Demon Slayer: The Naruto Hashira is a pure villain!

"Alright, alright, stop shaking it, or I'll throw you down."

Yayoi clicked her tongue, freeing one hand to pull a folded note from the small cloth bag on its back.

The note was written in Tamayo's neat and beautiful handwriting. It said that there had been progress in the drug development and that she should definitely go to the headquarters research institute.

"Did Tamayo send you?"

"Meow."

"Stop barking like a dog! Can't you speak like a human being?!"

"Meow?"

The calico cat tilted its head and blinked innocently.

Having no other choice, Yayoi picked up the cat, turned around, changed direction, and hurried towards the Demon Slayer Corps headquarters.

When they arrived at the research institute, Tamayo was sitting at the lab bench fiddling with test tubes, while Yushiro was recording data beside her. Both of them looked a little tired.

Hearing the noise, Tamayo looked up, saw Yayoi, and nodded slightly: "Miss Kuwashima, you've arrived."

Yushiro ignored Yayoi completely and continued memorizing things.

Yayoi put Chacha-chan on the ground, pulled up a chair and sat down, getting straight to the point: "Speak, what is it? Why did you make this guy, who has no dignity as a male cat, come all this way?"

Tamayo put down the test tube in her hand, turned around, and looked more serious than usual.

"There are two pieces of news, one good and one bad."

"The good news is that the drug to turn ghosts back into humans has been successfully developed."

Yayoi raised an eyebrow.

It happened faster than she had expected.

"And the bad news?"

“Currently, the production of purified medicinal materials is limited; only three vials have been produced.” Tamayo’s voice was soft, yet every word was clear. “Yushiro and I don’t need this for the time being. Our bodies have been completely transformed, and Muzan’s cells cannot control our life or death. Even if Muzan dies, we will not dissipate with him.”

"Oh?" Yayoi tapped the table with her fingertip. "Then what's left is me, Mrs. Shizu, and Nezuko? Three sticks, just right."

Tamayo remained silent for a moment, then slowly shook her head.

"No. We must keep at least one dose to combine with the other three potions to create a potion that weakens Muzan. Injecting it into him during the final battle will greatly suppress his regenerative abilities and Blood Demon Art."

"So... there are only two?"

Yayoi stopped counting on her fingers.

Three sticks, minus one for Muzan, leaving two sticks.

It's not enough for three people.

"Hmm." Tamayo nodded, looking up at Yayoi with a clear gaze. "But even if there were enough potions, Miss Kuwashima, you might not use them, would you?"

Yayoi looked up, met her gaze, and chuckled, "Oh? What makes you say that?"

"Putting aside the fact that you've always disliked doing things with uncertain outcomes, the medicine takes time to take effect. Even if it succeeds, you'll revert to being an ordinary person."

"Your plan is to participate in the final battle against Muzan as a demon, right?"

Chapter 213 No Regrets for the Choices Made

Without the ability to regenerate at any time like a demon, and without the combined power of Thunder Breathing and Blood Demon Art, how could he possibly contact Nakime in the final battle, restrain Kokushibo, and directly confront Muzan?

When her thoughts were exposed, Yayoi was not angry; instead, she chuckled softly.

"It's a good thing that Ms. Tamayo is an ally. If you were a demon on Muzan's side, I would have a real headache."

Fortunately, Muzan was an idiot; he squandered a winning hand.

If Muzan, who has little brains, had a brilliant strategist like Tamayo by his side, that would be truly difficult to deal with.

"I am also very glad that Miss Kuwashima ultimately chose to stand on the side of the Demon Slayer Corps." Tamayo bowed slightly, her tone sincere.

She had seen too many ghosts, and was consumed by desire and instinct, becoming neither human nor ghost.

But Yayoi is different. Even after becoming a demon and losing her memory, she never lost her principles and pride.

Moreover, Yayoi's Blood Demon Art is truly troublesome.

If someone like that were on Muzan's side, the Demon Slayer Corps probably wouldn't have a single chance of winning.

“Miss Kuwashima, you still have a chance to back out.” Tamayo looked at Yayoi and advised her one last time, “If you don’t participate in the final battle, you might still have a chance to survive.”

There's no need to gamble everything.

Yayoi stood up and walked towards the door. "I will not regret my choice."

"Also, please keep this a secret, Miss Tamayo. Don't let anyone else know about the potion, except for the few of us. Especially... Sanemi."

Given Sanemi's personality, if he knew there were only two doses of the medicine, who knows what foolish things he might do.

They might even try to take Nezuko's share of the potion.

In this way, it is very likely that he will fall out with Sabito and Giyu before the big battle, which will only give Muzan an opportunity.

"Yes, I will." Tamayo nodded gently.

Yayoi didn't linger any longer and left the research institute before dawn.

Before dawn, screams echoed throughout the courtyard of the Wind Pillar's stronghold.

Sanemi swaggered around the front of the group like a demon, and if he saw anyone who was slow to swing their sword, he would lash out with the back of his blade, making the person shudder.

"You haven't eaten, have you?! At this rate, are you just waiting to be devoured by a ghost?!"

The team members all wore grimaces, gritting their teeth as they fought back against their partners, none daring to slack off.

Just then—

"Bang!"

The gate was kicked open, startling everyone in the yard and instantly bringing them to their senses.

Yayoi stood at the door, her white hair fluttering slightly in the morning breeze. Her red eyes swept over the people in the courtyard, and she frowned.

Where is the River of Immortality?

"Lord Naruto-Naruto?!"

Many team members recognized Yayoi and were stunned when they saw her.

Wasn't it said that Lord Naruhashi had already sacrificed himself? How... how did he come back to life?

Is the romance scam?

Before they could react, a figure rushed out from the depths of the courtyard like the wind.

Sanemi, carrying a teammate whose face was swollen from being beaten, hurried to the door. The moment he saw Yayoi, his eyes lit up.

That usual coldness and fierceness vanished instantly, and even his tone softened unconsciously.

"Yayoi, you're back."

"Throw away this ugly thing in your hand before you talk to me."

Yayoi glanced disdainfully at the team member he was carrying; the boy's face was swollen like a bee dog's, and his eyes were brimming with tears—it was an eyesore to look at.

Without hesitation, Shimi tossed the person into the ranks behind him, where several team members scrambled to catch him.

"Why did you suddenly come here?" Sanemi walked up to Yayoi, his gaze fixed on her face, unable to get enough of looking at her.

It's been almost two months since the two last met.

"I want to go to Jingqiao District, take me there."

Sanemi paused for a moment, then realized what she meant and agreed without thinking, "Okay."

"Lord Wind Pillar... what about us?"

Someone in the group asked cautiously, their eyes full of anticipation.

Lord Wind Pillar is busy, so... can you take a day off?

Just as Sanemi was about to say, "You can do it yourselves today...", a head popped out from over the wall next door.

Kōno Kōchin leaned against the wall, grinning brightly: "Don't worry about leaving it to your senior brother, Sanemi!"

"I guarantee I'll train your men thoroughly."

The team members in the courtyard instantly turned green.

The once popular Kaze Pillar, Lord Kamino, now finds himself surrounded by resentment.

So it's not a holiday, it's just a change to something even more troublesome, huh?!

Ignoring the wails of his teammates, Sanemi looked up and saw that the sun had already risen above the horizon and was about to shine on the doorway.

Sanemi's expression changed, and he picked up Yayoi and rushed into the house, thankfully preventing Yayoi from being exposed to the sun.

"How about we go tonight? I'll go with you." Sanemi lowered her head and spoke softly to Yayoi.

The team members in the courtyard were so shocked their eyes almost popped out.

Don't even mention that coaxing-child-like tone; I never even give them a kind look normally!

Is this some kind of double standard?!

Yayoi took a step forward, reached out and hugged Sanemi's waist, buried her face in his chest, and said unreasonably, "No, I want to go now."

He would be willing to brave any danger, even if it meant going out during the day, if his lover held him like that and made that request.

"Then let me think of a way." Sanemi ruffled Yayoi's hair, his mind racing. Should he hire a fully enclosed vehicle? From the base to Kyobashi Ward, he should be able to avoid the sun the entire way?

He was halfway through his plan when Yayoi interrupted him.

Yayoi broke free from Sanemi's embrace, raised her hand and pointed to the corner of the room, where a large, dusty wooden box was piled up.

"Isn't there one already?"

"Didn't you not want to be locked in a box?" Sanemi was taken aback.

"There won't be a second time anyway."

Yayoi pursed her lips, and as soon as she finished speaking, her body began to shrink.
