#2) Fate/stay night Crossover Fate/kaleid liner prisma Illya plot bunny attack~!

It all happened in one instant. Two existence met, contemplated and accepted each other. Both existence, within a span of the time it takes for time to pass, agreed to coexists with each other and returned to 'their' body. One body, previously hosting only one existence, was completely remade in the next instance to hold two souls that are one. A body that was once that of a regular high school teenager's reforged itself into the body of a soldier and then returned itself into a teen's again. Skin tanned and hair bleached pure white for a moment's moment before returning to their normal reddish hue. In a moment that has no numerical value, two existence came together as one. There was no flash of light nor sudden burst of power to indicate the metamorphosis, just a tiny, almost untracable sound of shattering glass in the void. Without anyone's but a certain vampire's notice, the process completed and stayed.

-Change in perspective-

Emiya Shirou paused for a moment in ladling soup to bowl that one of his guardian/ maid had handed him. He blinked once and then continue to finish the action of pouring soup into the bowl. His guardian, who was standing by his side trying to reach some dishes in a cabinet, noticed the slight paused and asked

"Is something wrong Shirou?"

"...Nothing's wrong Sella. Here let me get that for you." Shirou smiled casually and puts down the bowl of soup down to reach for the plates that his guardian, Sella, couldn't reach. Handing the discs to her, he begins bringing the food that he had prepared for dinner out to the table. The white haired guardian follows shortly afterwards with the plates, bowls and eating utensils.

"Illya! Liz! The food's ready! Come and eat before it cools down!" Sella calls out to the living room where the second guardian, Liz, and their second charge, Illya, lie on the couch to watch an anime. Liz perked up and crawled out of the couch immediately after hearing the word food while Illya stayed to continue watching. Seeing her younger charge acting like this made Sella moans aloud about the taint of the world clutching at Illya's innocence.

Shirou chuckles at Sella's reaction and goes over to Illya. Contrary to his belief that his sister was being deeply enthralled into her anime, the little girl was paying little to no attention at all to her show and was more or less just staring into the direction of the television. A part of Shirou was pleasantly surprised that he was wrong while another part quickly did an analysis of the expression on his sister's face. 'She's contemplating upon whether or not she should be doing something' he notes mentally to keep an eye on her as he reaches out to tap her on the shoulder. She didn't respond to it or his second tap. He decided to then give her a shake on the shoulder which seemed to have brought her thoughts back to reality.

"Huh? Wha?" She confusedly looks around and sees him holding her shoulder. She blushes lightly and looks at him. "Is there something wrong onii-chan?"

"It's dinner time Illya." He smiles sweetly at her as he turns off the television. "Liz and Sella are waiting."

"Ah, right." The middle school girl jumps to her feet and quickly runs to the dinner table to join the rest of her housemates.

As everyone sat down and got comfortable, they simultaneously clap their hands together as one and said "itadakimasu". They then reached out their own chopsticks and started eating the food made by the eldest Emiya son. Liz quickly demolishes her first bowl of food and hands it to Shirou for a refill before he even got in a second bite of his own. Sella happily eats the well prepared dinner while pushing back the various thoughts of how inferior her cooking is compared to her charge. Illya slowly and distractedly worked to finish her bowl which causes Shirou to worry if there might've been something wrong with her health. A part of him quickly supplied that there is nothing noticeably wrong with the girl's physical condition but worry he still did.

Halfway into dinner, Illya starts glancing at the clock every few minutes. She picks up the pace of her eating and finishes as Liz got her fifth bowl. She then excuses herself saying that she wants to go to bed early. Shirou didn't buy it but lets any thought of what to do to after dinner. While clearing the dishes from the table, he reinforces his ear enough to listen in on Illya. As he suspected, the girl was pacing around in her room to stave off time before she has to go to wherever had her distracted for so long. He does not remember the cause of this but he has a slight suspicion that it might have to do with what knocked him out at the bath yesterday (he's sure as heck that it wasn't a rock).

As he finishes washing the dishes, he hears Illya finally making her move. The sound of the window sill opening and closing with a distinct sound of shuffling cloth in between was more than enough to tell him what his sister was planning. Drying his hands and excusing himself to his room as well, Shirou left his two guardians/ maids to their own business. He quickly and silently walks out to his room and passes it to reach his sister's. He knocks twice out of manners more than cluelessness and walks in as his sister jumps off the window ledge... in a magical girl costume.

'Huh... when'd that happen?' For the first time in the hour of the acceptance, Emiya Shirou stopped his mental multitasking and stared. The part of him that was the 'No name hero' recovered first and jumps out of the bedroom's window to follow his sister. It took him a minute to catch up to her and another to maintain a far enough distance to (hopefully) keep out of her sensing range while still being able to see her with reinforced eyes.

Illya stopped at an open field in an academy that he recognized as her school. Decisively walking to a certain location, she met with a familiar and yet unfamilair Tohsaka Rin. He'd only managed to hide in the shadow of a nearby building before Illya held out her magical wand and enacted a ritual. Both Rin and Illya disappeared within the ritual circle. This was a shocker. From what he saw, his sister had just completed a high level transition ritual to god knows where without much, if any, prior preparations.

'Did she notice me following her?... No, she gave no outward signs that she has noticed anything following her. But then what is she planning on doing here?' The no name hero pondered on his sister's plan while the high school boy walks to the spot that he last saw the two girls. Careful examination shown nothing suspicious or out of place, not even a mark. He was startled out of his thoughts when he heard two pairs of footsteps coming up from behind him. Before he could do anything to hide himself, the owner of the footsteps spots him.

"Who are you and what are you doing here?" Was the question of one of the two behind him. It was high pitched and commanding, probably the leader of the two. The no name hero/highschooler turned around with a disarming smile on his face. The no named hero recognized his old friend Luvia standing dominantly with her hands folded under her chest and back straight up. She has on a strange combination of a blue dress and combat boots underneath. Besides her was a girl clad in a questionable purple and black leotard/ magical girl dress. The girl looks to be about Illya's age and is holding a wand that was conceptually made like Kaleidostick Ruby. The no name hero took note that the girl widened her eyes in recognition while the highschooler judges that he doesn't recognize the girl. Before anything else could be read though, the girl closed off her emotions and puts on a well worn mask of indifference.

Quickly grasping onto something, the no name hero took in all the facts that he had gathered and made something up. Rin and Luvia are present with potentially two kaleidostick, if the magical girl dresses are anything to go by, so that implies that Zeltrech is involved somehow. The four girls met up in this exact spot so it must have some importance. Maybe a test or punishment of some sort that Zeltrech has sent them on? Mentioning the name Zeltrech might yield further results.

"Hello Edefelt-sama, I have come here under the orders of Zeltrech-sama to look after yours and Tohsaka-sama's task." He lied through the skin of his teeth with a smile that has been trained for years. Luvia pales and pulls back into a slightly guarded pose. He gathered that she probably messed up her mission somehow. It was probably not that far off of a guess, seeing as how her relationship with Rin is... explosive.

[Hello, I am kaleidostick Saphire, may I ask for your identity as well as reference from Grand Marshal Zeltrech?] The magical stick asks politely as it refers to Shirou in place of the now slightly less confident Luvia.

"Certainly, you may call me Shirou and here's the letter that Zeltrech-sama has sent me a while ago." He reaches into his jacket to trace a letter that was written by Zeltrech for a rather vague task in his past "life" and handed it to Luvia who shakily accepts the parchment. She only pales more and her shaking became more prominent. Shirou grins inwardly when the curly haired blonde declares that it was in Zeltrech's handwriting and gave the letter back.

"Can I ask for a status report? Zeltrech-sama sent me here rather urgently and I'm at a lost as to what I'm supposed to be monitoring."

[Ah yes, the mission that was assigned to us by Grand Marshal Zeltrech is to collect the stray class cards from the remnants of the disbanded holy grail in Fuyuki. Our coordinator, Lord El-Melloi II, sent Luviagelita-sama and Rin-sama to partake in this mission. However, due to circumstances that you will be briefed of later, Miyu-sama here and another wielding my sister, Kaleidostick Ruby, is now in charge of the mission.] Kaleidostick Sapphire momentarily paused and a clock flashed on its hexigonal star. [In fact, we should hurry. The mission time is five minutes ago and we are late. Please gather up so that Miyu-sama can open a gate to the mirror world.]

Neither the no name hero nor his high school equivalent could have process anything of what was said by the magical stick. Its wielder stepped towards him with Luvia following behind before raising the stick high in the air. A large magical circle, similar to Ilya's appeared underneath his feet and Saphire's voice echoed

[Two meter radius, Mirror Road formation. Opening path to the other world.]

The world was flipped and reversed before flipping once more. As the no named hero immediately steadied himself, a chill ran through his spine. The scent of raw blood filled his nose and he immediately snapped his neck towards the direction of the scent. His eyes widened. Right there, high in the sky, was a Pegasus rushing at extreme speed towards the ground while dodging magical bullets being shot at it. It's rider, though having a different, more blackened outfit, was definitely the first servant Saber took out in his Holy Grail War, Rider.

"A Noble Phantasm!?" Luvia whispers in awed horror while staring at the steed.

[Miyu-sama!] "Sapphire, class card Lancer: Include!" Besides him, the magical girl drew out a card from her thigh holder and puts it in front of Sapphire. Another rush of magic bursts from the stick and a red barbed lance took place of it. Shirou took his eyes off of the pure white Pegasus and it's darkened rider to glance in bafflement at yet another miracle happening right next to him. The magical girl pulls back her arm and aimed at the Pegasus rider before throwing the lance and screams "GAE BOLG!"

The lance disappeared as it left her hand and reappeared in the place of Rider's heart. Or at least, it was supposed to. The pegasus, in it's rights as a Divine Beast, pulled off a miracle only it can. Turning it's very body into pure power and light, it timed the moment when the Laws of Casualty enacted itself upon its rider and twisted. Sacrificing itself for it's rider, the beast took the heart rendering stab. Before it's physical body returned however, it looked at the one who has caused its rider to summon it in the first place. The girl who has cause it and its rider to feel this unimaginable rage. And the winged horse charged.

Miyu and Luvia widened their eyes at the impossibility that happened before them while Shirou followed the steed's path of attack and almost gave in to a heart attack. The pure force of the divine beast was being aimed at his most beloved sister, who was trying her very best to stave off her foe with beams of raw magical energy. Without any thoughts or doubt, the no name hero clocked his trigger and let loose the might of his own magic against the one who wants to harm his beloved sibling.

"Trace On!" A familiar black dao sword with red vein-like hexagonal patterns appeared into the world and landed into his open palm. "Trace: OVEREDGE!" The black sword bloomed in shape and size. What was once a pristine sword of pure black metal burst into a winged shaped contraption easily thrice its original height and much deadlier than its original shape.

Swinging his reinforced arms, he threw the Broken Phantasm straight into the general direction of his sister and watched as the sword's ability did its magic as he traced a pure white dao into his palm. With the momentum from his throw gathered together with the force of attraction from it's ability, the black Broken Phantasm made a sharp turn and slammed into the path of the Pegasus.

Of course, he didn't expect his high B-rank attack to do much, just merely enough to slow down the target. And slowed the target it did. The beast collided with the blade and the winged dao stalled the creature of pure energy for a wide enough margin of a moment for Shirou to take a protective stance in front of his beloved sister.

As the black dao finally bursts into a hundred sharp feathers and the beast continued its charge, Shirou, with both his minds overworking as one to protect Illya, raises his hand and summon the strongest shield in his Reality Marble "RHO AIAS!"

A seven petaled iridescent flower blooms from his outstretched hand and crashes with the phantasmal being's rush. The impact easily crushes two petals and quickly works on the third and fourth before slowing down at five and six and finally coming to a full stop at the the seventh.

As the white beast disappears back to where it came from, its rider jumps off it with weapons pulled back and ready to strike. Shirou, who had already dropped to his knees from the recoil of Rho Aias, defiantly glares at the black specter with resolute eyes.

"...Trace: OVEREDGE!" Using whatever momentary strength he has left within his beaten body, he raises his remaining weapon into the specter's path. Of course, the black spirit had enough common sense to parry the attack but it did nothing about the sword's ability.

SHCH! SHCH! SHCH! SHCH! SHCH!

A barrage of black steel feathers slams into the spirit's unprotected back and nails it down to the ground, just in front of the kneeling hero.

"..." Finally getting a good look at the downed and snarling spirit, Shirou frowns deeply. As he had suspected, the spirit really is the Rider that he knew or rather, another partial incarnation from the throne of heroes. Unlike the one he knew however, this one is corrupted beyond saving and is still struggling to attack. The same and yet so different, Shirou frowns as he struggles to his feet and raises his white feathered sword.

"...This is not how you should be, please return to the throne of heroes as your true self..." With a sad frown, he lowers his blade and watches it decapitate someone who he had once called ally. He gave a brief moment of silence as the specter dissolves into black mist and another before dissolving his own weapons. Straightening his slightly hunched back, he turns around towards his two protectee and smiles charmingly.

"Illya, it's past your bedtime now. As a punishment for sneaking out in the middle of the night, no desert for a week."

"Eh? Onii-chan? Wha-? Wait, no desert? WHA-?!" Illya adorably stutters within her pink dress and Shirou couldn't help but make his charming smile more genuine. He's so glad that he's managed to keep his family safe.

Challenge to put in the story!

*After living a life as a hero, our no name hero accepted death with open arms as he is unjustifiably trialed and put on death row by someone he saved. Though he accepted death without complaints, he still had some regrets. The main one being that he couldn't have been there for the ones he loved/ ones he considers family and will never be able to again.

*Make a completely new route for the no name hero that encompasses parts of Fate, UBW and Heaven's Feel. The text from above has already hint at the grail having something to do with the transfer, made Rider an ally, Illya being his sister and Rin (and by some default, Shirou) knowing more about Kaleidoscope than most others.

*For comedy relieve, make Shirou trace Ruby and see what happens. He already knows the structure of the tool and is fully capable of making a slightly degraded version completed with newer and quirkier attitude, completely hellbent on making fourth wall breaking one liners. Magical Bro: Shirou has never been done before, wink wink nudge nudge.

*Instead of Excaliburing the ever loving crap out of everyone, try to make some innovative ideas for the way Shirou can fight besides the usual: Kanshou and Byakuga - Fatal injury - Glare down and monologue - More Kanshou and Byakuga- Random noble phantasm to buy time/word count (sometimes optional) - EXCALIBUR!

*Have fun writing the story.
