Demon Slayer: Muzan, will you dance too?

Have you ever heard of the name Yoriichi Tsugikuni?

"The strongest swordsman, born with markings and a translucent aura, you were there when he met Muzan, weren't you?"

Upon hearing this, a look of obvious astonishment appeared on Tamayo's face, as if she hadn't expected that Kiyokawa Izumi really knew a lot.

"This is truly unexpected... Yoriichi Tsugikuni is the strongest swordsman I have ever seen, and he once pushed Muzan to the brink of defeat."

Unfortunately, in that instant, Muzan split his body into 1,800 pieces, and Yoriichi Tsugikuni was unable to stop him from doing so.

For a long time afterward, Muzan seemed to have vanished, never to be seen again.

Whenever this matter is brought up, Tamayo's emotions change noticeably.

"In order to develop a drug that can defeat Muzan, I need the blood of the Twelve Demon Moons for research."

Could you please help me collect them?

With a serious expression, Tamayo earnestly requested.

Neither she nor Yushiro were demons skilled in combat, so naturally they were unable to collect the blood of the Twelve Demon Moons for research.

"That's not a problem. I've collected the blood of Lower Six, Lower Five, Upper Six, and Upper Five, and they can be sent over later."

Kiyokawa Izumi was prepared, which is why he was able to agree so easily.

"!!"

Even the waning moon is an exception.

Even Tamayo was somewhat surprised to hear that the collected blood contained Upper Six and Upper Five.

I wasn't wrong, this young swordsman is really strong.

If demonization is just an illness, then it can be cured as long as a solution is found and corresponding medicine is made.

Tamayo, who has lived for hundreds of years burdened by hatred, has not given up on her revenge against Muzan.

She had a rough idea.

This plan is something she couldn't have accomplished on her own.

We need to gather enough powerful swordsmen, just enough to hold Muzan back, and kill him using sunlight.

The medicines produced should weaken Muzan as much as possible.

We cannot give it a chance to split up; the mistakes made hundreds of years ago must not be repeated.

The general framework of the plan is: use drugs to limit its effects, have a powerful enough swordsman buy time, and finally use sunlight to kill it.

As she said, her intervention in the battle between Kiyokawa Izumi and Akaza was not out of mercy, but simply out of hatred—Kiyokawa Izumi, with her formidable strength, might be the best candidate to hold off Muzan.

Having waited for hundreds of years, Tamayo was unwilling to wait any longer, which is why she took the risk of contacting Kiyokawa Izumi.

Upon learning that this guy had encountered three Upper Moons in succession, I was both shocked and felt that getting to know him was worthwhile.

Just then, Kiyokawa Izumi felt a distinct hunger pang in his stomach.

Upon hearing the sound, Tamayo was stunned for a moment before realizing that it was the sound of her stomach growling.

"Yushiro, could you please go buy some food?"

"Humans are such a hassle."

Yushiro was naturally extremely unwilling.

I don't want to be separated from Lady Tamayo at all!

Furthermore, he couldn't bear to leave Lady Tamayo alone with this guy.

"obedient!"

"I can't help it," Tamayo said helplessly.

Having already been asked to do so, Yushiro had no choice but to get up, not forgetting to glare fiercely at Kiyokawa Izumi before leaving.

Kiyokawa Izumi was also helpless.

It's normal to feel hungry after expending too much energy.

I feel like I could eat thirty bowls of ramen right now!

Tamayo's request was a trivial matter to him.

Akaza's blood was not collected at the time, and it is unknown whether any remains at the scene.

As for fighting Muzan or something, just thinking about it gives me a headache.

Even a weakened Muzan would be extremely difficult to fight – in his normal state, he might not even last three or five moves.

It's unlikely to be instantly killed; it should be able to struggle for a few breaths.

Even in his strongest theoretical state, he wouldn't stand a chance against Muzan.

Ordinary pillars, whether strong or weak.

Without mastering the three-piece set, even against a Muzan who has been infinitely weakened, the survival time is extremely short.

Mastering the markings only means you can hold out a little longer.

But what's the point of persisting for a longer period of time?

No amount of ineffective damage will hurt you much.

If Kiyokawa Izumi knew Tamayo's expectations of him, he would definitely have a question mark.

Do you think I am Yoriichi Tsugikuni?

Expecting me to stall for time? Are you kidding me?

I only wanted to fight Doma, but I didn't consider how to deal with Muzan.

"Ms. Tamayo, you must know about the markings, right?"

"Um?"

"Apart from Yoriichi Tsugikuni, most of those who awaken their markings do not live past the age of twenty-five. Could you please help me research this?"

If this problem can be solved, and the markings can be used without restraint, both I and the other pillars will see a significant improvement.

The person in front of him was, after all, the number one scientist in the Demon Slayer world. Suddenly remembering the side effects of the Demon Slayer Mark, Kiyokawa Izumi naturally wanted to ask him to study it.

"Stripes?"

Miss Tamayo pondered for a moment, "I have only ever seen one swordsman with the markings, Mr. Yoriichi Tsugikuni, who was born with the markings."

The side effects you mentioned did not occur in him.

If you could provide some blood from the Marked Swordsman, I could try to study it.
