Brainwash The Insect Pillar | Shinobu x Female Reader | Demon Slayer

This idea is from; PillowWillowTree

Can you do a Shinobu (demon slayer) x female demon reader angst where the reader was assigned by Muzan to kidnap and brainwash the insect pillar to make her Muzan's loyal and obedient servant to help defeat the other pillars but during the process, the reader feels awful for having to put Shinobu through so much pain during Shinobu's brainwashing that reader refuses to do anymore and tries to escape with Shinobu to try and get her back to the other pillars?

Just going to say ahead of time, this will most likely have inaccurate information towards the original storyline. But I'm going to try my best to at least have it similar to the original storyline. Enjoy!

I silently appear behind the insect demon slayer, I grab her sword throwing it behind me. She swiftly turns round to my hand at her forehead, her already wide purple eyes widen as she sees me. I flick her forehead sending her into slumber, I catch her before she falls. 

I carry her bridal style as Muzan appears from the darkness of the alleyway behind me. "Well, done," he says while picking up the insect's sword. He throws it at me and it lands on the girl, I look up at Muzan as he turns around. "Get moving, I don't have all day," Muzan says making me follow him instantly.

I follow him into the dark to only end up into a room, I'm use to this by now so I just take my sandals off and walk into the room. I lay the insect girl on the ground, I hear Muzan walk over to me. I stay quiet awaiting my orders on what to do with her, "Y/N, when she awakens change her thoughts. Get into her head and destroy all of her memories only leaving her to the ability to speak and follow my orders," Muzan says as he towers over me from behind.

"Sir, this could take days," I tell him politely. He steps on my head forcing me to the ground, I feel the slow drips of blood from my head but it heals in a matter of seconds. He then proceeds to kick me, I get kicked into the wall feeling a small crack go through my spine.

Muzan walks over to me, he looks down at me, "I don't care how long it takes as long as it's done," he says. He leaves the room and locks it behind him, I groan as the crack in my spine slowly heals. I stand up and walk over to the insect girl, I move her hair out of her face.

Her features are remarkable, she very... beautiful. I sit down in front of her and examine her body, she doesn't look very strong. I look over at her sword, I get up and grab it. I sit down in front of her once again, I open the sleeve of the sword. I take the sword out and examine it, this is an odd sword. How is it suppose to cut our heads off? 

I put the sword away and place it behind me, she doesn't look very tall either. Her haori has a beautiful butterfly pattern on it with turquoise fading into pink at the bottom. No wonder she's the insect pillar, her sword is like a bee's stinger, her eyes symbolize an insect's, and her clothing shows the beauty of a butterfly.

I see her purple eyes flutter open to meet my demonic eyes, I look away in shame as she sits up. I look back at her, she doesn't appear to be fighting back. "Your name?" I ask as her purple eyes burn into my skin.

"Shinobu... Kocho, yours?" she spoke with a light feathery voice.

"Y/L/N Y/N," I respond. I get closer to her, our knees close to touching. I gently place my hands on both sides of her head and moving my thumbs to her temples, she looks at me with her purple eyes. Why must I do this?

"What are you doing?" she asks not moving a muscle.

"Sorry," I say before I begin the brainwashing. Her screams penetrate my ears making me want to cry, I hate doing this. I watch the tears stream down from her beautiful purple eyes, I look away from her. Why... why do I do this?
