Chapter 10 - Next Card, Please (L)

...

The next day once again progressed as normal. Illya and I woke up cuddling together, then the two of us ate breakfast with Sella and Liz. Since it was Sunday, we didn't have school (thank God), so Illya and I opted to just hang out at home.

Or rather, that WAS the plan, until one of her friends texted her something. Illya ended up running over to help her out with something, leaving me by my lonesome. Again.

'Oh well.', I thought to myself as I relaxed on the couch. A knock on the front door interrupted my peace. Sensing it was Miyu again, I shouted, "Come on in, Miyu!", once more. Coming inside- slipping off her shoes in the process-, she enters the living room only to be greeted by me. "Hey."

"Hey." She says back. Her outfit is different, too. She's wearing a long sleeved, grey, button up shirt tucked into brown shorts, which- combined with her thigh high socks- really shows off her thighs. She also has a silver butterfly hair clip on the left side of her bangs. She fidgets a bit. I guess she's still a bit awkward about the dating thing, huh? "I, uh... left my plushie in your room last night."

"I noticed that earlier." I say, remembering that Illya was surprised to see another plush next to hers this morning. I stand up and beckon with my hand, "C'mon, let's get it."

Miyu nods and quietly follows me upstairs. Entering my room, I grab the stuffed cat plushie and hand it to her. Miyu takes it from me, a small smile on her face. I can't help but vocalize that fact, saying, "You're way too cute, Miyu."

She jolts, before blushing brightly.

"Though I'm surprised you didn't come back and get it." I say, a bit thankful she didn't. Illya practically jumped me right after she left and we had sex for quite a while. Also, I realized that the other soul inside of her is aware as it reached out towards me while we were fucking. I gave it the equivalent of a reassuring headpat before it retreated, seeming satisfied. I still have many questions about that, but I'll save it for another time. Maybe after this Class Card shit is done.

"A-Actually... I did..." Miyu admits, her face a hundred times redder.

"Oh... So you saw...?"

"Yes."

The both of us avert our gazes from one another, both a bit embarrassed about it all. I shouldn't have just relied on the noise-cancelling shit and instead locked my damn door.

"Yeah, well... Illya and I have been... physical for a bit now, but after I helped you both the other night with Saber, both of us realized how important we are to one another and we... had sex." I say, simply. "And last night she was a little excited, plus Sella and Liz were headed to bed and I made a noise-canceling Bounded Field, so we went with it." I awkwardly scratch my head. "I guess I shoulda locked the door, huh?"

Miyu's lips curve up slightly, making a small smile, before looking nervous once more, clasping her hands together. Does she do that when she's nervous? "I... I'm sorry for watching the two of you." She says.

I smile. "It's fine. Like I said, I shoulda locked the door. Plus... I'm your boyfriend too, so you shouldn't get embarrassed about this kinda stuff."

"But I... I watched the two of you for a few minutes..." Miyu admits, shyly.

Smiling, I feel the need to tease arise. "Oh? Did you like the show?"

"O-Onii-chan!" She shouts as she whips her head towards me, clearly super embarrassed.

I let out a chuckle at her crimson face. "It's nothin' to be ashamed of, Miyu."

"You say that, but... I enjoyed watching you two..." She admits, fidgeting with her clasped hands, the stuffed toy still in between them. "I... I imagined myself in Illya's position. Kissing you and doing... other things with you."

I blink, before I pat my second girlfriend on her head. "It's fine to have those thoughts, Miyu. Besides, we'd just started dating just before that, it's fine to be a little jealous."

"B-But I...!" She stops herself midway as I pull back my hand. "But I... REALLY enjoyed it..."

Really enjoyed it? What does...?

"Miyu?" I ask.

"Y-Yes...?"

"Did you perchance... end up touching yourself?" I ask, a touch theatrically.

Miyu jolts, her body clearly being quite honest. "...Y-Yes."

"Oh? And where did I you touch, exactly?" I ask, opting on teasing the cute girl.

"My... vagina..." I blink at the scientific terminology. "I... put my fingers inside of it and... used them to do the same thing you were doing to Illya, but to myself."

"Ah, you're more familiar with the official terms of stuff and not the slang." I say, causing her golden eyes to blink in confusion. "Alrighty then! Let 'ol Shirou teach ya."

Despite her embarrassment, Miyu cracks a small smile from my words.

"A common slang for vagina is pussy, and what you were doing was fingering it." I say, simply.

"Fingering...?" She asks, slowly.

I nod. "When doing that kinda stuff, women also might grab onto their tits- breasts- and rub them."

Miyu blinks. "I... I did the same. I grabbed onto my shirt and..."

I let out a hum. "Good, you get it. You really are a fast learner."

Miyu smiles a bit, before looking shy again. "Say, um... Do you think we could... kiss, Onii-chan?"

I smile at her shy words, before reaching down and cupping her cheek, pushing her bangs to behind her ear. "You're so fucking cute, Miyu."

Before she can utter any words, I connect our lips.

Miyu and I's tongues tangle with one another. It's clear she hasn't done this before as she still is acting quite reserved and stiff, just like Illya was at first. But Miyu, being a quick learner, wraps her arms around my neck as her kissing suddenly increased in ability. Huh, school, arcade games, and kissing- what ISN'T this girl good at?

"Haah... Haah... Haah..." Miyu pants for air as we part, her golden eyes boreing into mine, a small trail of saliva connecting our mouths. I smile at her flushed face, her eyes filled with love and lust, clearly wanting more. Well, who am I to turn a girl as beautiful as her down?

smack smooch slurp shlurp

We make out again, her ability increased further, to the point that I'm not sure if Illya is the better kisser anymore. Miyu presses her body against mine, instinctually wrapping her leg around mine, grinding her hips against said leg.

We kiss for longer and longer, before we part, both of us breathless again.

"Onii..." She breathes. "I... never knew... kissing was..."

"Yeah... It's pretty... nice, huh...?" I ask, also panting slightly.

Miyu looks down, before blinking in surprise. Looking down, I notice her leg's still wrapped around mine, but more importantly, it seems I've gotten hard. My pants have a significant bulge right at the crotch. Not hard to figure out what that is, huh?

"It's... You're..." Miyu tries to speak, her golden eyes widened by quite a bit, clearly quite interested in this development.

"Yeah. It seems you got me a bit excited." I say in a low voice.

"I... can I...?" She asks. Knowing what she wants, I nod, reaching over and locking the door.

Sitting down on the bed, I move to pull down my pants to let her see it, but to my surprise, Miyu takes the initiative- likely spurned on by instinct and lust- pulling down my pants and underwear. She lets out a soft gasp at the sight of my member, standing tall and proud.

"I... They can get this big...?" She asks, eyes transfixed on the monstrous thing before her. "Does... Does it hurt?"

"Not at all." I say. "I'm just excited after that kiss."

Miyu, having set the plush toy to the side, curiously reaches up and touches a finger to the head of my dick. It twitches, causing her to reel back a bit, before wrapping her hand around it. "This... was inside Illya..." She says, still in a trance. She marvels at the thing in front of her, before she grabs it with her other hand as well. I let out a small gasp at her touch. "Ah! Did I-?"

"No." I say, holding up a hand to placate her frantic question. "Your hands just feel really good."

She blushes harder at that. "If... If I do this..." She says, as she moves hand hands down the shaft. "Th-Then it'll feel good..." She moves them back up. "And eventually, you'll have an orgasm and release semen..."

I nod. "Yes. I'll eventually cum and shoot out cum."

"Eh? You said 'cum' twice..." Miyu states, confused as she continues to stroke my dick.

"Cum is a slang for semen. TO cum is to climax- or orgasm." I explain.

"I see." She says, soaking the info in as she continues to move her hands. Up. Down. Up. Down. That's how her smooth hands move across my dick.

"The head of the dick- the pink part- is also more sensitive than the others. It's got more nerves in it, I believe, so it feels better to the touch." I instruct.

Miyu, quickly picking things up as usual, uses the fingers on her left hand to rub the head of my dick, as well as just under it, while her right continues to pump the shaft. Up. Down. Up. Down. She continues to rub and stroke my cock with her soft hands- which may be softer than Illya's. I wonder if she uses a different kinda soap or something. Her skills rapidly increase as she soon is jerking me off like a pro. I lean back, using my elbows to prop myself up as I enjoy the sensation.

She pauses her right hand to focus her left as it rubs all around the head, before going right back to moving both in tandem.

Pressure builds.

"W-When men cum, sometimes it shoots out quite far." I warn. "And I'm getting pretty close to climax, Miyu."

She nods, still enraptured by my cock as she rubs it more fervently, a small, happy, and determined smile on her face. She rubs faster and faster, her newfound ability not wavering in the slightest. The pressure builds faster.

"Miyu, I'm gonna...!"

As I say that, she moves her left hand over my dick, placing the palm against the top while her fingers still touch the head, all while her tight continues to move up and down. Up and down. More and more the pressure builds until-

spuurt spurt spuuuuurt

Miyu's left hand twitches a bit as it blocks the white substance from shooting out from my dick, causing it to fall downward, onto said dick. Her golden eyes sparkle with fascination at the turn of events. "Did... my hands feel good?" She asks, a bit shyly.

"Very good." I smile, causing the girl to preen.

Miyu takes her hand from my dick, examining the cum on her palm. "This is... semen...? No... cum?"

I smile at her curious gaze. "The first time we did this, Illya ate it."

Miyu looks at me suspiciously.

I smile at her dubious gaze. "I'm not lying. She loves to eat the stuff, for some reason." Maybe it's due to the mana transfer stuff, or maybe she just likes the taste.

The blackette still seems skeptical, but reluctantly licks some of the white cream with her tongue. She pauses, examining the flavor, before swallowing. "It's... salty, but... not in a bad way... And it's... almost like the taste makes you want more..." Sure enough, Miyu licks the rest off her her palm before swallowing it.

Just like with Illya, I watch in surprise as Miyu scoops up all the cum that fell onto my cock, before greedily slurping it up.

slurp shlurp slurrrrp swallow

After it's all gone, she stares at her hands mutely, before her face goes full on atomic. "I can't believe I just did that."

"Hey, it's fine. Like I said, Illya ate it all up to. Does it every time, as a matter of fact." I reassure her.

"No, I mean..."

"You can't believe you just jerked me off." I realize. She nods, embarrassed as she averts her gaze from mine. "I'll admit, it was sudden, but I'd say you got a touch desensitized to it after seeing Illya and I fucking."

"Perhaps you're right." She says.

"You know... turnabout is fair play." I smile.

"Turnabout?" Miyu asks, blinking in confusion.

"You made me cum, so I should make you cum in return." I say, bringing another vibrant blush to her face. "I mean, if that's okay with you." I correct quickly, not wanting to push the girl too far.

"Th-That... I su-suppose I wouldn't mind..." She says, shyly.

I motion my hand for her to stand up. Doing the same, I bend down and unbuckle her belt, as I slide her shorts down her legs, revealing simple, white panties. Her face is somehow redder than ever. It only gets redder when I pull them down as well, revealing her cute little pussy- clean shaven, too. Smiling, I get up and sit back on the bed. Spreading my legs, I pat the space between them.

Shyly, Miyu sits in between my legs. I lean forward, my chest against her back as I trace a finger across her slit, getting a cute moan out from her mouth. I rub it up and down a few times, before using my left hand to unbutton her shirt. By the time it's unbuttoned, my right hand has moved, instead using the fingers to spread her pussy apart. I lift up her matching white bra and cup my left hand on her small breast.

"This is what you did to your boob last night, isn't it?" I ask next to her ear.

"Mhmm." She hums in affirmative.

"And I believe you said that you did this as well." I say, the fingers of my right hand snaking their way into her virgin pussy.

"Gah...!" She lets out a gasp as two of my fingers enter her.

I smile, before whispering into her ear. "You're so cute, Miyu." The girl shudders at my words, before doing so again when I kiss the nape of her neck.

shlick shlick shlick

The fingers of my right hand and her pussy make wet noises while my left rubs her petite boob and my mouth peppers slow but repeated kisses on her neck.

"Anh... Mmm..." Miyu moans at the sensations overwhelming her small body. My left hand moves, now rubbing her hard nipple in between the thumb and index finger. My right hand still has fingers going in and out of her while the thumb takes a different approach, rubbing her clit.

My new girlfriend's body trembles as she continually lets out sexy moans from my unrelenting assault. I pick up my pace at all three spots, increasing her moaning and causing her walls to tighten a bit. Her breathing picks up.

"Are you gonna cum, Miyu?" I whisper in her ear.

"Y-Yesh..." She manages out, her words slurred a bit. "Onii-chyan... I'm gonna...!"

"Then cum, Miyu. Cum, you sexy little voyeur. Cum." I whisper huskily into her ear.

"Onii...! Onii-chan!"

squiiiiiirt!

Miyu's pussy tightens around my fingers as her entire body trembles from pleasure. Her scream is intentionally held back by her gritting her teeth together. After a few moments of spasming, she flops back against my chest, breathing heavily.

"How did that feel?" I ask.

"Amazing..." Miyu breathes out. "It felt good when I... but not this good..."

I smile. "I'm glad." I say. It truly is a sight to behold- having a nearly naked, petite girl leaning against you, breathless and happy as can be- evident by the smile on her face.

pop!

I pull my fingers out from her cunt, causing her to shudder again. Her eyes widen quite a bit when I begin to clean her juices off of my fingers with my tongue. She can only stare as I suck my fingers clean. I smirk, "Tasty."

Miyu cutely pouts, furrowing her brow at me, but eventually giving up in favor of smiling. Cupping her cheek with my still wet hand, I pull her face to mine.

smooch smack slurp shlurp

Our tongues wrestle with each other once more as we share a kiss, one with less energy than before. We part after a bit, still breathing a bit heavier than normal.

Miyu beams a bright smile at me. "I... I love you, Onii-chan."

I'm... surprised she went and said it. "You... really?" I ask. "We've haven't even been dating for a day."

"I know... It's just... You make me happy, Shirou." She says, still smiling brightly. "Onii-san always did what he could to make me happy, and I always enjoyed just spending time with him, but... for some reason, I feel a bit happier when I'm with you. Just spending time together."

I blink, shocked at the admission. I smile. "Maybe it's 'cause you're hanging out with me as my girlfriend instead of as my sister." Miyu blinks, mulling over that info. "Still, I feel the same. I'm far happier just spending time with you and Illya than I expected. I never thought I could enjoy just being around someone, never mind two someones, but I do... I love you too, Miyu."

She smiles even brighter, defying all logic. Unable to resist, I pull her into a tight, loving hug. We'd find ourselves remaining there, half naked, for quite a while. Just holding each other.

"Honestly! How does Tatsuko-chan even GET in these situations?!" Illyasviel von Einzbern finds herself yelling in frustration as she walks home from near one of her friends' houses. "I mean, where did she even manage to get a hockey stick and firecrackers?"

Despite sounding upset, she really isn't. Tatsuko is just that kinda girl- one who does crazy shit sometimes. Everyone who hangs around her is very aware of that fact. Smirking at the thought of her rambunctious friend, she enters her house, slipping off her shoes and saying, "I'm home!" With a quick glance, she notices that no one appears to be home. Curious, she goes upstairs to hear some chatter.

"What are you two doing?" Illya asks, entering her brother's room to find him and Miyu playing video games.

"I got Miyu to play Mortal Kombat." He explains, gesturing to the tv, where one of his favorite video games is on the screen. After telling the truth about his powers, he went and made a bunch of video games and stuff that haven't been released yet- this game being one of them.

"It's a nasty game, but is admittedly enjoyable." Miyu adds. Illya idly notes that she's wearing a cute outfit.

'Damn, that outfit really shows off her thighs.'

'Yeah, they- huh?! What was that thought just now?' Illya thinks to herself, surprised by the stray thought.

"You okay, Illya?" Shirou asks, furrowing his brows.

"Yeah, I'm fine." The albino girl says, waving off his concern.

"Well, you wanna play too?" He asks, earning a happy nod from the German girl as she sits on the other side of her brother. Illya also notices that the both of them seem incredibly relaxed for some reason.

'How much you wanna bet they went down on each other?'

Illya jolts, another strange thought entering her mind. 'Th-There's no way Onii-chan and Miyu would do something like that! They just starting dating yesterday.'

'Oh? You and Onii-chan went right at it after she left. Plus, she left that plushie of hers. Maybe she came back for it and saw you two, then wanted to try some things~'

'N-No way!' Illya argues with the stray thoughts, which seemed to have purred the words out at the end. 'Miyu's not that forward!'

'But she loved her Onii-san quite a bit, and now she loves Onii-chan. Who's to say those feelings haven't combined together or something?'

'B-But...'

'Plus, Miyu's clueless about a lot of common stuff, but eager to learn. Who's to say she wouldn't be eager to learn about naughty stuff too?'

Illya's face heats up and remains that way until Miyu left their house that evening. No matter what the trio did together, Illya never managed to calm down. Speaking of, as she left, Miyu kissed Shirou. A pang of jealousy went through Illya, but it quickly went away by another stray thought.

'You oughta kiss her too.'

Illya jolts at the voice's return. 'K-K-Kiss Miyu?!'

'Why not? I bet her lips are soft and all. Plus look at how cute she is, being all shy when kissing Onii-chan... Ah. She's leaving... Damn, those shorts make her ass look nice.'

'Uwaaah! Stop it!' The albino girl whines, mentally.

'Hey, go over to Onii-chan and...'

'SHUT IT!' Illya practically yells in her mind.

"Onii-chan!"

Shirou blinks, turning to look at his sister surprised. "Yeah?"

Illya walks up to her brother, feeling her face heat up. "Who's lips feel better?! Mine or Miyu's?!"

"...You look really serious, Illya." He says, leaning back a bit from her sudden closeness. "But if I had to choose, it'd be you. You use that lip stuff Sella bought you, but I don't think Miyu uses that kinda stuff. It makes your lips really soft."

Illya's face heats up again, as she feels ecstatic from her brother's honest words.

"But you shouldn't be worried about that kinda thing. I love the both of ya, I don't want any arguing or competition or anything like that. Okay?" He says, sternly.

'Smooth...'

Illya barely registers the voice, which sounds quite impressed, instead opting to rush forward and embrace her brother.

Shirou chuckles. "Geez, you're so greedy." He jokes, bending down and beginning to make out with the small girl. As they part, Illya decides she doesn't want this to end- ever.

'Hmm...'

She doesn't notice the voice hum in what sounds like jealousy, opting to focus on her happiness.

What happiness and relaxation the rest of the day brought was soiled by Rin putting a letter in the mailbox- and running off after ringing the doorbell like a child- saying that the next card showed up. I would ask why she didn't just text us, but then I remembered how Magi and technology are.

Oil and fucking water...

That aside, Illya and I stayed up until midnight, when we and Ruby all left together.

"Where did Rin say it was? The forest?" I ask, running towards the forest with my sister on my back.

"That's what the note said." Illya confirms, holding into my back.

"That dumb woman. Couldn't she have just told us to our faces?" Ruby groans.

"I know right?" I agree.

"Still, it's still a bit surprising how much cool stuff you can do. I didn't know anyone could run this fast, Onii-chan." Illya says, rewetting to my sprinting speed.

"I trained a lot, like I said. One of those things I worked on was my speed, not just in combat, but for things like this." I explain.

"Good thing your crazy over preparation came in handy." Ruby jokes, knowing about me wanting to keep Illya safe.

"Hey, in a world with moralless Magi, pseudo-vampires, and an eldritch spider thing, one can never be too prepared." I say dryly.

"Eldritch spider thing?" Illya asks.

"Less you know about that fucking thing, the better." I say, seriously.

"Ah. You know about that too." Ruby says, with a tinge of surprise and fear.

"Zelretch tell ya about it?" I ask. Ruby hums and nods. "Good. Then here's a tip: stay the fuck away from South America."

Illya just shakes her head at my antics as Ruby nods with a chuckle.

After a few more minutes of running, we arrive at our meeting spot, Rin, Luvia, and Miyu already there, the latter transformed as Sapphire hovers near her. I come to a hard stop, kicking up dirt as I drag my feet across the grass. The three girls and stick all blink in surprise at my entrance.

"Hello there." I greet, Illya awkwardly chuckling on my back. Miyu smiles and shakes her head as Illya climbs down.

"Honestly, I'm starting to think I need to temper my expectations around you, Emiya-kun." Rin grumbles.

"Oh? And what gave ya that clue?" I deadpan, much to Rin's frustration, which brings a smile to Luvia's face. I thank god that she doesn't do the ojou-sama laugh before me. "Anyway, these two already clue you in on the Install trick?"

"That they did." Luvia nods. "You can imagine my surprise when Miyu-chan changed into those clothes."

"Those clothes?" I repeat, raising an eyebrow. "Ah, right, Cú Chulainn." I groan.

"I suppose I should expect you to know which Servant the cards hold." The brunette magus comments.

I nod. "There's an alternate timeline to this one where these exact Servants got summoned for a Grail War around this time."

"Grail War?" Illya asks.

"Also known as the 'Murder Death Kill' to those who know what it's actually about." I joke, chuckling.

"This is the first I'm hearing of this 'Grail War'." Rin admits.

"Huh?" I blink in surprise.

"Oh-ho! So even you can get caught off guard, Sherou." Luvia smirks. Oh yeah, she also started calling me by name after finding out that I'm more casual than the usual Japanese guy.

"I suppose I should figure out when the last one happened." I muse. "Anyway, to summarize: Seven assholes summon seven Servants, kill each other, and the last one around gets a wish. Though, in that alternate timeline no one ever got a wish, they all just killed each other."

Illya's brows furrow and Miyu's eyes narrow.

"From what I understand, there have only been three Holy Grail Wars in this timeline, Shirou-san." Sapphire explains.

"So the fourth never happened..." As expected.

"Doesn't that thing happen every sixty years?" Ruby asks. "If it's the same as it was here, wouldn't the fifth be fifty years from now?"

"No." I correct. "Again, to summarize: Some idiots summoned an evil god as an Avenger class Servant in the third one, then he lost and went back to the Grail, corrupting it. When it showed up near the end of the fourth, one of the Masters realized it'd kill everyone or worse, so he used all three Command Seals to make his Servant use their Noble Phantasm on the thing to destroy it. Problem is, it just cracked like an egg, released cursed mud and fire everywhere, destroying most of the city and killing a bunch of people. To make it worse, the Grail absorbed the mana from the Noble Phantasm, specifically fifty years worth, making the Fifth War happen ten years after the last."

Everyone takes on a thinking expression, mulling over that info.

I continue. "Anyway, the pattern has followed the Servants from that Fifth War exactly, so I can guess who's next."

"So you know which Servants are in the cards?" Miyu asks.

I nod. "Saber's King Arthur, who's actually a girl named Artoria."

"King Arthur?!" Rin shouts. "But, why did she look so..."

"Evil?" I finish, getting a nod from the Japanese magus. "In one of those timelines, the Fifth War ended up getting... messy. More so than the other versions of that war. Saber got corrupted by the Grail's mud, empowering her by a stupidly large amount. The Berserker of that War, who was nigh-unkillable, would fuck her up normally, but in that Blackened state, she kicked his ass."

"And Lancer is Cú Chulainn." Miyu points out. "And you said Caster was Medea?"

I nod. "Rider was Medusa and Archer is a fucking asshole. Less said about him, the better."

"Why?" Illya asks.

" 'Cause I said so." Illya pouts at my non-answer. "I know what he can do, but I'd rather you not know who that guy is. He's... hard to get along with, let's leave it at that." I explain. Miyu's face turns to one of confusion at that. Ah, she knows who it is. I guess she doesn't know how her brother could be mean.

"So who's Assassin?" Ruby asks.

"Either Hassan of the Cursed Arm or Sasaki Kojirou." I say.

"Either? Where there two Servants summoned?" Sapphire asks.

"Kinda. Caster summoned Assassin herself, being Medea, but there technically was already one. Like I said, that War was messy." I say.

"And Berserker?" Luvia asks.

"Yeah, you made him out to be a big deal, but he can't be that bad." Illya says, hopeful.

"Heracles."

Silence reigns after I say that.

"Well... It's not that bad... right...?" Illya says, cautiously.

"All of his stats, save Luck are A save for Luck." I say, causing the Magi and sticks to grimace. "He also can't be hurt by anything under A-rank. Also, one of his Noble Phantasms gives him twelve lives, and, when killed, gets a resistance to whatever killed him- meaning, you need to kill him twelve different ways or take multiple of his lives at once."

"...That's." Luvia grimaces further.

"Yeah." I say. "Thankfully, if we run into him, he'll be weakened. Not by much, but still." I turn to the smaller girls. "Let me be clear, if it's Assassin, you two are gonna fight him. With your new trick, you'll stand a decent chance. I won't interfere unless absolutely necessary. But for Berserker? I'll deal with him. Unless you get really good at useing that Install trick, he's absolutely OUT of your fucking league." I stress. "Understand me?"

The girls nod.

I smile. "Good. Now enough talk, let's go and get 'em."

They all nod.

The Mirror World is as odd as I remember, despite it being my first time actually in it. I know I'm in the forest now, but it doesn't feel like it at all. It's funky.

"There's no sign of the enemy or the card. What's going on?" Luvia grumbles.

"Did we get the wrong place?" Illya asks.

"That's not it." Rin corrects. "Since there's a Mirror Surface World here, the card responsible must be nearby."

"I see, that makes sense." Illya nods.

...Do they seriously not sense it?

"Still, best to get those cards ready." Rin says. "You brought Saber and Archer, right?"

Illya nods.

"I have Lancer and Caster." Miyu adds.

"By the way, the space seems kind of small this time." Illya says, looking at the sky.

"It's proof that collecting the cards reduces the distortions' sizes." Rin explains. "The first few spaces were a few kilometers wide." Illya blinks at that.

They really don't sense it, huh?

"No use lamenting over it." Luvia chides. "For now, let's walk around and search for it."

"Okay." Illya nods, sadly, a bit upset oddly enough.

"And no splitting up." I say. "Last thing we need is that."

Everyone nods as we being to walk through the forest. Really? None of them sense it? I mean, it's Assassin, but still.

Illya looks around as she clutches Ruby to her chest. "I don't see it."

"This is pretty boring work." Ruby says, sounding exhausted already.

"I guess so." My sister smiles.

"We should act more like magical girls and use a more lyrical method of searching, like firing blasts of mana to light this place up!" Ruby says, sounding like a pyromaniac.

"That's not searching, that's destroying." Illya sighs.

"Now is the time to use that technique: Lyrical Radial Genocide!" The red stick cheers.

"Sounds like a reference." I chime in, eyeing the stick. Ruby just puffs out her 'chest', proud as can be.

Illya pauses and turns around, curious.

"What's wrong, Illya?" Rin asks, noticing her stopping. Huh, seems she noticed finally.

"I may be imagining things, but I thought I saw something mo-" The magical girl begins to explain, but...

fwoosh CATCH

...she gets interrupted by me moving in front of her, catching a thrown knife that was aimed right for her neck.

"WAH?!" Illya shouts, jumping away from me. Rin, Luvia, and Miyu all tense up.

I smile at my sister. "I told ya it'd be Assassin or Berserker." I say, before casually tossing the knife up and catching it as it falls. "Though it seems I was wrong about WHICH Assassin it was."

"What do you mean?" Luvia asks.

"It's the Assassin from that world's Fourth War, Hassan of the Hundred Faces." I say, feeling annoyed by the bait-and-switch.

"Hundred... Faces?" Illya asks, clearly a bit shaken by the near-miss.

"There are currently seventy-five enemies in the forest. We're surrounded." I say, simply. I guess they're weakened in more than just their stats.

"EHH?!" Illya shouts.

Sure enough, a being emerges from the forest, covered in black and wearing a skull mask upon its head. Then, another comes out. And another. And another. Soon, around seventy Hassan surround us, all carrying knives.

Rin pulls out some gems. "Nobody told me there would be an army of these!"

"Servants don't play fair." I remind, before looking down at Illya, clutching Ruby tightly, her breathing a big haggard. She's scared. Really scared.

Sighing, I place a hand on her shoulder. Illya's eyes meet mine, fear clear in her red orbs. "You have that new power of yours. These guys are nothing. I believe in you, Illya."

"...!" She gasps, looking up at me, her fear and worry evaporating before me. She exhales slowly before nodding.

I smile back. "Good. Saber might work, but Archer would likely be best here. Same with Lancer, he's more a single target."

Miyu nods as the magical girls nod, determined. ""Install!""

Light engulfs the girls, soon it dies, revealing them transformed. Illya wears something similar to EMIYA, though it reveals her stomach and her legs, since she doesn't have pants or anything, just his weird belts. Miyu is wearing Medea's outfit, though it's missing the cowl and is cut high at the left hip, revealing black panties.

I hum appreciatively at their new forms. They definitely look sexy. Lord knows I'm weak for stomachs and hips. "Nice. Now, kick some ass. I'll be here if things go wrong, but don't think about relying on me. You two have got this."

The girls nod as Miyu summons up Medea's staff and fires a massive fireball, taking out quite a few of them- at least a dozen.

"Um... how do I...?" Illya blinks.

I groan. "Say 'Trace On'."

"O-Okay. Trace On?" Illya says, questioningly. In her hands, Archer's bow shows up, along with... ah, Caladbolg. She raises the spear-like sword and the bow, drawing it back and stretching out the blade into an arrow. She lets it fly. The 'arrow' explodes on impact, blowing up more of them. Miyu and Illya keep this up until some Assassins throw daggers at them, but Miyu is quick, making a barrier around her and Illya before they quickly retaliate.

"Unbelievable..." Rin mutters in awe at the duo.

"This is... the Cards' true power...?" Luvia asks, also in awe.

"Yup." I smile, crossing my arms. "Look at 'em go! Took them a few seconds to use those things to near their full potential." I say near because Miyu isn't using those High-Speed Divine Words of Medea's, nor is Illya summoning any other swords, save for more Caladbolgs. I guess she just wanted an arrow and went with it.

But to my surprise, Illya mutters something as she draws back another 'arrow'. "My core is twisted in madness." I smile as the arrow twists on itself, before firing off faster than before. It then explodes with greater force than the other ones.

In mere moments, all seventy-five Assassins are killed. As the last one falls, a single card is left behind where its corpse fell. The girls Uninstall as Miyu walks over and picks up the card, whereas Illya falls to her knees, breathing heavily. I walk over to my sister. "Used a bit too much mana there?"

Illya plays along with my guess, saying, "Y-Yeah." I know it ain't mana exhaustion. She's still overwhelmed by that near-miss. I can see it in her eyes.

Miyu walks over, holding a hand out to Illya, who takes it and stands back up.

Rin sighs in relief. "It's good you two had that Install ability, that could've been bad."

"I agree. Sherou's tricks came in handy." Luvia adds with a smile.

"It certainly was a surprise." Sapphire adds.

"Servants don't play fair." Ruby echoes my words with a laugh.

"Well, I'd say you two have got a pretty good hang on the Install. Speaking of, hand me the Assassin card." I say. Miyu nods, handing it to me. Quickly, I look it over before handing to back to her with a groan. "Include lets you make a clone, Install lets you make a more durable clone, plus you get a knife."

"That's it?" Illya blinks.

"Well, that and the stat increases Install gives." I shrug. "Anyway, let's get outta here."

With a collective nod, Ruby and Sapphire open the portal back home. Once through, the magical girls untransform. We all ended up walking together back to our houses, Luvia, Rin, and Miyu splitting up when we got to our house.

Illya and I went back inside and laid back down together in a spooning position, my arms wrapped around her soft stomach.

"Are you okay, Illya?" I ask.

"I'm fine, Onii-chan." Illya retorts, a bit quickly.

"Illya..." I say, not believing her.

She softly sighs, grabbing onto my arm. "It's just... When you caught that knife, I remembered how dangerous that world is." She admits, causing my chest to clench.

"I'm sorry."

"For what?" She asks.

"Letting you get into all this."

"Onii-chan." She says, sternly. "I told you, I forgive you for that. It just... It was a strong reminder for me to not take this stuff lightly."

"...There's a good quote for this." I begin. " 'To be a magus to to walk with death'. Either yours or others, this world is fucking dangerous."

She lets out a deprecating chuckle. "I can believe that... But enough of that. It'll be fine. We'll get the rest of the cards and no one will get hurt." Illya says, optimistic.

I smile. "Yeah." I say, nuzzling against her. "It'll all be fine."

"Sweet dreams, Onii-chan."

"Sweet dreams, Illya."

BONUS: Magical Girl ORT-tan

"You know... I was thinking..." Ruby muses.

"Oh, fuck." I say, wide eyed. "Ruby's thinking!"

"Hush!" The stick shouts as her sister and their wielders all giggle. "I got to thinking... Illya-san and Miyu-san don't have rivals!"

"Rivals?" Miyu blinks.

"Yeah! Magical girls always have a magical girl rival!" The red stick says. "I thought maybe Miyu-san would be her rival, buuuut..." She says, slyly.

"Yeah, I get it, but where's the point?" I deadpan.

"We should find them a rival!" Ruby says.

"And how are we going to do that, Nee-san?" Sapphire asks.

"I dunno!" Ruby chirps.

"Seriously?" Illya deadpans.

"Actually..." I hum.

"Eh? You have an idea?" Ruby asks.

"Maybe." I say, standing up. "It... miiiight be a bad idea, but fuck it. I'll be back in a bit." I say, walking to the door.

The door closes behind the boy as he leaves.

"...Why do I feel this sense of overwhelming dread?" The albino asks.

"I think I might've made a mistake." Ruby grimaces.

"I'm back!" The boy shouts, coming back inside.

"Oh? Did you find a- WHAT THE FUCK?!" Ruby curses, to everyone's surprise.

"Sh-Sh-Shirou-san?!" Sapphire stammers, scared as hell.

"Why are you two yelling?" Illya grumbles as Miyu and her find themselves blinking in confusion at someone next to Shirou.

It's a young girl around their age, with lime green eyes, long green and blue hair which turns spikey at the end, and pointed ears. She wears a strange, silver crown thing decorated with glowing green gems, a green and gold shirt/short skirt combo, and gold boots. She also carries a staff and has a confused, yet mostly blank look on her face.

"Ah, let me introduce you to your new rival-slash-training partner!" He says proudly, placing a hand on the girl's shoulder and using his other hand to gesture to her theatrically. "If we're going with Ruby's naming scheme, she'd be Magical Girl Mercury-chan."

"M-M-M-M-M-" Sapphire begins stuttering like crazy as Ruby freezes.

"Mercury-chan?" Miyu blinks, tilting her head.

Illya goes with it, beaming at the eldritch alien machine thing-turned-meguca. "Hello, Mercury-chan! I'm Illya!"

The new girl blinks her green eyes. "Hello, Illya. I am Magical Girl TYPE-Mercury."

Ruby collapses to the ground.

"Eh? Ruby?!" Illya shouts in fright.

"Sapphire's broken." Miyu says, noticing the blue stick twitching, before it falls to the ground next to her sister.

ORT looks up at Shirou. "Humans are strange."

"Oh, yeah, but that's what makes us great." Shirou smirks down at ORT-tan. "I'm sure you'll find some great things about the human world too, Merc."

"Merc?" She blinks, before looking at her fellow magical girls worrying over the knocked-out sticks. "I see..."

A small, almost unnoticeable smile blossoms on the alien girl's face as she watches the strange humans, an odd feeling welling up inside of her.

"Friends with... humans..."

AN

Illya's got the 'Chloe stuck in your head' Syndrome. Good luck, Illya-chan! You're gonna need it...

Miyu's outfit during the start can be found on the website which name starts with Gel and ends with booru. It-It's Gelbooru. Some of you had trouble figuring it out, funnily enough. Same with nhentai (dot net, not dot to). Specially, it's post number 4898276- but without the side ponytail and jacket- by Hiroyama Hiroishi- the Fate/Kaleid manga author. He draws good shit.

Also, look up ORT-tan, she's pretty cute.

I hope you enjoyed this chapter and look forward to the next!
