OC x Rengoku Kyojuro [REMAKE]- "Thankful for you "

Chapter 2.

I've never understood why my mom has been so cold with me during most of the day. The only time she talked to me was during dinner and when she'd help me figure out the chemical reactions of the serums. My father used to tell me how he fell in love with her and how she was one of the most stunning women he'd ever met. I never understood their relationship. To be fair, I've never understood love. My sister was the opposite. As time went by and as we got older she fell in love with a boy in town. She was allowed to go out and have fun during festivals, and I wasn't. I never got the chance to meet people and fall in love just like my sister. I was disappointed. Even if I tried to run away on my own I would get caught and get told off by my mom. I have to listen to my mom, she's always right. I can't speak over her, she knows better than me. I quickly created my serums and wrote my recipes down by the age of 14. I've encountered with the flaming boy a few times until he completely disappeared. He said he wanted to become a Demon Sayer so it's likely that he went to Final Selection and started training more seriously. My sister was 19 and the boy she loved was her fiancé. Whenever he came by at our house I'd have to hide outside or in my room to either train or study.

It was stressful to keep myself a secret from society. My mother said it benefited her whenever I would get caught doing a crime. Why would I do that either way? It's ridiculous! But, everything took a turn for the worse. My whole life was about to change within the following months. I still blame myself and I still remind myself of the accident. I will never forget that evening.

One fateful night, I was sitting and meditating on the porch with my mother. Our sister had gone out with her fiancé at the festival. My mother was optimistic, hoping my sister would come back unharmed. That wasn't the case. As soon as the fireworks set off with a loud bang the old woman sensed something from the forest, coming up to us, moving quickly. I had no time to react as she grabbed me and pushed me inside the house together with her. She coughed, weakly throwing her sword near me.
"It's a demon. It's going to attack, I can't fight back."

I quickly grab the sword and sit upon my feet, anxiously shaking, keeping my stance. The smell was foul but familiar. It was tainted with evil. Everything flashed before my eyes as the figure rose from the darkness of the forest and pounced inside our house, breaking down the doors and tumbling over inside, ruining the rugs and floor. The sound of its nails digging into the wooden floor made my ears twitch. After I get a good look at the demon I completely stop. My heart drops. It was my sister.

"Tsumiki, what happened to you?"
I cry out as I try to reach out to her. She attacks, but I dodge. She's slow. I can sense a stinging smell coming from her. Blood was dripping from the corners of her mouth. She killed her fiancé most likely. So there was a demon attack? What happened? She attacks again. I can't bring myself to hurting her. She's my sister. My only friend. My light. I hesitate. I felt like a complete coward. This hesitation leads me to getting attacked full-on by her. She latched on to my shoulder with one of her hands and pushed me to the ground. Her free hand slashed me across my face.

Blood gushed out and I screamed in pain and boiling anger. Something in me triggered. Tears fell down my cheeks as I peeked over at my mom trying to get up and help me. She was so weak she could barely help herself up. I look at my sister straight in the eyes but my overflowing tears fogged my vision. I grabbed her neck with one of my hands and threw her away from me. I run up to my sword and get back up on my feet. She gets ready to attack. I get ready to do what has to be done. She jumps up over me. I let out a final cry. I hitch my breathing and close my eyes.
"Breath of Harmony. Second Form: Silenced Dance of Peace."

I open my eyes and turn around. I had slashed right through her neck. I wipe my tears and blood, but they kept coming. They never stopped flowing over my face. My haori was filled with blood. The foul smell was starting to go away. Me and my mother watch as the corpse of my sister dissolves into the air.
"Oh, my child. I'm so sorry."
My mother cries as she reaches out to her remaining body parts. I drop on my knees and cry. I cry. I mourn. I've killed the only person that I've considered a friend these past 14 years of my existence. It's all my fault. Her body disappeared. She was gone. My mother calls out for me and screams for my father. He barges in and drops the book he was holding. He screams in shock. His screams turned into sobs as he realized what was going on. My mother had to sit him down as she tried to tend to my wounds and explain to him what had happened. His face dropped and looked over at me.

He was heartbroken, I could tell. My eyes felt heavy, and the last thing I remember is my mother cursing under her breath and carefully wiping all the blood off my face. I wake up the next morning. I couldn't feel my face, it was covered in bandages. My mother came and sighed heavily. Her eyes were red and puffy. She cried all night.

"Your father is out on a walk. He needs some time to think. I, on the other hand. I'm here to tell you the truth."
Was she saying the truth?
"Don't try to speak. Your bandages are stopping you from doing so. Just listen."
I nod my head and turn to face her.
"This is all the Demon Slayer Corps fault. I know this because there wouldn't be a demon attack in our town out of nowhere. Trust me! They let out some demons roam freely around our village to taunt me and challenge me to take them down! They've told me to stop all demon slaying activity, so they sent in an army of them. And they infected my daughter."
I stop. My heart drops. I think, and I try to make something out of my mother's words. This sounds far-fetched but, it is a possibility. They did this. It is all their fault. It's THEIR fault. They made me kill her. I hate them. I hate THEM. I DESPISE them.

"You might be angry. But calm down, please. I'm just as angry as you are. Keep this in mind for as long as you'll live and fight. Make them pay."
She spoke up in a snappy tone as she left the room. Her demeanor was powerful and menacing. I looked down at my hands. I clutched my fists and started punching the mattress in anger. Tears gush out of my eyes as I beat the mattress more in anger.
"I swear I'll kill every one of you!"
I scream, muffled by my bandages.
"I despise you."
