Tsugikuni Yuko

Tsugikuni Yuko's previous name no longer matters, because in this life, she is Tsugikuni Yuko.

As the eldest daughter of the Tsugikuni family, she has two twin older brothers above her.

They are Eldest Brother Tsugikuni Michikatsu and Second Brother Tsugikuni Yoriichi.

That's right, she transmigrated.

She transmigrated into the world of Demon Slayer.

The immense popularity of Demon Slayer in her previous life meant that even Tsugikuni Yuko, who didn't actively follow the anime, couldn't avoid seeing related videos. Tsugikuni Yuko was drawn in by its exquisite special effects and art style.

However...

She must have transmigrated too early.

Yuko, who had watched one season of the anime, had only occasionally seen videos about Tsugikuni Yoriichi on short video platforms.

The most famous one, of course, was that line— "What do you consider life to be!"

But if she wasn't mistaken, Tsugikuni Yoriichi, the ceiling of Demon Slayer's power, her cheap second brother.

He should be a character from hundreds of years before the story began.

So, the question is, how can she possibly live until the story begins?

"Sigh." With a wooden flute hanging around her neck, Yuko rested her chin on her hands, sitting on the steps with a dejected expression. She watched her Eldest Brother, Tsugikuni Michikatsu, spar with their teacher below, her feet dangling unconsciously.

"Yuko, you can't sit like that. You need to sit properly."

Mother Akino's voice came from behind her. Yuko turned her head and saw Second Brother Tsugikuni Yoriichi leaning against Akino as he walked over, acting like a spoiled child.

"Mother." Yuko quickly shifted from her relaxed posture to the seiza she still hadn't gotten used to.

In her past life, her mother was a lazy gambler who squandered the family's assets and was indifferent to the family. She was the type of person Yuko found it difficult to respect or like.

As a result, she was completely unable to handle the overly gentle Akino.

After sitting up straight, Yuko let out a sigh of relief and reached out to greet her second brother, who was nestled beside their mother. "Yo, Yoriichi."

Who knew the legendary power ceiling was such a spoiled child when he was young.

As soon as she spoke, Akino rapped Yuko's head. "How many times have I told you, you must call him Elder Brother!"

"Yes, Elder Brother." Yuko rubbed her head in pain, failing to notice a fleeting look of pain flash across Akino's brow.

Mother Akino was a gentle person, but when she got angry, she was surprisingly formidable.

Facing his unreliable sister, Yoriichi simply smiled gently.

A gentle mother and brother, and a cute sister, were Yoriichi's most precious treasures.

Yoriichi helped Mother Akino sit down under the long corridor, with Yuko accompanying her.

He himself went to stand beside his Eldest Brother Michikatsu to observe.

The teacher instructing Michikatsu in swordsmanship was a subordinate of their father. Seeing Yoriichi standing quietly to the side, he handed him a wooden sword with a smile, inviting him to try.

Michikatsu, who was covered in sweat and sore all over from being hit by his father's subordinate, was allowed a short rest.

"Mother, Yuko." He walked to the corridor and looked up at his mother and sister.

"Elder Brother~" Yuko greeted him with a smile, then focused her gaze on the sparring match.

Michikatsu's brow twitched almost imperceptibly. He looked back, not believing his weak younger brother could last more than a few moves against the opponent.

After all, despite his talent and effort, he had never once defeated his father's subordinate.

However, to everyone's surprise, Yoriichi, who had only learned the posture for holding a sword from his father's subordinate, launched an attack with lightning speed, taking down the tall adult in the blink of an eye.

Michikatsu's eyes were filled with shock. Akino's small mouth was slightly agape in surprise. Only Yuko wore an expression of "just as expected."

As expected of the ceiling, possessing strength unimaginable to ordinary people at the age of seven.

Unlike the others' astonishment, Yoriichi looked blankly at the bamboo sword in his hand.

Hate, the feeling of hitting someone's body.

Yoriichi threw down the bamboo sword and returned to the corridor.

Michikatsu, still shocked, finally came to his senses. He sat down beside Yoriichi and quickly asked, "How did you do that?"

Yoriichi lowered his eyelids and calmly replied, "When he prepares to attack, his lungs will definitely move vigorously. You just need to clearly see the direction of the bones, the contraction of the muscles, and the flow of blood."

"..."

Yoriichi's words stunned Michikatsu. He couldn't understand what his younger brother was talking about at all.

Akino's eyes, however, flickered slightly.

This child Yoriichi, his eyes can see gods.

Yuko's eyes lit up even more. She knew this!

The highest realm for swordsmen, or rather, martial artists.

The Clear World!

The ability to see the enemy's weaknesses and attack intentions, as well as conceal one's own presence.

It's like seeing through things.

"Let's stop talking about swordsmanship. I'd rather play sugoroku and fly kites with Elder Brother and Yuko."

Yoriichi's previous wish was to become the second strongest samurai in the country, but the discomfort of hitting others' bodies made him completely abandon this wish.

Michikatsu lowered his head, his hands on his thighs clenched tightly.

Yuko playfully patted his shoulder and said with an air of maturity, "Don't be so tense all the time. Relax your body once in a while."

Michikatsu unceremoniously slapped her hand away. He didn't even say goodbye to his mother and left silently.

Yuko let out a sigh of relief.

She knew it.

Before her transmigration, Yuko wasn't entirely sure about the subsequent developments of the main story, but she had seen clips of Yoriichi's elder brother becoming the strongest demon under Demon King Muzan.

Upper Rank One [Kokushibo]

As for the "six eyes lemon spirit" that netizens talked about, she hadn't understood it back then, but at this moment, she seemed to grasp a little.

Very good, she was determined to correct this kid's twisted mindset!

Yuko felt she could do it. Come on, she was an adult university student in her previous life.

How difficult could it be to teach a child?

However, before she could complete the correction of Michikatsu's personality.

One night soon after.

"Yuko."

Yoriichi's voice startled Yuko awake. She opened her door, rubbing her eyes sleepily.

"What's wrong, Yoriichi?" Yuko yawned, looking at Yoriichi. "Are you scared to go to the toilet alone?"

Facing his unreliable sister, Yoriichi's expression was as calm as ever, but this time it seemed to be tinged with a bit of sadness.

"Mother has passed away."

"Huh?" Yuko jolted awake.

Akino...

Yuko opened her mouth, unable to speak.

"Inquire with Mother's attendants for the specific details," Yoriichi said quietly. "I am going to bid farewell to Elder Brother now."

"Farewell?"

"I am leaving for the temple."

Only then did Yuko notice the luggage Yoriichi had placed beside him.

Their father was a superstitious man. Yoriichi, who was born with ugly birthmarks, was not valued by his father. If not for Mother Akino's protection, Yoriichi would have died at his father's hands at birth.

In comparison, the treatment Yoriichi and Michikatsu received could be described as the difference between a master and a servant.

From food, clothing, housing, and transportation to education, the two were from different worlds.

And as the abandoned one, Yoriichi had to go to the temple when he turned ten.

To become a monk.

But... Yoriichi and Michikatsu were only seven years old now.

Yuko was even only six.

Yuko suddenly remembered the scene where Yoriichi defeated her father's subordinates earlier.

Her father needed an heir who could succeed him as the pillar of the family. Yoriichi's powerful talent had already caused a shift in their positions compared to Michikatsu.

Did Yoriichi choose to become a monk early to avoid affecting Michikatsu?

As Yuko stood there in a daze, Yoriichi said, "Yuko, I'm leaving."

"Take care of yourself."

With that, Yoriichi picked up his luggage and prepared to leave.

"Wait." Yuko blurted out subconsciously.

Yoriichi paused and looked at her.

When it was Yuko's turn to speak, her mind went blank, and she didn't know what to say.

Should she ask him to stay?

A seven-year-old child...

But Yoriichi could already defeat adults, far stronger than her.

In response to his silent sister, he offered a gentle smile.
