These are humans...? (Yandere KNY X OC Reader)

Cutting The Boulder

Lynn's pov

  To say I was worried would be an over statement. I didn't allow myself to care much. However, I did take notice to how hard Tanjiro trained. Once it turned to be a months before final selection; I suppose Tanjiro realized this was NOT a game. And that if he did not cut the rock. I would go on to become a demon slayer without him.

  He had begun to train as hard as he could. He was now training as hard as I was. However, he focused on his physical training, meanwhile I focused on my forms. I had mastered all but the first form. I was still struggling to preform it. It was by far the hardest form. I had spent weeks on it, and I only managed to land one successful attack.

  I was once again reading into every detail I could about how to preform it. Doing it slowly, then actually putting the form into motion. It wasn't that I would fumble, I wouldn't trip up or anything like that. However, the effects of the sun were hard to maintain throughout the full attack. I did notice how the blade turned different colors depending on the move. The one successful attack I made, my blade turned black. The two easiest for me were the water and the moon. Since, I had always had a strong connection with the moon, Since it powered my 'final form'.

  I leapt up into the air and muttered, "Elemental breathing: First Form: Suns Wrath." With that said I launched forward at the attack dummy. A white, pink, red, and orange effect leaving my sword in a trail. My sword was engulfed in the flame like attack. It was beautiful, but I refused to allow myself to be distracted.

As I landed on the dummy's stomach, I aimed for their neck, cutting it clean off. Unfortunately though, the effects only lasted until then, and almost immediately vanished after the neck was breached. 'Disappointing, but at least a managed to cut their head off.' It was certainly an improvement, but I needed to master this move. After all, it is the most important and powerful one of them all.

Tanjiro's pov

4 weeks later, i didn't know this, but everything was about to change. Once more, i had challenged him to a doul, but this time, he had a real sword with him. "It took you 4 weeks, but you finally look like a man." He drew his sword out. Preparing himself in a fighting stance. I had already done both. Makomo stood on the side but in between us, watching the fight.

'A fight like this is simple, whoever is faster and stronger wins. I just hope... that that will be me. Because, if it's not, I won't be going to the final selection with Lynn, and what if something were to happen to her? I'd never be able to forgive myself.' I drew in one last deep breathe before the fight. As soon as the breath is drawn in, we're both on the attack.

As if we teleported, we rushed toward each other. Our swords raged high above our heads. It was over in an instant. For the first time, my sword came down first. It scraped the dirt as a result. My sword had cut perfectly through the mask. Slicing it into two perfect half's, his mask fell apart. Revealing I soft smile, 'this is not the same guy I had fought all this time. Has it been?' He was always so cruel with his comments after and during fights. But seeing his face and his soft smile made me change my mind of his cruel intentions.

He held the same scar was present in the same spot as it was on the mask. He had deep yet slightly dull, gray-ish blue eyes. That seemed to hold no grudge but happy, except he had a lingering sadness on his face. The mask hung from his neck by a red rope that he used to fasten it to his face.

"Tanjiro..." I heard Makomo's soft voice and turned my head to look at her. She was smiling at me as well. "You did well Tanjiro. Never forget this. And never forget us." I was confused why what she meant. When suddenly the fog rolled in, slowly her face disappeared with it. "Keep winning for us Tanjiro. The next time too." She was then gone. I looked back to see Sabito was gone as well, the fog thick all around. I could hardly see a foot ahead of me.

But when the fog did clear. The rack was ahead of me, and it was cut. 'I'm sure what I cut through was Sabitos mask, was it?' I wasn't sure anymore. All I knew was that I had done it. 'I have cut the rock.'
