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

There are fundamental differences in physique between men and women, especially in terms of strength.

Under the same conditions, only men can be stronger.

There aren't many female members in the Demon Slayer Corps, and only three of the Pillars exist. Excluding Mitsuri Kanroji, who has a special constitution, the remaining Butterfly Sisters are not known for their strength.

Kanae Kocho's strength is only slightly better than her sister's, but it's not particularly great.

Even among swordsmen below the Pillar level, there are quite a few who are stronger than the two of them.

Therefore, under the premise of slaying evil spirits, the training methods for male and female members are actually somewhat different.

Men are better at building muscle and have an advantage in strength.

Women tend to focus more on physical flexibility, using speed and agility to their advantage.

Kanao's Flower Breathing, which she inherited from Kanae, is a derivative style of Water Breathing and does not require a high level of strength.

Water Breathing is a technique that emphasizes gentle changes, and it can be said to be a technique suitable for most women.

Ikuko couldn't ignore Kanao's request; it was rare for the child to talk to her.

“Mr. Rengoku should be coming today…” Yuko pondered for a moment and said, “If you don’t mind, Kanao can practice with Mr. Rengoku here.”

Kanao actually has better control over her body than Tanjiro and the other two, and her techniques are also more proficient.

He uses a derivative of Water Breathing, and his fighting power is no weaker than Tanjiro's.

The fighting strength of these people is actually very close. Even Tanjiro, who hunted the Lower Rank 5 and became a Pillar, does not have much of an advantage.

Unfortunately, this year's pillar is incredibly strong.

These are the pillars that have been able to rival the first pillar in hundreds of years... no, they should be said to have surpassed the pillars of the Warring States period.

Not everything is better the older it is.

"Mm." Kanao's eyes brightened slightly, and she nodded with a smile.

This child rarely initiates contact with people. When someone greets her, she'll respond with a smile.

If it's an initiation of communication...

Yuko had tried to talk to her before, but the other girl was so scared that she stood there sweating and didn't dare to move. As a result, Yuko was also quite frightened. The two of them stood in the corridor staring at each other, until Shinobu Kocho happened to pass by and noticed them, finally taking Kanao back with her.

After that, Yuko didn't dare to communicate with Kanao much, but after she had contact with Tanjiro and others who were undergoing rehabilitation training due to the Battle of Natagumo Mountain a while ago, she changed a lot.

Although Yuko didn't know what had happened, she figured it must have been influenced by Tanjiro. You could say he's got the protagonist's charm, right?

What the Butterfly Sisters could never do, a stranger accomplished.

"You're here." A gentle voice came from afar. Shinobu Kocho looked at the three people training hard in the corner of the yard and smiled slightly. "You're really energetic."

Kanao turned her head and greeted, "Shinobu-neechan."

Ikuko: "...Nin."

Shinobu Kocho sat down on the other side of Ikuko, forming a cheese sandwich between her and Kanao.

Yuko's body stiffened; she should have moved to the side and leaned against the pillar.

Ever since she spoke to Shinobu Kocho in her dream on the Mugen Train, she hasn't been doing well.

As the saying goes, what you think about during the day you dream about at night.

Nightmares may create false dreams, but they cannot deceive the dreamer's mind.

Yuko's hesitation is the best proof; she probably really has a special feeling for Shinobu, but she instinctively doesn't want to think about it.

That's why you seem restless.

Fortunately, it's a trio, so if one of you doesn't speak, the other won't either. In front of two teammates who can't seem to have a conversation, even Shinobu Kocho couldn't start a topic.

The three sat in the corridor basking in the sun, looking serene and content.

If one could ignore Yuko's somewhat stiff body...

"Is anyone home?"

A loud and enthusiastic sound came from outside.

Yuko had never liked such an overly enthusiastic voice before, and she breathed a sigh of relief as she jumped down from the veranda.

Rengoku Kyojuro was a very magnanimous person. He immediately bowed ninety degrees to Yuuko and said, "Miss Yuuko, I'm here to trouble you!"

Yuko waved her hand: "It's okay."

Kyojuro Rengoku glanced around: "If we're going to train, is this the place?"

"can."

The Butterfly Mansion's courtyard is very large. Tanjiro and the other two only train on the very edge. The open space is more than enough for them to practice, as long as she doesn't use a super-large-scale sword technique like Moon Breathing.

"Then I'll leave it to you!" Rengoku Kyojuro bowed deeply to her once again.

This made Yuko a little embarrassed.

"Wait a moment." Yuko returned to the corridor and took off the Nichirin Blade from her waist.

Shinobu Kocho reached out her hand, and she instinctively offered it to him. By the time she realized what was happening, Shinobu Kocho was about to withdraw her hand.

Faced with resistance from Yuuko, Shinobu looked at her with suspicion: "Yuuko?"

“…It’s alright.” Yuko quickly released the Nichirin Blade and returned to the open space.

After standing there for a while, she realized that she seemed to have forgotten something, and turned to look at the corridor.

Kanao was looking at her expectantly.

This child... is so indecisive!

Yuko waved helplessly at her.

"Come here, Kanao."

"Ah."

Kanao Butterfly then stepped down the corridor and walked briskly to Kyojuro Rengoku's side.

Yuko took the initiative to explain to Kyojuro, "This child also wants to try to activate her markings."

Kyojuro's eyes lit up slightly, and he gave Kanao a thumbs up: "I see, let's work hard together!"

Kanao: "..."

Socially anxious people meeting each other is a classic case of socially anxious people.

Yuko's lips twitched as she looked at Kyojuro: "I'll add one more thing: once you activate your mark, you won't live past twenty-five. Mr. Rengoku, are you prepared for that?"

Both Ikuko and Ubuyashiki have emphasized this point.

However, in formal settings, Yuko would still ask an extra question to respect their opinions.

Kyojuro waved his hand without wavering: "Of course!"

"I know……"

"How cunning! How can they do that!" Inosuke suddenly shouted, almost knocking the Butterfly Mansion trio off his back.

He dashed up to Yu Zi like a wisp of smoke, his blue hooded head staring straight at her, two plumes of white steam billowing from his pig-head nostrils.

"I'm coming too!"

Ikuko: "..."

She had forgotten about this guy's personality.

"Ah, Inosuke, we can't let Miss Ikuko be in a difficult position." Tanjiro caught up and stopped Inosuke.

Zenitsu put all his strength into it, shouting, "That's right, you idiot, come back here!"

Yuko sighed, "It's okay."

Zenitsu turned his head and said, "Miss Ikuko, I'll get rid of this guy right away!"

Yuko scratched her earlobe: "I mean, it's okay, the three of you can join too."

She didn't want to be told that she was being unfair or biased.

"Great!"

"really?"

"Eh?!!"
