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

what the hell.

So that's what you were worried about?

He's still just a kid.

Shinobu Kocho asked with a smile, "Most of the Pillars of the Demon Slayer Corps, except for me, are on missions all year round. Tanjiro should know this, right?"

"Hmm." Tanjiro nodded, puzzled.

Actually, it wasn't just Zhu; the other team members were the same.

As long as they are not injured to the point of being unable to move, they will continue to go out on missions.

Because the number of swordsmen in the Demon Slayer Corps is far too small compared to the number of demons.

The pillars had almost no time to rest, otherwise there wouldn't be any stepsons.

"Doesn't Tanjiro find that strange?"

"strangeness?"

Shinobu Kocho raised her index finger and shook it: "Why are my missions still easier than before?"

easy?

You call it easy to encounter several of the Twelve Demon Moons in a row, especially the Upper Moon Three's mission?

Tanjiro suppressed the urge to retort and silently nodded.

Although she was unlucky and kept running into powerful enemies, she was generally not in great danger, and Ms. Yuuko dealt with Upper Moon Three all by herself.

"Actually, it's because Tanjiro, you are the inheritor of the original breathing technique, and Ikuko, the only one in the Demon Slayer Corps who can teach you, is deeply trusted by the Master. That's why we gave you orders within the scope of Ikuko's permission."

"I didn't tell you how to activate the markings because Miss Yuko didn't ask, so my lord didn't say anything more."

"Our lord actually cares about you far more than you think."

Tanjiro suddenly realized, "So that's how it is!"

"Well, if you want to ask how to activate the markings, go ask Yuko."

"I understand."

……

What are stripes?

"Miss Yuko! Please tell me how to activate the markings!"

"Forget it, Tanjiro, Inosuke, that sounds really bad."

In the corridor of the Butterfly Mansion, the three little ones surrounded Yuko.

“Spots?” Yuko blinked and pointed to her cheek. “It’s these.”

"...Isn't this a tattoo?"

"No, this is proof that the body has reached its limit, a special technique to strengthen the body."

Everyone's eyes widened: "Body enhancement?!"

"Yes, activating the markings will make your body stronger."

Inosuke looked up, two tall white puffs of steam shooting out of his pig-like nostrils: "I want this!"

Yuko looked up at everyone and said, "However, there is one drawback: swordsmen who activate their markings usually do not live past the age of twenty-five."

"..."

Zenitsu Agatsuma tried to push the two away, saying, "Forget it! Let's go!"

Tanjiro said seriously, "Please tell me how to activate the Demon Slayer Mark!"

Inosuke flexed his biceps: "I'm not going to fall behind! I'm activating my mark right now!"

Zenitsu was in despair.

Yu Zi broke out in a cold sweat, wondering if this guy had even understood what she was saying.

For the vast majority of the Demon Slayer Corps, becoming stronger by shortening their lifespan is undoubtedly a good thing.

However, not everyone is aware of this, so when it comes to markings, Yuko usually explains the pros and cons.

Tanjiro was somewhat lost in thought. The markings... he had always thought that Yuuko's face had tattoos.

So, is the one on Dad's forehead also one?

Tanjiro couldn't help but ask, "Miss Ikuko, are some of these markings... congenital?"

“Yes…” Yuko was somewhat surprised by his question, “Moreover, those born with markings will not be affected by a shortened lifespan.”

If Muzan had been bolder back then, perhaps Yoriichi could have ended the existence of demons in that era.

“My dad has a natural scar on his forehead.” Tanjiro changed his words at this point, “Ah, but it could also be a birthmark.”

"Is Yuko's the same?"

"No, my markings awakened later."

Tanjiro's father?

Yuko recalled that sickly young man; indeed, the young man's breathing technique was quite skillful.

but……

The patient's constitution is too weak...

Even those born with birthmarks don't live long.

If they were still alive, they could indeed become a powerful fighting force.

Speaking of physical constitution.

Tanjiro, the strongest of the three, is still not strong enough in his current physique.

While the awakening of markings is not absolutely related to physical constitution, the stronger the physical constitution, the easier it is to awaken, and the stronger the markings become after awakening.

This is beyond doubt.

They are still some distance from the pillar.

After a moment of contemplation, Yuko said, "Let's put the awakening of the markings aside for now... let's focus on building a solid foundation."

"Your bodies aren't strong enough. Even if you activate your markings, you won't become much stronger."

Their physiques are undoubtedly much stronger than Shinobu Kocho's, but judging the strength of a person's physique is not so simple.

While Shinobu may not be as strong or physically powerful as the others, her speed of charge is among the best in the Demon Slayer Corps.

Her body had almost reached its limit.

Tanjiro and the other two haven't yet; they still have a lot of room to grow.

Upon hearing this reply, the three children reacted with different expressions.

Tanjiro was somewhat disappointed.

Zenitsu was so moved he almost cried.

"Yoshi!" Inosuke suddenly went berserk, raising his arm high and grabbing one person with one hand.

Zenitsu: "Idiot, what are you doing?!"

"Exercise! Exercise!"

Inosuke led the two away in a frantic run, leaving Ikuko looking completely bewildered.

She still couldn't understand this pig's thought process.

……

After watching the three leave, Yuko sat on the veranda in a daze.

Not long after, light footsteps came from behind.

Yuko turned around and saw Butterfly Sister.

Kanao Butterfly subconsciously stopped and stood a short distance away, somewhat reserved.

Yuko waved her hand: "Come and sit down."

Kanao walked stiffly to Ikuko's side and then sat down stiffly.

This child... is like a robot.

Yuko felt somewhat helpless. She had encountered Kanao quite often in the Butterfly Mansion, but the girl seemed a bit shy and never dared to talk to her, preferring to avoid her.

After sitting down, Kanao fell silent.

Yuko asked, "Is there something you need?"

The fact that this child is here clearly means he needs to see her.

Upon hearing Yuuko's question, Kanao took a deep breath and said, "Um..."

"Please tell me how to activate the markings."

Ikuko: "..."

Did you all agree to come here together today to ask Ms. Yu Zi for advice?

"As for the markings, Kanao will follow along first..."

"Alright! First up, five thousand push-ups!"

In the courtyard, Tanjiro and the others had found three little girls from the Butterfly Mansion to sit on their backs, and they were undergoing intense training with their shirts off.

Yuko swallowed the rest of her sentence.

Training with Tanjiro and the others?

She couldn't tell.

The thought of Kanao lying there anxiously doing push-ups made her speechless.
