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

late at night.

Yuko woke up from her dream with a start, feeling uneasy. She had forgotten what she had dreamt about, but she hadn't felt this way for many years since she became a ghost.

Demons don't actually need to sleep, but Yuko hasn't lost her human emotions; she's gotten used to it.

Humans who are transformed into demons generally gradually lose their human emotions, especially those who have just been transformed into demons, whose minds are often filled with only the thought of eating people.

After they have eaten people, their rationality will gradually return. The more people they eat, the more their intelligence will approach that of a normal person.

The reason she didn't experience this condition was mostly due to the blue spider lily, plus the fact that Iwakatsu injected enough Muzan's blood into her body.

Given the relationship between Iwakatsuna and Muzan, it is quite possible.

When Yuko woke up, the unease in her heart had not yet dissipated, as if something was about to happen, or... was happening.

The tightness in my chest was exactly the same as when I dreamt that Yan Sheng had turned into a demon.

Yuko adjusted her breathing, stepped out of the room, and tried to relax.

The open door came into her view, and Yuko quickly sensed Yoriichi's presence.

No.

Yuko was startled for a moment. She went to Yoriichi's door and knocked. When she received no response, she immediately pushed the door open and went in. Sure enough, no one was there.

Where can an 80-year-old go at this time?

But for some reason, her sixth sense gave her the answer from outside the city.

A crimson blood moon hung in the sky, and the pagoda outside the city was close at hand, making Yuko's unease grow stronger.

Arriving at the open space in front of the pagoda, the ground reflected dappled moonlight, and a familiar smell of blood wafted into Yuko's nose.

Iwakatsu...

Her heart skipped a beat.

Yuko's gaze extended further ahead, and under her excellent eyesight, she saw a pile of tattered pieces of cloth scattered there.

Yuko's pupils suddenly contracted, and her breath caught in her throat.

She walked over with somewhat heavy steps, and what came into view was Yoriichi's body, which had been cut in half at the waist.

Yu Zi froze for a moment, then her wine-red eyes instantly turned into golden vertical pupils, with hideous blood vessels covering her eyeballs.

Yuko gritted her teeth and forced out two words filled with resentment.

"Yan Sheng!"

Even when she betrayed her lord and became a demon, even when she was transformed into a demon by Iwakatsu, Ikuko never held a grudge against him.

Only this time...

This is your own brother, born of the same father and mother! Has he lost his humanity after becoming a ghost?!

Yu Zi clenched her fists so tightly that she didn't even notice the cold blood dripping from her palms as her nails dug into her flesh.

In her extreme anger, her wine-red hair began to show signs of turning white.

……

"Ikuko..."

Suddenly, a gentle voice sounded from behind her.

Yuko subconsciously turned around.

Her long, fiery red hair fluttered in the air, and her whole body radiated a faint white light. Yoriichi, who looked like a twenty-year-old youth, was looking at her tenderly.

Yuko was too surprised to speak, and just stared blankly at Yoriichi.

ghost?

No, it should be called a ghost.

Otherwise, there's no way to explain what she's seeing.

She remembered... Tanjiro seemed to have had a similar experience.

“Brother…” Yu Zi’s eyes were filled with tears as she gritted her teeth in grief and indignation, “That bastard, I will definitely cut off his head!”

She actually dared to think she could change that disloyal and unjust person!

it is ridiculous!

Yoriichi stared at her for a while, then suddenly reached out and stroked her head.

It has no tactile sensation, yet it inexplicably makes you feel warm.

Yoriichi's gentle voice rang out.

"it does not matter."

Just like when she comforted Yoriichi back then.

"My time is running out, and from now on I'll have to rely on you alone." Yoriichi's tone carried a hint of reluctance.

Yuko took a deep breath, her eyes still glistening with tears, but she said with unwavering determination, "I will definitely cut off Muzan's head."

Yoriichi smiled gently: "If it's Yuuko, she can definitely do it."

Yuko opened her mouth as if to say something, but Yoriichi's body suddenly began to dissipate.

"Brother..."

She had barely begun to speak when she heard Yoriichi's voice.

"If you feel tired, you might as well stop and take a break."

Yu Zi's eyes flickered, and she seemed slightly lost in thought.

Yoriichi's smiling face disappeared into the air.

Standing there in a daze for a long time, Yuko solemnly collected Yoriichi's body and Nichirin Blade.

Yoriichi's flute, which he always carried with him, is missing; it must have been taken by Iwakatsu.

Yuko felt so disgusted she wanted to vomit.

Yoriichi did not leave any instructions on where he wanted to be buried, but Ikuko thought he probably wanted to sleep with Uta.

……

As winter approached, Yuko arrived at Tanjiro's house under the cover of night.

Things have changed. Tanji and his wife passed away many years ago, and Ikuko doesn't want to have any contact with their descendants, lest she add to her grief.

Heavy snow blocked the mountain pass, and when Yuko passed by Tanji's house, she was attracted by the firelight in the courtyard.

She hid in the woods at dusk and witnessed the descendants of Tanji wielding the Sun Breathing sword form.

The Breathing of the Sun has indeed been passed down.

Yuko withdrew her gaze, took Yoriichi's remains to Shi's grave, clasped her hands together in prayer, then dug up Shi's grave and buried Yoriichi's remains there as well.

……

She became a person again.

Unlike before.

She had nowhere to go back to.

Yuko wrapped Yoriichi's Nichirin Blade in white cloth and hid it at her waist, especially the hilt, which she wrapped tightly to prevent the demon from recognizing it.

It forms a pair with the snow-white demon blade at her waist.

The Nichirin Blade slays demons, and the demon's blade slays men.

……

With nowhere to go, Yuko wanders aimlessly across this land.

As night fell, scattered lights flickered from distant villages, and wisps of black smoke drifted in the sky.

During the Warring States period, numerous warlords vied for power, and war raged everywhere.

In this dog-eat-dog world, acts of burning, killing, looting, and massacring villages were not uncommon.

A strong aura of evil spirits filled her nostrils, and the aura came from more than one place.

It was obvious that the village, which had just been ravaged by war, had been taken over by evil spirits.

Over the years, Yuko had not encountered many evil spirits. Even during the Taisho era, evil spirits mostly existed only in legends and stories, and were used to scare children.

But now that she's encountered it, she won't ignore it.

As Yuko entered the village, she saw severed limbs and corpses everywhere.

In the face of war, the influence of evil spirits can only be described as insignificant.

Yuko did not linger; by now, the food could no longer sway her will.

Yuko walked toward the place where the ghostly aura was the strongest, which was an open space in the center of the village.

The further you go in, the more corpses you see along the way.

Animal bite marks also began to appear on the corpse.

Yuko knew that it wasn't an animal, but a demon.
