All-Around Support Healer

"That's how it is. Not only have the injuries in my lungs healed, but my entire body's strength has increased. It's like I've been reborn."

Yuko said, flexing her bicep, her body language quite expressive.

Still the same as before...

Yoriichi first smiled with relief, then said with a serious expression, "Yuko."

"Hm?"

"Don't let this power go to your head. Demon powers must be used with caution."

Seeing her older brother's serious demeanor, Yuko also suppressed her smile and replied solemnly, "Mm, I understand."

Overusing demon power does indeed lead to a major problem.

That problem is weakness.

Once a demon is weak, the desire to eat will intensely occupy their entire mind.

And demons, in pursuit of power, will eat humans.

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

Kokushibo himself chose to become a demon to pursue power, to become stronger than Yoriichi, abandoning his humanity.

With Kokushibo's precedent, Yoriichi naturally became even more attentive to Yuko.

However, just mentioning it now made her drool a little.

Seeing the saliva dripping from his sister's lips, Yoriichi was momentarily stunned.

Yuko quickly sucked it back in, looking at Yoriichi with a parched expression.

"Um, Brother..."

"Hm?"

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

"Then I'll make something for you..." Yoriichi started to get up, then suddenly realized, "What... what do you want to eat?"

Yuko looked at him with fervent eyes.

Yoriichi: "..."

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

It had to be said, Kokushibo had taken good care of her.

Fearing she would be weak and hungry after becoming a demon, he had deliberately left Namiko there.

He hadn't even killed her directly, fearing she would eat something not fresh.

So it wasn't without influence after all?

Yoriichi's eyelids drooped slightly, and he sighed, "Yuko, we can't be sure yet if you're different from other demons."

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

At least he needed to see it.

Yuko blinked in surprise, then stated matter-of-factly, "I don't have anywhere else to go."

"Besides, I'm counting on you to teach me swordsmanship and get revenge on Kokushibo."

"That bastard kept grabbing my neck and asking if I wanted to become a demon," Yuko's eyes turned dangerous as she said fiercely, "One day, I'll beat him until he's spitting teeth!"

Yoriichi: "..."

Well, it seems she hasn't changed at all.

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

This small action, despite carrying no pressure or aura, caused Yuko's entire body to stiffen subconsciously.

The demon lord's cells are acting up inside me again.

Yoriichi paid no mind to his sister's reaction and lightly cut a gash on his hand.

"Is this okay?"

As the saying goes, food is paramount.

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

"Yes, yes!" Yuko nodded vigorously, stepping forward to cup her hands and catch the blood.

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

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

"Nothing." Yuko shook her head.

She had just thought of the meme about Yoriichi being an avatar of the sun god, and wondered if she would be burned to death if she drank his blood.

Such a thought had inexplicably popped into my head.

Fortunately, it wasn't that absurd.

It tasted delicious, like finding water in a drought.

Although it definitely couldn't compare to eating people, at least she'd had a little snack.

This life is unbearable, too much suffering.

If immortality meant living like this, she'd rather not have it. The feeling of an empty stomach was too awful.

I wonder what Miss Tamayo is doing right now.

Yuko thought that after Miss Tamayo was saved by Yoriichi, she seemed to stop eating humans. When she met Tanjiro later, Tanjiro hadn't smelled the stench of a demon on her.

Miss Tamayo seemed to survive on human blood, and it was relatively easy for her to obtain it given her identity.

Should she go and seek refuge with Tamayo then?

Work a bit to earn some food.

Miss Tamayo is a doctor, after all, so she's part of the system, right?

It's definitely better than being an unemployed bum like her, only able to freeload at home.

Sigh.

Yuko sighed.

Yoriichi tilted his head, watching his sister's expression shift, finding it inexplicably cute.

If one ignored the blood on her lips and hands.

Yoriichi's blood barely filled Yuko's stomach, and some color returned to her face.

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

"Brother, how about I show you a magic trick?"

"Magic trick?"

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

Yoriichi said calmly, "This blade isn't actually suited for Snow Breathing."

Yuko nodded. "I know."

Breathing styles and sword forms were complementary, and the performance of a sword form often depended on the blade.

This blade was the Nichirin Blade Yuko had been using before she had mastered Snow Breathing when she first joined the Demon Slayer Corps.

It was more suited for the five major breathing styles.

Snow Breathing was derived from Wind Breathing, but it also incorporated elements of Lightning Breathing, Sun Breathing, and others, making it the most complex breathing style currently.

Ordinary blades simply couldn't match it.

Furthermore, with Yuko's lung damage, she hadn't been able to go on missions, so her Nichirin Blade didn't need to be replaced.

Thus, she had used this blade until now.

Yuko used the broken blade to cut a gash on her own wrist. Yoriichi opened his mouth, wanting to say something but stopping himself.

"Brother, your hand."

Yoriichi obediently held out his hand.

Yuko smeared her blood onto Yoriichi's wound, and the wound began to heal at an astonishing speed.

As Yoriichi watched in surprise, the wound on Yuko's wrist also healed. She explained, "This is the Blood Demon Art I awakened."

"It allows for rapid healing of injuries."

"It can even regenerate severed limbs."

A hint of imperceptible confidence entered Yuko's voice.

This power would definitely be useful in the future.

If humans could have the same regenerative abilities as demons, what advantage would demons have?

She didn't know if it was the peculiarity of the Blue Spider Lily or if Kokushibo had injected enough of Muzan's blood into her.

Whether it was the regenerative power from the Blood Demon Art or Yuko's own recovery ability, both far surpassed those of ordinary demons.

Seeing her wound heal, Yoriichi nodded slightly. "It is indeed a powerful ability."

"Right? And that's not all it can do." Yuko dragged her palm across the Nichirin Blade, coating the blade in a layer of blood.

The blood spread unnaturally along the blade, turning it almost uniformly crimson.

"My blood can also enchant weapons, enhancing the power and range of sword forms."

This was somewhat similar to Kokushibo's Blood Demon Art. Although not as convenient as his, it wasn't far off.

More importantly, her ability could be used on others.

She, Tsugikuni Yuko, was an all-around support!
