Shizen no Kokyou. (Shinobu x Male Reader) [COMPLETED]

Chapter 46

The moment Y/N tapped into the see through world, he gasped at the sight. Upon counting, Y/N saw a total of five brains and seven hearts inside of Muzan, spread all around his body.

Y/N: I see...! That's why beheading didn't kill Muzan. Every demon has two vital organs. The heart and the brain. Beheading a demon destroys the link between these two. Cutting the ribs is rather difficult compared to cutting a neck. Thus, demon slayers stick to beheading the demons, but the real concept of how to kill a demon, is to destroy the link between the brain and heart.

He looks at Muzan, who was fighting Tanjiro, well, more like attacking Tanjiro, while the young boy tried his best to dodge and evade the seemingly lightning-speed attacks.

Y/N: According to Muzan, I haven't noticed that he has vital links all around his body, and thus, am sticking to try to behead him. So, he's not that wary of my attacks. But if I aim for the other organs, he'll instantly know and get completely on guard. I'm having trouble closing the distance between me and him even right now, if he gets on guard, I highly doubt that I'll be able to even land a scratch on him. Think. What can you do.

Shinobu: Though you have tremendous strength at your disposal, you barely seem to use it in your breathing style, any particular reason why?

Y/N's eyes widen, as he gasps and looks at his sword.

Y/N: Alright... Total Concentration... Constant!

Muzan goes to strike Tanjiro and end him once and for all, as Y/N dashes at him, followed by a trail of vines and creepers, surrounded by orange embers here and there.

Muzan suddenly notices that one of his hearts was destroyed.

Y/N gets out of his stance and looks at his hands.

Y/N: I did it...!

He looks back at Muzan, who was staring at his wound, in complete shock and... fear?

Y/N: Breathing Styles always focus on two attributes of the user. Strength, and speed. But the division is rather favoured to one, while the other is shadowed. For example, Kyou-nii's Flame Breathing focuses on strength and the force that the muscle fibres in the user's arms can exert. But Tomioka's Water Breathing on the other hand, focuses on Swift movements and flexibility of his body.

He takes a deep breath.

Y/N: Muzan is right. I'm nowhere as fast as compared to Yoriichi, but... what Yoriichi said to me earlier must be true as well. In order to kill Muzan, me and him need to work together. I think this is what he meant by that. I can move, but I'm sure I won't be able to do so for too long if I keep doing this. So I need to end this quick.

Muzan was shaking in f̶e̶a̶r̶  anger!

Muzan: That brat...! He was nowhere near his speed not too long ago. But just now... he was... he was almost... no... he was as fast as him! What... what the hell did he do?!

Y/N gets in a stance and takes a deep breath.

Y/N: Just like any breathing style, Hinokami Kagura also expects stamina and strength from the user. Though it is good enough to land a strike on Muzan, I am not fast enough with it. Yoriichi made me be able to adapt to the breathing style, yes. But... without its mastery, I can't execute the attacks to their fullest extent. But Nature Breathing on the other hand, is fast, but not strong enough to go up against Muzan. Using two breathing styles at the same time... I didn't know it was even possible... but...

He looks at Muzan.

Y/N: He's shocked. Scared, even. This means that I was able to strike without him knowing. Using the speed that comes with Nature Breathing... and the strength that comes with Hinokami Kagura... I'm confident... that I'm strong and fast enough to strike Muzan. Once I cut a link of his with this blade...

His sword was burning red.

Y/N: It takes him about 5 seconds to regenerate it, rather than normally, when he would regenerate in an instant.

He grips his sword.

Y/N: My body is begging me to stop in pain, but... I can't...! Not now, not when I know how to defeat Muzan. To kill him.

Suddenly, a crow comes in flying and cawing.

Crow: AN HOUR AND HALF UNTIL SUNRISE! CAW!

Y/N: An hour and a half, huh? Well... not like I have any choice. I personally asked my dove to relay the message to tell the Hashiras' crows to not direct any of them to Muzan in order to keep them safe. Tanjiro and Tomioka seem like they can barely even move. So it's all upon me. Kyou-nii. Mother. Father. B/N. All those who have suffered from his treacherous deeds. Please... give me the strength to kill this demon once and for all.

He suddenly chuckles.

Muzan: Find something funny?

Y/N: Oh, nothing really. It's just... you're a demon. The strongest one at that. AND, you have five frickin brains. And yet... you haven't been able to find the blue spider lily and cure yourself since centuries, have you?

He snaps his fingers, as if he remembered something.

Y/N: Hey, but wait a second...! Tamayo, the demon who cured Nezuko of her problem to be unable to walk in sunlight. She was WAYYY younger than you, wasn't she? AND, she only had one brain.

He gasps as he covers his mouth with his hand.

Y/N: No way... you couldn't possibly mean that the strongest demon, Kibitsuji Muzan, couldn't find a simple cure, and yet, a demon much younger than him was able to? Doesn't that make you look pretty dumb? Retarded, even?

Muzan was getting a bit irritated.

Y/N: Well, I suppose, it's true that five times nothing is still nothing... so...

He sticks his tongue out at Muzan.

Y/N: Ya stupid.

Muzan: *irritated* I see you really like to get on others' nerves, huh?

Y/N: Hey, speaking of seeing, I have an ability to see the emotions of others as an aura surrounding them. When I saw you, or rather you saw me, not too long ago, I saw an aura of fear around you.

He snickers.

Y/N: So... let me get this straight. Muzan, is scared of a kid? Oh wait... you mentioned Yoriichi though.

He widens his eyes and tries to hold his laughter in, but fails.

Y/N: *laughing* wait wait wait... now there's just no way that Muzan is still scared of a man who died, like what? In the Sengoku era? Wow.

Muzan was getting more and more irritated with every word coming out of Y/N's mouth.

Y/N: Hey, Muzzy boy. Where are the rest of your 1500 parts? Wait. I got another question.

He raises his finger, as if asking for permission to ask a question.

Y/N: You're not wearing any pants right now, are you? So, what do you identify as right now, anyways? Considering there's nothing... you know... THERE?

Muzan was getting so pissed at the boy's words, that he didn't even realise that it was all a strategy of Y/N to reduce the timing to sunrise.

Y/N: Hey, Muzan Jackson. You do realise that the way you talk about Nezuko makes you a pedophilic demon, right? Wait a second! White hair. Check. Ugly face. Check. Pedophile. Check. You're not a demon!

He grins.

Y/N: You're that old man on the street that gives candies to children!

Muzan yells in anger, as Y/N had hit exactly where it hurt Muzan.

His age.

Muzan: I'll fucking kill you, damn brat!

Y/N: I'd like to see you try, you old fart!

He runs at Muzan, as the demon reacts by sending a huge barrage of his whips from his back and thighs.

A/N: Chapter 46 done! Hope you guys liked it,

Till the next time,

Sayonara.
