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

Tanjiro couldn't help but ask, "Is it possible for Nezuko to overcome sunlight as well?"

He had actually wanted to ask this question all along, but since Yuko hadn't said anything, he had to keep it to himself.

"of course."

That's how it's written in the plot.

Yu Zi wrote it down in her little notebook.

But Yuko wasn't sure if she could overcome the sunlight now.

Logically speaking, Nezuko should have taken the Blue Spider Lily. Perhaps, like her, she overcame it by putting it in the sun for a while.

But ever since she learned that her ability to break free from Muzan's control was likely related to her own constitution, Yuko has become somewhat uncertain.

The main issue is that Nezuko is currently in a deep sleep, and her body seems to be evolving.

Perhaps the ability to overcome sunlight is not something we have innate, but rather something we acquired through evolution.

Muzan increased the number of demons partly in order to find demons that could overcome sunlight.

The vast majority of humans who died directly at Muzan's hands were actually unable to withstand his blood.

Not everyone is qualified to become a ghost.

"That's great." Tanjiro breathed a sigh of relief.

He originally had only one idea: to turn Nezuko back into a human.

But now, if we can overcome the sun first, that would be good too, at least we can be like ordinary people.

……

After a moment of silence, Tanjiro slapped himself in the face.

Why didn't he just ask Miss Yuko how to turn the ghost back into a human?

So stupid.

After muttering a thought to himself, Tanjiro asked Ikuko about it.

Yuko shook her head.

Tanjiro looked slightly disappointed. That's right, if it were possible to turn back into a human, Miss Yuko would definitely have already turned back.

There are currently no examples of ghosts turning back into humans.

Tanjiro's eyes dimmed slightly.

Yuko continued, "But Nezuko is special. Unlike other demons, she has never eaten human flesh and even replenishes her strength by sleeping."

Tanjiro was slightly taken aback. "Miss Yuko... have you ever eaten human flesh?"

He didn't want to think about it.

"Her body is changing, that's for sure, and perhaps in the future, she will be able to turn back into a human."

"Really?" Tanjiro perked up instantly.

"Really." But we'll have to wait until the finale, right?

Ikuko didn't say the second half of her sentence, which only annoyed Tanjiro.

Tanjiro was excited for quite a while after receiving this news.

The two descended the mountain together. Upon parting, Master Urokodaki gave Tanjiro a mask to ward off misfortune and protect him from harm.

Compared to a few months ago when he was pessimistic about Tanjiro, Sakonji now has a lot of confidence in him.

Perhaps it's because the knot in my heart has been untied.

After waving goodbye to Tanjiro, Ikuko stayed at Mount Sagiri for the time being.

Even if she were to be selected in the final round, it would be impossible for her to help Tanjiro with his assessment. Besides, given Tanjiro's current strength, there wouldn't be any problems.

Urokodaki Sakonji has gradually come to understand Ikuko's thoughts. He had previously wondered why Ikuko stayed by Tanjiro's side every step of the way.

Think about it now.

It seems that Ikuko sees Tanjiro as her hope for defeating Muzan.

The origin of breathing techniques.

The breath of the sun...

I never expected that child would have such talent.

Even after learning Yuko's true identity, Yuko and the old man still got along harmoniously.

Although Sakonji Urokodaki felt that Tanjiro was too sympathetic towards demons, he himself was also a gentle person.

The fact that they can tolerate Nezuko's existence is enough to prove it.

During their conversation, the two suddenly turned around and looked into the room.

Nezuko had somehow appeared at the doorway, staring at them with a curious expression.

She tilted her head and looked at Yuko, the blank look in her eyes gradually brightening, and happily ran towards Yuko.

Yuko caught her and smiled, "Nezuko, you still remember me."

Nezuko happily rubbed against her.

She held Yuko in her arms, her gaze suddenly falling on Urokodaki Sakonji beside her.

After a pause, Nezuko released Ikuko and lunged at Urokodaki Sakonji again.

Master Linlong quickly caught her, feeling as if he had raised his daughter in vain.

If only all ghosts were such adorable creatures.

Yuko smiled and said, "Tanjiro will be very happy to be back."

"Hmm." Urokodaki Sakonji stroked Nezuko's head, looking very pleased.

After rolling around with Master Urokodaki, Nezuko jumped into Ikuko's arms.

It's warmer and softer here.

Seeing Nezuko acting like such a well-behaved child, Yuuko couldn't quite understand it.

Logically speaking, ghosts can talk and have decent thinking abilities, with intelligence similar to that of ordinary people.

But Nezuko... not only can't speak, but her intelligence also seems to have decreased considerably.

Is it a side effect of evolution?

Her wine-red eyes showed a hint of confusion, and Yuko couldn't help but tilt her head.

Nezuko tilted her head as well.

Roughly... the intellectual level of a kindergarten student.

Yuko felt ashamed.

……

Many days later, in the evening, Tanjiro returned, leaning on a stick and looking disheveled.

When I saw Nezuko standing outside the door, all the hardships of the past few days didn't matter anymore.

"Nezuko, you're awake!"

Nezuko turned around upon hearing Tanjiro's voice and ran towards him.

The brother and sister hugged each other.

"You're back alive, Tanjiro." Urokodaki Sakonji was also moved and stepped forward to hug the two of them.

Nezuko peeked out from her arms and winked at Yuuko, as if to say, "Come here quickly."

Yu Zi chuckled and shook her head.

She wasn't used to such emotional scenes.

Tanjiro passed the final selection, but because he still had to wait for the Nichirin Blade to be forged, he stayed in Mount Sagiri for another half month.

One day, about two weeks later, a man wearing a straw hat with a wind chime on it and a fire man mask appeared on Mount Sagiri, carrying a long box on his back.

"My name is Steel Mound, the one who forged the sword for Tanjiro Kamado."

"I am Tanjiro Kamado, please come in and have a seat!"

Inside the house, Yuko was playing a preschool game with Nezuko, where they would clap once and I would clap once.

The arrival of the Steel Tomb immediately attracted everyone's attention.

"The material of the Nichirin Blade is..." Haganezuka first introduced it to himself, then handed the Nichirin Blade from the long box to Tanjiro.

"The Nichirin Blade is also known as the Color-Changing Blade, as it changes color depending on its owner."

Tanjiro solemnly drew his sword, and a black slash instantly extended to the tip.

It's the same color as Yoriichi.

Yuko glanced sideways.

"black."

"Black..."

Tanjiro sensed something was amiss from the subtle tone in the words spoken by Hidetoshi and Urokodaki.

"Huh? Doesn't black feel good? Is it an ominous sign?" Tanjiro said in a panic. "But I remember that Miss Yuuko's sword is also black, right?"

"No, my knife is actually..."

Before she could finish speaking, Hidetoshika, who had been looking at her because of Tanjiro's words, naturally reached out his hand after seeing the Nichirin Blade at her waist: "Could you please let me take a look?"

Yuko: "...That's possible."
