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

But generally speaking, shouldn't we all work together to defeat the boss?

Yuko opened her mouth, but hesitated to speak.

Seeing that Yuuko was staring blankly into space, Tamayo glanced at Nezuko and said softly, "With this child's strength, if she overcomes the sunlight, she will probably attract Muzan's attention even more than Yuuko."

With Yuuko's strength, she could naturally protect herself against Muzan, but they lacked the means to do so. If they were to use the Blue Spider Lily simply to overcome their own weaknesses, it would be far too dangerous.

Yuko's expression was somewhat moved, and she subconsciously looked at Nezuko.

Nezuko noticed Ikuko's gaze and couldn't help but tilt her head to look.

Indeed, as Tamayo said, neither Nezuko nor Tamayo Yushiro had the ability to escape from Muzan.

“In my opinion, Nezuko overcoming sunlight is actually a bad thing,” Tamayo added. “I already have a lead on a medicine to turn demons back into humans.”

Yuko's breath hitched, and she exclaimed in shock, "Turning a ghost back into a human? That's possible?"

Tamayo's purple eyes were filled with calm: "Yes, although it is still in the experimental stage, it just lacks a certain reference. As long as we can obtain the blood of the Upper Moon Demon Moon, I believe it is only a matter of time."

"Miss Shinobu is very intelligent and has provided many valuable suggestions."

Yuko even temporarily forgot about Nezuko, because that was a completely different matter from getting rid of Muzan's control.

If they had a way to turn demons back into humans, then Muzan would no longer be able to gain more allies.

Kokushibo...

No... his problem wasn't turning into a ghost... but that he hurt so many innocent people.

Tamayo continued the previous topic, saying, "If Nezuko overcomes the sunlight at this time, it will put us at a disadvantage if Muzan finds out."

Tamayo's words brought Ikuko back to her senses, and she once again fell into a daze.

Objectively speaking, Tamayo is right...

but……

Shouldn't they have used their bond with the demons to defeat Muzan together?

As an important character, Nezuko couldn't possibly be completely useless during the final battle against Muzan, could she?

Yuko couldn't refute Tamayo's words, nor could she convince herself.

She was reborn with memories of her past life, and even though she has forgotten most of them, her way of thinking from a higher dimension has not changed.

In her opinion, shouldn't a shonen manga like Demon Slayer, which leans towards plot-driven killing, be about the bond between comrades helping to defeat the Demon King?

"Then let's put the spider lily aside for now. Tamayo, see if you can make use of it." Ikuko rubbed her temples and compromised.

Tamayo nodded slightly: "Mm."

Yuko glanced at Nezuko again, pursing her lips slightly: "Then, I'll go back with Nezuko first."

"Yes, I'll let you know as soon as there's any progress."

Yuko got up to say goodbye, put Nezuko back in the box, and left.

Tamayo stared thoughtfully at the closed door.

This child... is indeed strange... seems to be hiding something... makes me a little uneasy.

……

Yuko led Nezuko toward the Butterfly Mansion.

There was another reason why she couldn't accept Tamayo's words...

If what Tamayo said is true, then her deliberate decision not to change the plot and put Nezuko in danger... is completely meaningless.

It's just hurting Nezuko.

Tanjiro is very kind. Even if Nezuko hadn't become a demon, I believe that after a serious conversation with him, and after learning about the great evil known as demons, he would have gladly accepted her request to help others.

Did she do something wrong?

"Ikuko?"

"Ikuko?"

"Ok?"

The gentle voice of the young girl in her ear brought Yuko back to her senses, and her vision quickly focused, revealing Shinobu Kocho's face.

She had already walked back to the Butterfly House without noticing at all.

Seeing that Yuko looked up and finally snapped out of her reverie, Shinobu Kocho couldn't help but laugh and say, "Why are you so engrossed? What are you thinking about?"

Yu Zi breathed a sigh of relief: "No...it's nothing."

Shinobu's brow furrowed almost imperceptibly, but quickly relaxed.

At this moment, Yuko changed the subject, saying, "I've already picked the spider lilies. If Shinobu wants to study them, she can go and take a look at Tamayo's place."

"Okay, I understand." Shinobu Kocho maintained her smile, then suddenly remembered, "Oh right, doesn't Ikuko no longer have a Nichirin Blade?"

"Should we ask the sword-forging village to reforge one?"

"A Nichirin Blade?" Yu Ziwei was taken aback. "Then please ask Shinobu for me."

She hadn't gone out during this period and had completely forgotten about it.

You still need a Nichirin Blade, otherwise you can't fight the demons. And she's different from other demons; she'll eat the ones who lose.

Without a Nichirin Blade, you can only slowly wear down the opponent's stamina, which is not very convenient.

"In fact, my lord asked me about this a few days ago." Butterfly chuckled. "Because the Demon Slayer Corps hasn't had a swordsman using Snow Breathing for a long time, and even the Swordsmith Village has lost its records."

"To forge a Nichirin Blade that is compatible with the Breathing Technique, I'm afraid I'll need Yuko to personally make a trip to the sword-forging village."

Shinobu Kocho held up one finger: "In other words, it's what you call custom-made."

Although her older sister Kanae could use Snow Breathing, the tradition of Snow Breathing had been somewhat interrupted at that time, and a few breathing techniques were not enough to fight. Therefore, the Nichirin Blade that Kanae forged was in harmony with Flower Breathing.

The village of forging swords had absolutely no experience in producing Snow Breathing swordsmen's swords.

"The sword-forging village?"

The village that produces Nichirin Blades was established during the Sengoku period and is another logistical organization for the Demon Slayer Corps.

Yuko had also been there to repair her Nichirin Blade, but so many years have passed that the location of the forging village in her memory may have changed.

After all, if it were the original site, it would probably have been demolished by Kokushibo and Muzan long ago.

After thinking for a moment, Yuko nodded: "I'm free at the moment, so I'll trouble Ren to make the arrangements for me."

Hearing Yuko say that, Butterfly clapped her hands with a smile and said, "Then let's not delay, rest for a day, and set off the day after tomorrow?"

"Since it was the Lord himself who inquired, the arrangements were made long ago."

“Okay.” Although she felt that Shinobu was being a bit too enthusiastic, Ikuko had no objections.

Although the thought of that pervert wearing the Fire Man mask gave Yuko a headache.

However, Yoriichi has already given his sword to Tanjiro, so he probably won't bother her anymore.

Thinking of this, Yu Zi couldn't help but breathe a sigh of relief.

Butterfly smiled and said, "I heard there's a magical hot spring in the sword-forging village that can cure physical fatigue. It'll be a good opportunity to relax."

"I'm exhausted these days."

Yu Ziwei was taken aback for a moment, then hesitated and asked, "Ren is going too?"
