Demon Slayer: Muzan, will you dance too?

Swordsmanship LV1 → Swordsmanship LV2

"We've already taken a small step on the road to a comeback."

System Reward: Mastery of Shadow Clone Technique

Swordsmanship LV2 → Swordsmanship LV3

"Judging solely from swordsmanship, you are no longer a beginner. Please continue your efforts and achieve your comeback soon."

System Reward: Dark Travel Technique

"As an Uchiha, you learned Tobirama's techniques, leaving Tobirama with nowhere to go."

Kiyokawa Izumi was woken up prematurely by the system's emotionless voice.

"The Mentally Handicapped System."

"I'm not a Uchiha!!"

There is no such thing as a breathing technique in the ninja world, so it might be classified as a taijutsu by the system. Whether it will be rewarded after improvement is unknown.

But swordsmanship is a feature.

The so-called comeback is just about becoming stronger, right? It's normal to receive system rewards after becoming stronger.

The system's evaluation of his swordsmanship was actually not high.

Can also understand.

After all, the ninja world is a battleground of gods.

Perhaps level five is the maximum level here, but there it would only make you a genin or chunin.

These things are not important; it's good that our strength has increased.

What left him speechless was that a whole bunch of inexplicable knowledge suddenly flooded his drowsy brain.

What use is it for him to know all this if he doesn't even have chakra?

Does he even need to use hand seals?

There's no chakra system here, so the rewards are completely useless.

Kiyokawa Izumi was also amused and slowly sat up, only to feel an unbearable headache—a huge amount of useless knowledge had suddenly appeared out of nowhere, and she didn't even have time to absorb it all, so it was no wonder she had a headache.

"Idiot System!"

He cursed under his breath again, and the slight movement made him groan. A tearing pain came from his right rib, almost making him gasp for breath.

The soreness in my arms was clearly due to overuse of my muscles, and I also felt obvious discomfort in my lungs.

This level of severity is actually nothing.

The injuries he sustained during the selection process were far more severe than what he is experiencing now. Having gone through those seven days that were nothing short of hell, he is much more resilient than he imagined.

After a brief moment of adjustment, he looked around.

No one knows who moved him into the wooden house, and they even thoughtfully covered him with a quilt.

The temperature in the mountains is indeed much higher than at the foot of the mountain, and if you don't take proper precautions to keep warm, you might get chilly.

"Are you awake?"

Urokodaki Sakonji pushed open the door and walked in, looking at Kiyokawa Izumi with some surprise—it wasn't even afternoon yet, less than half an hour had passed, and he had already woken up.

"Your eyes?"

"I'm not entirely sure, but I know my eyes turn red when I get excited..."

Kiyokawa Izumi offered a casual explanation, exuding an air of resistance to conversation.

Seeing this, Urokodaki Sakonji stopped asking further questions.

It's normal for some things to be different.

Just like his and Tanjiro's noses, as long as they're not demons, everything is fine.

……

After a quick meal, Kiyokawa Izumi left the cabin and went to the back mountain.

Passing through countless tall, slender trees, in the distance, one could faintly hear the sound of hard objects colliding.

At this point in time, Tanjiro was probably trying to break the boulder.

"Mr. Kiyokawa Izumi, are you awake? How are you feeling?"

Noticing the commotion behind him, Tanjiro sheathed his Nichirin Blade and asked enthusiastically.

"fine."

Kiyokawa Izumi wasn't deliberately acting aloof or pretending to be an expert.

His gaze was already drawn to the boulder in front of him, and unable to concentrate on anything else, he stared blankly at the boulder.

A colossal boulder, far taller than him and too heavy for one person to encircle, appeared before him—are you kidding me? Could this thing really be cut in half with a knife?

Is it reasonable?

Is it scientific?

The original owner didn't have any of these during training; it was just very basic physical training and sword-wielding training.

There was no such thing as cutting down boulders.

"Thanks……"

Kiyokawa Izumi suddenly snapped out of his daze and looked around.

Just now, it seemed like someone was thanking him?

The sound was extremely faint; it was almost inaudible unless you listened very carefully.

He almost thought it was an illusion caused by his drowsy brain.

"Because of the Hand Ghost? There's nothing to thank me for. At that time, I had nowhere to retreat and no other choice."

Kiyokawa Izumi, who had a rough idea of ​​what was going on, muttered to himself.

"Don't worry, I won't tell Mr. Urokodaki about these things."

If that person knew that his disciple's death was related to him, he would probably feel extremely guilty.

"Mr. Kiyokawa Izumi, are you... talking to me?"

Looking at the newcomer with some confusion, Tanjiro subconsciously glanced around, but saw nothing.

At this point in time, it seems he hasn't met Sabito yet.

"Can I try?"

Looking at the giant rock in front of him, Kiyokawa Izumi asked with a smile.

"Of course you can, but are you really alright?"

"This is nothing."

Kiyokawa Izumi wanted to give it a try, not because she wanted to show off in front of the protagonist.

I just couldn't contain myself.

Recalling the contradictory feeling of Urokodaki Sakonji wielding his sword—so light it seemed to cut through anything, yet so capable of striking anything—he felt a sudden urge to try it himself.

"Mr. Kiyokawa Izumi's scent has changed..."

Tanjiro, standing to the side, sniffed the air and then suddenly turned his head, feeling as if many eyes were watching them from not far away.

Is it just my imagination?

He was somewhat puzzled.
