Demon Slayer: Starting from the Tsugikuni Family Chapter 71 68: Yes, She Did It On Purpose

So might wonder, if that's the case, couldn't Mitsuba just find a ti to examine all the causal threads on every geisha in this pleasure house at once?

Why go through all this trouble, wasting ti every night coming here with her brother's face pretending to be a custor?

Eh~ you just don't understand~

As the saying goes, in work, there must be balance between labor and rest, pushed forward bit by bit.

For a "worker," the most important thing to avoid is finishing all the work at once.

That way, when you later have nothing to do and your "boss" sees it, he won't think you're very capable—instead, he'll think—

"Oh, you seem quite free, co here and help handle this too!"

In the end, your salary doesn't increase, but your workload actually grows.

So, rather than solving everything at once, Mitsuba feels it's better to push forward little by little.

After all, she has plenty of ti, and Lord Muzan isn't rushing her to resolve this matter imdiately...

Life as an oni is all about enjoying the process~

So might also be curious, why does she have to use her brother's face of all things—wasn't that deliberate?

To this, Mitsuba must seriously state—

Yes, she did it on purpose.

She just wanted to see her brother's serious, rigid face appearing in the entertainnt district while frolicking with geishas.

Not only that, later she'll also find a way to drag her brother—who has nearly devolved into a caveman—personally to the entertainnt district.

Then find ten talented and beautiful geishas to surround him at once, properly changing his habit of always having a sour face, letting him have so fun too.

Hehe~

"Lord Yori-tsu~ what song would you like to hear tonight~"

"Whatever, you decide."

"Ugh~ Lord Yori-tsu always says that~ don't tell you hate us sisters~"

"Nonsense, how could I hate such beautiful girls."

"Lord Yori-tsu~ here~ let feed you fruit~"

"That won't be necessary, I don't eat such things at night."

Inside the room, with Yori-tsu's face, one hand supporting her head, Mitsuba relaxed half-lying on the bed.

While skillfully responding to the geishas around her who were so enthusiastic they wanted to pounce and kiss her, she repeatedly swept her gaze across them.

[Hmm, seems like tonight's batch of geishas doesn't have her either...]

Like the previous days, among tonight's geishas, Mitsuba also didn't see any causal threads intersecting with that mysterious wealthy rchant.

[Seems like tonight I can enjoy myself leisurely too... hmm?]

Just as Mitsuba sat up, preparing to join the geishas' musical performance and have so fun.

Her peripheral vision accidentally noticed a geisha sitting alone in the corner of the room, from beginning to end bowing her head in silence, quietly following her companion playing the biwa.

This was a sowhat special geisha.

Her kimono wasn't as bright and magnificent as the other geishas, even sowhat worn, her long bangs hanging down covering her face, making it impossible to see her features clearly.

Since entering the room until now, this geisha seed to always sit in that corner, neither speaking with others nor showing any intention of pleasing Mitsuba.

With her extraordinary mory, Mitsuba recalled this geisha's na.

Her na was Akari. Earlier downstairs, the madam seed to have ordered her to bring Mitsuba and the other geishas to this room.

Of course, what truly caught Mitsuba's attention wasn't the strange behavior shown by this geisha Akari.

But rather the causal thread coiling around her body, a thread so thin it was almost invisible.

Seven days ago, she had served the mysterious wealthy rchant Mitsuba was looking for.

Seven days...

This matched exactly with the ti Mitsuba had traced earlier, when this mysterious wealthy rchant intersected with the caravan leader.

Good, she finally found her.

"..."

"Miss Tamayo, are you certain we really must do this?"

Midnight, at a residence where the leader of the Demon Slayer Corps was hiding, with no outsiders present.

Ubuyashiki, whose face had begun showing traces of the curse, looked at the girl with dark purple pupils before him, asking doubtfully.

The girl was undoubtedly Tamayo, who had disappeared for nearly a hundred years.

Since parting with Yoriichi more than eighty years ago, Tamayo had been continuously striving, attempting to complete on her own the dicine she envisioned, which could turn demons back into humans.

However, not long after beginning her research, Tamayo realized that to develop this dicine, demon blood was essential.

Without available research samples, nothing could begin.

But the key problem was, with Tamayo's own combat strength, she could at most obtain blood from extrely weak demons.

For truly powerful demons, even if she encountered them, it would only result in a aningless death.

And the Muzan cells in these weak demons' blood were extrely scarce, completely insufficient as her research samples...

The research had reached a dead end here.

After several hesitations, Tamayo finally decided to seek help from the Demon Slayer Corps.

She still needed to rely on the Demon Slayer Corps' power to obtain blood from those powerful demons.

Of course, when asking for help, one certainly couldn't co empty-handed.

So, over the past several decades, Tamayo temporarily set aside her research on the "human-reversion dicine," instead diligently developing "poison" that could effectively damage powerful Upper Rank demons.

Turning demons back into humans was difficult, but if one simply considered how to kill demon cells, the difficulty was much simpler.

After all, there did exist a plant that could naturally suppress demons—wisteria flowers.

Wisteria flowers to demons were like arsenic to humans, both were deadly poisons.

Even powerful demons were no exception; it was rely a matter of quantity.

As long as enough was accumulated, even the mightiest demon could be poisoned to death.

The only difficulty Tamayo faced was how to make demons unaware of the wisteria poison's presence in their bodies before the poison took effect.

To overco this, she spent decades, finally successfully developing an inhibitor that could temporarily suppress wisteria poison.

This substance was non-toxic and harmless, able to suppress wisteria poison for a certain period, thereby temporarily preventing the demon cells in the body from showing rejection reactions to wisteria.

When the inhibitor completely lost effect and the wisteria poison began to explode in concentration, these toxins had already successfully spread throughout the demon's body.

In this way, even if it couldn't instantly kill those powerful demons, it could greatly weaken their strength in a short ti, creating favorable opportunities for demon slayers to behead them.
