I'm so excited to give zaddy Kagaya his little screen time. What do you think he feels about Nao being involved with Michael Jackson? I'm guessing things won't be good.

Also, I would have to warn my readers that this story may or may not have a tragic ending. The manga readers out there would know whyyyy [>^<]

Though if I'm being honest, I'm confused whether I should follow cannon or butcher it up. I want a happy ending but I'm tempted to follow cannon.

This chapter is also a bit experimental since I wanted to try using only dialogues but well... I tried and I'm no expert. I'm not really satisfied with this chapter but I'll do better on the next one.

No beta. Enjoy☆

"What... Marriage? Onii-sama that's just....Kagaya-onii-sama, you're only fourteen years old. You're too young to marry!"

"Mimi please..."

"But why..??? You don't have to marry someone you barely know, I'll do it in your place!"

"Oh Mimi. You are too kind, but it is why I should do it as the next head of the family. "

"B-But--"

"Amane has greed to marry me and care fo me on her own free will."

"She did..? But I can take care of you, too! I'll learn how to cook meals and clean!"

"Mimi, this is my responsibility alone."

"But Onii-sama--"

"Please. Mimi, please understand."

"....."

"Mimi?"

"No."

"..?"

"No, Onii-sama.... I can't understand... why.. why you have to marry someone at such a young age just because you are the next head of the family! If you want someone to take care of you then... I'll do it! I'll gladly do it! Anything you ask, I'll do my best to fulfill it if it means that you won't be forced into this marriage! I.. I don't want you to be forced into something you don't want to do. I--"

"Mimi..."

"--just want you to be happy and--"

"..Mimi, I'm not being forced to do this."

"What? But you can't seriously be.. No. Kagaya-onii-sama.. you're really agreeing to this marriage?"

"It's for the best. And I'm doing this for you so that you won't have to marry for the sake of our family. You have so much you want to--"

"No! Onii-sama why? Why are you doing this?! I never asked this from you! "

"It's because I don't want my only sister to suffer because of our family's curse."

Ubuyashiki Kagaya is the 97th leader of the Demon Slayer Corps known mainly as "Oyakata-sama" by his subordinates and peers. He is also the current head of the Ubuyashiki Family.

Blessed with having a younger sister, Kagaya had always thought that out of all the precious things he have in his life, Nao was probably his most treasured person. She was the only innocent thing in his life that was not marred by the blood of the demon slaying.

Kagaya would always love his children above all else for their unyielding efforts and sacrifices in fighting demons but as a familial person, Kagaya's love for his younger sister would always be one of a kind.

He had always hoped that Nao deserves a normal life outside the glum life of being part of the organization.

He did not wish for her to stain her hands with the blood of others, be eternally bound to duties, and live with death by her side everyday when she could be free and could live a simple life elsewhere.

And with how Nao adored him, she would always follow him and sacrifice all that she can just to alleviate his burden.

But Kagaya did not want Nao to be locked inside this kind of life where victory was a long mile away and everywhere you went, death would follow you.

As the head of the family, he carries the burden of all the deaths of the demon slayers that were killed by demons during battle. It was his responsibility alone until the day he pass away and his heir and children would inherit his duties.

The burden of death would always be heavy coupled with the fact that having such a weak and frail body prevents Kagaya from ever lifting a sword.

He had once thought that he was undeserving of his children's love and devotion because he was a leader who couldn't lift a hand to help his comrades.

It was by far the most embarrassing and frustrating thing he has ever experienced because he wanted nothing more than to fight with his beloved children, to aid them in battle and help prevent the death of many innocent lives.

He still believes up to this day that he is undeserving so Kagaya has sworn to dedicate all of his life in managing the Demon Slayer Corps as their leader.

Similar to him, Nao has also been unfortunate to receive their family's curse. But unlike him, Nao could atleast hold a weapon, no matter how small.

She was born more strong and resilient than all the people birthed from their family line.

Yet despite this, Nao's body just like him, was still fragile and weak, and she was also cursed to live less than 30 human years.

A short life for a human but as selfish as it sounds, Kagaya would want Nao to experience those 30 years away from the endless fights between humans and demons.

Nao was simply too kind and easy to trust, she was not raised to become a leader. She was the type to be adventurous as her desire to experience the outside world was stronger than her fear of dying.

Kagaya truly wanted nothing more than to let her experience her life to the fullest but his hands were tied and he did not want to leave her so defenseless against demons.

It would have been called cruel to allow her to remain so ignorant of the ongoing battle between demons but he truly did not want to burden his only sister with that kind of responsibility.

Kagaya would carry it all on his own for the rest of his remaining human life alongside Amane and his children.

He would keep it in his family and leave Nao's hands free of any burden or responsibilities.

Then at the very least, he would be able to rest easy at the fact that Nao will never be able to feel the pain of losing so many precious people.

And she would be free from ever experiencing what it means to be ruthless for the benefit of many lives.

Kagaya has always believed that it would be for the best no matter how selfish but as he stares at the letter from Yui for what could have been the seventh time that day, Kagaya felt as if his own selfish decision was the reason why this was suddenly happening.

Then he looked at Nao's diary who was hurriedly delivered to him after Nao's disappearance was reported.

Kagaya thought.. would Nao had never disappeared if she remained by his side instead of being sent away?

Kagaya could only think of all the possibilities and what if.

I don't usually write in a diary because then I would risk peope invading my thoughts but I really can't think of any other way.

Kagaya-onii-sama sent me away in this mansion. I don't really know why but he told me that I would be safer that way.

Kagaya-onii-sama only thinks of my safety, he really cares a lot about me...

But to be honest, this situation doesn't really make me happy. I don't want to be away from Onii-sama. He's my only family left.

Amane-san is supposed to be part of the family now since she's married to Onii-sama and then the twins...

But I can't bring myself to accept them.

We were never close in the first place and I've always been jealous because Amane-san is always with Onii-sama.

I feel bad for thinking that way but she's Kagaya-onii-sama's wife now and I'm just the younger sister. Onii-sama cares for her as well and she's really taken care of him. I could tell that her actions were really sincere which just makes me jealous because I also want to be beside my brother.

I'm sorry... I'm sorry if I'm so selfish. I just feel so alone in this mansion. I don't have anyone to talk to.

Yours,

Ubuyashiki Naomi

It really is quite boring here in this place. It just feels so empty.

I wonder if I'll ever see Onii-sama again. I can only see him twice or thrice a year because of how dangerous it is..

Am I really selfish to think that not seeing my brother more than five times a year is unfair?

I feel so lonely without him..

Yours,

It really is so lonely to be alone.

I want to go home...

I wonder if Onii-sama is okay. Is he eating properly? I hope he isn't pushing himself too hard...

Is he getting enough sleep and rest? Please be well, Kagaya-onii-sama.

I really worry a lot. I hope Amane-san nags at you as often as I do so you would take care of yourself more.

Writing letters seem boring but it's the only thing connecting me with you so I can't be picky though I would have to confess that waiting for each reply has me awake most nights.

I'm too eager to receive your answers afterall because each letter from you brings me much joy.

It really does make me happy.

These letters are my only connection to you so waiting for them always feels like forever.

Yours,

Today is practically the same. I would wake up, eat, and resume etiquette lessons because I am still an Ubuyashiki.

I don't really have friends here and Yui nags at me a lot.

This place seems like a prison, everywhere I go, I would have guards following me and I can't even go outside without having a physician give me a full body checkup then I would have to waste my time getting dolled up before even stepping foot outside.

It's hard to even roam the village because of so many guards around me. I just simply gave up of going outside anymore. Not to mention that I feel queasy and faint being surrounded by so many people, it's harder to breathe than usual and the air always feels so thin even though the wind is strong.

This curse has always followed our family but right now, this is the first time I've seen it as a hindrance in my life. Because of this curse, Kagaya-onii-sama is destined to die before the age of 30.

Because of this curse, I can't go see him as often as I want to cau'z I'm stuck here..

Because of this curse, I'm always being protected and babysat by the people around me. Yuko was right...

It would have been better if I was gone.

Was there ever a meaning to my life?

I'm so lonely.. so lonely.. I want this mundane cycle to end.

Yours,

Kagaya-onii-sama.... have you ever even asked me what I really want? Just once... has it ever crossed your mind that maybe, just maybe, the only thing I want in my life is to remain by your side? Has that ever crossed your mind? Because surely... surely you know. Just how much I trust you and love you with all that I am.

You are my family, the only person who truly cares for me and the only person there is that truly understands me.. but now.. Now, I don't know anymore. I don't even know if you really knew who I was because then you wouldn't be doing this and we would still be together. But no, you sent me away and you refused to let me inside your world.

Family always helps each other, right? Kagaya-onii-sama, you, you were my family.

Now I'm starting to wonder if that was even true because unlike the future I've always wanted where I can remain by your side, I'm all alone and miles away from the one person whom I call home.

Kagaya-onii-sama, I truly do love you with all my heart. But now I'm starting to wonder whether it was only me who felt that way.

Did I ever mean anything to you?

I'm sorry, because maybe, just maybe, you sent me away because I was lacking something or I was bothering you too much. Of course, that must be it, Kagaya-onii-sama is a busy man afterall. You're simply too busy to pay me any attention. Yes.. that seems plausible. Is it alright for me to believe that? Because atleast you didn't sent me away because you hate me or you were tired of me. I'd rather believe this than bear the knowledge of your hate.

Because it is impossible, right? For Kagaya-onii-sama to hate me?

I wish you would answer me and I wish you were here so I can tell you my feelings in person instead of writing everything in ink.

Kagaya-onii-sama, if there really is a possibility, a small possibility that you hate me... then please don't ever tell me. I'd rather live the life of an ignorant fool than know that the one person who I trust most in this world have grown to despise my very existence.

I'm a coward, I would admit that but I can't bear the thought of you hating me...

If that were to happen... I.. I'd rather be a demon, then I would have a more plausible reason not to exist anymore and you would hate me for that reason because then I would be a monster... and of course I would be forced to accept that because even I hate demons.

So Kagaya-onii-sama...don't ever tell me, please don't ever tell me.

...because to live in a world where you hate me just seems meaningless.

But Kagaya-onii-sama, even if you do hate me.... know that I would never be able to hate you.... because I will continue loving you ...as my most cherished person.

Yours,

Ubuyashiki Naomi

A/N: So here's the reason why Nao got closer to Muzan.

It was loneliness alone that made her crave for companionship and he was willing to give it to her so you could understand why she was too willing to trust him since she's never really found anyone whom she could really trust other than Kagaya.

Even though Muzan is a demon, Nao hated loneliness and she felt a sense of companionship towards him that she's never felt before which is why she risked being with him despite his identity.

Because Nao loves Kagaya so much and was too dependent on his presence, being sent away from him, Kagaya took the only thing that made Nao happy and her feelings of loneliness intensified because back then, the very first friend she made which was Yuko, broke her trust.

Nao has never trusted anyone the same again, not until Muzan came.

And although she was hesitant because it was a demon who actually gave her companionship instead of an actual human being, Nao was wary but was too lonely to stop.

It's messed up but you all should take it easy on her. Loneliness makes people do crazy things, lmao.
