In Demon Slayer With Heavenly Insight

Chapter 1: Kimetsu no yaiba

Demons Slayer World, Nada Spider Mountain.

A place in the wilderness.

The quiet moonlight spread on the ground, the full moon hung high, illuminating the doubts of a certain young man in the forest.

Breathing techniques?,Hashiras??,Demon Slayer Corps???

"Have I transmigrated to Kimetsu no yaiba?"

At this moment, Ren Katsuragi's eyes were full of confusion.

The thick smell of blood in the air, the cold wind all around, the corpses of the Demon Slayers everywhere, and the cries one after another not far away.These all remind him of the fact that he has traveled through time.

Then, there was a crisp sound in his head.

[Ding! It has been detected that you have transmigrated to the world of Demon Slayer: Kimetsu no Yaiba. In order to support your survival rate in this cruel world, we hereby reward you Tenchi Seiki! ]

[ Tenchi Seiki- Heavens Insight/Heavenly Understanding]

[Good Luck on your new journey!!!]

In an instant, Ren's mind became cool.Everything in front of him suddenly became clearly visible, and his brain began to work at high speed.His senses became so sharp that he can even see some trivial details from the surrounding environment.

Combining the prompts , memories and the surrounding situation just now, Ren had already deduced where he was currently.

Natian Spider Mountain!

"This is not good!"

Ren's heart became tense instantly."My Heavenly Insight certainly shows my future growth and i needs consider time for it but I don't have any skills or equipment currently to escape from here !"

"If a random demon comes here now , I'm afraid I'll have to die again here!"

Walking quietly.Ren prayed silently in his heart.

"I am waste, a waste is insignificant to others."

Ren tried to move more,But just as he turned around,

"hey hey hey", sound came from the shadows behind him.

Ren's eyes widened: "I can't be so unlucky, right?"

Something squirmed in the shadows.

Even though Ren didn't want to believe it at all, the ferocious face that gradually emerged made his heart drop to the bottom.

Yes, Ren met his first Demon..but he is still a normal person.

The Demon had a strong body and a ferocious face. It stared at Ren closely, as if it was looking at a delicious food.saliva flowed out of his big mouth: "Hungry... uh... you smell so good!"

This scene was extremely weird, but Ren saw something entirely different from others.

[You observe the Demons teeth, your eyes light up, and you understand how to make a crooked smile]

[Your heart beats faster and faster,you are a little nervous. You have learned the high-frequency heart beating technique, your body temperature rises, and your Demon Slayer Mark are about to awaken.]

Huh???

[You feel the other person's enthusiasm, and you feel something in your heart, and create a breathing method that can heat your body, the hot breathing method! ]

"Fuck!" Ren was stunned.

The inspiration in my mind just poured out subconsciously, and I accidentally thought it so much.

And i actually created a unique breathing technique? ! Although it is not useful but how many people are there who created their own breathing techniques

Is this the power of Tenchi Seiki?

Ren felt happy.But the next he felt dizziness.

It seems that my brain is currently unable to think deeply for a long time. How long has it passed?It was as if I had been overcharged, my blood sugar had dropped a lot.

And just when Ren was thinking about it, the evil ghost could no longer restrain the desire in his heart.

His mouth aimed at Ren's neck, and he rushed over with joy!Seeing this, Ren subconsciously twisted his neck and easily dodged the evil demon's attack.

With the excessive rise in body temperature, Ren unexpectedly discovered that not only did his body not fall into weakness,On the contrary, he feel more powerful than usual!

At this time, from the treetops above Ren's head, a figure jumped down as lightly as a butterfly.

She wore a delicate patterned Nichirin sword on her waist, and the colorful feathers of butterfly wings hang casually behind her.

Purple hair tips, long black hair, neatly tied up with delicate butterfly hairpins.She has a graceful figure and looks like a fairy descended from the sky.

The person who came was none other than one of the Nine Hashiras of the Demon Slayer Squad.

Insect Hashira- kocho shinobu

kocho shinobu is a hashira-level warrior whose agility is one of the best among the hashiras. In just one breath, she was already standing in front of Ren.

She Drew her sword and swing it, the speed of the neat sword swing was dazzling! And Ren saw all of it very clearly.

[You observed Insect Hashira's elegant sword skills and were greatly shocked. Your inner thoughts become clear and you successfully mastered sword skills]

"Insect's Breathing-Dance of the butterfly:Caprice(Mushi no kokyo -Chō no mai: Tawamure)"

T/N

[Insect breathing:Dance of the Butterfly: Caprice

The user leaps into the air and charges towards the opponent, stinging them multiple times with their blade to inject poison in just seemingly one strike]

Shinobu flew in the air like a butterfly, using its poisonous blade to quickly stab the Demon next to Ren.The venom was injected into the demon's body, and the demon that was still full of vitality suddenly withered.

After defeating the opponent,She came to Ren's side.

The colorful feathers of butterfly wings float slowly like wings, wafting a sweet fragrance.Shinobu narrowed her eyes and showed a sweet smile.

"Moshi moshi , are you okay ?"

"It's okay,I'm alright." Ren replied.

He just learnt and mastered sword techniques and now his mind became tired and he can't help but want to take a nap.At this time, ren was dazed, and his vision gradually became blurred due to excessive use of his brain.

At this moment, the Shinobus face came directly towards him!A spring-like smile bloomed on her face, and her purple colored eyes stared straight at him.

The distance was so close that Ren could even smell the sweet scent of wisteria coming from the other party.Shinobu blinked her eyes, and her purple eyes gradually looked towards Ren.

Her Eyes move downward.Until she saw a black pattern on rens neck.

"Mark?!"

Shinobu's purple pupils dilated instantly, and the smile on her shocked face disappeared for a moment.As a reasearcher She happened to see records of Demon slayer marks while studying pharmacology, but she didn't remember them very clearly.

She only knows that after awakening these so-called marks the body's functions will be greatly improved, at least to several times the usual fighting ability.But the young man in front of her was not wearing Demon Slayer costumes, he was obviously an ordinary person.

But he awakened the mark What does this mean?

This person has the qualifications to become a Hashira!

She didn't dare to make a rash decision, so she planned to return back to lord to inform.

And The next moment, the Butterfly Ninja returned to her usual smile.

"Ah, ah, this lovely gentleman, what is your name?"

"Ren,Katsuragi Ren."

"Okay Ren- san, where are you going to go next? Are you going home?"

Ren paused: "I have no family, I am an orphan."

Shinobu looked little sad: "Really? That's such a pity. Most of our members of the Demon Slayer Squad are orphans. Why don't you, sir, come with me?"

Ren lowered his head and thought.

My own heaven-defying understanding needs to be developed and utilized in combination with breathing techniques or demon blood art techniques, but I am still very weak and need time to develop.

There are too many uncertainties in the demon side ,Muzan may have the idea of even dissecting me .

But it's different here with the Demon Slayers.

Not only do you have the opportunity to observe the breathing techniques of each Hashiras but you can also become a powerful swordsman that can kill demons. Wouldn't it be nice?

So Ren chose to join the Demon Slayer Squad.

Shinobu smile happily after learning Ren's answer.

"Then Ren -San, please go back to the Butterfly mansion with me first.So that I can take a look at your body. You must be exhausted from fighting the demon just now."

Ren nodded, but as soon as he stood up, his brain felt dizzy.

The long period heavenly insight overloaded ren brain, and he stumbled and fell into the arms of shinobu

You-Know

Insect Breathing is a Breathing Style that mimics insects, specifically their lethal stings and movements, and replicates it with user's movements, techniques and abilities. Most, if not all, known techniques and forms include stabbing, thrusting, and making shallow cuts with a specially coated/made sword to inflict multiple wounds onto the intended target in order to inject various lethal wisteria-based poisons into them. Users of Insect Breathing also visualize themselves seemingly manifesting insects (mainly butterflies) when unleashing its techniques.

This Breathing Style is the personal creation of Shinobu Kocho, who designed it to compensate for her lack of physical strength to behead a demon.Hence, this sword style can only be utilized by her and only using a unique katana with a needle-like tip, resembling an insect's stinger in appearance and function. The "stinger" is designed for injection of Wisteria poison into demons. As noted by Doma, the blade sheath was also designed as a portable poison mixer, allowing Shinobu to change the poison that coats her blade at a moment's notice.
