Chapter 8: Demon Slayer Blade, Part 3

Two weeks had passed since I arrived at the Butterfly Mansion. During that time, I focused on recovering from the injuries inflicted by Muzan and regaining my previous physical condition through rehabilitation training.

‘About 90%…’

I assessed my body and determined that I had almost fully recovered.

As I was doing so, someone opened the door.

“Good morning, Demonic God.”

It was Kanzaki Aoi.

Having spent two weeks together, her initial coldness had vanished.

A faint smile graced her lips, indicating a degree of familiarity between us.

“Good morning, Aoi. Did you sleep well?”

“Yes, I slept well.”

Her tone remained formal, but I knew it was her usual demeanor.

There was no need to be intimidated or offended.

“Will you have your meal now?”

“Hmm, I’ll eat a little later. I need to train.”

“Then please let me know when you’re finished training.

I’ll prepare your meal.”

I smiled. “Thank you, as always.”

“It’s my duty.”

My words seemed to have embarrassed her, as her expression turned cold.

“Even if it’s your duty, I still appreciate it.”

Aoi seemed flustered by my unexpected response.

“Th-Then, please train diligently, Demonic God.”

With that, she left.

I was right. Aoi didn’t usually stutter.

‘Time to train.’

With Aoi gone, I prepared for my training, aiming to assess my current condition.

I left the Butterfly Mansion and entered a nearby mountain.

I had come here to resume my training in the Demonic Sword Technique.

Having only recently acquired it, using the technique while injured risked further harm.

Thus, I refrained from using it for two weeks.

Two weeks might not seem long, but it felt like an eternity to me.

Especially since I trained daily.

Regardless, I was grateful to finally resume practicing the Demonic Sword Technique, and I assumed my stance.

‘Haa…’

I inhaled deeply, and as I exhaled, I moved.

[Demonic Sword Technique Demonic One-Sword Strike]

I unleashed the first form of the Demonic Sword Technique.

It cleanly sliced through the trees before me.

Without pause, I continued with the next form.

[Demonic Sword Technique Demonic Formation]

While lacking the sharpness of Demonic One-Sword Strike, Demonic Formation possessed overwhelming speed.

I moved too fast for the eye to follow, cutting down the trees before me.

Then, I executed the final form.

[Demonic Sword Technique Demonic Heaven Splitter]

As the final form, Demonic Heaven Splitter possessed the greatest power.

Mastering it would grant the ability to cleave even the heavens.

‘I’m still not used to it.’

It was only natural. I had only acquired the technique two weeks ago.

However, the good news was that its level had increased significantly.

Thanks to the battle with Kibutsuji Muzan.

[Demonic Sword Technique Lv.4
Competent in using the Demonic Sword Technique.]

My general Swordsmanship skill had been absorbed into the Demonic Sword Technique.

A natural progression. While Swordsmanship granted access to all sword techniques, the Demonic Sword Technique was the most powerful of them all.

While I could still use other sword techniques, I had no intention of learning them.

The Demonic Sword Technique was already the pinnacle.

Furthermore, its mastery was challenging, demanding my full attention.

I would continue using it unless I achieved mastery or encountered a situation requiring a different technique.

Another week passed, marking three weeks since my arrival in the Demon Slayer world.

My body had fully recovered.

The wounds from Kibutsuji Muzan had vanished without a trace.

I was currently at the Ubuyashiki Manor, along with the other Hashira.

“You encountered Kibutsuji Muzan! What incredible luck! The Demon Slayer Corps’ ultimate goal is to kill Kibutsuji Muzan! How was he?”

Rengoku Kyojuro, the Flame Hashira.

“I’ll be the one to take Kibutsuji Muzan’s head.

I’ll put on a dazzling display of blood and gore. It’ll be flamboyant!”

Uzui Tengen, the Sound Hashira.

‘I wonder what Kibutsuji Muzan was like. I want to ask, but I’m too embarrassed to speak in front of everyone…!’

Kanroji Mitsuri, the Love Hashira.

“Ah… The time has finally come. The time to kill Kibutsuji Muzan… the pitiful creature!”

Himejima Gyomai, the Stone Hashira.

‘What was that cloud shape called again…’

Tokito Muichiro, the Mist Hashira.

“I’m furious that I wasn’t the one to encounter Kibutsuji Muzan.”

Iguro Obanai, the Serpent Hashira.

‘Why am I even here?’

Tomioka Giyu, the Water Hashira.

“It’s been a while since we’ve all gathered like this~”

Kocho Shinobu, the Insect Hashira.

“I will kill Kibutsuji Muzan!”

Shinazugawa Sanemi, the Wind Hashira.

And then, Ubuyashiki Kagaya, the leader of the Demon Slayer Corps, appeared.

“Let the Hashira meeting commence.”
