"No, this... this isn't right!"
Shirou Emiya realized Jiang You was trying to set him up. How could he joke about such a serious matter? "Miyu, listen to me! It's not what he's saying!"
Typically, any attempt to explain only makes things worse. The Shirou Emiya from the other world would have sacrificed the entire world for his sister. But this Shirou hadn't experienced such turmoil yet, remaining pure and naive, still believing the path of a Hero of Justice was a starlit road.
Miyu gazed at the dagger in her hand, her expression hesitant. She had never harmed anyone before. Stabbing her brother with such a weapon, even if he only resembled her true brother, felt impossibly difficult.
"This flimsy dagger won't even pierce his skin. You'll need this."
Archer suddenly materialized, replacing the plain white dagger in Miyu's hand with Bakuya.
"What's your business here again?!"
Shirou Emiya glared at his future self, grinding his teeth. Though they had reached a truce, their animosity remained palpable, and they never missed an opportunity to snipe at each other.
"Whenever someone opposes you, I can't resist stepping in to even the odds."
Archer crossed his arms and shook his head. "What use are Fuyuki weapons now? Unless Shirou Emiya is some kind of ultimate masochist who'd actively accept this kind of damage."
"Please don't install strange things in other people's houses for no reason." Illya switched the lights back on with a speechless expression. The stage play's fantastical atmosphere instantly vanished. She pointed to the spotlight on the ceiling, and Hundred Faces very compliantly dismantled it. The rule that "my Master's Master is not my Master" clearly didn't apply here.
The entire scene collapsed in an instant, leaving Miyu staring silently at the Projected Noble Phantasm in her hand.
"If this is my illusion, then who are you?" Miyu fixed her gaze on Jiang You, a young man she didn't recognize at all. If this is an illusion, shouldn't there be someone real to correspond to him?
"Illusion sprite?"
"Can't you come up with a normal name?!" Rin Tohsaka couldn't resist retorting, nearly spitting out her black tea at the absurdity of the name.
"If you can't think of anything, just end the topic!"
"...Naughty child!" Tiamat's tiny fist pounded Jiang You on the head, triggering his Duel invitation protection. "Don't bully Miyu! She came to this unfamiliar place all alone. Don't make her even more troubled."
Even Miyu, who was oblivious to many things, understood that this wasn't her original world. Yet the people here seemed to recognize her, and there was even someone who looked exactly like her brother, Shirou Emiya.
"...Alright, so the plan is to have Miyu Duel Shirou Emiya to summon the Shirou Emiya from the other world, right?"
To access another Script, the corresponding character had to agree. Jiang You wasn't entirely just messing around. Besides, even if Miyu stabbed him, it would only trigger a Duel.
"Miyu, you probably understand the situation by now, right? In short, your brother's wish has come true. This is indeed a world where you can escape your suffering, meet kind people, and make friends with whom you can laugh together."
With Shirou Emiya, Illya, and the Class Cards (Yu-Gi-Oh! Cards), this was undoubtedly the world of Magical Girl Illya.
"In short, welcome to the world where only Illya can't find happiness."
Before Jiang You could finish speaking, Illya elbowed him.
"Explain yourself clearly! What do you mean 'only I can't find happiness'?"
"Even so..." Miyu could indeed sense the warmth and friendliness radiating from the people around her. But even if staying meant betraying Brother Shirou's kindness, she had to return to his side. She couldn't possibly trade his safety for her own comfort.
"I have to go back! My brother is waiting for me!"
"I knew you'd say that."
Jiang You shrugged off Illya's restraint. With Illya's physical capabilities, there was no way she could overpower a servant with maxed-out stats; he had simply been humoring her. Jiang You pressed the Bakuya he had retrieved from the ground back into Miyu's hands. "So, attack the Faker (Shirou Emiya). Use him to welcome your true brother."
"Isn't a Duel just a matter of issuing a verbal challenge? Please stop with these theatrics!"
Shirou Emiya quickly sent Miyu a Duel invitation, desperate to prevent Jiang You from stirring up more trouble.
"Tch, how boring. I was hoping for a heartwarming scene of brotherly and sisterly affection."
Jiang You sighed, lamenting that even his recent attempt to find some entertainment had been interrupted.
"This... what is this?" Miyu asked, an expression of confusion on her face as she received the Duel invitation.
"Think of it as our Fuyuki's version of combat rules," Jiang You explained simply. "You use Class Cards, while we use Duels. The Duel rules are already imprinted in your mind, so you should know the basics. The servants summoned are all connected to you. The 'Shirou Emiya' you hold is your true brother."
"Does this mean I can rescue my brother too?" Miyu's large eyes filled with hopeful anticipation.
"Of course not," Jiang You clarified. "Summoned servants disappear after the Duel ends or when they leave the Duel Space, returning to their original places."
Jiang You was the only one capable of summoning projections with their original consciousness. Theoretically, if he could reach an agreement with Emiya, he could directly pull him over. However, considering the Faerie Realm's ability to block summons of Pan-Human History Heroic Spirits—even Jiang You's effect summons could be prohibited—there might be special circumstances.
"As for what happens after summoning him, leave it to me. Regardless, you should at least let your brother know you're safe, right?"
Jiang You's methods were essentially two: one, the method already mentioned; the other, similar to the Sixth Singularity situation, requiring consent from someone in that world to summon him.
It's not like I'm going on vacation, Miyu thought to herself. But seeing how genuinely Jiang You and his group seemed to want to help her, she nodded obediently.
"Thank you all. I'll definitely repay you."
"There's no need. To me, you're just like..." Shirou Emiya began to refuse, but Rin Tohsaka quickly clamped her hand over his mouth. This idiot doesn't even realize he needs to reassure a little girl, she thought.

"Since this isn't a formal battle, I'll let you go first," Shirou said, immediately ceding the first move.
Miyu saw no need to be polite under the circumstances. She raised her hand, displaying her cards. "I'll make this quick... I activate the Spell Card Oath Under the Snow!"
