For hundreds of years Humanity came to know the existence of creatures that shouldn't have walked the earth.

Powerful, undying demons who'd salvage town after town for their limitless appetite for Human body, flesh and blood...

Although humanity have created an organization that protects and defeats demons at night.

How can humans defeat demons in the first place, how can humans defeat creatures that heals and never ages.

For generations, our town who remained hidden and away from those protectors did what we could and what we MUST.

"Tanjirou-san we are all ready for you~" one of the kids yelled from downstairs.

"I am coming down" I replied.

My long black hair with burgundy tips tucked properly, hidden beneath the tsunokakushi which is the traditional white headdress worn by brides.

That's right.

Today is my wedding day, I got up from my seat and retrieved the last piece of my white shiromuku (wedding kimono) slowly putting it on.

I took a deep breath and opened the door, taking my steps one at a time bidding farewell to the place that I can never return back to.

"Hurry up, he won't be happy if you're walking slow!" one of the escort shouted.

"Hey! It's okay" Another escort whispered assisting me to get in the carriage.

The night is dark, hiding his face but not his hair... Those black hairs with fading blue at the tips.

"Thank you-" I softly whispered.

"We have arrived, get out now!"

As soon as I got off the carriage, my eyes caught a glimpse of the huge mansion in front of me.

The carriage and everyone disappeared except me and one other person.

"Shall we go in?" he whispered holding out his hand pointing to the mansion.

He's that guy earlier...

We were able to get in the mansion, he must be working here.

He led me all the way to my bedroom and even asked me if I want to have some food but I declined.

"The master will be a little late tonight... so please make yourself at home" he said before closing the door.

I immediately ran to the door but as soon as I heard the sound of the door click my heart sank. I felt hopeless.

I guess it isn't that easy to get out of here and escape...

No, I shouldn't think of escaping... what would happen to everyone in town if I do.

- - - -

*knock knock*

"yes" I sleepily answered slowly making my way to the door making sure I don't stumble on my way.

The door opened and revealed the escort yesterday, he is now dressed in a butler's uniform, he really does work here.

"Tanjirou-sama, you might want to put something less revealing first..." he muttered looking at his left.

That's right! Why am I feeling so light and cold as soon as I realized what I was wearing I could feel all the blood rushing to my face, I quickly slammed the door.

"We will be waiting for you in the dining hall tanjirou-sama" I heard him said from outside the room, I then hear the footsteps slowly disappearing.

Think tanjirou! What in the world are you doing? I was supposed to still be in my dress...

I walked towards the huge mirror leaning against the wall just on the right side of the bed.

A white transparent night gown, this night gown isn't mine... I didn't even bring anything from home and I could've sworn I didn't change last night!

I was able to get something appropriate from the wardrobe, a simple laced dress.

I am just a few steps from the door, I can feel my heartbeat racing the longer I stare at the door knob.

I dashed to the door but when I twisted the door knob it is locked.

"Tanjirou-sama"

Oh no...

"I wasn't- it wasn't like that" my hands begin to shake still holding the doorknob.

What would happen to me, what would happen to the town knowing that I tried to run...

"This way Tanjirou-sama" he whispered as he turned around and started walking leading me to the dining hall.

"I- uh I don't really know what to call you mister" I initiated the conversation.

You see, he's just looking at me this entire time that I sat down on this table. I don't feel like eating so basically he's staring at me staring at my food.

"Inosuke" he replied with a faint smile.

"Inosuke-san, is the master not eating with me?"

I could hear him chuckle at what I just said. I mean, shouldn't he be here? I haven't even seen him or anyone but Inosuke-san.

I could feel my heart racing hearing the steps he took as he made his way to my side of the table.

He then shifted my chair to face him and leaned forward, stopping just inches away from my face.

"You see tanjirou-sama..." I can smell his hair and that particular sweet scent coming from him.

Now that I take a closer look at him, his eyes are soft pale green. He slowly leaned closer and whispered just by my ear.

"You are his food... Tanjirou-sama" I froze and started trembling, no keep calm just be calm tanjirou.

You mustn't let him know you are scared.

"You are quite amusing tanjirou-sama..." he started mumbling as he walked away from me.

"All the girls... started running every single time I said it."

I know, I know from the very beginning why I am being brought here, so don't fret tanjirou.

You knew all this time and you are ready for it. I keep reassuring myself.

"shall we go for a little adventure tanjirou-sama?" bluntly asking me with a smile.

I nodded and we started walking to the hallways, the mansion is still lit with lights because of the huge blackout curtains covering the windows.

Of course, the master of the house Is a demon after all.

We spent the day roaming the mansion, room after room he introduced what it was for and particularly when the master uses the room and of course Inosuke-san makes sure that I have food and tea.

The sun has finally set and there's still one more place that we haven't been to... the garden.

Inosuke-san stopped on his tracks and looked at his watch.

"I think that will be all tanjirou-sama, we will do it some other time" he whispered leading me back inside my room. I heard him locking me in again.

My feet hurts from all that walking and I can barely breathe on this dress.

As soon as I got out of the shower I picked one of the dresses in the wardrobe again.

I picked one of the dresses instead of putting on another transparent night gown before tucking myself in bed.

The mansion sure is silent... Come to think of it. I haven't really seen anyone but Inosuke-san.

And then there's that master too, I haven't seen the demon... the demon I am wed to.

I suddenly woke up feeling the cold wind in the room, I lifted my head and saw the flowing curtains.

As soon as I arrived by the window, two hands grabbed me from behind embracing me tightly.

"Close your eyes" he commanded. To my surprise I did what he told me, I don't know why but his commanding voice...

This must be him.

In a split second my back is already against the wall... I could feel both of his hands gripping my dress tight before tearing it apart. I have nothing beneath this dress...

My eyes opened and at that exact moment my knees weaken as his lips invaded mine, roughly pushing his tongue inside and when he did

His tongue roamed inside my mouth, his hands slowly sliding the dress off of me.

But then he suddenly disappeared, my knees finally gave up and my whole body crashed to the floor.

I started looking around but the curtains on the window is too thick for the moon light to pass through. I can barely see anything, except for the white sheets of the bed.

I slowly stood up, using the torn dress to cover my front at least.

"Tell me..." that voice, he's still in this room!

"Aren't you afraid of me?" he whispered.

I slowly made my way towards the bed, where the voice is coming from.

I am... I am a human after all but I mustn't be afraid, I can't be afraid.

"No-"

"You sure sound NOT afraid" he replied chuckling emphasizing on the word.

I know what I must do... I've been told and trained what I must do. And that is to make this demon happy. For my family and for my town...

I let go of my dress and slowly climbed and sat on the bed listening and observing what will happen next.

I have to do it... I have to

- - - -

"Do you really want to" the demon whispered cornering tanjirou in bed with both of his arms on the sides of her face.

"Yes" as she puts her hand on his nape pulling the demon down. She opened her mouth voluntarily, the sweet and warm sensation was all the girl could feel at that exact moment.

For Tanjirou didn't know if she was doing it right, it was her first kiss you see.

The demon then grabbed tanjirou by her cheeks, as he slid his tongue inside her. He slowly lifted tanjirou without breaking the kiss and sat her on his lap.

Feeling the trembling hands of the girl, the demon broke the kiss and started licking his way down to her neck, softly sucking her skin.

The feeling building up inside tanjirou is slowly getting out of her control, gasping for air and trying to hold back her moans but she could only do so much...

His tongue then moved to her neck slowly making his way to her chest.

He playfully teased her nipples before devouring it completely with his mouth as his other hand busily massages the other.

"mmmmmh~" Tanjirou moaned grabbing the demon's hair in pleasure.

"Open wide" the demon commanded tanjirou kneeling on the bed.

Tanjirou then opened her mouth, the demon gripped tanjirou's hair and pushed his manhood inside her mouth.

"Very good" the demon whispered.

The sound of her choking and gargling her overflowing saliva continued as he pushed her head at the same time thrusting it in and out of tanjirou's mouth.

He pulled it out of her mouth, slightly pushed her on the bed and captured her lips, roughly kissing her.

"You are very good indeed Tanjirou..." he whispered before disappearing.

Tanjirou frozen, dumbfounded at what just happened. She slowly pulled the blankets and covered her body.

She could feel her cheeks getting warmer as she softly touch her lips.

*knock knock*

"Tanjirou-sama" the butler calling her woke her up.

"Just a minute!" she shouted as she hurriedly picked and changed into one of the dresses.

"You are eating well today tanjirou-sama" Inosuke muttered calling the attention of tanjirou who is still busy eating.

He sat down on the chair beside tanjirou and looked at him closely. His hand then held tanjirou's cheeks forcing her to look at him.

"Did you do it?" he excitedly asked grinning from ear to ear.

Tanjirou's face turned red seeing how intently Inosuke is looking at her. She slapped his hand and continued eating trying to hide her red face from Inosuke.

"Tanjirou-sama... did you like it?" Inosuke whispered in a chilling voice this time right by her ear.

He then cleared the hair covering her neck and started licking her exposed collar bone.

Tanjirou remained frozen in her seat, his tongue made his way to her neck. He slammed his hands on the table clearing everything on it.

Inosuke lifted tanjirou, laying her to the table before climbing up himself locking her with his arms and knees.

Instead of protesting tanjirou lifted her hands and puts them on his nape, before pulling him down capturing Inosuke's lips.

"I guess that's enough playing then?" he whispered finally breaking off the kiss.

Realizing what she has done, she covered her face with her hands in an attempt to hid her blushing face.

The place was then enveloped with inisuke's laughter.

"You are finally mine and this time you won't be getting away from me" he whispered before planting a soft kiss on her forehead.

"I remember now" Tanjirou whispered before Inosuke could capture her lips once again.

- - - -

12 years ago little tanjirou aged 6 got separated from the kids she was playing with, the very place that she got into was the mansion deep in the mountain.

Without knowing it is the mansion where the Mountain Demon resides...

"Mister! Mister!" she shouted seeing Inosuke sitting by the couch in the living room.

"Are you lost Kid?" he asked her.

"I don't live here! Of course I am lost!" she replied shouting keeping her distance from the strange man.

"Aren't you too young to be in the mountain at this hour?" he asked her.

"I know that! But father said if I show this then I will be able to get home!" she replied raising a pendant with engraved marking of the letter H.

Seeing the engraved letter the strange man started laughing.

"You're way too early to be here young girl" he whispered slowly making his way to her and crouching down to her level.

"You have beautiful eyes Mr. Stranger" she whispered with her hands cupping his face.

"Let's get you home little princess" he whispered before lifting her up as they headed down to the mountain.
