Story of Kanotsuki's backround life

Hello

Greetings, my name is Kanotsuki Aki (カオツキ 誰が), I was born in the Meiji era of Japan, to be specific I was born in 1907, I was also born with an unusual red mark that takes the shape of flames on the left (his pov) of my forehead, I grew up in the mountains with my father who will later become a demon and kill my beloved mother. I also have a brother, his name is Idukki Aki (潜入 誰が), he is three years younger than me, my family was a very peaceful bunch, we loved farming and going outside to relax in the beautiful sunlight, my father was a Demon Slayer, he was the Moon Hashira, my father was a very strong and polite person, he'd always help my mother with making our meals for us and was super courageous as well, I always looked up to my father but my younger brother never seemed to care about my father until later in our life.

 But as of one night, my father had been attacked by a demon in his sleep and has been turned into a demon, my younger brother and I weren't very strong but I kept a Butcher's knife in my hand just in case, my mother tried to fight my monstrous father but she then failed and fell to her knees then to death, my outrageous father consumed her while my younger brother and I ran as fast as we could out to the city, covered in blood. Once we made it to the city we found a lake and washed ourselves, my kimono got drenched so I had to take it off for a couple of days till we went back up to a horrible smell of blood and maggots all over the place, my younger brother stayed back since he loved our mother and didn't want to be reminded of her tragic and brutal death, Idukki was a nice kid but he was somewhat stubborn towards me, he said it was because I am loud and annoying, it hurt but I had to accept it since he would never change his mind, anyways while I was searching the house I found my mother, my mother's corpse. I looked in her hand and there it was, two Hanafuda earrings, handmade from my mother, it felt extremely disrespectful but I took the earrings and put them in the pocket of my old and torn hakama pants, I took my mothers corpse outside and dug a grave for her, after I did, Idukki and I prayed to her grave and went on to become a Demon Slayer to defeat my father once in for all.

About three years later, my brother and I have become Kinoes, when I was young I practiced being a swordsman for a while, my father assisted me but he said I reached my peak in swordsmanship, I was amazed by my own power, my power would later help in the future. I was told to have been the best swordsman in about 300 years going back to the Sengoku era, my skill reached Yoriichi Tsugikuni's level. I easily killed a Lower moon three and became the Sun and Moon Hashira at ten years old, It was quite odd for me to have two breathing styles but Moon was my main one and Idukki who has only Sun breathing taught me Sun and it became a secondary breathing of mine, it amazed Oyakata-Sama, I was super happy I impressed him but my younger brother started despising me after that, he had gotten extremely jealous and started overworking himself to be like me but then almost died from it, I advised him to stop but he never did, he stopped after multiple close-death experiences, Idukki was still a Kinoe at this point but he was way stronger now, not my level but somewhat close. He and I had a mission applied to us and it was against a Uppermoon six, their name was very familiar, I wonder who it could be.

Once Idukki and I went to the location of the Demon, there he was, my father, all big and tall with 壱 carved into his left eyeball, he was disgusting looking, I ran in and it took me some time but I eventually killed my father and beheaded him, I also grew a mark on my left chin similar to the one on my forehead but a bit smaller, my younger brother stayed back the entire time, he didn't want to kill our father out of respect but it was our job to kill demons so I followed what the Corps. said. I knew where my younger brother's heart was at this moment but my father would've killed more innocent humans if I didn't kill him, I felt horrible killing my own father but it wasn't a choice. I wish Muzan Kibutsuji could have decayed and burned away a long time ago, I would've had a peaceful life if Kibutsuji never existed.

Four years pass and I have found a young and pretty girl named Asami Rei, she had beautiful eyes of blue, like a calm tropical ocean, and luxurious blonde hair going to her shoulders, she wore a gorgeous flower kimono (yes this entire person is an avery reference shut up), her and I started dating once I was fourteen and she was thirteen in a half, she handcrafted a haori for me to go along with my Demon slayer corps. clothes, she also made a gaurd for my Nichirin katana, Asami was a very talented and hardworking person and I appreciated all her work fully.

I would, later on, become the strongest Demon Slayer to exist in our time and fulfill life with Asami and protect anyone and anything from demons. 

(forgot to add this but kano instead of putting the belt around his waist he replaced it with long white cloth and put the belt around his neck controlling his anger and rage)

(also the flower in the picture above, asami gave kano that lol)
