Fate/Grand Order (you can find it on Google Play or as a movie. It's called Fate/Grand Order: First Order) cross.

Warm amber eyes opened up when she felt the bed moving slightly. A small green creature crawled from where it had been napping on the pillow to lick her cheek.

"Mmm... where am I?"

"Ah! You're awake!"

The girl slowly lifted herself up to look around. She was in a room, the light was on and there were two men with her.

"How are you feeling? You seem to have been knocked out cold by the Spiritron particles when you went through the initial calibration phase," said a man wearing a lab coat.

"Where am I?"

"My room," said the other boy.

"Why am I in your room?" she asked, still dazed. She could feel Leon crawling onto her head, but didn't really notice it overly much. She was used to him by now.

The doctor looked rather sheepish at that.

"I couldn't exactly play hookie and leave a patient alone in the infirmary, so I carried you to my usual hiding place," he admitted. "But now that you're awake I can make sure there aren't any other adverse side effects. Most people aren't knocked out like you were during a simple calibration test."

She sat calmly on the bed, and let the doctor examine her.

"First off, do you remember your name?"

"Sora Sinclair," she replied after a moment. It wasn't quite right, but it seemed to fit well enough for her.

"Age?"

"Eighteen."

"Well I can obviously see you're female... what's your little lizard's name?"

"Leon...and he's a shape-changing chameleon."

"Shape-changing..." started the doctor.

"Chameleon?"

"He belongs to someone very precious to me. Someone who is irreplaceable. Except they had to go away for a long while, so they left me their partner to make sure I didn't get lonely or forget."

It was like an echo of a memory. Telling her not to forget. To never give up or let go of the past. To keep fighting and bring back her precious person.

Leon crawled into her hand and turned into a familiar green gun.

"That's why I came to Chaldeas. To bring my friend back. To bring all of them back."

"...I'm not sure that's possible. From the way you're reacting, I suspect your friend is..." started Dr. Roman.

There was a massive explosion. Considering the two males had been enjoying some hot coffee and snacks while she slept on the bed, they were entirely unprepared for it.

All the same, the three of them bolted to the main command center where the Chaldeas was rotating slowly above.

The boy went to the girl slowly dying from being pinned. The doctor ran to get the back-up generator going.

Sora looked up at the Chaldeas, with an odd look of serenity on her face.

"Soon. Soon it will begin and I can see them again. My precious friends..."

She hugged Leon tighter to her, and the chameleon licked her cheek. He missed his human partner too, and had only stayed because that man had told him to keep an eye on his foolish student.

The one child that could make a truthful claim of calling that man her father in every way that mattered.

"Owie... where am I now?"

Amber eyes opened to find a disaster. There were no people. The city was completely barren of all life.

It was horrifying.

"Awake, are we little lady?"

She almost yelped, realizing she was in the lap of a man with rather odd clothing and blue hair. But there was warmth in him...a familiar warmth that told her he could be trusted.

"Who... are you?"

"Hm... call me Caster. That is my role in this Grail War after all," he said with a cocky smirk.

She blushed, making Caster laugh a little more and grin at her.

"How long have I been out?"

"About an hour or so. At least that's around the time I found you. You're the first human Master I've seen in the past three days since this mess started," said Caster.

"What happened?"

"I don't know. A fire sprang out of nowhere, and without any explanation all the humans disappeared...including our Masters. Then Saber went nuts and restarted the Grail War. I'm the only one she hasn't corrupted that's still left."

"A fire..." said Sora, looking around.

Somehow, she knew what the cause of the fire was. Except she couldn't remember.

"By the way, little lady...what's your name?"

"My name? Call me Sora. This little one is Leon."

Leon crawled onto her hand and stared at Caster.

Caster was about to say something, but he sensed the presence of another Master...and a proper Servant.

"Think you can walk?"

She tried to get up, but her legs were still a bit wobbly. Caster grinned and without any warning at all he scooped her up in his arms.

It was faster than matching her pace, at any rate.

"Wow... you're really strong, Taiyo-san," said Sora.

"What did you call me?" asked Caster, baffled.

"Taiyo. Meaning 'sun'," she clarified.

"My name is Caster, not 'Taiyo'."

"But you feel as bright and warm like sunlight to me," said Sora smiling. She grinned when she realized that saying such a thing with an honest and straight face got Caster to blush. "And the way you used your magic was really cool!"

"It was just runes," said Caster embarrassed.

"Yeah, but I doubt I could do something like that," said Sora.

"Eh, it just takes a little practice," said Caster, scratching his cheek. "I bet I could get you casting like that in a few days, if you really put in the effort."

Something about this Master had him somewhat eager to please. It was like she was a breath of fresh air mixed with untainted innocence and a genuine personality that was hard to compete with. The kind of person that could make even hardened criminals turn over a new leaf just to see her smile at them.

As they went to find the other Master and Servant still active, Sora suddenly recognized one of them.

"Ah! It's Mash-san and Fujimaru-kun!"

"Friends of yours?" he asked. She nodded quickly. "Guess it wouldn't hurt to lend them a hand then."

He grinned and made his grand introduction.

A short while later...

"Sora-chan! I was worried you didn't make it when the drive activated," said Fujimaru.

"Who are you?" demanded the Director. Mash looked equally confused at her appearance.

She looked like any other Master applicant...except Mash had no recollection of seeing her.

Fujimaru looked surprised at their reactions, especially when Dr. Roman contacted them to talk to Caster.

"Thank goodness you're alright, Sora-chan. It seems all four of you made it to the Singularity safely!"

"Roman, you know this girl?" demanded the Director.

"Master Candidate 27, Sora Sinclair. She had an odd reaction to the calibration test and was still out cold when the first applicants were sent in to the coffins. She woke up just before the explosion happened," said Roman. Fujimaru nodded, because he had noticed her sleeping on his bed when he walked in.

The Director, however, was not convinced.

"The only potential Masters missing from the coffins was this fool who fell asleep during orientation. Everyone else was already waiting," she said, staring hard at Sora.

Something nudged Sora in her memories. She looked like she was getting a headache.

"You alright, little lady?" asked Caster with open concern.

"I'm fine. I just have a headache."

"Who are you really?" demanded the Director.

"I told you, my name is Sora Sinclair," she said, trying not to collapse. Her headache was really starting to hurt.

Fou jumped onto her shoulder and licked her cheek.

"Director, aren't you being a little harsh? She might have had a bad reaction to the Spiritron particles... there have been side effects before," said Roman, trying to calm the irate Magus down.

"Tch. Fine, but I know for a fact you aren't one of the Master candidates that were selected. I can't sense even the least bit of prana or od from you."

"Caster certainly seems to like her," commented Fujimaru.

"Well she's definitely a Master, I can tell you that much," said Caster blithely. "I can sense the command seals on her."

Sora found her hand taken by the Director, who examined it for the red markings. Only to find both her right and left hands completely unmarked.

"Is this some sort of joke? She doesn't have a single Command Seal on her."

"Ah. Director I can sense two Masters present as well. Both of them are standing right here," said Mash.

"You do know that sometimes the seals will manifest in odd places. I've heard them showing up on an arm before, or even on the back," said Caster.

"I am not stripping just to prove I have these Command Seals," said Sora without the slightest hint of hesitation.

"Hmph. I suppose that without a real explanation I can accept your claim as a Master Candidate...but know this, I am watching you. We still don't know who or what sabotaged the experiment," said the Director. "And it wouldn't be that hard to hypnotize that idiot Roman into believing your cover story."

"...I take great offense to that," said Roman.

As they were making their way to where the Grail...and consequently Saber...was, Caster decided to strike up a conversation with the little Master.

"You're not exactly with them, are you?" he asked quietly.

"Something bad happened. Something that would effect more than just humans. I was the only one that could be sent," said Sora. "I can't remember what it was though...just that I lost something really, really important so certain adjustments had to be made before I could be sent."

She cuddled Leon closely.

"I think it has something to do with why I have Leon and not his original partner. It was really sad though... so sad I thought I would break from it."

Caster was quiet. From the sound of things, someone had meddled in a way that caused her to lose people very precious to her, and they had hidden her memories to keep her sane. At least long enough to find out what the hell was going on and to hopefully start the process of fixing whatever was tampered with.

Even he knew that the fire that claimed the city and made the humans and their Masters vanish wasn't normal.

The little chameleon must be one of the things anchoring her to her duty while reminding her what she was fighting for.

He wouldn't mind being her Servant for real. She seemed like she'd be an adorable Master to follow and actually care about his opinions.

The Director went up to the roof to prepare herself for the fight ahead, while Mash and Fujimaru took the time to bond a little.

Caster, on the other hand? He decided to take advantage of the break to teach the unknown Master about runes since she had expressed an interest. It wasn't like he'd last very long once Saber was dealt with.

Sora was a very bright and attentive student... though apparently the last tutor she had liked to make sure she paid attention through bullets and explosives.

She was still very fond of the man though.

Caster was almost disappointed when the oldest member (not including him) declared it was time to go, having rested and finished her preparations.

Sora had memorized at least ten runes, six of which were good for quick casting and the other four could be used to amplify or make the first six even more effective. And he didn't get why the woman said that Sora wasn't a magus...she was able to use his runes (particularly the fire ones) just fine from what he saw!

Some time later

Something in her head was pounding. It was warning her that something terrible was happening and that this was only the beginning.

At least Caster was nice to her...if a bit flirtatious. He kept calling her 'little lady' and giving her these odd winks, but was actually quite the roguish gentleman. He seemed to be doing everything he could get her to blush around him, much to the annoyance of the Director.

And her back felt warm. Too warm to be normal around him. Like it was trying to tell her something.

As they were walking towards the entrance where the grail was, Caster slipped something around Sora's right wrist. It took her a moment to register that the silver bracelet he had been wearing was missing...and was now around her own wrist.

"Consider this a way to remember me when this is all over. Servants don't tend to stick around after the war is said and done, and you seem like you'd be an interesting little Master," he said with a flirtatious wink.

He seemed rather surprised by the gentle, if chaste kiss on the cheek for that.

"Consider that for luck then. Not that I think you'll need it," she said. Caster grinned at that, and hoped the bracelet survived so that the little lady could summon him as her Servant properly. Somehow he had the feeling this was only the start and that she'd need him sooner rather than later.

Though he also got the feeling he'd have to contend with others... what he hadn't told the stuffy woman was that he hadn't sensed the presence of one set of Command Seals.

He'd sensed no less than seven sets...one for each Servant Class normally available. Likely why the markings hadn't appeared on the back of the hand as they normally did...such a thing would require much more space, and was likely on her back instead.

It would be interesting to see what sort of shape those seals took. Each set was unique and tended to say a lot about the Magus' personality.

Sora stared at King Arthur...who was apparently a woman. Sensible to hide her gender then, considering during those times women had next to no rights and England certainly wouldn't have allowed a woman to take the throne. They barely tolerated Queen Elizabeth, and that was because the king had no male heirs at the time! Despite taking multiple wives!

"Saber... I have to ask why did you restart the Grail War? Surely you must have had a compelling reason to do so, despite the fact your Master had disappeared," said Sora, trying to reason with the Servant.

Something seemed to pass between Saber and Sora. A sort of strange kinship.

"Grand Order. Though you would know better than most why I was forced to restart the war and subjugate the other Servants, Guardian," acknowledged Saber.

Olga (the director) froze the moment said the words "Grand Order".

"How do you know about the Grand Order?" she demanded.

Saber looked at her with something close to pity.

"You have eyes, but do not see. You have ears, but do not listen," said Saber cryptically. "I cannot allow you past this point."

It would seem the time for talk was over. But Sora knew that Saber was trying to tell them something.

The way she called her "Guardian" resonated with her very soul, warning her that the memories were about to come back. And she would not like it when they did.

What was Grand Order, and why did she feel as though it had something to do with the fact she had no memory of entering the Chaldeas program? Why did she wake up in that room with no idea how she had gotten there, other than a sense that she needed to be there and that she had to follow Mash and the others to this point?

Why couldn't she remember?

And then it hit her when the battle was over and Caster had disappeared. She reached down to touch the odd crystal formation that had appeared where Saber had been...and the moment her skin came into contact with it she knew.

She remembered what had happened and why she was there. Why she had her memories temporarily suppressed until this point.

She nearly collapsed with a gasp.

"Sora-chan, what's wrong?" asked Fujimaru, openly alarmed.

The sound of slow clapping filled the air, and the second Sora saw the source her face contorted into a very angry scowl.

It was him.

Her hand grasped into a fist, unaware of the fact she still had that strange crystal in her hand. Something on her back seemed to flare with power, answering her inner desires. The crystal in her hand resonated with her soul and the markings on her back, creating a pathway that would take a few moments to fully set up and prepare itself for the summoning.

The man who caused all this, who created so much suffering barely took note of her. To be fair, she was partially hidden by Mash's shield.

The remnants of the crystal flew to him, giving him some power over time and space. But the majority of the magic inside of it had already been absorbed by her.

Then Mash moved the shield, just a little as she tried to keep Fujimaru from running after Olga who was floating to her death...and the man saw her finally.

"You. I killed you and that pathetic family. How are you here?" he said in fury.

Sora cast aside all doubts, eyes glowing amber along with the inner fires she possessed.

"My name is Tsuna Sawada, tenth generation boss and Neo Primo of the Vongola familigia. Sky Guardian and Keeper of the linear time-space axis of Gaia," said Sora, or rather Tsuna, as she drew out a ring she hadn't realized was around her neck and fitted it onto her right hand, along with another. A loud "Gao!" was heard as a lion appeared wreathed in Flames, and it took point next to her as the rings morphed into armor for her hands. "I am here to reclaim the balance that you so callously destroyed when you annihilated the proper flow of history."

"Balance, what balance?" sneered Leff.

"You were so concerned with the Magus side of things that you never thought to look into the underworld side. The Cosa Nostra has been keeping the balance of this world intact for well over a thousand years...and you completely destroyed it. So I was sent to bring it back."

"I killed you personally, you little wretch. How did you survive?"

E'la nostra ora incisa sull'anello.

Our hour was engraved on the ring.

"Time that has been etched into the Throne cannot be undone. Not by mortal hands. And regardless of whatever powers you have claimed, you are mortal," said Tsuna with conviction.

Leff was pissed, but at least he got to kill off the simpering twit called Olga of the Animasphere family.

Before Tsuna passed out, she did see one thing.

A familiar head of blue hair and red eyes catching her and holding her close in his arms. Except this time he seemed to be carrying a lance and wearing armor.

"I've got you, little lady."
