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

Chapter 1.

You might be wondering who I am. Well, to be fair I've never known either. But for as long as I can remember I've been Chō. Silly little Chō Hikari and her unfortunate upbringing. Everything started when my mother decided to have a descendant that will inherit her Breathing Technique, and that was me. I was birthed in secret in our isolated mansion near the village, at the entrance of a deep forest. No one knew about me or my identity, I was a secret to society shielded by my family. Before me, my mother had my sister, Tsumiki. She's been my best friend ever since I can remember, my only best friend. It feels pathetic, it does, but that's just how I've grown up.

My mother trained me and taught me her Breathing Technique ever since I was 6. It felt like I was just a fighting tool, not everything was peaceful in this household. I've been taught and disciplined to stay in my own liane and not act up and make decisions on the spot. My father taught me how to read and write, he taught me some tongue twisters as well. My sister made sure I wasn't alone all the time and listened to me whenever I was upset. She was like the sun. As I said, not everything was perfect. My mother told me a story from long ago. She was a Hashira in training at a corporation called the Demon Slayer Corp. She let me know that she fought in a bloody battle alongside her partners and ended up injuring herself to the point where half of her right lung had to be surgically removed and her left knee was weak and frail. She was really weak, this battle seemed to have drained all her energy, and after all of this, she wasn't allowed to be a Hashira anymore. If she had injured herself again she would've been dead. She blames the corporation for all of this. I was taken aback of course, until she started to tell me even more about this whole evil corporation that ruined her life. As anyone would, I started hating this group of people. They were brutal towards every demon that stood in their path. I and my mother promised to never attack innocent demons. The ones that never attacked first and seemed pacifist. She'd tell me nightmarish stories about how these people would brutally murder these demons without giving them a chance. Me and my sister were terrified. And so I was lead to believe that the Demon Slayer Corp. was a horrible place where only murderers went and got recruited. So I never went to Final Selection.

The thing about the females in this bloodline is that our blood would have different properties. The DNA and white blood cells in the blood are mutated to the point where it becomes like a chemical that can either explode or heal wounds. It really is magical. A common property about the blood in the family is that it can vaporize demons, if it is poured on their neck in a huge amount. So you'd have to store a few drops of blood in a sterilized bottle for a few months until you have a weapon against the demons that rule the earth at night. Me and my mother only used it when it was needed. My blood can be used to heal. A small drop of blood can heal a scratch or open wound. It coagulates the open wound and heals it over time. Of course, I can't just let myself bleed out for a bigger and more serious wound, so my mother brought in herbs and special chemical substances to help me create healing serums and creams. These came in very handy in my daily life of training aimlessly.

All these years I've been alone until one day, a small energetic boy with flaming hair came up from the forest our house was located in and curiously stared at me with his big red eyes. I was taken aback, of course, I've never let anyone interact with me, and I have never interacted with a person my age either. He walked up to the gate and peeked over to see me training. He spoke up, smiling respectfully.
"Hi! I'm Kyojuro. I can see that you're training!"
"Y-Yea! I'm Chō. Pleased to meet you."
I awkwardly stare at him and tilt my head in curiosity. He looked weak, but he looked really out of place. He was really bright.
"Does that mean you're training to become a Demon Slayer?" He perked up and made a silly face.
"Demon Slayer...No."
I bluntly say as I smack the dummy violently. Just hearing the word Demon Slayer makes me angry.
"Why not?"
"My mother is injured and bedridden because of these people."
"My mother is also sick! But those people didn't do her any harm."
"Sorry to hear. But my situation is different!"
I protest as I drop the wooden sword. I walk towards the gate and stare at the boy.
"You have pretty hair!"
He says as he reaches out to touch it. I back away and feel my cheek warming up. If he wants to become a Demon Slayer, he would act in a meaner demeanor. He's strange.
"I have to go now. Can we see each other again tomorrow?"

His smile widens and he giggles happily. I nod my head. Maybe not all Demon Slayers are bound to be like this. The boy pokes me and leaves out of the forest towards the village. He surely seemed like a very nice young boy. But he wanted to become a Demon Slayer. I didn't trust him but he did compliment my hair.

My mother called out for me and I ran inside, kneeling down in front of her bed. She got up weakly and smiled.
"Have you finished your training?"
"Yes, mother."
She smiled and pulled my head on her chest as she caressed my hair.
"No matter what, defend yourself. Defend yourself from those monsters. Do it for your mother, okay?"
"Yes."
I hesitantly answer.
"Good. That's a good girl."
