Demon Slayer: The Journey of Becoming Yoichi's Sister

"I'm back." Yuko tilted her head slightly, a little embarrassed.

Yuichi stood behind the door and smiled, "I'm glad you're back."

"Come in."

He moved aside half of his body.

"Yeah." Yuko replied lightly and walked into the house with her head down.

Yuichi noticed her absent-mindedness and asked, "What's wrong? Did you encounter any trouble outside?"

Compared to when he was young, the old Yuichi had more of the life of a mortal.

"No... I just haven't been home for too long, I'm a little uncomfortable." Yuko made an excuse casually.

Yuichi smiled and said, "Do you still feel uncomfortable?"

Yuko pursed her lips and looked up at Yuichi.

There were many white strands in her fiery red long hair, and wrinkles began to appear at the corners of her eyes.

Yuichi is really old.

Yuko felt a little blocked in her heart. She didn't communicate too much with her brother, so she fell asleep in a depressed mood.

The next morning, when Yunyi came to Yuko's room, he found that she was gone.

This should be the worst decision Yuko has ever made.

Perhaps this time she left, she would never see Yunyi again.

In ancient times, people who were fifty years old were considered old, and every extra year of life was a surprise.

But she did not stay with Yunyi to take care of him, but ran away.

...

Many years passed in a flash.

Yuko wandered around this land in a daze.

When she returned to her hometown again, she actually walked here unconsciously.

How many years have passed?

Ten years? Or twenty years?

The influence of longevity made Yuko almost unable to judge time too accurately.

Many years have brought many changes to the city. When Yuko came to the familiar door uneasily.

Her five fingers hovered in front of the door and hesitated to knock.

Yunyi... is he still alive?

Yuko began to regret whether she should have run away last time.

Maybe the owner of this place has changed.

The moment Yuko retracted her arm, the door was opened from the inside.

She did not feel the breath of someone approaching.

Yuko was surprised for a moment and subconsciously looked up.

She saw an old man with white hair and a frail appearance.

The old wrinkles covered the old man's cheeks, making him look old and ugly.

When she saw the familiar marks on the old man's cheeks, tears overflowed from the corners of Yuko's eyes.

Yunyi smiled gently, and the wrinkles on his face were moved. This smile was not very good-looking.

"Welcome back."

Yuko's lips kept trembling, and finally turned into a sound.

"I'm sorry..."

She shouldn't have left.

...

Inside the house, Yuko lowered her head deeply, not daring to face Yunyi.

Opposite her, Yunichi said softly: "Yuko, you did nothing wrong."

"But I haven't been back for these years."

Yuichi said gently: "I understand your pain."

Yuko subconsciously looked up with tears in her eyes.

Realizing her movements, she quickly lowered her head again.

Yunichi suddenly took out envelopes from his arms and handed them to her.

"What is this?" Yuko took it in confusion.

Yunichi smiled and said: "It's Tanji's letter."

Under Yuko's encouragement, Yunichi and Tanji have kept in touch since then.

Yuko opened the first letter, which contained greetings from Tanji's family to the brothers and sisters.

At the same time, they were also concerned about her situation.

She left without saying goodbye that day, which made the thoughtful Tanji notice it.

Tanji comforted her in the letter.

Most of the remaining envelopes were also greetings to them, and they were also looking forward to their visit again.

Judging from the yellowing of the envelope, it was already written many years ago.

Yuko was touched, but also felt guilty.

Yunichi said softly: "Birth, aging, illness and death are the norm in the world. We should all face them calmly, right?"

"But I..."

"Isn't there something I haven't finished yet?"

I was slightly stunned. Defeat Muzan?

Iko nodded heavily.

Yunichi smiled and made a rare joke: "Rest early. I will test your swordsmanship tomorrow morning."

"Good night."

"Good night." Yuko murmured.

Is she going to send her brother away this time when she comes back?

There is little vitality left in Yunichi's body, and he has almost reached the end of his life.

I'm afraid he won't live long.

She really came back at the right time.

Yuko thought self-deprecatingly.

After she fell asleep, Yunichi in another room inexplicably felt a strange feeling in his heart.

Is it uneasiness?

Or something else?

This strange feeling drove him to leave home and town late at night.

He went to the suburbs alone.

It was also when he arrived in the suburbs thatAt that time, Yunyi finally understood what the strange throbbing in his heart was.

It was the blood relationship between the twins.

"This is impossible... Why are you still alive?"

"Swordsmen with spots on their bodies are destined to live no more than 25 years old."

"Why are you the only one... who can live until now..."

What Kokushibo couldn't understand was that after a lapse of sixty years, the younger brother who should have died long ago appeared in front of him like a nightmare.

Tears flowed from Yunyi's heart: "How sad, brother..."

He was actually pitied by this creature who was once his brother but was now old and weak?

Kokushibo's heart, which had gradually become cold due to demonization, was once again stirred up.

But... he didn't feel angry at all.

Instead, he was strangely shaken by the other party's call of brother.

It was an emotion called sadness.

These were the few emotional words he heard from his emotionally indifferent younger brother.

But as long as the other party is still a demon hunter, he must cut off the offender, even if it is his brother when he was a human.

Even if he is in such a fragile posture now.

Just when Kokushibo wanted to draw his sword, Yoriichi drew the Nichirin Sword from his waist before him.

The atmosphere at the scene suddenly became tense, and Yoriichi's momentum almost materialized and pressed on Kokushibo's shoulders, like a boulder.

This old and weak creature had no flaws in his posture.

"I'm coming."

As if announcing death, Yoriichi's extremely fast speed accompanied the old voice.

So fast that Kokushibo had almost no time to react.

The next moment.

The strongest demon after the demon king Muzan, the upper string one.

A trace of blood gushed out from Kokushibo's neck.

Why...

Why is it that only you are always special...

Even though he is a spotted swordsman, and even though he is skinny, his slashing power and speed are almost the same as in his prime.

Those memories that Kokushibo had long forgotten reappeared in his mind.

Kokushibo's jealousy, which had been calm for decades, burned again.

I hate you, I want to kill you!

Kokushibo turned around angrily, his hideous face like a devil.

But at the same time, Kokushibo also understood that he would not have a chance to dodge the next move.

The next blow from Yoriichi would definitely take off his head.

The strong impatience and frustration seemed to crush Kokushibo's internal organs into meat paste.

However...

Yuriichi was unable to swing the next blow, and he just stood there, and passed away after his life span was exhausted.
