Demon Slayer: The Journey That Began When I Became Yoriichi's Sister

there?

Following the direction Obanai Iguro pointed, Tengen Uzui looked ahead and saw a ruin standing precariously, blocking out the view behind the houses.

Isn't that the woman fighting Upper Moon One over there?

The Twin Demons are quite powerful; even with the four of them working together, they couldn't afford to be distracted by what was happening next door.

But deafening noises could often be heard coming from next door, along with the sounds of large numbers of houses collapsing.

Uzui Tengen glanced at Yuko subconsciously and found her playing a game of clapping with Nezuko as if nothing was wrong.

Out of curiosity about the destructive power of Upper Moon One, Tengen Uzui got up and walked towards the place where the two had just fought, with his three wives quickly following behind.

Obanai Iguro frowned and followed.

Upon reaching the street corner, Uzui Tengen noticed that the house he had just seen was now reduced to a single wall, with bright sunlight streaming through the empty paper windows.

"What is this...?"

As the group passed through the house, the scene before them suddenly opened up, and a look of shock quickly spread across their puzzled faces.

The wide street surface was marked with terrifying sword marks, like the claw strikes of a giant beast.

A wide trench, more than a meter wide and over half a meter deep, was dug into the center of the site, leaving a large pit several meters wide, cracked open like a spider web.

The surrounding forest of houses, which had been like a sea of ​​trees, was now as if it had been hit by a powerful tornado, and only a few ruins remained standing in the ruins.

"Eek!!" Suma bit his hand, his body trembling.

Mu Xu and Chu He were also speechless with shock at the sight before them.

What the hell is this?!

Obanai Iguro approached from behind the group and said calmly, "It's amazing that you can still be alive and kicking after such an attack."

His one gold and one green eye turned as he looked at Yuzui Tengen.

very curious.

Judging from the marks on these people, they had been through a difficult battle, but...

Faced with this level of combat, whether it was Uzui Tengen or anyone else, they all only looked tired, but their bodies did not suffer any damage.

No, it was more like a flawless pass, leaving Obanai Iguro somewhat bewildered.

Looking at this almost illogical scene, Yuzui Tengen took a deep breath and shook his head: "No, if I were to face this kind of attack, I probably wouldn't even have any bone fragments left."

"That's...?" Obanai Iguro narrowed his eyes. Was it that woman?

He wasn't particularly fond of the good ghost who claimed to be the founder of Snow Breathing and had survived since the Warring States period.

However, it cannot be denied that with that woman's help, the Demon Slayer Corps has successively killed two Upper Moon Demon Moons, who are elusive among the Twelve Demon Moons.

Even when he recently contacted Shinazugawa and mentioned that woman, she couldn't say anything bad about him.

Ah, of course, in his view, there might also be a reason why Ikuko was Kanae's savior.

However, the woman's strength was undeniable, a fact that both he and Shinazugawa fully acknowledged.

Uzui Tengen explained calmly, "In fact, the first one we encountered was not Upper Moon Six, but Upper Moon One."

“…One?” Obanai Iguro’s eyes widened slightly. “Then where is this?”

Uzui Tengen nodded: "Yes, that's where Miss Yuko fought him."

Obanai Iguro tilted her head: "Miss Yuuko? When did you become so easy to talk to?"

"Didn't you used to really dislike that woman?"

"Shut up!" Yuzui Tengen's face darkened.

You'll know once you have an argument with her; her sarcastic tone is simply unbearable.

If you don't back down, she can argue with you until you have a splitting headache.

Suma tugged at Uzui Tengen's sleeve and shook his head: "You can't dislike Miss Yuko, she's your benefactor."

Uzui Tengen: "..."

Obanai Iguro looked at her in confusion: "Benefactor?"

"Yes, yes, back then, Lord Tengen was bleeding profusely, it was terrifying. If it weren't for Miss Yuko's help, Lord Tengen would have split open." Suma nodded and gestured.

"..." Obanai Iguro paused for two seconds, then pointed at Tengen Suma and asked, "Is your wife alright?"

"Don't you dare insult my wife!"

"Who are you calling mentally unstable?!"

"Don't say that about Suma-chan!"

"..." Obanai Iguro once again experienced the feeling of being outnumbered and powerless, feeling as if he had been fed a mouthful of dog food.

After a while of commotion, Uzui Tengen explained, "I was the first person to collide with that monster."

"So, what do you think? The opponent's strength?" Obanai Iguro looked at the ruined city.

Uzui Tengen's expression grew more serious. "This is not an opponent that a human could defeat in a one-on-one fight."

He couldn't help but shudder at the thought of what had happened.

In fact, this was a rather cautious statement. Uzui Tengen's real thought was that the monster was simply beyond human capability to defeat.

"Just standing in front of him makes one tremble with fear. Those below the Pillar level don't even have the courage to face him."

"No, it should be said that Pillar's fighting strength is simply not enough in front of the opponent."

"Even Mr. Himejima... I think so too..."

"I was as weak as a child in front of him. I wouldn't last a single round if we faced each other head-on. If he hadn't never intended to fight seriously in the first place, I would probably be dead by now."

That monster must have been targeting Yuko from the start, which is why he escaped unharmed.

Hearing Tengen Uzui's calm words, Obanai Iguro fell silent as he looked at the seemingly man-made ruins.

About four or five years ago, before he became a Pillar, Kanae Kocho encountered Upper Moon Two and almost died at his hands, concluding that he was just playing around.

A few months ago, during the battle on the Mugen Train, Kyojuro Rengoku encountered Upper Moon Three and concluded that if he had faced it alone, he would not have survived.

Now, with Tengen Uzui encountering Upper Moon One, things have become even more outrageous.

Some even conclude that acting like a child in front of the other person and remaining calm in their presence is a luxury.

Is the difference between the upper and lower sections really that big?

Uzui Tengen, who could join forces to behead Upper Moon Six, couldn't even last a single round against Upper Moon One.

There's no way to refute it; the level of destruction is terrifying just to stand on the ruins.

It's completely unimaginable what it would be like to fight the other side.

No wonder the Demon Slayer Corps has been unable to kill Muzan for over a thousand years; such fighting power is truly despair-inducing.

Perhaps... only by using human lives to build a foundation can there be even a sliver of hope for victory.

but……

Can anyone tell him why these Upper Moons all like to play this game? Are they out of their minds?
