Demon Slayer: The Journey of Becoming Yoichi's Sister

Yuko also thought that she was the protagonist.

After all, it is generally acknowledged that the time traveler is the protagonist, right?

But when she was injured by the evil spirit and her lungs were severely damaged, and she could only curl up in bed in pain and sweat and couldn't sleep many nights, and when she couldn't beat Yuichiro no matter what, she understood.

Even if she was the protagonist, she was the protagonist of a sad drama.

She was not the protagonist.

Yuko understood this fact very well.

The sense of superiority of the time traveler over the known plot has long disappeared.

Therefore, she was extremely eager for this era, and had great expectations for this ray of light that would inevitably appear in the future.

I will complete the long-cherished wish that my brother failed to fulfill?

She herself had no idea how confident she was in this sentence.

So when Tanjiro really appeared in her eyes, Yuko felt from the bottom of her heart that the burden on her shoulders was much lighter.

When a scratch appeared on her cheek, Yuko unconsciously noticed that she was crying.

Were they crying with joy?

Perhaps.

The figure dancing in the snow like a fire spirit really made Yuko see some of Yoriichi in it.

She watched all the sword forms of Sun Breathing silently until the Kagura dance was over. It was almost dawn.

After Tanjuro finished the Kagura dance, he picked up Tanjiro who ran out of the house. His wife Aoi Kamado held the still young Nezuko and stood in the corridor with a smile.

It looked like a happy family.

Yuko suddenly fell silent.

She had forgotten how many brothers and sisters Tanjiro had, but there must be quite a few, at least four or five.

…

Then she…

should she remain indifferent?

Rationally speaking, she needs to pin her hope of defeating Muzan on Tanjiro. In this era, only Tanjiro can use Sun Breathing, and she is just a half-baked one.

Those who exhaust their ways will end up in the same place.

Swordsmen who use different breathing methods will eventually reach the same pinnacle as long as they can practice to the extreme.

However, Sun Breathing is superior to other breathing methods, which is a fact that cannot be changed in any way.

Even if it is the Moon Breathing that has been improved by Kokushibo and has an unstoppable range, it has only enhanced its power. The special attack against evil spirits belonging to Sun Breathing cannot be replaced by other breathing methods.

Not to mention Nezuko.

If she really changes the plot, it may cause Nezuko to not become a demon.

The ending of this kind of youth comic, Yuko knows it with her brain, it must be that Tanjiro and his sister cooperate with humans and demons to defeat Muzan together.

But from a personal perspective, she is uneasy.

Yuko took two deep breaths.

It's not the time yet. Tanjiro is still a little kid. There are at least several years before the plot begins. She still has several years to think about it.

It's not a big problem.

...

Thinking like this, Yuko turned and left the forest and walked down the mountain.

She took two steps out, her feet sank into the snow, and she stopped moving.

Yuko tightened her grip on the Sun Blade.

No... No...

Did she really think it wasn't time yet?

Or was she going to use another excuse when the time came?

Was she saying that she was entangled with other things, or that the time was a little later than she expected.

Just say that she didn't make it in time. Anyway, she hadn't played any role in all these years, and her investigation into the Upper Ranks only found out information about Douma.

In these years, had she seen enough people die?

Could the death of these people really affect her conscience?

She was still running away.

What was she afraid of?

Yuko looked back and saw a happy family walking towards the house.

If nothing could be changed, then what was the meaning of her coming to this world?

Then why did she go to such great lengths to overcome the sunlight with the blue red spider lily?

Was it so that she could live forever?

That was ridiculous.

Yuko leaned against a tree with her eyes tightly closed.

She wanted to change something.

She had survived until now just to change something.

At a certain moment, Yuko suddenly opened her eyes, and then walked down the mountain unwaveringly.

She would come back again.

…

Somewhere in the mountains, a stunning orange-red arc shone, illuminating the woods at night.

"Breathing of the Sun·Twelve Forms·Flame Dance!"

The arc never disappeared, and another brighter flame rose.

Yuko panted slightly, connecting all twelve moves. With her qualifications, it was already the limit to cut through the twelve forms within three seconds, and even if she turned into a demon, it would only take two seconds at most.

Yunyi could connect all the moves in an instant, and the difference between them was no exaggeration.

And…

That isEven with her demonized body, this body adapted to sunlight, she couldn't fully exert the Sun Breathing.

The load on the body completely exceeded its function.

For her, pure Sun Breathing was a side effect.

Yuko originally wanted to try to scare Muzan with her face.

With Muzan's more stable temperament than Sima Yi, he might really be scared by her, but if he is not scared, then she will be the one to be broken.

Sure enough, the best way is to let Tanjiro's family move temporarily. As long as they are all outside at that time, Muzan will naturally lose his target.

Yuko let out a long breath, packed up her things and went down the mountain.

...

A fierce battle is breaking out on the edge of the town at the foot of the mountain.

Yuko felt the movement from a distance, and the air was filled with a little blood and the stench of evil spirits.

And... the level is not low.

Is it the Twelve Demon Moons?

The aura was strangely familiar, as if she had met him somewhere before.

Yuko couldn't help but move her feet. When she arrived at the scene, she realized why she felt so familiar.

Red shirt, a strange red cloth on his head.

Douma!

At this moment, his aura was much stronger than when Yuko first met him a hundred years ago. I'm afraid his position was not just as simple as Upper Six.

And the person fighting with him was...

Yuko's eyes narrowed slightly.

A red and green butterfly haori fluttered in the wind, and the figures in the battle danced like butterflies.

Butterfly... Shinobu?

Why could he face Douma at this point in time?

Did her existence incite the butterfly effect?

She didn't remember much about the information about the Taisho Nine Pillars, because many people only showed up at the time, and Yuko only remembered a few of the most distinctive features over the years.

For example, the Flame Pillar, who spoke loudly, she still remembered that look, because their clan looked the same, and she occasionally met him over the past few hundred years.

For example, Shinobu Kocho, who is petite and uses poison...

Yuko was suddenly startled, wait...

This height and body shape...

It feels a little wrong.
