Hello.

Actually, I've made a crossover of Sailor Moon and Fate/stay night once. But it takes places in Fifth Holy Grail War where Illya our loli queen is still a merciless psychopath and suffers most. Since I don't want to make Illya suffer more, I decide to change the story... Plus, I want other Servants and Masters to meet the Sailor Senshi fast... So here's the new story!

This story takes place months after Fate/hollow ataraxia and a year after Galaxia Arc.

Enjoy!

Prologue: Night of Fate

"Then Usagi tripped her foot before she could even kick the ball-"

"Waaah! Why do you always commemorate my moment of shame, Minako-chan?!"

On a Sunday night before a normal school day, all Sailor Senshi gathered in the Outer's mansion. They were celebrating Makoto's new position as the new president of cooking club. The cooking expert was so happy that she wanted to cook a delicious dinner for her friends as a treat. Everyone decided the Victorian mansion was a perfect place for Makoto to serve her magnificent food rather than her apartment-in terms of accommodation.

After dinner, they decided to play and chat some more as Minako told everyone about Usagi's soccer attempt days ago. Haruka stiffened a laugh and Rei was laughing her ass of at the sulking bun-haired girl. Setsuna was helping Makoto with the dishes. "You don't have to feel bad about it, Usagi," Ami tried to cheer her up. "After that, our team was able to score a goal because the goalkeeper was too busy laughing at you, right?" she mercilessly added.

"Ami-chan..."

"...The rescued victim confessed that a blackout suddenly occurred on the night street he's in. He's almost got taken by a mysterious person cloaked in black before an unidentified person called him out of danger. But before he could see everything clearly, he suddenly lost consciousness so he couldn't identify the culprit nor the savior..."

All eyes went to the TV after Hotaru turned it on. Originally, she wanted to watch a comedy show to add their amusement. She could not guess what kind of channel that'd pop out first. It turned 180-degrees instead.

"...I'm sorry," the twelve-year-old apologized, feeling guilty for changing the atmosphere. "There's nothing to apologize for, Hotaru," Michiru got up from the couch beside Haruka to pat her head gently. Everyone stayed in comforting silence for a while.

"Well, that's decided," Haruka suddenly cut in and got up. "Time's up, girls. You've got a brand new school day tomorrow. I'll take you home," she went to get her key car. Rei and Ami agreed by sending her a smile. They knew Haruka must be worried about them after watching the news.

"Awww!" Minako whined loudly, "Can't I just be absent from school for a while?" she wondered and followed by a nodding Usagi. "Mina, you've done that five times," Makoto pointed out from the kitchen. Minako grumbled and Usagi butted in, "Then I can-"

"Three times, Usagi."

"Uwah!"

"I'll go as well," Setsuna came out from the kitchen with Makoto, cleaning her hands with a napkin. "Some of you can get in my car rather than getting cramped on Haruka's."

"My Lamborghini is not cramped," Haruka retorted after coming back. Setsuna rolled her eyes playfully, "It's designed for four people and you want to bring six people at once?"

"It's fast, unlike a certain antique car that I don't know it still functions," Haruka smirked.

"I can crash your cars into each other if you want a competition so why don't you take our guests home now?" Michiru suggested with a smile.

So the victor was none other than the violinist. Both Haruka and Setsuna gulped and nodded in defeat. Hotaru giggled at her parents' antics. "Setsuna-mama, Haruka-papa, you're silly," she said and followed by everyone's laugh. Thankfully, the tension disappeared. Rei dragged the whining Minako while Makoto used the last piece of her snacks as a bait for Usagi. Everyone gathered at the mansion's entrance to bid each other goodnight while Haruka and Setsuna got their beloved cars. Michiru and Hotaru stayed in the mansion.

"Hey, can we go past the mysterious castle that's built in Azabu Juuban?" Minako asked eagerly. "It's quite near from Rei-chan's shrine, right?"

"Not right now, Mina. It's late at night!" Rei objected.

"You're no fun!" Minako went back whining.

"Bye-bye!" Hotaru waved her hands energetically to the moving cars that brought her parents and friends in it, in contrast to Michiru to waved her hand gracefully. After that, the sea goddess brought her daughter in to help her clean up a bit. The first thing Hotaru did was turning off the TV then helped her mama while chatting a bit.

"Have you done your homework?" Michiru asked a very mother-like question while cleaning the table with Hotaru. "Yes!" the little girl proudly nodded. "I only need to change into my pajamas and brush my teeth before I sleep," she added, chuckling a bit after finding Usagi's remnants of snacks.

"Aren't you a good little darling?" the aqua-haired girl lovingly poked her daughter's cheek who squealed in response. "I guess I really shouldn't worry about leaving you tomorrow," she added. Michiru and Haruka was asked to perform a duet in a prestigious party of Japanese aristocrats tomorrow. It's quiet important for them because their patrons would be present. They'd leave in the morning and came back probably a day later.

"You don't need to worry about me, Michiru-mama. I'm already twelve years old and actually older-"

PRANG!

"Well, that has nothing to do with my age," Hotaru said after accidentally pushed a plate onto the floor because she wasn't looking. "Please tell me that's cheap," she added guiltily while counting how many expensive plates she had broken since her rebirth. Fortunately, Michiru didn't get angry at all. Instead, she chuckled and gently examined Hotaru's hands. "I guess this means I have to worry about you always," she winked playfully and was glad that there's no wound at her daughter's hands. "And it's alright, that's a buy 1 get 1 free."

"Oh, thank you," Hotaru cleaned the broken pieces under Michiru's watchful eyes. After that, her mother told her to go to her room because it's almost past her bedtime. Hotaru obediently went to her bedroom, changed into pajamas, and brushed her teeth. Before turning her lamps off, she checked her school's stuffs in case she forgot her homework or something.

That's when she was lost in her thoughts. Juuban Elementary School was totally fun, compared to Mugen Academy from her past life. Especially the classmate part. There's no trace of bullying or other things Hotaru found in her current school, probably because their minds were still innocent. That's enough for her. But Hotaru thought half of the fun disappeared after her best friend was gone.

Chibiusa.

Her best friend in the world went back to the future where she belonged. Since then, Hotaru went to school without her. It's not like she couldn't or didn't want to go to school without her, heck Hotaru was thrilled to meet her new classmates everyday, talking about anime or manga, playing hide and seek, or other childish and peaceful things. She didn't lost contact with Chibiusa, either. There's still some news of her from Setsuna, or even a free trip to the future with Sailor Pluto.

Yet she'd often find that moment when Momo and Kyousuke wanted to be just the two of them, or when her friends were busy with their club activities, or when they went home with those who took the same path as theirs...Hotaru had no other things to do but staring at the empty seat beside her-

"Hotaru?" Michiru's melodious voice pulled her back to reality. The little girl turned her head at her door, unaware of her almost teary eyes. Her mama entered with a raised eyebrow, but concern plastered on her beautiful face. "What's wrong? I thought you've gone to sleep-are you crying?"

"Uh?" Hotaru didn't even realize that her voice cracked. "I...I..." She tried her best to hold her tears that came out of nowhere. Michiru was faster to take care of the situation. She fastened her pace and knelt in front of Hotaru, cupping her cheeks with her hands. She didn't say a word but offered her a comforting smile. The youngest senshi wanted to say 'I'm okay' but she couldn't. The image of an empty seat beside her haunted her-not just that, her lonely memories of Mugen Academy also appeared. So she uttered something that came up to her mind first.

"I...miss Chibiusa."

Michiru melted her aquamarine-colored eyes. She saw it coming far away before it happened. She knew how close her daughter and the future princess was. When Chibiusa went back, Michiru was quiet worried about Hotaru's schooldays. What if she's lonely? What if she lost her spirit because Chibiusa's gone? Fortunately, her fears didn't come true. Plus, they didn't lost contact thanks to Setsuna.

So why did she miss her?

"I...it's empty, I..."

Hotaru tried to explain. No, missing Chibiusa wasn't quiet right. The pink-haired princess would always be in all sailor senshi's hearts before and after she's born to this world. It's a private feeling. When she saw that empty seat, how she wanted someone to sit there, beside her, to stay with her until the very last school bell just like what Usagi and everyone always did.

Her mother knew best.

After being bullied for so long, Hotaru really, really wanted to have real best friends.

Michiru gently wrapped her arms around Hotaru, to pick her up into her arms then sat on her bed while rubbing her back in a calming manner. Hotaru buried her face into her mother's chest, not wanting to cry any louder. When her body relaxed for a bit, Michiru began to speak.

"You'll have one or more, sooner or later," Michiru consoled. "They might be different than Chibiusa, but they're worth to have. Searching for a best friend is no easy task, but you shouldn't give up because they'll be one of the most irreplaceable things you have."

"Like family?" Hotaru quietly asked, her eyes were quiet swollen. Michiru rested her forehead on Hotaru's and closed her eyes, "Like you, me, Haruka, and everyone else," she answered. Finally, Hotaru let out a small laugh, "Then it's like family."

"Well, isn't my darling so smart?" Michiru planted a kiss on her nose and tickled her a bit, making Hotaru laughed again. After having a tickle war for a while, the next thing Hotaru felt was the warm embrace of her blanket and the comfortable darkness as she drifted off to sleep.

"So this is Tokyo?"

The Tohsaka's heiress mumbled to herself as she stared at the moonless night of Tokyo. She's standing on the balcony of a majestic castle that's strangely built in Azabu Juuban. Unbeknownst to her, the castle itself had been a very hot topic between the citizens who wondered who the heck built such prestigious household.

The answer was simple: it belonged to the Einzbern Family. With a touch of their expert magecraft, the castle was finished just in one week.

"Nee-san?" Sakura Matou called out to her sister from inside, "What are you doing out there?" she asked and walked towards her.

Rin Tohsaka shrugged, "Nothing, just looking at Tokyo's scenery."

"It's my first time, too," Sakura mused, looking at the cozy building lights of Tokyo at night, "To think that we're going here together with everyone..."

"Unfortunately, we're not here for vacation," Rin pointed out. "You know what we're going to, right Sakura? I hope you're prepared for that."

"I'll try my best, Nee-san!" Sakura assured her, "I'll fight with you alongside Senpai, Rider, Saber-san, and everyone!"

Rin sighed in content as she crossed her arms, her worries for her little sister loosened a bit. "Well, that's for that. Why don't we prepare ourselves for our new school day tomorrow?"

"Oh right, even Illya-chan wants to attend school in Tokyo. I can't wait for it," Sakura giggled. Even in the middle of preparation for war, Rin's still thinking about school and studies. That's so her sister. And it made a certain angelic little girl jealous that she wanted to attend school herself. Right now the little girl must be asleep, too exhausted after preparing for her very first schoolday.

"It's a great sight, isn't it?" another person came out from the castle, it was Shirou Emiya. Sakura greeted her senpai while Rin waved back at him. They chatted about their preparations for school for a while then enjoyed the scenery of Tokyo at night in content together.

"...I won't let this place to be destroyed," suddenly, Shirou murmured. His eyes narrowed as if he's not looking at Tokyo, but other place instead. A horrid, agonizing place that was carved into his mind after a tragic event. Sakura and Rin didn't answer him, that's actually a sign of their agreement. "Not just Tokyo...Fuyuki...Japan...and the world. I'll do my best to protect them all."

"That's so you, Senpai," Sakura smiled with a blush, admiring the man in front of her. Rin fell silent, then she couldn't help herself but chuckled. "Well, you know what to do right, Shirou?"

"Yes," Shirou answered her, "What I must do...no, what we must do is win the Sixth Holy Grail War."

"Let's go, Setsuna-mama!" Hotaru impatiently called out her other mother who's still locking her car. They're in Juuban Elementary School's parking lot. Since Setsuna worked half-time as the school nurse they always came together in the morning. Not to mention they always came very early because Setsuna didn't have a 'late' word in her dictionary. It's not a problem for Hotaru, besides she loved to clean her class before their lessons voluntarily.

"Alright, I'm finished," Setsuna smiled and let Hotaru dragged her by hand. It's a joy to see how energetic her little firefly was. She just hoped that she wouldn't lose her cheerful self. Michiru had told her and Haruka about Hotaru's little problem yesterday. The time guardian couldn't help but feel sad for her daughter. If Hotaru missed Chibiusa, Setsuna would willingly let her come to Crystal Tokyo whenever she could. But if Hotaru wanted a new best friend who'd stay with her as much as Chibiusa would do, then she could do nothing but provide her support. Now if only-

"But Saaaaber!"

"How many times do I have to tell you, Illyasviel?"

Hotaru and Setsuna stopped in their track. Not so far from their car, there's an unusual sight in the school's parking lot. It's the first time there's a very sparkling and striking black Mercedes-Benz 300SL, something that turned both Setsuna and Haruka's mouth agape, if Haruka was there. Hotaru didn't quite understand about cars, but from it's appearance there's no doubt that the owner was a high-class aristocrat. As for the source of the voices, curiosity filled Hotaru's mind as she drew closer to the car and found two talking people-a young woman and a young girl.

Now that's what she called foreigners, attractive foreigners. Their skin was beautifully white and soft. The young woman has golden hair tied up in a bun, quite similar like Usagi's and Minako's but somehow it looked finely textured as if sprinkled with golden dust. In contrast to the young woman, the young girl had long silver hair as graceful as snow. If Chibiusa was there, she'd be frozen in awe.

"I said I don't like spinach! I don't like what I don't like!"

Euw, at the mention of that greenish culinary object that Michiru-mama often forced her to eat made Hotaru shiver. The young woman was holding a cute-decorated lunch box...with a little spinach on it.

"Shirou and Sakura made this for you. You should consider their efforts."

"I know~ I'll eat it all but the spinach-you know what, why don't you eat it?"

"That'll go against the purpose."

Those two were bickering over a lunch box in the morning? How strange. Still, that made them more interesting. Hotaru stared at the young silver-haired girl more clearly, it seemed like she's on her physical age and probably only an inch shorter than her. She's wearing a brown-colored uniform with a hat and red ribbon on it. It's strange, she never saw that girl before. A transfer student, perhaps?

"Spinach is good for your health, young lady."

Setsuna politely entered their conversation, seemingly interested at them. The foreigners turned their heads at her, and Hotaru must admit that the young woman was as charismatic as her father with the elegance of her mothers. Her shyness took over as she hid behind Setsuna.

That's when her purple eyes met with clear, crimson eyes.

"I beg your pardon, we must be quite noisy in the morning," the young woman apologized. "Illyasviel, go apologize too," she motioned the girl. "Are you a doctor?" instead of doing what the young woman said, the little girl curiously asked Setsuna who looked like a doctor with her white coat and mature appearance.

Setsuna smiled gently while the young woman scolded her again, "I am Setsuna Meioh, the nurse of this school," she introduced herself. "It's truly interesting to see new faces in this school. Is this young lady a new student? If there's something I can help with, fell free to tell."

"Do you know where class 6-E is? Shirou said that's my new class," the little girl asked again, her angelic face full of curiosity and excitement.

"That's my class!" throwing away her shyness, Hotaru jumped excitedly. All eyes went on her on an instant then her shyness went back again. "I...um..."

"This is Hotaru Tomoe, my daughter," Setsuna introduced her, pushing her daughter away from her gently. "Hotaru, go say hi."

"Hi," at least her voice was loud and clear. The silver-haired girl stared at her again, and all she could do was smile awkwardly. Gosh, since when did she become so shy?

The silver-haired girl returned her smile with her own. She gently lifted her skirt up and curtsied in a polite manner. "I am Illya, a soon to be student of your class," she winked playfully, "I guess I'll be in your care from now on!"

"We're late!" Usagi and Minako chorused while running in the corridor. As per usual, they're late. When they tried to skip some stairs, Usagi accidentally tripped and did Newton's Law of Motion before pulling Minako by her hair in reflexes. The two blondes fell with ungraceful manners onto the stairs-

"Whoa, there!"

A flash of red covered their sights before a loud crash was heard. They shut their eyes in the process. Strangely, they didn't feel the hard cold stairs that'd probably do a number to them. What they felt was a sensation of being covered in a hug by a man-huh?

"Senpai!"

"What's wrong, Shirou?"

Two girlish voices echoed in Usagi's ears. After she opened her eyes, she looked at the blushing and wide-smile Minako before turning towards their savior-a guy with auburn-red hair and golden-brown eyes.

Well, he's eye-catching, even Usagi who already had her soulmate blushed.

"Aino-san? Tsukino-san? Are you two late again?" their homeroom teacher appeared behind the red-haired guy above the stairs followed by two beautiful girls, one with purple hair and one with twin-tailed black hair. "A-are you okay?" the purple-haired girl stretched her hand to Usagi shyly. "Oh-I'm fine! Thank you," Usagi replied and gladly took her hand. Meanwhile, the twin-tailed girl easily picked the moonstruck Minako up to her feet. "Huh? Oh, te-heeh! Sorry!" Minako awkwardly giggled and rapped her head.

The savior guy got up and stood on his feet after cleaning some dust from his pants for a bit. "It's alright, just be careful next time," he smiled. Usagi stared at the three new lookers. They didn't wear Juuban High uniform, what they wore was a brown-colored uniform that had different design with hers. Were they-

"Since we're still taking a walk to class, I'll forgive you this time," their teacher sighed, "However, I expect you two to guide these new transfer students on their first day of school. Do I make myself clear?"

"Oh, er, yes sensei!" Usagi and Minako answered obediently. The three transfer students let out a muffled giggles, making them squeal in embarrassment. "Now, Matou-san, your class is over there. Your homeroom teacher is already waiting for you inside," their teacher explained to the purple-haired girl who nodded in response.

"Well then, I'll be taking my leave. See you later Nee-san, Senpai!" she waved her hand to the other transfer students then smiled and bowed to Usagi and Minako, "Nice to meet you too, Senpais!"

"Ssssssenpai?!" Usagi flushed and squealed in joy. The sight of her grown-up, genius and beautiful senpai version filled her imagination. Minako waved back and glanced at the class she'd take, so that girl's a first year. As for the other two-

"I'm Rin Tohsaka," the twin-tailed girl who wore a red cloak over her uniform bowed politely. "It's a pleasure to meet you. We'll be taking your class so please take care of the reckless guy over here."

"Tohsaka!" the guy frowned before clearing his throat then offered his new classmates a kind smile. "Nice to me you, my name is Shirou Emiya. We'll be in your care."

Hotaru's class was waiting for the new transfer student.

Originally, Illya wanted to go together with Hotaru but she needed to meet with the headmaster and her homeroom teacher first. The young woman, Saber (Hotaru and Setsuna were surprised that a beautiful woman like her had such a... masculine name) acted like Illya's personal bodyguard. Setsuna first thought that she's Illya's mother, albeit her young appearance-she spoke for herself. Illya excitedly bombarded Hotaru with questions regarding the school who let her be her guest.

After they dropped the two newcomers off the headmaster room, Hotaru curiously wanted to wait for them but Setsuna told her to go to her class. She could wait for Illya there. Hotaru made sure to make her class sparkling clean before Illya arrived. Her classmates entered the room one by one and she told them that they had got a new classmate, making everyone equally excited.

Hotaru took a seat, and glanced at the empty seat beside her. Actually, there're still more than three empty seats behind her, her class had the least amount of students. Where would Illya sit? Would she choose to seat there or-

"Alright, students! We've got a new friend in our class!" her teacher cut her thoughts, followed by a loud cheer of children. The teacher allowed the new student outside to open the door as Illya came in. Half of her classmates were struck in awe at her beautiful silver hair.

"Good day to you all," the girl politely did her curtsy like in the morning, "I am Illya, I shall make it Illyasviel von Einzbern for you to know. It's very nice to meet you," everyone awed at her introduction.

A German foreigner? Michiru-mama would be so pleased, Hotaru thought. "Now, Einzbern-san, where would you like to sit?"

Somehow, it became a very critical question for Hotaru. That girl could choose any other seat but the one beside her. Even some of her classmates became excited and wanted the angelic girl to sit near them. She knew it sounded selfish, but she wished someone would just seat beside her, to be her best friend-was that too much for a wish? If only someone or something would grant her wish-

-and the Einzbern wish-granting machine heard that, loud and clear.

"Can I sit beside Hotaru?" she requested, "She's my very first friend."

Hotaru's smile couldn't be wider.
