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

Sabito and Makomo

Tanjiro's pov

It was just another day of me trying to cut the rock. 'Am I really this worthless?' I thought dropping my sword to the ground. Exposing my scraps to the world. "Keep training, Tanjiro!!" I banged my head against the boulder. "Train harder!!" I banged my head agiain. "Silence!" A voice sounded from above the rock.

  When I looked up, I was shocked to be meet with a boy that seems to be around my age. He had peach hair that reached their shoulders. They adorned black pants and a white haori. They wore a mask over their face that resembled a fox, but it had a scar on the his right cheek.

  "A man shouldn't wine, it's unseemly. The girl never once wined or complained." He said, mentioning Lynn. 'When did he show up?' I questioned, staring up at him. 'There's no scent. And the fox mask reminds me of Lynn's own mask.' "No matter how much you suffer, bear it in silence." He interrupted my thoughts.

He stands up. I notice he holds a wooden sword. "If you're a man," he continues. I suddenly jumps forward toward me, "if you call yourself a man." His sword clashed with mine before he kicked me in the stomach. Pushing me a few feet away. I fumble before regaining my footing.

"Slow. Weak. Immature." He continues on his train of insults. "That's not what you call a man." His hair waved in the wind. "What are you doing?" I asked him. "I'd lime to know what you think you're doing." He replied, 'his messages are so enigmatic, he makes no sense.'

"What do you mean? I'm training." I replied, confusion prominent in my voice. "How long do you plan on standing there like an idiot? Without even taking a stance?" I realized, 'I really am just standing here like an idiot.' I immediately prepared myself in a stance.

"Come on, come at me." He prompted me to came forward with an attack. Motioning me with his fingers. I was shocked. "But you have a wooden sword, and I have a real one!" He threw his head down, staring at the ground. He awoke retracted his arm. Before laughing maniacally; all the while turning his head up to look at me.

"Well, well! Thank you for worrying about me." He inquired, confusing me greatly. "So, you think you can hurt me?" Clearly trying to challenge me. He suddenly dashed towards me. I stumbled and hardly managed to block his attempts at hitting me with his sword. "Well, you have nothing to worry about. I'm more powerful than you..." he gloated; meanwhile, I struggled to keep him back. 'I'm not in a good position. "I've sliced that boulder!" 'He's sliced that boulder?' I tried to keep my shock off of my face.

He jumped up, flipping through the air. Behind me, I heard him bounce off of a tree. I turned around as he was diving towards me at fast speed. My reaction time was just quick enough to knock him a few feet away from me. He began speeding around, treading through the ground, bouncing off trees as he went. Suddenly, he rushed right past my ear. Catching me completely off guard. That was the last thing I saw, before being knocked to the ground. 'My body hurts from the impact.'

  "You've learned nothing. You have not mastered a single thing!" He stated from above me. Staring down at me as I lay on the ground. "Certainly, not the breathing styles Utokodaki-San taught you! Total concentration breathing..." I was struggling to get up as I thought, 'he knows Urokodaki-San? Who is he?' "That girl, Lynn, was it? She is more of a man than you ever will be!"

"All you have done with your training, is memorized the information. Your body has no idea what it needs to do!" He ranted on with his insults. "What the h3ll have you been up to for the past few months? All of it should be hammered into your flesh!" He yelled aloud, as he lunged forward, sword in hand, and attacked me vigorously.

"So that you'll never forget any of the secrets Urokodaki taught you!" I finally managed to jump away from him, before he split my head open with his next attack. "I'm trying! I'm trying every single day! With everything I've got!" I was now getting irritated. 'But, it's not enough.' I voiced out in my head.
