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

Chapter 423 There's no more medicine to turn people into humans.

“Tamayo, you said…” Yuko stood at the door, still elegantly holding a teacup in her hand, “Should I swallow it?”

Tamayo blew a light breath, took a small sip, and then slowly looked up: "Didn't you already throw up?"

"But I'm thinking, how can it be called gastric lavage if you don't swallow it?"

Tamayo rubbed her temples lightly. "I think you should stop torturing yourself. Yushiro is going to get angry."

Yushiro said expressionlessly, "I'm already angry."

"Eh? Why?"

"..."

"Yuko, sit here," Tamayo gestured to the seat in front of her.

Yuko sighed, "Fine."

Although she still felt very uncomfortable.

Seeing her listless appearance, Tamayo couldn't help but say speechlessly, "I'm telling you, if it's broken down completely, doesn't that mean your body is completely clean?"

Yu Zi had just sat down when she heard this and paused for a moment, then her eyes lit up: "What you said... seems to make some sense!"

Tamayo breathed a sigh of relief. Fortunately, the child was still easy to fool and didn't get too hung up on it.

"In that case, I'll head back now." Yu Zi rubbed her face.

Although she is a ghost and doesn't need to sleep or rest, lying down still consumes less energy than standing.

Yuko these days seems to be able to sleep for days on end.

As soon as Yuko stood up, Tamayo grabbed her arm: "Wait, I have something to tell you."

"Huh? What? If it's because you're grateful that you want to marry me or something, then forget it," Yuko yawned. "Otherwise, Yushiro will get angry."

Upon hearing the first half of the sentence, Yushiro's face first turned angry, but upon hearing the second half, his ears began to turn purple.

Tamayo opened her mouth, but had no answer.

She strongly suspected that the child was retaliating for what she had just said.

Not a single word was changed.

Tamayo was silent for a moment, then suddenly said, "We're out of the human-transforming medicine."

“Hmm.” Yu Zi gave her a strange look.

She was well aware that the human-transforming drug was gone; after all, it was the last resort against Muzan, and Tamayo certainly wouldn't hold back.

But... if it's gone, it's gone, it's not like it's impossible...

Tamayo maintained her calm expression: "I'm afraid it will be difficult to make one in the future."

"Huh?" Yuko was slightly taken aback. "Why? I haven't turned back yet, have I?"

“Strictly speaking, it’s not just you who can’t turn back; Yushiro and I can’t turn back into humans either.”

Yuko explained, "No, that's not what I meant. What I meant was, I'm still a ghost, so you can continue using my blood to research the human-transforming drug, right?"

For some reason, she started to panic.

“That’s the problem.” Tamayo pursed her lips, seemingly with a hint of apology, “The human-transforming medicine contains your blood and Muzan’s blood.”

"And Muzan is already dead."

"You mean you're out of stock?"

Tamayo nodded.

Yuko's pupils dilated in shock: "Why didn't you say so earlier? Until just now, we could still take from Muzan's body..."

"Hadn't he already become human by then?"

Yu Zi panicked. "Don't scare me."

Yuko desperately wanted to see a hint of joking in Tamayo's expression, but all she could see was the unbearably heavy truth.

Yuko, unusually, tensed up and spoke urgently: "Then you should have told me sooner, before Muzan turned back into a human..."

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

"I'm sorry, I didn't expect Muzan to be able to overcome sunlight." Tamayo lowered her eyes slightly and bowed her head apologetically.

Yuko's mind was a complete blank. She rested her hand on her forehead and, after a long while, replied in a slightly weary voice, "No, it's my fault..."

"Muzan overcame the sunlight because of me."

The incident happened so suddenly, let alone Tamayo, no one could have thought of everything beforehand, right?

Yushiro was starting to lose his voice. Although he found it annoying that this woman was yelling at Lady Tamayo, this was definitely not a situation that anyone wanted to see.

It must be said that although this woman is sometimes quite annoying, Lord Tamayo really likes her.

However, if we're talking about who has been with Lady Tamayo longer, he wins.

What? Ikuko spent more time with Tamayo?

Since there's no way for him to turn back into a human, it must be because he's been in that state for much longer.

Tamayo sighed. She had actually guessed it, because she couldn't think of any other reason.

Surely it couldn't be that Muzan's will to not die allowed him to overcome the sunlight?

That's too ridiculous.

Tamayo changed the subject: "There's no need to be too sad, there are still ways."

Yuko suddenly looked up.

“First, Yuko, you are now a perfect being who has surpassed Muzan.”

Yu Zi sweated and waved her hand awkwardly: "No... that was just to provoke Muzan."

What perfect being? She doesn't actually have that kind of shamelessness.

Tamayo smiled and shook her head: "Continue studying your blood; perhaps we can find a way to help us turn back into humans."

Yu Zi gave a wry smile: "Are you just trying to comfort me?"

"Of course not. My research on your evolved blood is still incomplete. I believe there will be new discoveries." Seeing that her mood had improved somewhat, Tamayo smiled and said, "Secondly, there is another way to make us...die."

Ikuko noticed Tamayo's meaning: "Die? Doesn't that mean turning back into a human?"

Tamayo shook her head: "It was Ikuko who gave me this inspiration."

"?"

"It's a hunger strike."

“What kind of inspiration is a hunger strike…” Yu Zi paused for a moment, “You’re not going to talk about what I did before, are you?”

“Yes, otherwise how could I say that you were the one who inspired me?” Tamayo pursed her lips. “Ikuko should know that too, right?”

"Ghosts are not truly immortal."

"Just like Muzan, he too will be consumed by the aging potion."

"The immortality of ghosts is actually only based on having sufficient physical strength... that is, sufficient blood and food."

Yu Zi's eyes lit up, and she clapped her hands: "Now that you mention it, it does make sense!"

Tamayo nodded: "If it were me and Yushiro, and we stopped eating and drinking from now on, we'd probably die in a few decades."

"Wait, decades?" Yu Zi's scalp tingled. "Your level of skill takes decades? What about me?"

Since she became a demon in the Warring States period, she has never been able to eat her fill. After separating from Tamayo, she has not eaten any blood food. Even so, she has survived to this day.

Not to mention, she also consumed so much of Muzan's flesh and blood during the final battle.

She's exhausted, but she feels much better than she did before she met Tanjiro!

She's going to live for hundreds of years more?

and many more!

"Consuming stamina..." Yuko suddenly realized the key information, and a look of joy appeared on her face. "As long as I can consume stamina quickly, it'll be fine, right?"

"If we could use those potions given to Muzan..."

“It will be very painful,” Tamayo suddenly said.
