Sounds of footsteps can be heard walking down the stairs as Shirou turn his attention toward the hallway. It wasn't long until Emilya enters the living room, looking quite tired as she let out a soft yawn.

" Tired? Come here, I made something for snacks, maybe that will refresh you ", Shirou who's sitting on the couch and watching some kind of show on the television lifts a plate from the small table.

The contents on the plate are takoyaki, it's still steaming so it wasn't long before it was being made.

Emilya, who's wearing the miniature version of Liz's clothes from when Liz's secretly stalked her but with a purple and yellow stripe instead of green and white stripes tank-top and blue shorts instead of a brown one.

Of course, it was Liz who bought them for her. She walks over and sits on the couch with Shirou and take his offer.

" Takoyaki? Are you craving for octopus or something? It's kind of weird to have it for snacks, then again, I'm not complaining ", Emilya pokes one of the takoyaki with a toothpick before blowing on it to cool it down before popping it in into her mouth.

Shirou put the plate back down on to the small table before taking one of them himself.

" It's fine to have them once in a while, it's not like we have them every single day. Plus the one we usually get from the takoyaki stall is closed due to the people who work on it are going on vacation.

Either way, we can agree that mine taste better right? ", Shirou declare proudly before popping the takoyaki into his mouth and panic later because he forgot to cool it down.

" Oh? Are you perhaps challenging me Shirou-san? I agree that yours taste better than them but if I have to compare them to mine, I can proudly say that mine is better ", Emilya poke Shirou's face in a teasing manner. Shirou swats her hand away softly before grinning at her.

" Maybe I am? How about a cooking contest on the weekend? Illya, Liz, and Sella can be the judges ", Emilya folds her arms as she grin and responds back, " It's a deal ".

She looks at the television which is showing some kind of competition game about winning a holy grail war, she can't help but snort at it. ' If only the holy grail war was that simple ', Emilya shakes her head before turning her attention to the hallway upon hearing the front door open.

It was Illya who's still in her school uniform, she stayed behind at school to catch up and discuss with her friends about the next assignment while Emilya left immediately.

Emilya was so tired due to, in Emilya's quote, ' Unknown Lewd Forces ', she was receiving and enduring that she needed to take a break as quick as she can before she stresses out.

Emilya notices that Illya seems to be feeling down, she can't help but worry about what might have happened to Illya during her absence. Illya sees her sister looking at her with concerns showing in her eyes, she tries to hide it behind a forced smile, it seems to work for her brother.

Emilya, on the other hand, got even more worried.

Before Illya could leave and go to her bedroom, Emilya causally stood up and walk over to Illya with a smile.

" Let me accompany you to your room, I have something I want to ask you ", Illya could tell her smiles was also forced, she could guess that Emilya doesn't want to worry her brother by playing a facade. Shirou looks at them with a tilt of his head, confused.

" Couldn't you just ask her here? ", Emilya turns around to answer him back, with a teasing smile on her face as she leans over and licks his nose.

" Are you really that curious~ You want to know what kind of questions I want to ask? Well I could tell you but it will cost you a lot~ ", both Illya and Shirou started blushing furiously as Emilya's face is getting way too close for comfort from Shirou.

Illya looks like a goldfish, constantly opening and closing her mouth as she tries to search for words to form.

Before Shirou can retaliate back, Emilya immediately walks away from Shirou and grab Illya by her wrist before proceeding to walk upstairs really fast. Her face is now red due to her embarrassment. Shirou was dumbfounded, his body finally relaxing and letting out a big sigh that he didn't know he had held.

" What am I going to do with her. She's much wilder than what my first impression of her that I had before ", placing his attention on to his television, he started to think about what his life would become with his new sister probably playing a major part in it.

* Illya's Room, Illya Pov *

" So, uh, Nee-san. Why did you do that to Onii-chan? ... Nee-san? ", I ask my big sister as I try to understand my sister's action.

She just turns her back facing against me while covering her face with both of her hands and started whining about something. I can't tell, but I think she is blushing from embarrassment, her ears are bright red. She turns around and gives threatening looks which make me gulp my saliva nervously.

" If you tell anyone about what happened, I will make you suffer even if you're my adorable little sister ", I can't tell if she's trying to threaten me or tries to compliment my appearance.

Well even if she says that I can't really have the guts to tell anyone about that, especially Sella, she will kill Onii-chan, that's for sure even if it was my sister that took the initiative. Emilya did a mock cough before looking serious at me.

" So tell me the truth and don't lie, I know when you lie. What happened? ", she crosses her arms waiting for my answers, I can only twirl my index fingers around each other as I nervously answer back.

" Well... I encountered Miyu again at the park, she asks me about why am I collecting class cards and putting my life at risk for it. I answered her honestly and she got mad, I didn't know what to do. She immediately left before I get to chance to ask why she is angry. ", I answered truthfully and my sister only raise an eyebrow with a curious look etch on her face.

" What did you say? ", I answered back with, " I thought it will be fun to be a magical girl and collect magical cards, it's like living in an anime you know? ". My sister's face is very stoic after hearing my reasoning, I am pretty sure she is still processing what I said inside of her head.

She let out a deep sigh before placing her left hand on to her forehead and shaking her head. I don't know why but I feel very sad right now.

" Illya, come here ", Emilya sit on the edge of my bed and invite me to sit with her, which I accepted.

" Illya, I think the reason she's angry at you is that you're taking this situation too lightly. Think about it, do you think Miyu is doing this just for fun? She's taking her job seriously, knowing that she could possibly die from those servants. In fact, I am also very worried about having you to fight one of those deadly servants, so even if I was forced by Rin to participate, I joined the fight so I can protect you Illya ", I can tell that what Emilya-nee is saying is very genuine and came with lots of love from deep within her heart.

It warms me up to know that she cares about me that much, I don't think I had ever done anything to deserve such caring sister. Is it because she's a family member now? That can't be, it always feels like we knew each other for so long despite that we haven't even met once before in our life.

I let Emilya-nee's words sink into my head, I think I understand now. I was really foolish, wasn't I? To think of our situations as nothing but a fantasy game.

" Thank you Emilya-nee, I am happy to know you care about me, I think I understand better now ", I give my big sister a big hug, she hugs me back and even ruffles with my hair softly, not to ruin it too much. I will start being helpful for Onee-chan and Miyu and work much harder than both of them. I guess I will need to apologize to Miyu when I meet her again.

" Aww isn't that adorable, now get up, we have something to discuss ", Rin who casually entered from outside of my window says it in teasing with a mixture of mocking tones in her voice. I immediately stand up and look shocked at her as I stuttered with my next words,

" Ri-Rin-san!? Ho-How did you get up here!? ", I mean, this is literally the second floor. Before Rin-san can answer back, it was Emilya who spoke up next.

" Reinforcement I presume? It's not like you know any flying magecraft right? ", Rin just nod at her before narrowing her eyes on my sister.

" And how would you know what I'm capable or not capable of, young girl? ", Rin places her hand on her hips as she leans down toward Emilya-nee, looking at her straight in the eyes. I see my sister sweating furiously for some reason, is it hot in my room?

" I mean, flying magecraft is hard to learn so I thought maybe even if it is you, you wouldn't be able to learn it without the help from your kaleidoscope stick ", I see, so flying magecraft is hard without Ruby, I wonder if I should try flying next after I transform again. Rin seems to be skeptical about her answers though.

" ... I will let you off with that, though I do have one more question ", I can see that Emilya-nee is shaking nervously, there's seem to be more things that I don't know about her as times passes.

" That spell of yours, Rho Aias was it? I did some research on it and I found something interesting ", at this point Onee-chan is sweating bullets. I also wanted to know about what that spell was, it was beautiful and able to block that masked lady powerful attack.

" Rho Aias, also known as the famous shield of Aias the Great who stopped the spear of Hector, Durindana, which was known to be able to penetrate all kind of defense during the Trojan War ", with this new information, I can't help but be shocked at what I just heard.

I don't know anything about the hero of the past, but hearing something such as a spear that can penetrate any tough defense being stopped by a shield that my sister had created sounds amazing and impressive.

How did my sister manage to create a legendary hero's shield from the past?

" The-There's an explanation for this, you see, the shield you saw wasn't a real one. It's a Conceptual Weapon ", Rin looks confused for a moment and so did I. What is a Conceptual Weapon?

" Conceptual Weapon? ", Rin asked, I guess I don't need to ask any more then.

" Yes, Conceptual Weapon. The shield I created is a form of projection magecraft which is more advanced than your regular projection magecraft. With this magecraft, I can make Conceptual Weapons such as Rho Aias which is a weapon that has the concept of absolute defense against any thrown or projectile attacks such as what the legend had said about it being able to stop Durindana after being thrown toward Aias himself. So I gave the shield a name that suits them properly for what they are capable of ", uwa, so many pieces of information, my brain is frying. Yamero Emilya-nee, you're hurting my poor brain.

" So you're saying that it isn't the real shield of Aias the Great, it's just a made up shield that has the concept of absolute defense against any thrown weapons? Never knew projection magecraft was capable of doing that ", Rin holds her chin with her hand while mumbling something that I can't understand, wait if Rin didn't know about this how did big sister learn about it? Before I can ask again, Rin interrupted me.

" Anyway, thanks for the information, I'm sure we can put that specialty of yours into good use. Is there anything else that I need to know? ", Emilya-nee looks like she was about to respond back before stopping midway. She shakes her head but I have a feeling she's lying.

" Good, now get ready and be prepared. Luvia and I found the next location of the Class Card so we will deal with it tonight. Meet me under the bridge, you know, the closest one where it goes over the river ", we nod back at her.

The next Class Card... I wonder who it's going to be. I remembered Rin said there're seven which are Saber, Archer, Lancer which is famously known as the knight class.

And there's the rest which is Rider, the one Emilya's holding on to, Caster, Assassin, and Berserker. I don't think I'm looking forward to Berserker, whoever that hero is sounded terrifying, probably some kind of barbarian.

With that, Rin left our room via my windows and Emilya left to her room afterward to get prepared, well, at least that's her plan before literally out of nowhere she got abducted by a certain Liz who zooms across the hallway and manages to pick Emilya-nee up without stopping. I sweatdropped, seems like Emilya-nee can't really take a break huh.

*Night Time Under The Bridge, Normal POV*

" . . . You really do like to wear that magical girl costume, don't you? ", Rin asked but it's more of a statement than a question. Emilya just sighs tiredly.

" Again, not by choice. It's as if a certain big sister of mine knew I would be going out collecting Class Cards and put me in these clothes. I swear her timing is suspiciously accurate, plus she's very obsessed with these clothes in particular for some reason ", Rin can't help but gives a strange yet amused smile.

Not too long later, Miyu and Luvia finally arrived. Something they didn't expect for the next thing to happens is that Luvia points her finger at Emilya and declare,

" Emilya, how about working for me instead of this nobody! I heard about your capability from Rin herself who was boasting at me about your specialty. Your power will only rot away if you fall into her hand, but if you are in my hand, I will make sure to sharpen your skills and make you the best magus there will ever be! ", "Uwa...", that was a form of reply from Emilya herself who has a worried look completely shown on her face.

Rin, on the other hand, is gritting her teeth so hard that you can probably see a spark ignite every time she grinds her teeth together.

" Back off, I got here first so she belongs to me! ", Rin shout back at her, anger slowly building up from within her mind and body.

" Am I an artifact now? I feel like they don't see me as a human anymore ", Emilya's feeling dejected as she proceeds to crouch and draw circle on the wet mud. Illya walks over to her sister and pats her back, giving encouraging words to her depressed sister. Miyu tugs on Luvia's clothes, which earn her attention.

" ... Class Cards ", Luvia finally realize what she meant. They came here to collect Class Cards, not to pick a fight.

" Ahem, we will hold this discussion later. For now, let us get going. Miyu, proceed with the jump processes ", Miyu nods and casts her mirror world jump along with Illya who did the same.

" Hey uh, don't you think we should be making strategy first before going in? There could be traps waiting for us on the other sides ", Emilya nervously suggested which make both Rin and Luvia look at each other before laughing at her.

" Eh? ", Emilya was confused about why they're laughing at her.

" Emilya, the servants we are going against are corrupted and mindless heroes who no longer have the ability to think for themselves. Do you think they will be able to have the ability to make traps? ", Luvia confidently answers back at her, who on the other hand doesn't look too sure, even Illya and Miyu are having a second thought.

The area around them started changing slightly, but before they completely enter the mirror world, Rin gives her own answers.
" Relax, nothing will go wrong. As much as I hate to agree with her, she's right. What's the worst thing that can happen- "

*10 Seconds Later, Real World*

Five charcoal figures can be seen under the bridge, pilling upon each other in this order from bottom to top. Emilya, Luvia, Rin, Miyu, and Illya.

The moment they had entered the mirror world, they were met with Caster who was floating in the sky, waiting for them to appear as if she knew they would come to get her. So logically, she set traps, LOTS, and LOTS of traps. Magic circles cover the vast skies, and every circle emits laser pointers, which was aiming at the group.

They manage to escape the barrage of magic lasers but not without getting burnt themselves.

" You guys are heavy, get off... ", Emilya groans painfully, she knew she should just force them to listen to her and actually make some plans just in case something like that situation happens. They finally got off her back and leaning against the bridge's pillar.

" Ahem, well... that was unexpected ", Luvia tries to laugh it off while Emilya's giving her a death glare. She's giving the look that says, ' I told you so ', which makes both Luvia and Rin flinched.

" More importantly, how are we going to fight her? She's floating in the sky, making her a hard target to hit our attacks with. Not to mention her limitless magic circles that are waiting to be unleashed upon us ", Illya complains about their complicated situation. Rin and Luvia are thinking furiously about what plans of actions should they take.

" Illya, Miyu, can't you just fly? You do have Ruby and... what was your name again? ", Emilya asks the wand with a blue ribbon attached to it, the mystic code that Miyu uses in battle.

" It's Sapphire Emilya-san ", Sapphire replied politely which Emilya still can't believe that a mystic code is capable of such politeness, she guess not all mystic codes are like Ruby.

" Oh, so I just need to fly right? ", Illya started floating off the ground which surprises everyone other than Emilya. Luvia immediately turns to her young partner and orders her to do the same which Miyu replies back seriously and logically, " People can't fly! ", Luvia falls down at her answers.

Luvia drags Miyu away to their house leaving two trails of line on the mud from Miyu being dragged by the collar of her clothing. The house is actually a mansion across the street from our house, how did it appeared without the sisters or at least Liz and Sella knowing? They don't know either.

" Well we will continue later after Miyu is ready to learn how to fly, so meanwhile, do some exercise or practice with your Kaleido-stick. I will think of a plan later, right now I want nothing to do other than taking a good warm bath and go to sleep ", with that, Rin walks away slowly, wobbling from left to right and fall sometimes, seem like she's out of energy.

" Well Illya, I guess we should do the same too ", Emilya, despite being so tired, manage to walk properly toward her next destination with Illya follows behind.

" What if we woke our family up? ", Illya asks anxiously, she doesn't know how to answers if their sisters or their brother find out that both of them are still up in the middle of the night, taking a bath.

" Just says that we were sweating so much when we were sleeping and doesn't want to go back to sleep while the sweat stick to our body and to our clothes, which isn't technically a lie since we actually are sweaty right now ", with that, both siblings arrive at their house and had a great bath together. They have to resist falling asleep while in the bathtub. They manage to do everything they needed to do without waking up anyone before going to sleep.

" Hopefully everything will be alright next time, Caster eh. This isn't going to be easy, knowing how crafty and tricky she can be ", with that she turn off the glowing lamp on her small drawer beside her bed before dozing off into a deep peaceful sleep, dreaming back to her times spent with Sakura, Rin, Medusa, and even Taiga back in her world.

But what she didn't manage to notice is that her Rider Class Card is glowing beside her lampshade.
