"Alright dad. Ill become a demon."

---------------------☆

Muzans eyes widened in surpise.

"You mean it?"

Tanjiro nodded instantly.

"If it helps you achieve your dream, father! Ill do anything to help you! Afterall, i owe you my life. Its really the least i can do."

Muzan couldnt hold back the wide smile now plastered on his face. He fell to his knees - to Tanjiros level - and pulled the kid in for a short while.

Embarrassed, Muzan stood back up in a matter of secconds and cleared his throat.

"Uh, sorry. That was uncalled for." He defended, instead ruffling Tanjiros auburn hair.

Tanjiro didnt respond, he remained still and dazed. The corners of his mouth twitched up into a small smile.

"No, its okay. Thank you, dad." He quietly responded, fiddling with his hands.

"So...about becoming a demon and all of that." Muzan finally broke the awkward silence.

"Yeah, i know. I was about to ask about the details. How do i become one?"

Muzan didnt wait to respond.
"You become a demon by ingesting another demons blood. Based on how strong that demon is and how much blood was taken, the time and pain level of the transformation can alter. As well as your own power level."

"...pain level?" Tanjiro squeaked, tensing up.

Muzan grew worried.
Will this change his mind? He said he'd do it for me. I dont take this kid for a liar.

He hesitated before nodding.

"It wont be much. Most of the time you pass out before the change and pain even take place. Ill make sure you wont feel anything, dont worry."

Tanjiro felt reassured by Muzans words. He sighed, relieved. Tanjiro let his shoulders droop and thanked him.

"Of course, i wouldnt let you get hurt. Ever. Especially by my hands."

|| Later that day. ||

Tanjiro was sitting on his bed, hunched over in a usually uncomfortably position. Between his lap, he had a old dusty book flipped to the last page. Days at the Infinity Castle were slow and boring, so Muzan had searched through his massive library for a some-what kid appropriate book. In the end, he found a 'basics of chemistry' book. He was reluctant at first but Tanjro persisted; "A book is a Book."

And so Tanjiro finished the last page. He couldnt tell if he was bored or not, but his eyes felt dry and strained. He closed the book with a dramatic slam. Dust particles flew off the cover, causing him to sneeze.

Tanjiro groaned, allowing hmself to fall on his back. He closed his eyes for a seccond, wishing for sleep.

Although there was no windows here, Tanjiro could tell it was growing dark outside. If it werent for the fact he hadnt eaten yet, he would be dead asleep. He had no more use for this day- nothing life changing is going to happen.

wait.

Tanjiro sat up instantly, eyes shining.

Right! How could i forget? Fathers turning me into a Demon tonight..!

Tanjiro visibly saddened, the shine from before now fading.

Maybe Father forgot. He does have alot on his hands, being in his office 24/7. Father is a busy man. I cant blame him- but he did seem very eager to turn me earlier.
