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

Yuko just smiled and said, "These next few days, please let Aoi-nee, Tanjiro, and Nezuko have a good get-together."

Kamado Aoi looked at the two children without saying a word and nodded slightly.

Although she knew that Tanjiro and the others would still leave, hearing the answer from Yuuko still made her feel uneasy.

Tanjiro noticed his mother's sadness and comforted her, "It's alright, Mom. We fight so that people can live happy and joyful lives."

"So that no more tragedies will happen again."

Zenitsu, Inosuke, Nezuko... everyone in the Demon Slayer Corps is someone who has been harmed by demons.

To prevent the tragedy of demons from ever happening again, Tanjiro had long ago resolved to dedicate his life to it.

Seeing Tanjiro's determined expression, Kamado Aoi smiled gently: "You've grown up, Tanjiro."

That sensible child has become even more mature... he's now a pillar of strength.

"This..." Tanjiro blushed and scratched his head somewhat embarrassedly.

Yu Zi smiled and said, "Then I'll be troubling you for the next few days, Sister Kui Zhi."

"Okay, please feel free to stay here."

Yuko nodded slightly, then turned to Zenitsu and Inosuke: "The spider lilies haven't bloomed yet, so you're free to do whatever you want these next few days."

“This is Tanjiro’s territory. He knows it very well. You can have him show you around.”

Upon hearing this, Inosuke instantly revived, exclaiming excitedly, "Oh!! Tanjiro!"

"So this is your territory, huh!"

"You really are something else..."

Everyone: "..."

Did he even understand what people were saying?

Although Yuko suggested they wander around, the three of them had no intention of going out in such hot weather.

Of course, most importantly, Tanjiro felt an urgent need to become stronger whenever he thought about his helplessness when he was wandering around.

He pulled Inosuke and Zenitsu together and started training in the yard.

Zenitsu was initially unwilling; he had only come with Tanjiro to avoid training.

He went out to relax, so why does he have to exercise when he should be having fun? He might as well not go out at all.

But it didn't work.

Although Inosuke is silly and foolish, he doesn't want to lose to anyone when it comes to fighting. He may have felt the pain of defeat at that time, and because his desire to win was even stronger than Tanjiro's, his pain was even deeper.

So he accepted Tanjiro's suggestion to train hard without hesitation.

Two to one.

Zenitsu looked at Ikuko with a pitiful expression.

Yu Zi raised an eyebrow: "I don't need to exercise, but can you do the same as me?"

Zenitsu froze instantly, muttering something like "That's so mean" and "Even if it's true, don't say it like that," before joining the two of them with a sigh.

Hanako and Rokuta Kamado, the two children, had never seen anything like this before. They sat on the veranda with Nezuko, watching the three of them diligently exercising in the yard with great curiosity.

“They have a very good relationship,” Kamado Aoi said softly as she appeared beside Ikuko.

Yuko nodded slightly: "Yeah, don't let their unreliable appearance fool you, they are the kind of partners Tanjiro can entrust with his back in battle."

"Does she seem unreliable?" Kamado Aoi chuckled softly as she recalled the scene from earlier. "She is indeed a very... strange child."

Yuko smiled subtly: "No need to save face for them. Is Aoi-nee trying to say something like 'idiotic'?"

Kamado Aoi coughed lightly: "I didn't say that."

Yuko smiled and looked at Nezuko, who was being leaned against by her younger siblings, and said softly, "Nezuko, remember to retreat inside if the sunlight comes in."

Nezuko nodded, seemingly understanding, but not quite. She wasn't stupid; she would definitely stay far away from the sun when it came.

Seeing that Yuko was taking good care of the two children, Kamado Aoi's eyes softened even more: "Yuko, would you like some tea? I'll go prepare it."

Kamado Aoi was unaware that demons could not eat human food.

In the past, Yuko would have endured the discomfort and eaten some food, and now that her sense of taste has returned, it goes without saying that she would eat it.

What? There's food?

Yu Zi nodded slightly: "Then I'll have to trouble you."

She sat quietly on the other side of the corridor, watching the three of them exercise diligently.

Yuko's lack of exercise wasn't because she didn't want to become stronger, but because she had already reached the point where she couldn't become stronger anymore.

Whether human or ghost, strength has its limits.

If constantly training could break through limits, then humans would have already smashed mountains with a single punch.

Kokushibo's centuries of persistent training still failed to reach the level of Yoriichi or even Muzan, not because he didn't work hard enough, but because his limits were simply there.

The only thing Yuko can improve right now is the development of her sword form.

……

Time passed slowly, and the setting sun shone on Yuko, making her long, red hair even more crimson.

Nezuko had already hidden inside the house and was resting on Kamado Hime's lap.

The sounds of clashing weapons echoed from the courtyard, as the three engaged in a fierce melee.

They're not afraid of disturbing the peace.

Yuko sighed.

Suddenly, the door was kicked open.

"Mom! Flowers..."

Takeo and Shigeru, who look almost exactly like Tanjiro, froze in shock on their faces.

"Eh?" Tanjiro was stunned.

“Brother?!” Takeo’s eyes lit up.

Tanjiro sheathed his sword and smiled gently at the two of them: "Takeo, Shigeru, it's been a long time."

It looks like they were startled by the noise they heard outside.

She knew it.

……

After a friendly exchange with the Kamado family, the group settled down for the time being.

The sound of the three exercising often caused gossip among the neighbors in the town. Fortunately, Kamado Aoi had a good reputation in the town, and after explaining the situation, everyone understood.

Takeo and Shigeru, who had never touched a sword before, begged Tanjiro to allow them to touch the Nichirin Blade, and even awkwardly pulled the three of them aside, asking them to teach them swordsmanship.

Sure enough, no boy could resist something like this.

It gave the three little ones a real taste of being teachers.

As August arrived, a hot month, the group had unknowingly been resting here for almost half a month.

Yuko had long since figured out when the spider lilies would bloom, and before she could even overcome the sun, she would spend every year at Tanjiro's house.

Yu Zi estimated that it was time for the red spider lilies to bloom, so she called everyone to go up the mountain together.

"Here's a bento box. Be careful on your journey." Kamado Aoi stood at the door, smiling as she saw everyone off.

Along with Yuko and the others, the Takeo brothers also went up the mountain to chop firewood.

On the way, Takeo asked, "Brother, do you need my and Shigeru's help to find what you're looking for?"

"No need. In fact, we should be the ones helping to chop the wood."

Yu Zi chimed in, "You guys go ahead, I'll take care of the picking."
