Sabito's Little Sister

Awakening

"She's had a lot of the Wysteria Poison." Yushiro stressed while giving you multiple injections, though the lavender colour in your veins didn't cease. "I'm trying to turn her back into a human before she gets--"

Yushiro looked over at the.. crowd of people standing in the hospital wing of the Butterfly Mansion. "Never mind. The point is that you should leave so I can properly concentra--" He was cut off by a struggled gasp, and all eyes turned to you.

"Yushiro-kun, please update us." Mitsuri pleaded.

Most of those who were able left the hospital wing, leaving only Tanjiro, Zenitsu, Nezuko, and Inosuke. Tanjiro looked longingly at you, and guess who that was making uncomfortable.

"Oi, moron Demon Slayer. When you stare at her, you realize you're staring at me as well?"

"Ah! Sorry!"

Yushiro shook his head and continued tending to you, trying to figure out what Miss Tamayo would do in this situation.

He paused, right over your slightly balled up hand, reaching into his pocket and pulling out the hairpiece you found. What would Miss Tamayo do in this situation? Why did he feel so... lost?

You twitched a little and furrowed your brow, a bit like you were having a nightmare.

He sighed and leaned back on the wall.

"Yushiro-kun, are you alright?"

Yushiro flinched and looked down at you, seeing your eyes still closed and your figure still motionless. Right... she needs to wake up. Desperately.

He worked late into the night, ever so often hearing your breathing get heavy and injecting a perilously large amount of medicine into your veins. All the while, Tanjiro watched.

Yushiro finally gave a defeated sigh and moved back. "I've tried everything, so all that you can really do is wait. I will send a crow to the Hashira."

Tanjiro nodded and Yushiro left the room, the curtains finally being able to be drawn, though it was already late at night.

He looked over at you, seeing the dull purple hue crawling down your cheeks and up your neck like a plague. It was definitely less noticeable, but he could see it so clearly while you were being illuminated by the moonlight.

Slowly, he pushed off his blanket, slowly removing his legs from under Nezuko's head and walked over to your bed. He sat at the end and looked at you.

He never actually took the time to look at you before... you were beautiful. With your hair perfectly spread across the bedsheets and your hands neatly folded over your stomach and blanket.

But most of all, he loved your gentle expression on your face. It was better than the seeing your cry, your eyes widen in horror, your face go blank once your tears dry. It was better when you were calm, smiling, gentle.

Tanjiro placed his hand over yours, his eyes softening.

"Y/N... please... please, wake up. We all need you here. And it may sound cliche but I need you here. More than anything. You were always next to me, no matter what form. Even when I was in the midst of killing you..."

He paused, his vision blurring.

"Please, I want to see you smile again. It's not the same to see other people's smiles. I want yours... so please, open your eyes."

He sighed and looked down at his hand, right over yours. He intertwined your fingers and shut his eyes. Please gods... please save Y/N.

Finally, he let go of your hand and went back to his bed, reluctantly falling asleep.

Many things happened over the next few days.

Between the final Hashira meeting and Inosuke trying to steal food from the kitchen, it wasn't all that eventful if you compared it to what the daily was before.

One day, almost everyone gathered at the Butterfly Mansion, some to check on you, some to just visit, but it ended up turning into a large picnic in the yard.

"Inosuke, there's food right here! Why are you trying to pick up the ants?" Aoi scolded, grabbing the boy's wrist.

"Say ah!" Mitsuri held chopsticks with some udon at the end near Obanai, which he took, as well as Kabumaramu.

"Y/N still isn't awake?" Sumi asked Tanjiro. Tanjiro solemnly shook his head and looked at his food. "But she'd nag me heavily if I let that weigh on me."

There were multiple Kakushi in your room, tending to you, when you mumbled something incomprehensible at first, but then you mumbled the same thing, this time a bit louder. "T-Tanjiro...!"

"Onii-chan!" You exclaimed, jumping into his arms. "Hey, Y/N! We're heading out with the some other Demon Slayers to do some training. Want to come?"

You looked behind him, seeing Muichiro, Genya, Shinobu, and Rengoku. "Yeah s—" You paused and stepped back.

"Wait, where... where am I? Onii-chan, you don't know who the Hashira is... and you guys, you're... you're dead!"

"Did you hear that?" Zenitsu questioned, looking up from his food.

"Hear what?"

"Was that... Y/N?"

Tanjiro immediately stood up and ran to the hospital wing.
