The son of the Devil (KnY)

Chapter 2: Staying true to ones self

As Muzan slowly led Tanjirou away from the life he once knew he began to think of Nezuko and how she would fell about all of this. Will she be okay? He thought. I really hope so.

"So Muzan where are we going exactly, we have been walking for hours."

"Oh, you will see very soon my boy, very soon." He said.

Just then a house came up in the distance. It was a small house that looked barely bigger than the one Tanjirou used to call home. Muzan led Tanjirou into the house and brought him to an empty room. Muzan then sat him down on the floor in the center.

"Oh, my boy Tanjirou I truly believe you will be able to survive the amount of blood I am about to give you." Muzan said smirkingly

" I know I can so don't worry about it. I will survive for Nezuko!"

Just as Tanjirou finished his sentence a demonic tail like limb shot out of Muzan hand and stabbed Tanjirou in the middle of the stomach. Tanjirou then began to enter a fit of coughing up blood. Tanjirou strained and cringed as he tried to hold on to his life. Not succumbing to the pain.  Tanjirou's cries continued for about 5 minutes nonstop. Muzan finally took the tail out of Tanjirou and said.

"There you go my sweet little Tanjirou."

Tanjirou's only response was cries of pain. But on the inside, he liked the sensation of power that had overflowed within him. He cried to Muzan to give him more and Muzan reluctantly agreed. Tanjirou was not crying this time but silently suffering as the pain coursed through him but yet, the power that he felt made it all worth it in the end. 

Another 5 minutes passed and Muzan finally said that it was his limit of blood giving for a day. Tanjirou did, however, convince him of giving him 3 minutes' worth of blood each day. 

"Tanjirou my boy," Muzan said. "that is the most amount of my blood any demon has been able to withstand. You truly are something special...                   now come and follow me, my boy, if you wish to gain more power."

"Of course Muzan." Tanjirou said as he willingly followed Muzan.

Muzan then led him to the Upper 6 Moons of the Twelve Kizuki. Which Tanjirou took a minute's worth of their blood each. 

"My, my Muzan are you trying to make a demon strong enough to rival us." Said Upper 5 smirkingly.

"No, no I would never" Said Muzan. " But I do need something for you guys to fear in a sense."

Tanjirou then proceeded to train with the Upper Moons till sunrise. Tanjirou had still not developed his blood demon art. And yet he was able to beat Upper 6 and Upper 5. Did not fight Upper 4. And finally lost to Upper Moons 3, 2, and 1.

"You did well young one." Commented Upper 1.

"I like you, you aren't weak like most others." Said Upper 3.

"Now then Tanjirou allow me to show you to your room." Said Muzan. "Upper 2 decided to decorate it for you after doing so well in your fight."

"Tell him thanks for me."

"Will do." Said Muzan as he left the room.

Tanjirou started to cry after the door shut. What... He thought. How stupid am I. Why in the world was I so desperate for power. Why did I willingly accept to become more demonic?' He asked himself. At least I can retain my promise to never eat humans. He then thought. I will be okay with myself. But what I just was that was not me. And now, all I can do now is hope that that won't become me.
