" I am going to rot in here." 

Kokushibou gave you a tiny glance as he stock in another book into the fantasy-labeled shelf. It was quiet rare for you to express what you were thinking since you were usually so quiet. Perhaps because you've known him for a few months and hung out with him more often than other workers in the bookstore, that you became more opened up to him.

" Why did I even chose this work?" You continued, handing him another book to be put in.

" Then why did you?" He questioned, finished with the section and pushed the cart to the children section.

Trailing behind him while pushing another cart, you said, " Money, Kokushibou. It's also hard to find a part-time job, you know? I am also trying to keep up with college's work."

He didn't replied and that was the end of your conversation as you both continued to stock the books in the section. Boredom grew and grew inside you as time passed by. This work seemed dull to you, but at least you were paid. Once you have enough money and finished college, you quit immediately.

You glanced at Kokushibou. If it wasn't for him, you'd have quit long ago. He was quiet, perhaps even more than you being quiet, but skillful and fast in managing things. Your friendship with him started with him helping you adjusting to the work by the manager's order, only for a friendship to bloom between both of you. Being observant, not only you noticed how good he is in working, but also his attractiveness.

Kokushibou has a long, spiky black hair tied in a ponytail; dark eyes and pale skin. His name ' Kokushibou ' was a name when he was on a work shift. When he finished, he was called Mitchikatsu. You found out about this from his twin brother, Yoriichi, that often visiting the store to give a lunch box to his brother.

If you could rate his attractiveness, you'd give a 9/10. His sombre expression gave off an intimidating and scary vibes that sometimes scared away the customers. Probably the reason he wasn't in charge of the counter.

" Just how bored are you that you keep staring at me?"

You jumped, caught by the man. Looking away and trying to hide the little redness on your cheeks, you said nothing. Kokushibou stared at you for a few seconds before sighing.

" Let's...play a game."

" Huh?" You turned to him, eyes widened.

This man, who looked like he doesn't know the definition of fun, was inviting you to play a game?

Kokushibou put up a finger, " In an hour, both of our shift will be done and we are also in charge of closing the store for today. By one-hour, let's stock these books in the sections quickly. The one who finished first gets to be treated a meal by the one who loses."

How... interesting.

Despite taken back by how a bit weird he was acting, his offer was tempting. Instead of spending one-hour restocking the books in boring atmosphere, why not turned it into something more challenging and exciting?

You hummed, " A meal from a restaurant?"

" Includes a dessert."

" Deal."

And with that, both of you started the challenge just as quick as it started.

|||||

You've almost done, only one more book to be put in the adult section. But it seemed that Kokushibou was also heading to the same section. Unfortunately, he was more quicker than you in speed, as he easily ran passed you to the section.

Not wanting to lose, you reached out one hand and grabbed his apron holding him back.

The man looked over his shoulders, " That's cheating, (Y/N)."

" There's no condition set anyway!" You pulled the stings off so the apron would fall off to distract him.

While it certainly did, as Kokushibou stepped on the apron and slipping to the ground, he managed to grab your ankle to let you meet the same fate as his. Loud thump sound echoed in the store when both workers fell onto the floor. Kokushibou was the first to get up, already sprinting past you, but then noticed that you didn't move.

" (Y/N)?" He stopped. " (Y/N)." He called again but there was no response.

Panic starting to fill inside him as he dropped his book and went back to you, forcing himself to calm down and maintain the situation --

In the form action of sike, you grabbed his apron on the floor nearby and threw it to his face before going on your feet and dashed towards the section.

"(Y/N)!"

Oh, you knew you were so in trouble at the tone of his voice, but that still didn't stopped you from putting in the book in the shelf to claim your victory. Once you done, you turned around and faced your co-worker who had a visible irritation on his face.

" Are you mad that I used dirty tricks?" You gulped, taking a step back at how intimidating he was.

Kokushibou didn't answer. He grabbed your shoulders, forcing you to stay put as he used another hand to lift your chin and moved your head sideways. It then clicked inside you that he was checking for any injuries.

" I am okay," you said, blushing at how close and touchy he was, " I was just pretending. You know me, I like taking risks."

" Don't do that again." He warned.

" Don't tell me what to do."

"...." Sighing, he let you go and looked away. " I was...worried for a second back there."

Realizing that you really did scaring this man into thinking that you were injured, you immediately felt guilty.

" Look -- I am sorry, Kokushibou. I won't do anything that hurt myself."

He looked at you. " You can't promise that."

" But I can try."

There was a moment of silence as you both stared at each other. Kokushibou put a hand over his face and you were taken back once again at the sight of his shoulders moving as he let out a short chuckle.

" Well," a small smile was on his face, " you won, anyway. Congratulations. So, does 8 p.m. tonight good for me to take you to your meal reward?"

You smiled back, " Yeah. That's good."

As you both did final clean up in the store, something occured to you as you took off your apron.

"...Hey, Kokushibou..." You slowly began, "...correct me if I am wrong...but...the game and the meal as a reward...were you trying to ask me out or something?"

And without even turning around as he locked the back door, Kokushibo replied, " Will you reject me if I say yes?"

" No."

" Then, yes."

A/N : I hope I got the reader's ISTP personality right. Please tell me if I did any mistake with it. Also, sorry if Kokushibou is a bit ooc.

Tsugikuni brothers being flirted by their women.

Extra point : Fumiko doesn't really know how to flirt actually but Douma had given her a few lesson here and there ( Muzan is not pleased when he found out about this )

Uta used a dirty pick-up line once and Yoriichi was literally on the floor, becoming a blushing mess.

Kokushibou : You have potential.

Akaza : You could be stronger if you just...eat more.

Douma : I know you want to. Humans are bound to be curious.

Tamaki Amajiki : * Starts to cry* Who are you people

Muzan : Join us, child, become stronger.

But for real, imagine what Tamaki could do if he...eats people.

Kny ramble, (I should start numbering these lol)

Remember how Kokushibou said that whenever he and Yoriichi talked about how their breathing styles have no successors, and Yoriichi suddenly becomes optimistic and smiles? I shared the same confusion with Kokushibou, on why Yoriichi seems quite delighted at such idea.

Then it struck me that probably means, having no need to teach breathing styles means no more demons. The Breathing style started as a way to enhance the body for Yoriichi, a way to utilise the body to become better in terms of movement and maybe health...before being seeing as a weapon. It's being weaponized. For greater good, granted, but still. And Yoriichi hates conflict.

Having no successors can be meant that breathing style is no longer needed because demons are gone. But there's a possibility it can be used for another intention, and Yoriichi, who has seen how greed and envy influenced his brother, guesses that breathing style could take a very, very bad turn.

A way to get the body stronger? Faster? For what purpose? Violence then, if not for demons slaying.

Yoriichi is probably grateful that the demon slayer organisation is a hidden one, a small community that has only a small splotch of corruption between the slayers from the difference in morals, and that not everyone believes in demons.

Breathing style can be used for a good cause...as it also can be weaponized for destruction.
