(REQUESTS CLOSED) Kimetsu no Yaiba Scenarios

Being a Kibutsuji/Being a Tsugikuni

REQUESTED BY: Official_Ankha

A/N: The reason this isn't titled "Muzan's Sister" is because for Muzan's path, you're Yoriichi's sister - and that quite obviously changes things (I wouldn't write incest here, that's pretty nasty).

Enjoy!

Growing up the sister of the most powerful man in Japan was an unbelievable experience.

From the moment he was born your younger brother, Muzan was a sickly thing requiring more care than your parents were sometimes able. At the tender age of five you learnt to care for your new baby brother, filling in where your parents - especially your mother - could not. You both grew up close, with him regarding you as more a mother than your own.

When the time came for you to be married off, however, he flew into a rage. You were already twenty-four, far past your prime as a young woman, and your parents felt that Muzan didn't require as much care as you had been giving him for the past twenty-odd years.

In the days before you were to be married, something strange happened.

Muzan had been getting treatments from a famed doctor, but the doctor had been recently killed - and your brother had made a full recovery. Even worse yet, it seemed he couldn't go out in the sun, something that enraged him. You had always longed to take him out in the sunlight to play once he got better, yet now he was forced to spend his days inside despite no longer on death's doorstep.

He stole you away from your fiancé in the dead of night, somehow convincing you to run away with him. Your love for your brother overrode your love for your parents and the duty to your husband-to-be's family - and you escaped with him into the mountains, where he finally revealed what he was.

Despite being horrified, you were convinced you could find a way to save him - and you spent fruitless years searching for the plant he desired. He never got angry with you, or at least not in the way you witnessed him angry with his subordinates - though he was emotionally cruel when he felt you were lacking.

Finally, after almost ten years of searching, you collapsed in an illness. Muzan was at your bedside, offering you another chance of life - and you took it, wanting nothing more than to be at your baby brother's side.

The process was painful, yet you came through and triumphed over certain death - consequently, however, you could never feel sunlight again.

It was all worth it to see your beloved little brother smile like he had when you were both human... wasn't it?

Tanjiro:

You had known nothing about this enigmatic boy, only that your brother hated him with every fiber of his being. You had witnessed enough rages from him to learn that Kamado Tanjiro was a name not to be uttered, lest you wanted a swift punishment - one of his more unfortunate subordinates was a prime example of this. (It had taken you hours to get all of the blood out of your kimono.)

Nezuko:

You smell like him. That's the first thought that crosses her mind when you both lock eyes for the first time. Instead of malice, however, she senses a deep sorrow - and you look at her with such gentle eyes that it's hard to see you as an enemy. If it came down to it, she would have few doubts about killing you - but a mutual understanding crosses between you when you see the way she protects her older brother - and she refuses to fight you if you were ever alone.

Zenitsu:

The very first time he actually saw you, he was scared to death by the man standing beside you, so much that it took him a minute to realize who he was looking at. You were so beautiful, regal, and if the king of demons wasn't standing there and staring at his group with enough malice to kill them twelve times over, he'd probably try to talk to you.
