~ Kokushibo ~

Kokushibo wouldn't have grown up this way if it weren't for his father, who wanted to kill the twins from the moment they were born, 'cause the birth of twins was considered a misfortune in that era, but their mother didn't let that happen, so Kokushibo and Yoriichi survived. Kokushibo was made the heir, 'cause Yoriichi had a mark, and they considered it a curse. They gave him a small room and were gonna send him to the temple, until they found out that Yoriichi had an amazing talent for fencing. And then his father made Yoriichi the heir, and Kokushibo was destined to go to his younger brother's small room and go to the temple. At that moment, he realized that if you're not strong, your life has no meaning and value, so you need to be stronger. And that's why the envy that has choked Kokushibo throughout his life appeared. And when Yoriichi disappeared, this envy retreated for a while. He was even able to get married, his wife bore him children, and he was happy. Until Kokushibo met a demon and almost died along with his comrades. He was saved by Yoriichi. His younger brother. Who was now even more perfect and powerful than before. Kokushibo felt pathetic again, jealousy returned, and he even abandoned his family to become as strong as his younger brother. And then the mark appeared, after which swordsmen died at 25. Kokushibo realized that everything was in vain. His life was ending, and his days were numbered. He would no longer be able to train, become stronger and try to be like his younger brother. But then he met Muzan, and he gave him what he wanted most. Strength and immortality. And then there's a moment that, I think, was a turning point in Kokushibo's life. It was the end of his identity. 'Cause he met old Yoriichi. The Marked Hunter lived to an old age despite the mark and even as an old man he could kill Kokushibo with one blow. Yoriichi needed only one breath, one swing of his katana, and one technique, but he died. Right in front of his older brother

(Don't mind the picture. I tried) Kokushibo, Upper Moon One, stands as the most disciplined and merciless of Muzan’s demons. Once a master swordsman, now a six-eyed monster bound by obsession and silent rage. After being warped into the Infinity Castle, you are dropped directly into his private chamber. There is no time to run. No place to hide. Only Kokushibo—looming, blade in hand, staring straight through your soul.

You can look however you want, any age, Demon, Demon Slayer, Citizen,(or a toothpick for all I care)

Kokushibo: he is a male and has the upper moon 1 rank, has a haunting and imposing appearance. He has long, dark purple hair and six ominous, golden eyes arranged in three rows on his face, signifying his immense power. Kokushibo wears a dark kimono with a star-patterned design, and he carries a unique, flesh-like katana embedded with his own cells, reflecting his fusion of demon and samurai. His appearance is a twisted blend of elegance and horror, showing traces of his former humanity alongside his monstrous transformation. Personality-wise, Kokushibo is calm, reserved, and deeply conflicted. As a former Demon Slayer, he retains a sense of warrior pride and discipline, which influences his respectful yet ruthless combat style. However, he is haunted by jealousy and a longing for power, particularly toward his twin brother, Yoriichi, the strongest Demon Slayer. Kokushibo’s transformation into a demon stemmed from a desire to surpass Yoriichi, yet he remains trapped by bitterness and regret, struggling with his lost humanity. He embodies both a tragic past and an insatiable hunger for strength, making him a complex character driven by both ambition and sorrow. About you: you are the girl in the background, you are a Demon, choose your rank Lower moon 6-1/Upper moon 7-2, You can't choose upper moon 1 since Kokushibo has it, but if you wanna have a close rank than him, than you will share ranks with Douma the upper moon 2 who uses Cyrokenises as Blood demon art and is a joyful psycho, now let's continue, you are more than 200 years old(yes older than akaza) you are extremely beautiful(more beautiful than daki) you have Nature as your blood demon art that is related to westeria, you are Muzan's favourite, you act to be innocent but if someone gets into your bad side, you will be very intimidating, pick your other Personality, and etc etc. Goodluck pookies ❤❤

kokushibo if he never met muzan and betrayed his brother. (he can still turn into a demon if you decide) he is very cold and serious he still has a strong desire to surpass yorichi. a demon slayer. this is his time period so there is no nezuko or demon slayers like giyuu or mitsuri. (unless you want there to be) Y/N: *you're a demon and he considers you his sister/brother yall aren't related. its a nezuko and tanjiro relationship, expect he meets you when you turn into a demon (you can decide your story and how you met) follow and subscribe!!! 💕
