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

While the atmosphere within the Demon Slayer Corps was peaceful, the Infinity Castle convened another meeting.

“Infinite Castle… I’m here… Brother, have any Upper Moon demons been killed?” The stunningly beautiful white-haired girl with the words “Upper Moon Six” etched in her eyes stared in astonishment at the intersecting spaces before her.

Upper Moon Six - Daki.

Hearing her murmur, strange flesh suddenly grew from her fair back. In the blink of an eye, an ugly figure clung to her fair back.

The figure had dense black spots on his face. Although he was tall, he was thin as a rake. His back was hunched over like that of a seventy-year-old man. Although his arms were relatively broad, his waist was so thin that it seemed as if it would break at the slightest touch.

Upper Moon Six - Gyutaro.

These are twin ghosts.

Gyutaro scratched his face, his voice hoarse, and said, "The Upper Moon... I wonder who it is..."

Daki was overjoyed: "It doesn't matter who it is, this way we have hope of being promoted."

Gyutaro slapped her on the head: "Idiot, Lord Muzan must be very angry. You can't just say things like that."

Although both Upper Moon and Lower Moon meetings are held in Infinity Castle, they are fundamentally different.

The lower string is, at best, a consumable item that can be discarded at any time.

The Upper Moons, on the other hand, are Muzan's confidants. They are responsible for finding the Blue Spider Lily, gathering information on the Demon Slayer Corps, and killing the Pillars. Therefore, the atmosphere during meetings between the two sides is completely different.

The Lower Moons were basically trembling with fear and dared not speak, while the Upper Moons were much more relaxed. As long as you didn't intend to betray Muzan, Muzan was very tolerant.

Following the pipa player's music, the two arrived at a platform, where they saw what lay before them.

An old ghost with a bulge on its head, timidly hiding in a corner.

Upper Moon 4 - Half-Tengu.

An asymmetrical teapot.

The fifth of the Upper Moons – Jade Pot.

There was also a handsome young man with short, white oak hair who greeted them with a smile.

Upper Moon Two - Douma.

Gyutaro lowered his head in a hoarse voice: "Lord Doma."

The twin demons respected Doma quite a bit, after all, he was the one who led them onto the path of demons.

If it weren't for Doma's help, my sister would have died long ago.

No matter how many times he could do it all over again, he would still choose to become a ghost.

"Oh, so it wasn't you guys." Douma smiled, his expression quite amiable. "I thought you were the ones who got taken down~"

Gyutaro, Daki: "..."

It makes them seem weak.

Doma opened his seven-colored eyes and looked around in confusion, as if searching for something: "If that's the case, could it be Lord Akaza?"

“How could this be…” Douma’s eyes flickered, and two tears fell with a sorrowful expression. “King Akaza is my best friend…”

"..."

“Oh, this is…” A strange figure emerged from the asymmetrical pot, and Yu Hu looked at Tong Mo with a face full of embarrassment.

He really wanted to say, 'There are only a few of them here, so there's no need to put on such a show,' but Gyokuko was still rather untrustworthy to Doma.

Other people are easy to talk to as long as you don't mess with them, but this guy is different.

This guy is a lunatic; he might do something outrageous.

As he cried, Doma suddenly perked up and exclaimed in shock, "If it's not Lord Akaza, then could it be Lord Kokushibo?"

"how come……"

Is he going to say that Lord Kokushibo is also his best friend?

The ghosts were ashamed.

Despite his misdeeds, Douma held a rather high position among them.

Fortunately, there was a straightforward Nakime who said, "No, Upper Moon One was the first one summoned by Muzan."

"I... am here..." In the misplaced space, behind a curtain, a majestic voice emanated, making one's heart tremble.

Kokushibo's appearance silenced the demons who had been shouting as before.

Upper Moon One is a fierce demon that has remained unchanged for hundreds of years since the establishment of the Twelve Demon Moons system.

It can be said to be the demon closest to Lord Muzan.

Calling him merely a subordinate is no longer appropriate; even Muzan himself refers to him as a 'collaborator'.

This honor is something no other ghost can achieve.

Among all the demons, only the ever-unreliable Doma remained unmoved, a faint smile on his face.

"So, it really is Lord Akaza?"

"what a shame……"

"Nakime, where is Lord Muzan?"

The ghosts felt a chill in their hearts; if Akaza were dead, things would be in serious trouble.

That's one of the top three Upper Moon demons; the boss must be furious.

The twelve ghost months generally do not occur together unless one of them is missing.

"You seem quite happy, Doma." A dignified voice rang out softly.

Douma turned his head with a smile: "How could that be? I'm very sad~"

"Lord Muzan!" All the demons knelt down in unison.

Dressed in a black suit, Muzan Kibutsuji gazed calmly at the assembled demons with his crimson eyes.

"The crescent moon has waned, and Akaza is dead."

really!

The ghosts were terrified; who could it be...?

Kibutsuji Muzan raised his eyes slightly and went straight to the point without any preamble: "Kuroshibo, this time I need you to take action personally. Any problems?"

They actually sent Upper Moon One to make a move?

That seems normal, considering even Akaza wasn't a match for him...

Kokushibo lowered his head slightly: "Yes, sir."

"Once you confirm this woman's information, bring me her head." Muzan's calm voice rang out, as he casually sprinkled a drop of blood.

Kokushibo respectfully swallowed the blood drop, and the outline of a human figure gradually appeared in his mind.

Who?

Kokushibo was somewhat uneasy.

Before he could think any further, the figure gradually became clearer.

Kokushibo's body trembled for a moment, and all six of his eyes quivered slightly.

"?" The ghosts, sweat dripping from their foreheads, looked over in surprise.

What exactly did you see?

Even this old relic showed that kind of expression.

Is the person on the other side some kind of three-headed, six-armed monster?

"Do you understand now? That's why I want you to go in person." Muzan's expression remained calm, as if he had already anticipated Kokushibo's reaction.

"That monster...and its successors..."

Before Muzan could finish speaking, Kokushibo suddenly uttered an unfamiliar name.

"Ikuko..."

Muzan was slightly taken aback. Who?

The ghosts were also astonished. In their memory, this guy was a very old-fashioned person, a true antique, with the hierarchy of superiors and inferiors ingrained in his bones.

If I wasn't truly stunned, I would never have interrupted Lord Muzan.

Muzan frowned slightly: "What do you want to say?"

Muzan has the ability to read the minds of demons, but he will not actively try to read the mind of Kokushibo.

Mind reading means he doesn't trust other demons, but he trusts Kokushibo completely.

“This person…” Kokushibo’s heart, which had been calm for hundreds of years, was suddenly struck by a boulder, splashing up a pool of water, “…is my sister…”

"Sister?" Douma blinked. "Lord Kokushibo, are you seeing things?"

How old are you? If your sister isn't a ghost, wouldn't she be nothing but bones by now?

Among all the Upper Moons, only this guy dared to utter a sound in the face of this serious situation.

Didn't you see the serious expressions on the boss's and second-in-command's faces?
