black ruffles, silver heart shaped earrings, a golden tiara with a blue heart shaped gem in the center of it, and in the center of the front bow happens to be a heart shaped blue gem as well. Her medium length black hair still has its wave to it though there were white barrettes with what looked like wings in it. Once the danger has passed Shirou finds himself with his passed out girlfriend cradled against his chest.

He grabs her school bag and hightails it. Once back at home Shirou lays her on the couch, removes her shoes, and covers her with the afghan on the back of said couch. Even he had heard of Sailor V in England. The fact that his girlfriend had awakened a power that allowed her a similar transformation to save him...now he knew how Taiga and the others felt about his self-sacrificing personality. If her power hadn't woken up she would have died to save him. Losing her would destroy him, she gave him a purpose other than saving everyone. He never would have thought she was what was missing though thanks to the therapy he'd been forced into he did have a sense of self-preservation. He brushes a kiss gently across her lips before he goes to the dojo to train.

Juuban:

A black cat with crimson eyes and a yellow upturned crescent moon on her forehead pauses when she feels a wave of untainted power crash over her from quite a distance away. She'd found and awakened Sailor Mars but without Mercury she would not be able to tell where that power came from. The youma were actually easy enough for Mars to handle on her own at the moment.

Fuyuki:

Tohsaka Rin stumbles when she feels pure untainted mana wash over her, before she can track it the power levels out. That generally meant someone awakened a hidden power in a hurry due to life threatening circumstances. In the Matou mansion Zouken suddenly keels over dead even as Sakura feels better than she had in years as the Tsuki no Hime's power washes over Fuyuki. Matou Sakura was quick to pack up every useful magecraft book before she heads for her childhood home. Time to reconnect with her big sister, and kick her ass for not being a better older sister.

Shirou flows through his katas with twin bokken in his hands easily even though he was still worried about his girlfriend. Until she woke up he'd be unable to concentrate on his homework properly. It was as he is finishing his last kata that he catches a glimpse of the very girl he was worried about. He lets his bokken drop as he goes over to her, pulling her to him immediately. He understood why she had protected him, but the fraction of a second where he thought he would lose her was more terrifying than he had thought. " Hisa-chan, try not to scare me like that again. "

" My body moved before my brain could catch up, Shi-kun. " Hisa says softly.

" Where did all that power come from anyhow, Hisa-chan? " Shirou asks her.

Hisa sighs, " Might want to update the bounded fields some more, this is going to be a sensitive conversation. "

Shirou curses, sensitive meant that what was about to be discussed was for his ears only. He reluctantly pulls away from Hisa to upgrade the wards to keep everyone out through simple misdirection. He does call Raiga to let him know to keep Taiga away for the rest of the day. Once that was done he finds Hisa curled up on what had slowly become their bed. Hisa suffered from nightmares so generally at some point during the night she ended up in his bed. Shirou just climbs in behind her, pulling her flush up against him, " Talk to me, Hisa-chan, what was that power waking up anyhow? "

" My past life waking up in a hurry to save us both. In my last life I was the Tsuki no Hime, back in those days the Moon ruled over the Sol System, and I was to become the next ruler. My mother had everything planned out though she misunderstood my trips to Earth, she thought I was going to Earth to see a Prince. Instead I went to see the Flora as not much can grow on the Moon. By forcibly engaging me to the manwhore prince whom bedded four of my guardian senshi not to mention my mother she brought about the end of our Queendom. Only Earth retained any semblance of life. My guardians were the princess of the planets, you've already heard of one of them, Sailor V or rather Sailor Venus. I was never trained in how to fight, I was raised in a gilded crystalline cage. Not even taught how to use the noble phantasm of the line, the Crescent Moon Wand. Most made the mistake of thinking that the Ginzuishou's the noble phantasm, that couldn't be further from the truth. The Ginzuishou is the Star Seed or life force of the current ruler, my mother didn't have one, instead she used mine since the core of it's power was still inside of me. "

Shirou remains quiet as he processes all of this even as he presses a kiss on her collar bone. " None of that matters. It doesn't change who you are. It doesn't change how I feel about you, Hisa-chan. "

" It does matter since Venus is active, it means the seal on Beryl and Metalia is breaking. It means I have to fight. "

Shirou rolls over to gently rest on top of her, " Who said you'd be fighting alone? I'm sure Zelretch would be more than happy to turn me into a magical boy. "

Yes, they had in fact met the Wizard Marshall, he'd continued Shirou's training in magecraft. Hisa didn't want to fight yet she wanted to protect the innocents. While he knew she had permission there was no way he was going to take their relationship into intimate endeavours before she was sixteen. Unless she actually started it. He lowers himself just enough to kiss her, Hisa was very much a submissive personality type, which concerned him. It was also why he never left her alone with Tohsaka Rin. Hisa never started anything with him, he hoped that one day she'd actually be capable of initiating a make out session. He rolls them over when his hands itch to touch her.

As he deepens the kiss his hands skim up her sides before slipping under her uniform top. While Hisa never started anything with him she was in fact a full participant, her hands were busy tracing his abs, causing him to groan. It was when they broke the kiss to breathe that he saw her smirk, " You minx, you did that on purpose. "

Hisa just smiles before pulling him up, his uniform top and shirt being discarded immediately. Shirou shudders from a combination of the cool air hitting his skin and arousal, as Hisa's hands were not idle. It was only when they run through his hair that his hormones really sit up and take notice. His whole body shudders as her fingers skim along his scalp, barely able to keep himself upright. His hands find the clasp to her bra, flicking it open with some difficulty before they move along her torso, and up higher to cup her assets. Then he breaks away from her long enough to send her uniform top flying. The bra was the next to go, getting dropped over the left hand side of the bed. He quickly closes his mouth over one of her breasts while his right hand takes care of the other one.

His free hand skims down her body, skims her outer thigh before going inwards, travelling up her skirt. He flips them over again, letting his hormones take over. He drops onto his half naked and satisfied girlfriend, he only needed to wait another two years before he could finally claim her fully. Still, anyone that had known him before Hisa came into his life would be shocked that he was even capable of dry humping his girlfriend. As Hisa's chest was against his own he really didn't feel like moving anytime soon. Still, they had to do their homework, eat, and train.

" Don't suppose I can convince you to sleep topless tonight, can I? " Shirou asks her.

Hisa giggles, " You just want an excuse to have my naked chest pressed into yours. "

" Hell yes I do! I'm a teenaged guy, dammit, and very firmly straight. " Shirou says, not even denying.

" Maybe, depends on if you can keep me warm enough. " Hisa says.

Shirou's brain stalls for a few seconds before rebooting, " Where the hell has this side of you been hiding anyhow? "

Hisa grins, " The Hime awakening tweaked a few portions of my personality. You'll be finding out that I will now be more than willing to start things up between us. I'm also quite willing to kick your ass across the dojo as well, Shi-kun. "

Shirou gets to his feet, pulling her up as well before tossing one of his shirts to her. Taiga was well used to seeing Hisa in one of his shirts since she seemed to prefer them, especially for just lounging around the house. Taiga had been the one to take her shopping for new clothes once she had gotten back from her vacation. Until then Shiro had altered some of the clothes he had outgrown to fit her better. Neither teen even felt the slightest bit of embarrassment changing in front of the other since Hisa actually had no sense of modesty, she just complied with societal norms. Shirou had long since gotten used to this, once they'd started dating, he'd given up on maintaining his modesty.
