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

The crimson sunlight shone on Yuko's profile, making her wine-red hair seem to be tinged with a thin layer of luster.

Tanjiro's eyes narrowed slightly.

He seemed... seemed to have seen this scene somewhere before...

The scene before him seemed to change slightly in a daze. Something seemed to be hanging on Yuko's delicate earlobe, and even the houses behind her seemed to change slightly in Tanjiro's vision.

No, it seems that even Ms. Yuko's height is inexplicably a bit taller.

But when Tanjiro shook his head and looked again, there was nothing unusual about it.

Is it because you've been too tired lately?

My eyes are blurry.

Seeing that everyone had finally returned, Yu Zi breathed a sigh of relief; at least they hadn't forgotten about her.

Yu Zi said helplessly, "You guys are going too far."

Tanjiro scratched his head sheepishly: "Sorry, I was just thinking I could help chop more firewood."

After all, they're leaving tomorrow.

However, with so much firewood, it looks like we won't be able to move it back today.

Tanjiro and the others moved the pile of firewood that they couldn't move into the house to prevent it from getting wet in the rain.

Looking at the clean and tidy room, Tanjiro smiled slightly: "Miss Yuuko, thank you."

"Ok?"

Yuko turned around, and Tanjiro had already left.

What should I thank her for?

They carried the remaining firewood on their backs and headed down the mountain in a large group.

The contents of the house were left to the two brothers, Takeo and his brother, to carry down the mountain slowly.

Although Zenitsu was covered in dust and dirt today, he unusually didn't complain. Instead, he helped his brother carry a large bundle of firewood.

Inosuke, on the other hand, always seemed to have a lot of energy no matter what he did, and even after a long day of work, he was still full of energy.

I returned home down the mountain.

"Oh~ this is the blue spider lily?" Inosuke brought his face close to the flower with a wise expression, and you could see his breath touching the petals.

Yu Zi's eyelids twitched, and before everyone could get a good look, she took the flower back and carefully stored it away.

Everyone turned to look at Yu Zi.

Yuko remained silent, as if nothing had happened.

I'm sorry, it's not that she doesn't trust you, it's that you are completely untrustworthy.

During battles, she could safely entrust her back to them, but in ordinary times, these two were the most dangerous.

Especially Inosuke; Tanjiro was actually alright, he wasn't led astray by the two.

Don't make a scene and ruin all her flowers.

Considering how quickly the spider lilies wither, everyone left early the next morning.

Before leaving, while Kamado Hime was making breakfast, Tanjiro secretly hid the money under his mother's blanket.

The three people and one demon traveled at a rapid pace without any delay. Even Zenitsu, who had previously complained about the hot weather, silently kept up with the group.

Back with the Demon Slayer Corps, Ikuko took Nezuko and headed straight for Tamayo.

In the laboratory, Tamayo was observing something in front of the microscope when suddenly a cheerful, noisy voice entered her ears.

"Tamayo, Tamayo, look what I brought you."

"Idiot! Stop yelling like that!"

This was followed by Yushiro's dissatisfied complaints.

"Sorry sorry."

Yuko's voice rang out from the doorway, though she didn't sound remorseful.

With a creak, the door was pushed open.

Tamayo's gaze, which held a mixture of helplessness and doting affection, froze slightly when she saw what Ikuko was holding.

Her eyes widened in surprise, and she exclaimed, "This is..."

Yu Zi smiled slightly: "Blue spider lily."

"I came all the way here to bring this to you."

Yuko entered the room, placed Nezuko on the sofa, and handed the spider lily to Tamayo.

The flowers have already wilted a bit because of the hot weather.

Yushiro was shocked. That was the blue spider lily?

Tamayo's expression of surprise hadn't faded yet as she gently took the flower in her hand: "This is the Blue Spider Lily?"

"Something Muzan has always dreamed of."

Yu Zi smiled and said, "Hmm, see if you can use this spider lily to overcome the weakness of sunlight."

Tamayo paused for a moment, then asked, "Overcome sunlight?"

Yuko was also taken aback: "Is there a problem?"

Tamayo remained silent, staring blankly at Ikuko, lost in thought.

Yuko felt a little uneasy under her gaze.

After a long silence, Tamayo gently shook her head: "There's no need..."

"Eh?"

Tamayo looked at her with gentle eyes: "Yushirou and I didn't choose to stand with everyone just to overcome the sunlight."

“But this…” Yuko turned to look at Yushiro and found that he did not reject Tamayo’s words at all.

"Moreover, unlike Yushiro and Ikuko, we have no ability to protect ourselves when facing Muzan."

Upon hearing this, Yu Zi's words caught in her throat.

It seems to make sense.

Without much thought, she nodded: "Then let's talk about it after we defeat Muzan."

Tamayo's expression was somewhat complicated. When Ikuko looked up, she relaxed her brows and smiled gently.

"Although we can't use it, we can study it a little and see if we can make any new discoveries that can help us defeat Muzan."

"That would be very kind of you." Yuko nodded slightly. "By the way, could you check on Nezuko's health?"

"Are there any new changes in the cells?" She opened Nezuko's box and took her out.

Nezuko thought her older sister wanted to play with her, but before she could even reach out, she was pressed down into a chair.

Then blood was drawn.

Tamayo examined Nezuko under the microscope: "Hmm, it's hard to say, but there are indeed subtle changes compared to before."

"It might need a catalyst."

Yuko asked, "Can we use the spider lily?"

Tamayo cast a puzzled look at her, although she felt that Nezuko's body was changing, and that she might have accidentally eaten the blue spider lily before, so overcoming the sunlight might be possible.

But she vaguely felt that what Yuko wanted to express was somewhat different from what she understood.

She didn't know how to describe it, but she felt that Yuko was a little too concerned about overcoming the sun.

She asked, "Why is Yuuko so concerned about Nezuko overcoming the sunlight?"

Why do you care?

Yuko paused for a moment, of course, because Nezuko overcame the sunlight later in the story.

Overcoming the sunlight is definitely a key plot point.

"Because you think Nezuko can help everyone defeat Muzan, right?"

Ikuko gave an answer that left Tamayo completely baffled.

Tamayo tilted her head, a hint of confusion in her eyes: "Help?"

"Ah."

"What help?"

"What kind of help? Of course, it's..." Yuko suddenly paused.

What was the reason again?

What kind of bond bonuses are essential for protagonists in action-packed manga?

The story revolves around a human brother and a demon sister who team up to defeat the Demon King.

Isn't that right?
