That Butler, Isekaid (Modern!Reader Insert)

That Butler; Static

"Ehe... Um..."

Ciel's eyes narrow as he observes ____'s sudden outburst and the tension in the air. "_____, it seems you possess knowledge that is beyond the realm of ordinary humans. How do you know of Sebastian's true nature and the concept of demons and hell?"

You try to compose yourself, your grip on your phone tightening. "Oh, um, you know, just a lucky guess? It's not like I know anything about demons or hell or anything. Just a wild stab in the dark, that's all." ____ offers a forced smile, trying to brush off their little slip-up.

Ciel's gaze intensifies, his voice dropping an octave. "_____, do not think for a moment that you can deceive me. Your reaction suggests otherwise. Tell me the truth."

_____ gulps audibly, realizing that their attempt at denial has failed.
"Okay, okay... You got me. I know more than I let on. But I promise I mean no harm! I- I just..."

Ciel's voice is low and laced with suspicion now. "Sebastian, did you reveal your true nature to this... individual?"

Sebastian, ever the picture of composure, maintains a calm facade. "No, my lord. I assure you, I have not divulged any information nor revealed any secrets. This individual's knowledge could only be based on speculation or mere coincidence."

"_____" He begins, his voice icy and measured. "Speak. Do you have something else you would like to share with us? I find it rather intriguing that you would use such a term to refer to Sebastian. It's not a common knowledge that he is, in fact, a demon."

Sebastian, ever the master of intrigue, speaks up as well, his voice laced with curiosity. "Indeed. It seems you possess knowledge beyond what should be available to you. How is it that you are aware of my true nature?"

______'s heart pounds in their chest as _____ realizes the mistake they have made. Panic begins to rise within them, but they quickly compose themself, their expression shifting from nervous laughter to avoidant looks elsewhere. Ciel's gaze remains locked with yours, sharp and piercing. "Do not dissemble, ____. I can see through your feeble attempts at deception. You possess knowledge that should not be available to you. Tell me, who are you and how do you know about Sebastian?"

_____ takes a deep breath, contemplating their next move. The truth was too dangerous to reveal, but lying to Ciel Phantomhive was a treacherous path.

"Well, let's just say this whole thing... I mean- Beings like demons are... An anomaly and fairytale-like kinda thing..?" _____ responds, their voice, cryptic. "It's amazing what stories and legends can tell us about the supernatural, isn't it? It's all part of the charm of the unknown- heh."

Ciel's eyes narrow even further, his suspicion growing with every passing moment. "It seems you are attempting to avoid answering my question, _______" Ciel states, his tone colder than ever. "I warn you, any further attempts at obfuscation will not end well for you."

_____'s heart races as they look at Ciel and Sebastian, both of them exuding an aura of danger and power. They considers their options, knowing that lying could have dire consequences, but revealing the truth could be even worse. Ciel stands from his seat in his study, staring at _____. Before he looks over at Sebastian who in turn is also looking straight at their 'guest' with apprehension and with already prepared weapons in his grasp

"WOAH WOAH WOAH!!! I HAVE NO PLANS TO BECOME SHISH KEBAB YET! PUT THE BUTTER KNIVES AWAAAAY!!!" _____ screams scrambling to the nearest corner clutching their phone for dear life like it's gonna save them somehow.

"Sebastian, are they..?" Ciel's voice trails off, watching the individual tremble as _____ looks up at them.

"They are not young master. However, they might know more than they're allowing themselves to speak.." Sebastian steps away from _____ a bit, allowing his young master to do the interrogating. Welp, you really screwed up with that one...

Ciel narrows his eyes at _____, his gaze piercing and calculating. "You seem to know more than you're letting on. How did you come to learn about Sebastian being a demon? Are you associated with any supernatural entities? Speak, and speak the truth, or else you'll face the consequences."

_____'s heart pounds in their chest even harder as they look up at Ciel, voice trembling. "I- I just... I already knew from the start he was a demon..."

Ciel's skepticism is evident as he studies ______'s fearful expression. "From the start? Do you have knowledge from the future about us of some kind? I demand an explanation."

The (hair color) (gender??) swallows hard, their mind racing to come up with a plausible excuse, unfortunately finding none. "Uh, well, you see... I just- There's books okay! Books of demons and such, that uh... Make contracts with humans and all that. The book I read before I got here, is like- Your guys's history! History and records of the past, and whatever!"

Ciel's glare intensifies, his suspicion growing with each passing second. "Books, you say? Which books? And who would dare to speak of such things? I want names and titles."

____ fumbles for an answer, their mind racing for any possible solution to get out of this predicament. "I- I can't tell you everything you want to know! It'll turn out badly, and it could ruin the world as we know it! Futures and pasts and such aren't supposed to mix or even be known by those involved!! Please don't make me speak, I don't want to destroy a world or end any lives..!"

Ciel's eyes narrow further, his tone becoming colder. "What? What do you mean? _____, I have no patience for your games. Explain yourself, or face the consequences."

_____'s voice shakes as they speak, eyes darting between Ciel and Sebastian, their fear palpable. "I- I can't, I'm sorry! It's complicated, and if I reveal too much, it could have disastrous consequences for everyone involved. You have to trust me on this."

Ciel's expression turns stony, his patience wearing thin. "Trust you? You expect me to trust someone who withholds vital information from us? Your words hold no weight, _____."

Sebastian's voice cuts through the tension, his tone calm and calculating. "My lord, perhaps it would be wise to consider their words. There are forces at play that we may not yet understand."

Ciel glances at Sebastian, his eyes filled with a mix of frustration and curiosity. "Very well, Sebastian. I shall hear them out for now, but make no mistake, _____. My trust can be easily broken."

_____ lets out a shaky breath, grateful for the reprieve. "Thank you... I understand your skepticism, but revealing too much too soon could have dire consequences. Just know that the influence of any rift within times and the like, cannot be underestimated."

Ciel gazes at ____ for a few more seconds before finally sighing. "Very well. For now, we shall trust in your judgement, _____. But know that we shall be watching, and any deception will not be taken lightly."

"Understood..." ______ nods, a mixture of relief and apprehension flooding through them "I understand. I have no intention of betraying you or your trust. I just wanna find a way back home"

Ciel's gaze softens slightly, a glimmer of understanding in his eyes. "Very well, _______. Let it be known that you are under my supervision. You shall assist me in any way possible, using your knowledge and abilities to aid in our endeavors. However, one misstep, and our alliance will crumble."

"Yessir.."
