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

"That's how it is. Not only have my lung injuries healed, but I'm also much stronger. It's like I've been reborn."

As Yuko spoke, she flexed her biceps, displaying a rich array of body language.

It's still the same as before...

Yoriichi smiled with relief at first, then said seriously, "Yuko."

"Ok?"

"Don't let this power go to your head; use the power of ghosts with caution."

Seeing her brother looking so serious, Yu Zi also suppressed her smile and said solemnly, "Yes, I know."

Overusing the power of demons can indeed cause a major problem.

That is weakness.

When a ghost is weak, its desire to eat becomes so strong that it quickly takes over its entire brain.

Evil spirits, in their pursuit of power, also devour people.

No matter how you look at it, Yoriichi's concerns are valid.

Because Kokushikatsu chose to become a demon in pursuit of power, to become stronger than Yoriichi, thus betraying his identity as a human.

Having learned from Iwakatsu's experience, Yoriichi naturally paid even more attention to Ikuko.

But now, just mentioning it makes her drool.

Yoriichi was a little stunned as he looked at the drool overflowing from his younger sister's mouth.

Yuko quickly inhaled again, staring blankly at Yoriichi.

"That older brother..."

"Ok?"

"I haven't eaten anything for several days."

"Then I'll go make it for you..." Yoriichi was about to get up when he suddenly realized, "You... what do you want to eat?"

Yuko looked at him with intense eyes.

Yoriichi: "..."

Yuko clasped her hands together: "Blood! Please, I only need a little bit of blood!"

It must be said that Yan Sheng took great care of her.

Fearing that she would be weak and have nothing to eat after becoming a demon, they deliberately left Namiko there.

They didn't even kill her directly, for fear that she would eat something stale.

So it turns out there was some impact after all?

Yuan lowered her eyelids slightly and sighed, "Yu Zi, we still can't be sure if you're different from other evil spirits."

"So from now on you'll have to live with me."

At least let him see it.

Yu Ziwei was taken aback for a moment, then said matter-of-factly, "I don't have anywhere else to go."

"And I'm counting on you to teach me swordsmanship so I can avenge Yan Sheng."

"That bastard kept grabbing my neck and asking me if I wanted to become a ghost." Yu Zi's eyes turned dangerous as she said viciously, "One day, I'll beat him to a pulp!"

Yoriichi: "..."

Okay, nothing has changed after all.

Yoriichi picked up the Nichirin Blade beside him and drew the blade.

This small gesture, which carried no intimidation or imposing manner, made Yuko's whole body instinctively stiffen.

The scumbag boss's cells are causing trouble in her body again.

Yoriichi didn't pay attention to his sister's actions and gently made a cut on his hand.

"Is this okay?"

There's an old saying that goes, "Of all things under heaven, eating is the most important."

The desire to eat eventually suppressed the fear within Muzan's cells.

“Yes, yes!” Yu Zi nodded vigorously, stepped forward, and caught the blood in her palm.

Just as Yuko lowered her head to taste it, she suddenly stopped.

Yoriichi asked with concern, "What's wrong?"

"No." Yu Zi shook her head.

She was just thinking about the idea that Yoriichi was an incarnation of the sun god, and wondered if she would be burned to death if she drank his blood.

This thought just popped into her head for no apparent reason.

Fortunately, it wasn't that outrageous.

It tastes delicious, like a long-awaited rain after a drought.

Although it certainly couldn't compare to cannibalism, at least they got some snacks.

This is unbearable, it's too much suffering.

If immortality meant living like this, she'd rather not have it; the feeling of constantly being hungry was just too unbearable.

I wonder what Ms. Tamayo is doing now.

Yuko thought that after Tamayo was saved by Yoriichi, she seemed to have stopped eating human flesh. When she met Tanjiro in the future, Tanjiro did not smell the stench of demons on her.

Miss Tamayo seems to have survived by consuming human blood, and given her identity, acquiring these things would be relatively easy.

Should she go and seek refuge with Zhushi?

I'll do odd jobs to earn a living.

Ms. Hitotsuse is a doctor, so she should be considered part of the system, right?

At least it's much better than being an unemployed bum like her, who can only stay at home and sponge off her parents.

Ugh.

Yuko sighed.

Yoriichi tilted his head, watching his younger sister's ever-changing expressions, which were inexplicably adorable.

If you ignore the blood on her lips and hands.

Yoriichi's blood allowed Yuko to eat a little something, and her complexion regained some color.

Looking at the wound on Yoriichi's wrist, Yuko smiled mischievously.

"Brother, how about I perform a magic trick for you?"

"magic?"

Yuko picked up her broken Nichirin Blade and sighed, "It's been with me for so many years, what a pity."

Yoriichi said calmly, "This sword is actually not suitable for the Snow Breathing technique."

Yuko nodded: "I know."

Breathing techniques are paired with sword techniques, and the effectiveness of sword techniques is often inseparable from the blade.

This is the Nichirin Blade that Ikuko was already using when she joined the Demon Slayer Corps, before she had mastered Snow Breathing.

It is more suitable for the five breathing techniques.

Snow Breathing is derived from Feng Shui Breathing, but it also incorporates breathing techniques such as Thunder Breathing and Sun Breathing, making it one of the most complex breathing techniques currently available.

Ordinary blades simply cannot be matched.

Furthermore, since Ikuko's lungs were damaged, she never went on any more missions, so her Nichirin Blade naturally didn't need to be replaced.

So this knife has been used ever since.

Yuko used the broken blade to cut a gash on her wrist, and Gen opened her mouth as if to say something but then stopped.

"Brother, hand."

Yoriichi obediently took out his hand.

Yuko smeared her blood on Yoriichi's wound, and the wound healed at an alarming speed.

Under Yoriichi's surprised gaze, Ikuko's wrist wound had already healed. She explained, "This is the Blood Demon Art I awakened."

"It can quickly heal injuries."

"It can even regenerate a severed arm."

Yuko's words carried a hint of barely perceptible confidence.

This power will surely come in handy in the future.

If humans possess the same regenerative abilities as demons, then what advantage do demons have?

It's unclear whether it's the special nature of the blue spider lily or the fact that Iwakatsu injected a sufficient amount of Muzan's blood into her body.

Both the regenerative power brought by the Blood Demon Art and Yuko's own regenerative ability far exceed those of ordinary demons.

Seeing his wounds heal, Yoriichi nodded slightly: "It is indeed a powerful ability."

“Right, and it has more uses than just that.” Yuko ran her palm across the Nichirin Blade, the blade coated with a layer of blood.

Blood spread abnormally along the blade, almost uniformly turning the edge blood-red.

"My blood can also enchant weapons, increasing the power and range of swords."

This is somewhat similar to Iwakatsu's Blood Demon Art, although it is not as convenient, but not much different.

More importantly, she can share this ability with others.

She, Yuko Jikuni, is an all-around supermom!
