Start with Demon Slayer and create the strongest demon sword!.

Demon Slayer Headquarters.

Butterfly House.

Tanjiro was on his way back, returning to the Butterfly House alone. The moment he stepped into the courtyard, he saw a petite figure waiting there.

That person was none other than the Insect Pillar, Shinobu Kocho.

When her deep eyes saw Tanjiro, she still had that unchanging smile on her face, and she just walked straight over and said with a smile.

"You just left for the lord, right? Did something happen?"

Facing the pretty face of Kocho Shinobu who was close to him, Tanjiro blushed slightly and replied, "Yes, I will leave the headquarters with Ajuramaru tomorrow."

Hearing this, Shinobu Kocho's smile froze.

But he quickly recovered and said with a wry smile, "Why are you in such a hurry to leave? Wouldn't you be lonely if you left your two friends behind?"

In response to Shinobu Kocho's question, Tanjiro didn't even hesitate, he just opened his mouth and blurted out the answer.

“No, it’s too dangerous for them to be with me, it would be best if they could stay.

And I also want to become stronger quickly, strong enough to protect everyone!"

This sincere expression also made Shinobu Kocho somewhat agree with it, but her expression remained unchanged and she was still smiling as always.

"Your heart is pure, no wonder you are recognized by Ajuramaru..."

After saying that, he turned his head and looked at the dark night in front of him and continued to talk to himself, "But, I still want to pin my dreams on you."

"dream?"

Tanjiro looked over with some confusion.

"That is for humans and demons to live in peace. I believe you will be able to do it in the future." When I heard Shinobu Kocho say this with a smile on her face.

Tanjiro beside him sniffed and clearly smelled the scent of anger, and immediately asked with some confusion.

"Are you angry?"

These words were like a sharp sword piercing her heart, directly breaking through the defense line in her heart. This time, Shinobu Kocho's smile finally disappeared.

Instead, there is a sense of loneliness.

"Angry? Maybe... maybe I've been angry ever since my sister was killed by a ghost... Whenever I see someone's life being taken away by a ghost, my anger grows.

I have an indelible hatred for evil spirits deep in my heart, and the other pillars probably feel similarly..."

In one breath, he released all the emotions that had been pent up in his heart for a long time.

After hearing this, Tanjiro could empathize with them, so now he is more determined in his beliefs!

"Ms. Shinobu, please rest assured that I will make everyone recognize Nezuko!"

"Yeah……"

Shinobu Kocho's smile returned to its former self.

And Ajuromaru in the sword, seeing this great opportunity, also reminded Tanjiro, "I'll borrow your body to tell you something."

Hearing this, Tanjiro answered without hesitation.

"Ok."

After that, he turned around and reminded Kocho Shinobu beside him, "Ms. Shinobu, Ajuramaru has something to tell you."

Upon hearing this, Shinobu Kocho, who was about to leave, sat back down and turned to look.

Tanjiro, who was originally gentle and warm, suddenly became cold and looked into those red eyes.

It will make people feel inexplicable palpitations.

But fortunately, she remained calm and asked with a smile, "Mr. Ajuramaru, what do you want to tell me?"

Even Tanjiro, whose body was taken away, was curious about what Ajuramaru would say.

And Ajuramaru didn't beat around the bush and went straight to the point, "You can find Ubuyashiki Yoya and ask him to look for a demon named Tamayo. Her knowledge of pharmacology is far superior to yours.

You two can work together to study Nezuko's blood. I can feel that Nezuko is different from those ghosts. She is very special!"

"Ghost?"

Shinobu Kocho felt a little resistant in her heart. After all, Nezuko was fine because she didn't eat humans, but who was this Tamayo?

There were many doubts in my mind, but since Ajuramaru said so, he must have his reasons, so I immediately replied seriously.

"Since that is your request, I understand. I will go and ask the lord in person tomorrow."

After receiving a positive answer, Ajuuramaru released his control over the body, but Tanjiro was not calm.

I couldn't help but ask in my heart.

"Ajuramaru, is there a chance my sister can turn back into a human?"

Faced with this urgent inquiry, Ajuramaru simply smiled and asked back calmly.

"Who knows?"

into the night.

The two went their separate ways, and Tanjiro returned to his room, where he lay in his bed and spent a peaceful night.

Until the next morning.

Ajuuramaru in the sword saw Zenitsu and Inosuke getting up and preparing to run away, so he had no choice but to release his ghost power.

He condensed a palm and gave a big dice to the sleeping Tanjiro.

Snapped!

A clear and pleasant voice rang out, and Tanjiro suddenly woke up from his dream, then looked around in confusion.

"What happened?"

The voice just fell.

I saw Zenitsu and the other man trying to run away, and Aguramaru's unhappy voice rang in my mind, "They two want to run, say goodbye before they leave."

"Thank you, Ajuramaru."

After Tanjiro thanked them skillfully, he immediately stopped Zenitsu and the other man who were a little embarrassed and spoke to them gently.

"I'm going to leave now to hunt down evil spirits. Please take care of yourselves, both of you."

"Eh?! Are you leaving now?" Zenitsu looked over in disbelief.

Inosuke, on the other hand, was panting heavily and yelling, "Let's go together and hunt down evil spirits together!"

"No, it's too dangerous to come with me..." Tanjiro rejected the suggestion firmly and said goodbye to the two of them.

Then he got up, packed his things, and walked out of the mansion alone, carrying two sharp blades on his waist and a wooden box on his back.

And outside the mansion.

Fushigi Miyabi was leaning against the wall, having been waiting here for a long time. When he saw Tanjiro, he took out a fox mask from behind and threw it over.

"From now on, you should wear this mask, and take off your Hanafuda earrings. It's getting late.

It’s time for us to set off.”

Having said that, he walked ahead without looking back.

Looking at his back, Tanjiro looked at the fox mask in his hand and put it into his arms, and took off the Hanafuda earrings on his ears at the same time.

"Thank you very much, Mr. Shiya."

The two of them set out on the journey together. A pitch-black crow was soaring in the sky, opening its beak and saying, "Northwest-northwest-northwest, someone is missing there..."
