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

In the hundreds of years since the birth of breathing techniques, those who have been able to independently develop breathing techniques and sword forms are all geniuses.

Even among the five fundamental breathing techniques, the sword forms that have been passed down over the centuries number at most only a dozen or so.

The fact that a descendant possessed such talent at the young age of fourteen stirred a long-lost sense of admiration in Kokushibo's heart.

The last time I felt this way was when Akaza launched a positional battle against him.

He had originally hoped that Akaza would bring him more happiness, but he never expected to meet Ikuko.

It wasn't that he looked down on Akaza; Akaza certainly had talent, otherwise he wouldn't have been able to become Upper Moon Three, but that was all.

The fact that he was surpassed by Doma, who became a demon later than him, shows that his talent was not among the strongest, and he was far inferior to Ikuko.

One of the more presentable guys is gone.

However, there was nothing to regret for Kokushibo. Ikuko was still alive, and Kokushibo's heart, which had been calm for hundreds of years, began to stir again.

He wanted to prove himself to Yuko.

He is right.

……

Muichiro is undoubtedly a genius, but he is still too inexperienced.

The battle... no, it should be described as a one-sided attack. Kokushibo never drew his blade, but simply dodged with an air of nonchalance.

Muichiro frowned slightly, but continued his relentless attack.

Kokushibo lowered his eyes slightly. This child…

Is it that I'm stubborn or what?

With such an obvious difference in strength, shouldn't they understand it by now, no matter how much they struggle?

Kokushibo paused, as the slash that he could have easily dodged came straight for his neck.

A ripple appeared in Muichiro's usually calm eyes, but in the blink of an eye, he was annihilated by Kokushibo's own hand.

The sharp blade was held back by the not-so-tough fingers, unable to advance at all.

"The sword shape is quite good, but there's a slight stiffness in the transitions," Kokushibo commented, glancing down at the blade. "Isn't this your usual sword?"

His swordsmanship was impeccable, and his use of sword techniques was unparalleled. The only slight obstruction was in the transitions between movements.

The only possibility is that you haven't gotten used to the weapon yet.

Even a specially designed new weapon will feel completely different from the weapons you used before.

Not to mention that Muichiro Tokito just grabbed this weapon from the workshop.

Although the weapons are all of the standard samurai sword type, it is still unlikely that they can be used to their full potential.

This requires a certain amount of time to adapt.

Muichiro's eyes widened slightly. This guy... is so perceptive...

Just as he was about to draw his sword and step back, he suddenly noticed out of the corner of his eye that behind Kokushibo, Tetsuya Mori and Kotetsu were sneaking out of the woods and tiptoeing slowly toward the hut.

Muichiro's mind, which was usually devoid of ideas, went blank for a moment.

These two idiots... do they think that if they do that, the monster won't notice?

"Hurry up, go in!" As if annoyed that Tie Xuesen was dawdling at the door, Xiao Tie nudged his butt.

What on earth is going on?

These two people...

Muichiro's eyelids twitched slightly twice.

Kokushibo, who was pressing his fingertips against Muichiro's blade, turned his head slightly. He no longer wanted to care about those two rats. Wouldn't it be better to just run away like rats?

To his surprise, the other party not only did not run away, but also kept jumping around right under his nose.

Seeing Kokushibo turn around, Muichiro knew something was wrong and kicked off with both feet, launching himself into the air to slam into Kokushibo's chest.

Kokushibo's attention was interrupted in time, and he raised his hand to block it.

Muichiro successfully used the force to retreat, glancing down at Kokushibo's steps, which remained completely still.

I can't see a way to win.

Kokushibo said calmly, "You seem to care quite a bit about those two humans."

"This is not a good habit."

Yuko ended up in danger because she protected unnecessary humans.

Muichiro got into a fighting stance: "That's why you can't understand. A demon is a demon; it only knows how to harm others indiscriminately."

Even Muichiro's desire to protect others remains unchanged.

There are stronger people in the village than him, so don't worry, he'll hold off this monster here.

pretty good.

……

Without any warning, the tall figure suddenly appeared.

Muichiro's pupils constricted sharply, and his heart seemed to stop beating. Even though he reacted quickly and drew his sword to slash, Kokushibo gave him no chance to show off. He snatched the Nichirin Blade and grabbed Muichiro by the collar, slamming him to the ground.

"Ugh~" The pain from his back hitting the ground made Muichiro let out a painful howl.

"Muichiro's 'Mu'..."

In the moment his mind went blank, it seemed as if a voice was calling in his ear.

Who?

Muichiro's mind went completely blank.

Kokushibo looked down at him and said, "My descendant, become a demon and serve Lord Muzan."

Kokushibo held back after all; otherwise, he could have killed Muichiro with that single blow.

He sacrificed too much for Muzan Kibutsuji's regime.

Before Muichiro could catch his breath, a slight noise came from behind Kokushibo.

"Go! Yoriichi Zero!"

Even though their actions seemed blatant to Kokushibo, he couldn't help but feel a jolt of unease upon hearing the name Yoriichi.

Kokushibo turned around, and a six-armed puppet, wielding six Nichirin Blades, steadily attacked him.

Kokushibo's eyes narrowed slightly.

This scene reminded him of some unpleasant memories.

Taking this opportunity, Xiao Tie quickly waved to Muichiro: "Stand up!"

Muichiro didn't have time to think about the figure that appeared in his mind, and he forced himself to stand up despite the pain in his body.

"Lord Tokito! The sword!"

Tetsuka Mori quickly handed the sword he was holding to Muichiro.

"You two..." Muichiro instinctively took the sword.

Xiao Tie lowered his voice and called out, "Quick, while Yoriichi Zero is holding this guy off, let's run!"

That brat... he absolutely refused to give me the keys when I asked him to...

Something seemed to stir within Muichiro's heart.

but……

Block?

Muichiro glanced to the side and saw that the monster who had never drawn his sword when facing him... had drawn it.

It was a demonic blade, reeking of decay and covered with hideous eyes.

"Breathing of the Moon, Third Form: Aversion to the Moon, Erosion!"

Two purple crescent-shaped slashes emerged from the blade, their surfaces covered with countless tiny crescent-shaped markings.

The two slashes arrived at Yoriichi Zero's front almost simultaneously, one striking straight at Yoriichi Zero's body, the remaining force of the sword energy cutting through the small house behind Yoriichi Zero.

With a single shot from below, it shattered Yoriichi Type-0's head, then sliced ​​through the large tree behind it, and swayed towards the sky.
