10.

|| Guys I'm so so so sorry this took forever!! I'm getting bombarded with exams and task sheets (ALREADY) and on top of that I had this written a bit ago but I didn't like it so I decided to re write it. Again, so sorry :( ||

Muzan walked into the dark room, seeing Tanjiro curled into a ball on his bed, sheets everywhere but on him. He smiled and chuckled to himself.
He stared a moment longer and took a deep breath in, reaching for the vile of his blood.

He didnt want to ruin Tanjiros peace.

He quietly walked over to the boy, knowing as much as a mere creak of the floorboards wouldnt wake him anyway.
Muzan rolled up his black sleeves and popped open the vile, moving his other hand towards Tanjiros face.

As carefully as he could, he opened Tanjiros mouth with his thumb and put the vile up to his lips. He tilted it slowly, then just before the blood could enter his mouth, Tanjiros lips flinched a little.

Muzan instantly pulled back his hands, standing back to see what happened.

Is he awake..? Did it not work?

He came to the conclusion he was asleep. Muzan stared for a while longer and moved closer again, extra carefully this time.

He tipped the vile one again, but hesitated.
Muzan took a deep breath and tipped the vile in in one go, making sure he got every last drop. The seccond it was emptied he pulled it away and closed Tanjiros mouth.

He turned around and walked a few steps back to give him some space. He noticed the sheets on the floor and hastily grabbed it, throwing it over Tanjiro.

Basically moments after Muzan closed Tanjiros mouth, the boys muscles started to spasm and twitch. Then it became more violent- like his whole body was screaming and shaking.

Normally, Muzan would care since he'd seen this so many times. But Muzan blinked slowly and turned to the corner of the room where he now stood. He couldnt watch.

Tanjiros body started to contract as the blood was slowly ingested, and he was now sprawled out over the bed in an uncomfortable way.

Unfortunatley, Muzan had to stay and watch to make sure the transformation was completed properly.
By far, it was the most painful hours of his existence.

All he could do was stand and try not to watch as his boy tossed and turned, writhing in pain. Muzan hoped that the dosage he gave Tanjiro really worked, and he was asleep and not just unable to consciously move or react.

Eventually, the spasms and the horrible, seizure-worthy shaking was over, meaning the transformation was complete. Tanjiro had returned back to a curled up ball, like almost nothing had changed. Despite the blankets on the floor in shreds. Or the pillows thrown across the room.

Almost nothing had changed-

Except Tanjiro.

|| large time skip, didn't need the extra chapters for nothing. ||

"Alright, that one wasn't too bad!" He complimented, walking over to the panting boy and placing a confirming hand on his shoulder.
