Notes:

I am not native speaker, my grammar might bad... No it really bad and I might miss spell something.

This is my first fanfic sooo enjoy maybe?

Chapter 1: I get power just like that?

Subaru slowly opened his eyes.

Only to hear a high-pitched sound coming in front of him “Oh! You Awake”.

‘Huh?’

‘Emilia?’

He looks in front of him only to meet with a woman.

Who he can't seem to figure out her face, her face is not covered by anything but no better how hard he tries to look at the face, he can't figure, the only thing he can see is she has short white hair and wears scientist-like clothes.

Now change from Emilia-like voice changes to a childish and mischievous voice “Hiii!” She waved her hand “how are you feeling right now?”

‘not bad actually… wait where am I, what is this place!’ but no sounds have been made out of him.

‘My voice isn't coming out! How!’ He looked around the place only to find nothing there, only white color filling the entire place.

"Ha! You make really funny right there!"

He tries to move his body but to no avail, his body stiff like a sand cover all over his body, the only thing he can do is his head.

‘What? I Can't Move!’ He tried harder but his body still did not move an inch.

He opened his mouth tires to shout at her ‘Who are you! And what did you do to me!’ but no single sounds came out of him.

“Hmmm sorry I can't read mind!” She laughing, shrugging it off.

“But I assume with that expression of you, you ask me who I am and why did I bring you here”.

‘You're only right about the first half!’ He tries to say it but there are still no sounds coming out of him, only the expression of how furious he is get sent out.

The woman brought both of her hands to hide behind her back “To answer your question I’m just being who has sooooo much time to spare”.

Subaru looked at the woman confused. 

“And to answer the second question”

“Why did I bring you here?” 

“You see when I travel through multiple world, go look here and there, but one day when I reach one place, I have found some very interesting technology, you know what it's called?”

Subaru opens his mouth and tries to answer, but she cuts him off immediately, even If he try to answers it, no sounds coming out from home anyway.

“it is called mephistopheles”.

‘Mephisto what?’

She faced away from him, raised one hand high to the sky and other hand placed on her chest “it the name of a bus”

‘it just a bus what so special about it’

She turns back to him “You think it just a normal bus but you wrong”

‘Wait did you just read m-’.

She wiggles her “mephistopheles, it is not just any normal bus, it uhhhh” she suddenly stops, closing her eyes, rubbing her own chin, try to think of something, that she shrang.

“really special bus that have many convenient abilities for traveling”.

“Anyway” she clapped her hand “The thing I'm really interested in the bus isssss the extraction ability!”

“Do you know what it can do?”

‘how would i-’ 

“It able to let you extract an identity from mirror world and utilize it"

'why would you ask me if you not going to let answer'

or if you do not understand what it is, just think as you are borrowing power from your alternate self and you knowwwwww what The fun part about this?” 

“I'm going to give this ability to you” and that point at him.

‘Huh?’

“For free!, you are not going to lose anything from this, no curse no tax no lose your nut for it! absolutely for free!” She raised her hand high to the sky 

‘Wait! Wait! Go back! Go back!’ 

She brings her hand down “After that sentence you going to either ask questions or really confused about it”

“But with face like that” she stared at him for a few seconds “I think you confused”

'No! I'm not! Wait no maybe I am?'

“Anyway” she clapped her hands “i want to give you becauseeee” 

She slapping the air like she slaps the drum and it somehow made a drum sounds 

“Why not?” she shrugged.

‘That-’

The sounds of cracking start to appear.

“Oh look like I ran out of time now!” she said it in a sing-song voice.

‘Wait what do you mean?’

The cracking sound gets louder and a crack begins to appear.

“G-I- H– B-C-!” he can hear distant cries coming out from the crack.

“No time to explain”.

She brings her fist at the level of her face, 

“I already leave the instructions on the extraction space. You could read it and to open the space”.

her fist starts growing a weird light around it.

“Just follow the star”

“Now hold tight and don't bite your tongue!”

‘WAIT WAIT WAIT’ he tried to shout but the only thing that happened was his mouth open and closing like a fish and face that looked so sacred he might piss himself.

She swing her fist straight to his left eyes.

‘AHHHHHHHHHHHHHHHH!!’

 

______________________

 

“AHHHHHHHHHHHHHHHH!!”

He jumped straight up from the bed, heart pounding and instantly put both of his hands to cover his left eye.

He looks around the place panically, only to find out he not with the woman anymore.

He eventually calmed with the open eye he looked at his own hand.

‘it… don't hurt at all…’ he lowered his hands.

“Was that just a dream?”

 He look around “where am I now”.

He looks at himself and opens his robe “looks like the wound is gone. Considering all this, it must've been her… Emilia's healing power”

He lifted his face up only the realization hit him like his dad woke him up.

His face lit up red like Reinhardt hair.

“Who the hell undressed me!”.

There was no answer, only the quiet of the room.

“Ahem!... Anyway it's not like I can just falling back sleep again”.

He jumped down from the bed, “should I wait for someone!”’ He walks around the room, slaps the bed, moves the chair around, moves the curtain, and looks at the beautiful garden below him, smiling.

“What a relaxing and beautiful scene” and then his smile instantly went down “and incredibly boring.

He walks straight to the door and walks out of the room.

 

______________

 

Subaru stepped into the corridor.

The incredibly expensive one then you are going to ask why are there gold on trim on things that should absolutely not have a gold trim on it.

He walks and walks and walks…

Wait that painting here again?.

He walks back and finds the same one, the weird Forrest painting.

He walks back again, same painting again.

He walks straight faster and faster, and then he start running.

He ran past the same painting again and again and again.

He eventually stops running and catches some breath.

“That confirm it this is definitely some sort of looping room”. 

He look at the besides.

“If this is one of those ‘choose the correct door’ things, then by anime logic... it’s gotta be the first one”.

He open the door besides him with a confidence that you are going to laugh at him if he chooses the wrong door but sadly it is the right one.

Once inside he comes face-to-face with a small girl sitting in front of the door.

“First NPC found!” Subaru said brightly and point at the little girl.

"What a profoundly aggravating man and a unique eye you have there, I suppose.”

“That cold glare’s gonna ruin your cute face, y’know”. He poke both of his cheeks “Smile! Sm-”

He stop his actions.

“Awww thank you I got these eyes from my mother” He pointed at both of his eyes smiling.

“It is not a compliment, I suppose and I don't mean those eyes” she pointed at his left eyes “I mean that”.

He dropped his smile “Huh what do yo-”. 

“hold tight and don't bite your tongue!”.

“Are there any mirrors in here?”

“I never need a mirror in this place, so there is none I suppose”. 

She jumped down from the chair “If you done questioning” and walked towards Subaru.

She reached her hand out on his stomach.

“Wait what you going t-”

“Gah! , Argggghh!” He fell flat to the floor.

“What did you do to me, drill Loli!”.

“I only collected your mana from your body, I suppose”

She stared at him coldly.

“It confirmed that you are not an enemy”.

He lifted his face up “you are not human, are you? And I don't mean your personality…”

She smug “it took you long to notice, I suppose”

“i take it back, you personality isn't human either”

She turned her back on him “Do not measure a proud, noble being by your standard, human”.

With that last word his eyes slowly shut close.

 

______________

 

Subaru once again on the same bed.

He opens his eyes only to meet the ceiling again?.

"Oh, he has awakened, Sister."

"Indeed, he has awakened, Rem."

Two voices spoke besides the bed as Subaru smiled to himself.

"Me, a denizen of the night, waking up in the morning? I'm getting all emotional. I'd better go to sleep a second time. No, I woke up earlier, so this makes the third."

"My, what deadbeat thing to say. Did you hear that, sister?"

"Yes, truly the words of a loser. I heard him, Rem."

As the voices mocked him, Subaru quickly sat up and looked at the direction where the voice was coming from with a glare.

"Alright! Who are these two voices that keep criticizing me in stereo?!”

two cute maid twins with pink and blue hair posing with each other.

"N-No way… Maid costumes exist in this world too?! Maids were always the very personification of elegance in my mind… “

Subaru looks away from the two and raises his fist in happiness. "This ain't so bad, either!"

"How terrible. You are being violated in the mind of our guest, sister." Rem said.

"It is terrible. It is terrible. You're experiencing the ultimate shame in the mind of our guest, Rem." Ram hugged her sister.

Subaru wiggled his fingers while looking at them with a creepy smirk. "Don't underestimate my capacity. You're both fair prey in my fantasies!”

A gentle knock on the door sounded and made him focus his attention elsewhere.

Emilia was standing in the doorway. "Can't you wake up more peacefully, Subaru?"

Subaru smiles warmly at Emilia. Then he looks at her outfit in surprise.

"Whoever picked that outfit totally gets it!"

"I don't know what you're talking about, but the fact that I know it's something stupid is disappointing.”

“Eh?”

“Hm? What's wrong Emilia?”

She closed her mouth with her hand, wearing a worrying face “Subaru what happened to your eye”.

He sat still, staring at her.

Suddenly his eyes wide open, his pupils shrink.

He turned to the maid.

“Could you bring me a mirror?”

Rem turned to Ram for some sort of signal, Ram nodding “Yes Guest-sama” the blue-haired maid bowed down and walked out the room.

Emilia walked to him “are your eye hurt?”, She bent down to look closer at his eye, then extended her hand to try to touch around the eye, only for Subaru to quickly move away from the hand.

She quickly brought her hand back from Subaru sudden movement “Subaru what wrong?” She asked him with a bit of worry and a disappointed face.

He waved both his hands “nothing nothing!”

And Ram look like she wearing a pretty disgusted face.

“So do you know what happened to your eye?” Emilia asks.

he turned his head away, rubbing back of his head "I have a Theory but this might sound a little bit weird”.

Subaru that process to starts explain about his weird dream.

Emilia can on only giggle awkwardly.

“Guest-sama would you require mental support?” she says softly but her face says the opposite, it looks like she forced her own face to smile and try not to make a disgusted face.

His face turn red “I don't need something like that!”

The sounds of the door click open.

“Ah welcome back rem” ram said.

“Here Guest-sama” she hand him a mirror.

He take mirror from the maid hand“This…” he touches around his eyes.

He stared at the mirror at his own eyes, it was like a shattered mirror, each small piece of the mirror radiating a different shade color from each other.

“It… unique” he move the mirror around looking at his own eyes from different angles “it feels like… watching myself… dozen of them”.

Cut to the two maids 

Rem stare at him, still keep expressionless face while ram sighing.

 

___________________

 

At the garden, Emilia and Subaru are sitting in the gazebo.

Emilia with glowing light floating around her, talking, giggling, while Subaru sitting both of his elbow resting on his leg and both of his hand clamp to each other, making a serious looking face.

‘Follow the star huh?’ 

He closed his eyes and suddenly a ideas pop in his head.

He smiles ‘maybe this could work’

He stood up, bringing his right hand closing his face, and then split his finger where the left eye at, shouting.

“I SHALL  FOLLOW THE STAR!”.

…

 

But nothing happened.

only the sound of Emilia surprised and the small spirit scattered away.

“Ehhaha… Subaru don't surprise me like that” she smile awkwardly. 

Subaru face turned red, he sat back with both of his hands covering his face.

Emilia after the sudden action from Subaru she quickly get closer to him with a worried face, asking and checking if he was alright.

“Subaru! Are you alright?".

Only for Subaru to push her back, while his face still beet red, and quickly said.

“I’m alright!, I'm alright!”.

 

________________

 

 

After a few minutes of Emilia trying to check if Subaru was alright and Subaru pushing her back saying he was alright, she unwillingly backed down from him and went back to talking with the spirit but she still glanced at him from time to time.

Subaru sat calmly thinking ‘Follow the star… what is that supposed to mean!’, he violently rubbed his own hair.

He then sighs and leans back to the pillar, he shut his eyes close, and continues to think.

‘Follow the star…’

After a few seconds pass he heard a sounds of rustle chain.

‘huh?’ 

He opened his eyes, only to find himself standing in the unfamiliar place again.

“No! Not again!” He panically looking around himself, he found himself in a room full of red chairs arranged on both sides of the room in a row with a glass window accompany all the seat at the side, a handrail hanging down from above the seat, the wall painted color red like blood, the floor made out of wood plank.

“I’m on the bus?” Confused, he looks outside the window only to find there is nothing outside there to answer him , only darkness.

He looked back at the room, then noticed a woman… no a hologram of a woman.

even she look transparent he still able see her appearance clearly, she has pale white skin, light blue eyes like an sky color, a shoulder-length white hair, wearing a beige turtleneck with a black leather vest on top, and a large, black leather coat draped over her shoulders reaching her knee, her pants were just simple black business pants and shoes

She stood still staring at him, only after Subaru noticed then she begain to speak.

“Welcome master”.

Chapter 2: Testing power go wrong

Notes:

Literally me after 1000 word later: ah shit i don't know how to continue this

*Look at Subaru*

sorry Subaru I think you have use "it" sooner then I thought

“Welcome, master” a calm voice greeted him.

“To the extracti-”.

“Wait!” Subaru interrupted, raising a hand.

"Just like that!" he said, frustrated. "That's all it took for me to get here, just close my eyes and think of the word, and that's it! Why did I have to do that in front of Emilia?" He scratched his head so hard it seemed he might pull his own hair out.

“Ahem!”. She coughs at her hand.

Only then, Subaru gains his senses back and looks towards the woman.

“Welcome master, to the extraction space”.

Subaru blinked, still trying to process her words. “Uh... right. Extraction Space?”

She spoke calmly, expressionless.

“I am Faust,” She walked towards him.
“Your guide and assistant for utilizing the Extraction Ability.

“And here is your letter from my creator” a letter suddenly appeared out of nowhere into her hand.

“Your creator?”.

“To be precise,” Faust clarified, closing her eyes, “she is not my creator. She merely copied the original Faust to create me.” Opening her eyes again, “And, I somehow know, she’s doing her job very poorly.”

“Uhhh…Ok?” he scratched his head and unsure how to respond to that jab to her own creator.

“So who is the creator you are talking about?”

She opened her eyes and answered him “the one who gave you this ‘Extraction ability’ ”.

“Oh” his memory flashes to the moment of getting punched in the eye.

She handed the letter to him.

He stared at the letter, Even though still a little confused, he accepted the letter with curiosity and didn't bother asking why she, a hologram, was able to hold a letter.

He opened the letter and read it out loud “I’m too lazy to write instructions, so I just gave you an AI assistant instead”.

He looks at the woman then he looks back at the letter.

“if you want to know anything, just ask her” A word appear more on the latter

“Wha- where do these come from!?” he asked, leaning his face closer.

BOOM!

Suddenly the letter exploded in his face.

“Cough Cough Cough, What the?” He turned to the woman, who was now quickly hiding the camera from him by throwing it away.

Subaru makes a deadpan face “you know this is going to happen, right?”.

“No” She answers him, her voice as cold and emotionless as ever.

Subaru stares at her, not believing what she has answered to him.

But willing to put this back to his mind because he wants to try out new power he just received.

“Anyway, how do I use the extraction that your creator has given me?”

Without saying a word she nodded and led him to what seemed like a bus driver area but…there was nothing.

Other than the glass window showing nothing other than endless void of darkness and a simple wooden table placed In the center of the room sat a simple wooden table, and on it, a single item.

Curious, Subaru approached the table, his eyes narrowing at the sight of a plain brown book. Its cover bore two bold letters: “ID”.

“What this?” He picked up the book, “A book?”

Faust walked to his side “it is not just any ordinary book” she said in her usual calm expression.

“this book is where you will keep all identity than you will acquire in the future”

She closed her eyes briefly and said.

“open It, this is the gift my creator have gave you”

“Really!?” excited, he slid both of his thumb into the middle of the book, heart pounding, he slowly opened the book.

…

“Huh?”

Only to find out that it was blank, flipped through them frantically, growing more confused with each turn. “It’s empty”.

She sighs with disappointment, she grabs the book out of his hand, flips the page to the first page and says.

“You were looking at the wrong page”, she handed him back the book.

He laughed awkwardly. “R-right. My bad.”

After that, he shifted his focus back to the book, even though Faust told him which page to look at, the page still looked empty like any other page except that there was a card attached to the left corner of the page.

The card was a portrait of himself.

He carefully picked up the card for a closer look, the card had simple red outlines as its frame and the portrait was him wearing Butler uniform, holding a tray, serving someone, his expression calm and professional, Below the portrait, a name was written:

“Butler of the Mathers Mansion". He read the name.

She grabbed the card from his hand “This identity holds the memory of your life as a butler for the Roswaal L Mathers Mansion”.

“Butler? This me? Is Butler?”.

She nodded “correct”.

His face beams with excitement “Cool! I remember her saying that I can borrow power from my alternate self right? Then this means I could become a Butler? By just using this, right!?”.

“In a way, yes” she handed him back the card.

“You not just simply borrow their power, when you equip the identity, you are them, you will have their body, memory, skills, emotion, habit, desire, even their way of thinking, you will feel like a different person, However, your core self and memories will remain intact”.

Subaru’s excitement turned to a small pout. “Wait a second… If I can get identities, why didn’t I get something cooler, like a knight or something else, as my first one?”

Faust, who seemed to have a very disappointed face, answered him.

“Even a butler's skills can be a foundation for growth, master. Besides, you must work with what you have been given.”

“Fine, fine.” Subaru huffed. “So how do I do this? How do I become the butler? Just shout ‘Go, Butler Power, activate!’ or something?”

“There is no need for such theatrics.” She closed her eyes, “Just simply say the word 'Equip' followed by the identity's name,” she opened her eyes “Or alternatively, using your own will, imagine you holding the card and let it burn on your hand”.

He nodded “okay got it”.

“Now master, I will explain the available functions and a risk that you still need to know…”

Her words faded into the background noise of his thoughts as he stared at the card in his hand, a grin slowly spreading across his face.

“Equip…”

Her eyes wide open, “Master, wait—” her normally calm voice sharpened with an unfamiliar urgency.

She extended her hand, trying to stop him.

“Butler of the Mathers Mansion”

But it was too late.

The moment the words left Subaru’s mouth.

Everything around him cracked, like glass struck by a hammer.

A sharp SHRRRING sound echoed through the void, everything shattered.

 

________________

 

Emilia watched Subaru quietly leaning back against the gazebo’s pillar.
He’d been sleeping for ten minutes now

‘i’m kinda worry about him’

That suddenly the sound of a mirror shatter could be heard.

She startled, standing up, looking around the place frantically, but found nothing weird. She sighs with relief, sits back down.

She heard a yawn besides her.

She turned her head and found a little cat floating beside her cheeks.

“Ah! Good morning Puck, sorry I put you through so much yesterday” she says softly.

“Haaa” the cat now we know his name was puck, stretching himself, then floating towards her plum, sitting there, “Morning, Lia. What was that sound anyway”

She tilted her head “what sound?” She asked.

“You know the glass broken sound”

“oh that… I don't actually know where it co-”

Then she heard a groan, She turned toward Subaru’s direction.

Subaru was slumped forward, clutching his head.

Her eyes widened, even though confused, but she worried more about Subaru.

“Subaru!?” Emilia rushed to him with puck trail behind, kneeling at his side. Her hand landed on his shoulder, panic rising in her voice. “Subaru! Are you alright!?”

His eyes opened.

“Subaru… you eyes it back to normal” hiding her mouth with her hand, and something pokes her attention.

“Subaru…”

He looks towards Emilia, still clutching his head.

“When do you change clothes?” she tilted her head.

Still dazed, “huh? My clothes?” he looked at himself, and froze.

The black pants, The crisp vest, The immaculate tie, The pristine white gloves.

A full butler uniform.

He opened his mouth, trying to speak, only to get interrupted by the sound of someone walking towards them.

“Ah! You two” Emilia look towards them

Rem and Ram bowed down and spoke in sync.

"Emilia-sama. Our lord, Roswaal-sama, has returned."

"Please come inside.” they bring their heads up.

Emilia stands up and walks to them, trying to explain the situation before her to them.

But Subaru did not pay any attention to Emilia, his attention now all focused on Ram, the pink-haired maid, His eyes widened as memories, not his own,flashed through his mind like an old, flickering television.

Memory of him peeling potatoes with her.

Memory of him walking with her after buying supplies from the village.

Memory of him getting scolded by her.

Memory of him holding her lifeless body.

“Ram…” he said under his breath.

He suddenly felt a warmth on his cheeks, he brought his hand up, touched his own cheeks.

He looked at his hand ‘a tear?’.

“Subaru, are you feeling alright?why are you crying?” she walks to him, worrying.

He looked at Emilia and quickly cleaned his tears, and said.

“I’m alright Emilia-sa-” he stops himself ,the honorific almost slipping out like habit. But… it wasn’t his habit.

Emilia tilted her head, Subaru made a small smile, brushed it off and said “it's nothing”.

He stood with perfect posture, calm, refined, and practiced. A butler’s stance, then, wasn't his.

While standing up he catches a glimpse of both the maids, even though their faces look unreadable, but the memory, it tell him what is behind these masks of professionalism.

Rem was suspicious and wary of him like if he made sudden movements he would get killed instantly on the spot.

For Ram, it was not so different from Rem, watching him the way one watches a guest who might, at any moment, become an intruder.
Not brutal, just prepared.

“Please, this way,” Rem said, stepping forward. Ram mirrored her with equal precision as they guided Emilia and Subaru down the stone path, to the Mansion.

 

________________

 

Now inside, Four of them plus one spirit, were walking through the hallway.

Subaru now even though he doesn't want to believe it,His steps were smooth and perfectly spaced, hand on his back, the type of walk than only a Butler then work for many years will have.

But he did not pay attention to how he walked.

‘These memories…’ His eyes caught on the vase sitting on the table, and a strange recollection flashed—him polishing it.

‘So this is what wearing an identity feels like…’ He looked down at his hand, opening and closing his fingers slowly.

‘It's like I'm still myself but not at the same, and you know what strange?, i’m still not on panic at all’

He retracted his hand back to former position.

"If it were normal me, I would already be in panic mode right now”, he exhaled quietly.

Then Emilia glanced back to look at him, he automatically gave her a refined small smile, she smiled back and turned back.

He stopped his smile ‘now then I think about it, why don't ram or especially rem, questioning me about the clothes I'm wearing?’

‘Did the explanation from Emilia make them not suspicious about my clothes? Or did they just keep it to themself? ,not taking any action yet’ He glanced down at his outfit, well-kept, far too clean and proper for someone like him.

‘The clothes it fit me perfectly, it doesn't look weird on me right?, but it feels so natural for me wearing these clothes’.

Then suddenly, another memory flashed through his mind, of him getting taught by ram how to properly wear the uniform.

He fixed his hand collar, still walking, His steps never faltered, because the butler in him wouldn’t allow them to.

As they turned a corner, Rem and Ram split slightly to flank Emilia, subtly positioning themselves between her and Subaru with the kind of natural, calculated fluidity only seasoned maids could pull off. It wasn’t obvious. In fact, a normal Subaru would have missed it completely.

But the “Butler” did not.

‘…They are suspicious. suspicious of me,’ Subaru realized, an odd mixture of calm acceptance and professional awareness threading through his thoughts. ‘They don’t trust me. Not yet. Maybe not at all.’

‘It’s fine,’ he told himself. ‘Judgment from coworkers is normal. Rem and Ram aren’t being hostile, just… cautious.’

‘Wait… coworker? I never worked here’ his mind began to panic ‘i just got here today!’

His heart began to beat faster, but his footsteps remained steady, elegant, disciplined.

‘No, no, no ,this is wrong. I shouldn’t be walking like this. I shouldn’t be this calm. I should be freaking out!, why am I not freaking out!?’.

He felt his chest tighten, but the “butler” part of him smoothed it out instantly.

Subaru clenched his jaw, trying to steady his breathing.

‘This is bad… this is really bad, why am I so calm!? I should be screaming inside! I am screaming inside!’

But his posture didn’t break, His back remained straight, His chin slightly lifted, His steps? , measured, quiet, precise.

Without knowing, he was already standing in front of a large double door.

The dining room.

Subaru stared, His hand was already on the handle.

‘…wait. When did I!? Thought we still had to pass the-’

He didn’t remember walking ahead or accelerating his pace.

He just… arrived.

He glanced behind him. Rem and Ram were still approaching, not far away from him, with Emilia trailing close behind them.

Subaru quickly removed his hand from the door handle, stepping back just enough to look natural.

Rem’s voice broke the silence, she walked up to him.

“Guest-sama.”

Her tone was polite. Too polite. The kind of politeness used when one is interrogating a suspicious stranger without seeming rude.

Subaru straightened instinctively, “Yes, Rem-san?” The honorifics slipped out so smoothly it startled even him.

Rem’s blue eyes narrowed ever so slightly.
“Your clothing… may I ask why you are wearing a butler uniform? Specifically why you are wearing like the one we have”.

Ram stepped forward, arms elegantly folded, expression calm but sharp.

Her rose-red eyes pinned him in place.

“And how did you know the way to the dining room, I remember then we never told you anything about this place”.

Subaru felt something twist in his chest, panic, he frantically tried finding an excuse for him to escape from this situation.

He opened his mouth, try to speak.

A flamboyant, melodic voice echoed through the hallway, “My~~ My~~ I don't remember hiring a new servant here”.

The four of them turned instantly.

Subaru’s breath hitched.

Roswaal L. Mathers stood at the end of the hallway, his heterochromatic eyes shimmering with amusement, his painted smile stretched wider than comfort allowed, He approached with slow, graceful steps.

“Good morning Roswaal-sama” the maids and Subaru bow down and perfectly say in sync.

Subaru eyes widened, Emilia shocked, Puck lazily sitting on Emilia shoulder seemed to not care what was happening here, the maid turned their head to him, Roswaal also shocked too, but it quickly turned into a smile.

‘Why did I bow!? Why did I answer with them!?’
His mind screamed, but his body had already acted on instinct.

Subaru slowly straightened himself, face calm, posture flawless, but inside, he was screaming internally.

Roswaal painted smile lingered on him, stretching just a little too comfortably, like he was observing a curious new toy.

“My, myyy… what an interesting greeting from someone I haven’t had the pleasure of employing~”, His voice was light, playful, but Subaru could feel the weight beneath it, like a thread pulled tight.

Emilia stepped forward quickly, raising her hands, “Roswaal, wait! Subaru didn’t mean any harm. He just-”.

Ram interrupted, still staring at Subaru, “Emilia-sama, forgive me, but Subaru’s behavior is undeniably suspicious.”

Rem nodded, voice quiet but firm, “He appeared in a butler uniform identical to ours. Without our knowledge. Without explanation. And he seems to know the layout of our mansion.”

Subaru swallowed hard.

Roswaal lifted a hand to his chin, humming thoughtfully.

“Ohhh? That is quite a list of coincidences… And I loooove a good mystery~.”

He leaned in toward Subaru, their faces only inches apart.

“Tell me, guest-kun… would you mind explaining how you learned the layout of my home… and why you dressed yourself like one of my servants?”

Subaru froze. The butler identity wanted to give a clean, polished answer. His real mind wanted to scream.

“I-um-I can explain,” Subaru stammered, voice caught between polite formality and absolute panic.

“I, uh… woke up… like this?”

Ram’s eyes narrowed.
“A convenient excuse.”

Rem lowered her stance nearly imperceptibly, Subaru recognized it instantly from the butler’s memories. She was preparing to strike if necessary.

‘WHY DO I KNOW THAT!? STOP KNOWING THINGS!’

Emilia stepped in front of him slightly.
“Wait! Rem, Ram, Subaru wouldn’t lie. He’s just confused. Look, he was sleeping before this happened, maybe his clothes changed because of magic or something!”

Roswaal chuckled lowly, “Magic that changes clothing is not impossible… but rarely does it also grant insider knowledge of a mansion’s layout.”

He tilted his head.

“Unless someone showed him.”

Rem’s gaze sharpened instantly.
“Spy.”

Ram continued, arms folding tighter, “Enemy infiltrator. Perhaps sent by someone targeting Emilia-sama.”

Emilia gasped, “W-wait, not that far!”

Roswaal raised a hand to silence the protests, his smile now thin and unreadable.

“Well then, Subaru-kun…”, His voice dropped, soft and cold.

“Who sent you?”

Subaru’s throat tightened.

“N-no one sent me! I swear! I just woke up and-”

“Lies,” Rem whispered.

“Suspicious,” Ram added.

Roswaal’s eyes gleamed gold and blue, swirling with dangerous curiosity.

“In that case… Until we determine whether you are foe or friend~~”

He snapped his fingers.

Rem stepped forward instantly, aura tense.

Ram mirrored her, crimson eyes glowing faintly.

“…we will have to treat you cautiously.”

Subaru paled.

He lifted his hands, trying desperately to keep his voice steady.

“W-wait! Please! Let me explain! I can prove I’m not a spy!”

Roswaal tilted his head with a smile that did not reach his eyes.

“Ohhh? Then… I do hope you have a very, veeeery good explanation ready, Subaru-kun.”

The tension in the hallway tightened like a wire about to snap.

Subaru lifted both hands slowly, palms open, trying his absolute best to look harmless.

“Okay! O-okay, everyone calm down. Deep breaths. Let’s not jump to conclusions, please!”

Roswaal smiled pleasantly.

Rem and Ram did not.

Emilia shouted.

“Subaru, just tell them! Explain what happened.”

“I-I can’t!” Subaru blurted.

All eyes locked onto him.

‘Crap! WRONG ANSWER! Fix it, Subaru! FIX IT!!’

“I mean-I can explain! Technically! Kind of! But it’s… uh… complicated! Really complicated!”

Ram’s tone turned icy.

“Complicated excuses are still excuses.”

“I’m not making excuses!”

The twins exchanged a look.

Roswaal raised a brow, amused.

Emilia’s voice wavered.

“Subaru… are you sure nothing possessed you?”

“I-I WISH i were possession! At least then I’d have someone to blame!”

Subaru forced himself to breathe, trying again.

“Look… I don’t know why I know the mansion layout. I don’t know why I’m wearing this uniform. I don’t know why my body is acting on its own. I don’t know anything!”.

Ram voice cut through the air like a blade.
“Then you know too little to be trusted.”

Rem stepped forward, “And too much to be ignored.”

Roswaal raised a finger lightly, as if starting a conversation about tea.

“Well, Subaru-kun. It seems you currently stand in the worst possible place in between suspicious and ignorant. Not a pleasant spot~.”

He tilted his head.

“So… any last clarifications before we restrain you?”

Subaru felt the butler’s composure trying to surface again.

He shoved it down with all his will.

“Okay, listen! I had this dream, this vision, this place I got pulled into! There was this woman named Faust, and she said!”

Rem moved first.

“Incoherent rambling. Threat confirmed.”

Her foot slid back. Her body lowered, preparing to lunge.

Roswaal’s smile widened.

Emilia panicked “W-wait!! Rem! Ram! Stop!”.

“Capture him.”

The command echoed through the hall.

Rem lunged, Her speed was inhuman, Her hand extended like a blue blur toward Subaru’s wrist, aiming to restrain him instantly.

But Subaru’s body moved on its own.

He sidestep.

Rem’s fingers sliced empty air.

She froze.

Ram’s eyes widened just a fraction.

“…He evaded Rem?” she whispered.

Subaru stared at his own legs, he wanted to rant about how his body does things on its own but he got no time for that.

He has to focus on what in front of him.

Rem spun, immediate, relentless, A second strike, faster than before, aiming for his throat.

Subaru ducked, sliding backward with immaculate balance.

Rem’s expression darkened, She surged forward again And Subaru’s hand shot out on reflex, fingers closing around her wrist.

Rem stiffened in shock.

His stance lowered And he flipped Rem over his should.

She hit the floor with a heavy THUD.

Emilia gasped, Ram’s eyes went wide, Even Roswaal blinked.

Subaru stares at his own hand, confused, he then looks at rem, that back at his hand.

Rem sprang back to her feet instantly, eyes glowing with fury.

“You dare-!”

Ram stepped in front of her, raising her hand.

“Calm yourself, Rem. It seems our ‘guest’ is far more capable than expected.”

Roswaal clapped lightly.

“My, myyy… Subaru-kun, you’ve been hiding quite the talent. Now I must insist…”

He smiles even wider.

“…don’t die too quickly”

Subaru stepped backward, hands shaking, But his posture remained perfect, ready for any attack.

As Rem and Ram prepared to strike, Subaru’s body was already moving again.

He extended his hand and shouted “Minya!”.

A purple Crystal manifested in the air behind him and shot forward to the maid.

Rem and Ram eyes widened, the maid dodged the attack by jumping backwards.

The purple crystal shattered against the marble floor, frost crawling outward in a spiderweb pattern.

Silence.

For a single, fragile heartbeat, no one moved.

Roswaal’s smile… broke.

Not vanished. Not softened, It sharpened.

“…Min~ya?” he repeated slowly, his voice losing its playful lilt. One mismatched eye widened, the other narrowing with unmistakable intensity, “That is not a spell someone should know about”.

Rem landed lightly from her backward leap, eyes blazing. Ram steadied herself beside her, fingers twitching with magic.

Emilia stared at the frozen floor, with puck still sitting on her shoulder and making a face “Hmmm? Look there's something interesting going here”.

Subaru’s hands shook violently now. His breath came fast, face unreadable.

“You know Subaru-kun,” Roswaal said softly. Far too softly, “Minya is a Yin-attribute spell exclusive to high-tier spirits. More specifically, to Beatrice, the Great Spirit of Yin.”

Roswaal’s voice dropped another octave.

“So tell me, Subaru-kun.”

Step.

He moved closer.

“How does a boy who arrived yesterday… cast a spell only she should possess?”

Subaru’s knees almost buckled.

He screams internally‘I don’t know! I don’t know! I swear I don’t know!’.

But outside he don't answer.

“…I see,” Roswaal murmured, eyes glinting. “No answer, then.”

Rem shifted her footing again, murderous intent no longer hidden, she brought out her weapon.

Ram’s mana flared faintly, red eyes cold and analytical.

Suddenly sounds of the door slamming open could be heard.

Everyone turn to the source of the sound instantly.

“Betty was wondering why you guys take so long to get inside I suppose.”

She stood at the door, arms crossed tightly, brows furrowed in irritation.

“And what happening here, why are guys so noisy out here I suppose”.

Roswaal’s smile froze, just for a fraction of a second.

“Sorry Beatrice-chan, we seem to encounter some little problem over hereeeee”.

Beatrice doesn't seem to care what Roswaal says, she looks around the hallway

Then she spotted it, frozen Minya crystal shards embedded in the floor.

“…Minya?” she repeated, voice dropping, irritation giving way to something far sharper.
She turned slowly toward Roswaal, one eyebrow twitching.

“Why is Minya spell on the floor, I suppose?”

The air tightened.

Rem stiffened.

Ram’s eyes flicked briefly to Roswaal.

Even Emilia went silent.

Roswaal let out a soft, theatrical laugh, waving his hand lightly, “Ohoho~ you noticed already, Beatriceeee. As expected of my adorable little librarian~”.

Beatrice did not look amused.

She stomped one foot forward, arms still crossed, eyes boring into him.

“Don’t dodge the question, Roswaal. Yin mana doesn’t just appear out of nowhere, I suppose. Someone cast it.”

Her gaze slid sideways.

And landed on Subaru.

Her butterfly eyes narrowed.

“…Don’t tell me,” she said slowly, disbelief creeping into her voice, “that this human”

Roswaal’s smile curved wider.

“it came from the boy,” he said pleasantly.

Beatrice eyes widened.

“…It came from him?” her voice echoed, disbelief cracking through her sharp tone.

Her gaze locked fully onto Subaru now, scanning him from head to toe as if trying to peel him apart layer by layer.

“That’s impossible, I suppose,” she snapped. “In 400 years of me staying in the library I have never taught any one that spell I suppose!”.

She pointed at Subaru, and she raised her voice even more “how come then this boy, with a gate of a newborn baby, then I meet in this morning able to use my spell I suppose!”

Subaru opened his mouth.

“I-”

“Silence,” Rem said coldly.

Her chain weapon uncoiled with a metallic whisper, the spiked ball hovering just above the floor.

Subaru’s body reacted instantly, knees bent, weight lowered.

Beatrice stomped forward, stopping only a few steps from Subaru.

“Answer me, human. Who taught you that spell?”

Subaru look at Beatrice, his face twitch a little, then he lower guard

“It, um-it-” his voice cracked.

“ANSWER ME!” She grabs his collar, demanding the answer.

“It… you” His fingers trembled as they slowly unclenched, His shoulders sagged.

Beatrice froze.

Her small hand was still clenched in Subaru’s collar, knuckles white, but her grip loosened just enough to tremble.

“…What did you say, I suppose?”

Subaru swallowed hard. His throat felt tight.

“You,” he repeated, quieter this time. “You taught me”.

The hallway went dead silent.

The maids shocked Rem lower her weapon, ram lower her hand.

Even Roswaal’s ever present smile finally… cracked.

Beatrice’s eyes searched Subaru’s face desperately, as if looking for a punchline, a trick, anything that would make sense.

“That’s not funny,” she snapped, though her voice wavered. “I never taught you anything, I suppose. I barely spoke to you this morning.”

Subaru nodded slowly.

“I know. I know you didn’t, Not… like that.”

Her grip tightened again. “Then explain yourself clearly, I suppose! Don’t speak in riddles!”

Subaru shut his eyes.

And then memories surged.

Not his memories.

Not entirely.

A dim library bathed in yellow lamplight, dust floating in the air like stars, a small spirit sitting on a stack of books, legs swinging impatiently.

“Try Again I suppose” a sharp voice said.

Subaru’s eyes snapped open.

“I’ve seen it,” he whispered. “Your library. The shelves. The smell of old paper. You correcting my posture. Scolding me for wasting mana”.

Beatrice recoiled like she’d been struck.

“That’s-” Her voice broke. “That’s impossible, I suppose.”

Her hand fell from his collar.

she stepped back, looked at her own hand, muttered something that no one could hear.

“Enough.”

Rem’s voice cut through the hallway like a blade.

The air shifted.

Subaru felt it instantly, an oppressive pressure crawling up his spine.

He turned just in time to see Rem straighten fully, her calm shattered, suspicion curdling into something far darker.

“I’ve tolerated this long enough,” Rem said quietly.

Her bangs lifted.

With a sickening crack, a crimson horn erupted from her forehead, mana exploding outward in a violent surge.

Emilia gasped, “R-Rem!? Stop!”.

Ram spun toward her sister, “Rem! control yourself!”

But Rem’s eyes were no longer focused on them.

They were locked on Subaru.

“You’ve tried to deceive us,” she said, voice trembling, not with fear, but fury. “You wear the memories of this place that don't exist, You wield magic you should not possess. You speak of the pasts that never happened”.

“You are a witch cultist aren't you.”

The instant the accusation left her mouth, the air snapped.

“What!? No! I” he don't get time to explain before rem cut him off.

“Shut up!”

She swung her mace towards him.

Subaru barely registered the danger before his body reacted, his body moved his own, pushing Beatrice out of the way of attack, and rolling to the left, barely dodging the incoming attack.

After Dodge the attack, quickly get up to his feet.

Rem didn’t give him time to breathe.

She yanked the chain back with monstrous strength, spinning once, twice, then hurled it again.

Subaru ducked low, rolling forward instinctively. The chain slammed into the floor where he’d been, carving a trench through stone.

He came up on one knee, breathing hard.

“I’m not!” he shouted. “I don’t even know what a witch cultist is!”

“Lies!” Rem roared.

She charged him head-on, abandoning restraint entirely. Each step cracked the floor. Her eyes were wild, overflowing with rage.

Ram appeared in front of Emilia in a flash, one arm outstretched.

“Emilia-sama, stay back.”

“But Subaru!”

“He is no longer safe to approach.”

Rem closed the distance in an instant, swinging the chain in a brutal arc meant to crush his skull.

Subaru raised his arms, and shouted “Minya!”, a purple Crystal covers his arm and blocks the attack with it.

The impact thundered through his bones, shattering all the crystal into pieces, Pain exploded up his arms, but his feet held.

Rem froze.

For a fraction of a second, disbelief cracked her fury.

“…You blocked that?”

Subaru stared at her, eyes wide, shaking.

He didn’t wait for the moment to pass.

He twisted, dash to the chain and yanking it sideways, throwing her balance off just enough. He shoved forward, his fist slamming into her gur, sending her skidding back several meters across the floor.

She gave no time to breathe.

“Huma!” as she shouted, several ice spears form behind her and lunge forward.

Subaru’s vision tunneled.

His body moved before fear could catch up.

He twisted sideways, coat tails snapping as two spears tore past where his head had been. Frost grazed his cheek, Another spear shattered against the wall behind him.

“Guh!”

He rolled, boots skidding across the marble, barely regaining his footing as the temperature in the hall plummeted.

Rem didn’t slow.

She planted her foot, horn blazing, and ripped her arm back, swung her mace downward.

Subaru rolls again barely dodging the attack.

The mace smashed into the marble where Subaru had been.

The impact cratered the floor, shards of stone exploding outward like shrapnel.

Subaru barely had time to gasp before the chain snapped tight again.

Rem yanked.

Subaru’s feet left the ground.

The world spun as the chain wrapped around his leg, wrenching him upside down.

Rem slammed him to the wall.

Subaru back hit the wall hard enough to crack stone, pain detonating through his spine, His vision flashed white, then red, then dimmed at the edges, The chain bit into his leg, tightening like a living thing.

“Guh!” He coughed, blood spraying against the marble, barely holding his own consciousness.

Rem hauled the chain back, lifting Subaru off the ground entirely. He dangled there, body limp for a heartbeat, vision swimming.

She dropping him to the ground, in front of her.

She stare at him, Her eyes burned with fury.

“Any last word”.

He look up smiled, a small, polite, utterly wrong smile.

“Forgive me” he said hoarsely, voice layered his own panic buried beneath borrowed composure.

“But… striking a guest repeatedly without confirmation is… against mansion protocol.”

But look like the word fuel her fury even more.

“DON'T ACT LIKE YOU BELONG HERE YOU WITCH CULTIST!”, she raised her mace up high.

Emilia scream tore through the air.

“REM STOP!”.

Roswaal smile cracked again, his eyes widened, fear of losing something precious.

“Ram stop Rem now!” He shouted, his hand glowing with mana.

Ram after hearing the command, she rushed towards Rem, casting her own spell.

“Fula!”.

After Beatrice stood still and watched the fight for some time, now register what happened.

“Stop! I suppose!” A purple Crystal forms around her “I still need to question him!” she swing her, the crystal lunges forward at rem.

But everyone is too late, none of the spell can reach them in time.

Rem swing the mace down.

THUNK! SPLASH!
