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

As a doctor, especially as a doctor in the Demon Slayer Corps, Shinobu Kocho was naturally interested in techniques that could help the Demon Slayer Corps.

This is a medical technique that can save lives.

But this kind of thing is like a martial arts manual; it can't be easily passed on to outsiders, which is why Shinobu Kocho had some reservations.

Sure enough, as soon as she said that, Yushiro, who had just put down his bags and luggage, jumped up.

"Lady Tamayo's medical skills are far superior to yours..."

Tamayo interrupted, "Yushiro, you mustn't be rude."

Yushiro immediately wilted and subconsciously cast an annoyed glance at Yuko. Ever since meeting this woman, Lady Tamayo seemed to have lost her mind, even showing up at places like the Demon Slayer Corps without warning.

Yuko noticed Yushiro's resentful gaze and returned it with a speechless look.

Just as Yushiro was about to break down and question Yuko, Yuko spoke first: "I know that Mr. Yushiro is a cold-faced but warm-hearted person."

"But if you're always acting like a child, no girl will like you."

When he heard the first half of the sentence, Yushiro still had an indifferent expression, but when he heard the second half, his arrogant expression immediately froze.

“Girls would definitely prefer someone with a calm and composed personality,” Yuko added, “If you don’t believe me, you can ask Tamayo.”

"How could this be..." Yushiro's face turned red, and he stammered, his face flushed with embarrassment at his age.

Tamayo said helplessly, "Alright, you two. Yushiro and Miss Butterfly, stay and help out. Ikuko and Miss Yae, please wait outside."

Shinobu Kocho's face lit up with joy: "Thank you, Ms. Tamayo."

Yu Zi rolled her eyes. Well, this guy kicked her out.

Knowing that she couldn't even name all the medical equipment, Yuko left the operating room with Yae.

These days, even odd jobs are considered skilled work.

"Sit by the door, I don't think you can sleep either," Yuko called out to the preoccupied Yae and sat down in the doorway.

Yae sat down next to him, looking somewhat worried: "Yeah, to be honest, I'm really nervous right now."

"Tamayo isn't one to make empty promises. If she says everything's alright, she's definitely confident. Don't worry," Yuko reassured her, then looked up at the stars in the sky.

At night, she likes to stare at the sky in a daze.

The night sky at that time was not yet polluted.

The stars twinkled, like a dream.

"Hello, would you two like some tea?" Kanzaki Aoi, with her twin ponytails, saw Ikuko sitting alone in the corridor and came over with a cup of tea.

Two years ago, when Yuko was a guest in the Demon Slayer Corps, she had a few brief exchanges with this girl.

Yuko asked, "Aren't you going to rest at this hour?"

Kanzaki Aoi sat down next to Yuuko, forming a cheese sandwich with Yae between them, saying, "Shinobu-san is busy, I wanted to see if there's anything I can do to help."

Seeing the girl's effort, Yuko didn't say anything like "Go and rest," but nodded and said, "Thank you for your thoughtfulness."

"Miss Yae, please."

"Ah, thanks."

The three sat idly by the door, talking quietly so as not to disturb the people inside.

Yae had probably already adapted to the night shift and still had pretty good energy, but Kanzaki Aoi was a bit exhausted, nodding off and eventually falling asleep on Yuko's shoulder.

Just as dawn was about to break, the door to the room in the corridor was suddenly pulled open.

Aoi Kanzaki woke up with a start, and the three of them turned around at the same time. It was Shinobu Kocho.

Yae jumped up impatiently: "Is my dad alright?"

Shinobu Kocho took off her mask, looking slightly tired: "It went fairly smoothly, you can go in now."

She moved half her body aside.

"Aoi, please go in and keep an eye on things. If Miss Tamayo needs anything, please let me know immediately."

"Yes, Miss Shinobu." Kanzaki Aoi quickly stood up.

He's a young man with plenty of energy and drive.

Seeing the dark circles under her eyes, Yuko couldn't help but ask, "Are you alright, Shinobu? You don't look well."

"Hmm, I'm a little tired." Shinobu rubbed her temples and sat down next to Ikuko.

"Ms. Tamayo is amazing. I can't keep up at all if I don't concentrate."

"You've had a long night, go and get some rest."

Shinobu Kocho shook her head: "No need, I can still manage."

Yuko laughed and said, "Tamayo's physical strength is much better than that of an ordinary person."

As ghosts, few humans can compare to them in terms of physical strength alone, so the high-intensity energy expenditure of surgery is nothing to them.

Speaking of physical strength, Shinobu Kocho suddenly remembered what happened last night and couldn't help but ask, "That..."

"Hmm?" Yuko looked over in confusion.

"I want to know what those markings that Yuko mentioned are?"

"Stripes?"

"It is a kind of ability that consumes lifespan in exchange for improved physical capabilities."

Shinobu Kocho: "Then, can I awaken my Demon Slayer Mark too?"

"Of course, awakening the markings isn't difficult." Among the three-piece set, the markings should be the simplest one.

All you need to do is reach the limit.

"But as I said, people who awaken their markings usually don't live past twenty-five."

"If I hadn't been turned into a demon, I think I would have died from the mark." Yuko stroked her cheek, a hint of reminiscence in her eyes.

She doesn't consider herself a special person like Yoriichi.

Shinobu Kocho originally intended to ask about the Demon Slayer Mark, but upon hearing Ikuko's murmur, she couldn't help but ask, "How did Ikuko become a demon?"

After saying that, she suddenly felt it was a bit impolite.

"Um, is my question a bit difficult?"

Yuko paused for a moment, then said, "I think so."

Shinobu Kocho was a little dumbfounded, and her ears turned red with embarrassment.

"I was turned into a ghost by... my own brother."

Yuko has forgotten many things, but Yoriichi and Iwakatsu's memories are still intact.

If... if only she had cut a little deeper back then.

If only she had been more careful back then...

Shinobu's eyes trembled slightly, and her lips pursed: "I'm sorry..."

Yu Zi smiled and said, "It's okay. After becoming a ghost, my legs are no longer weak, my throat is no longer coughing, and my body is much better."

She was telling the truth.

The main reason Yuko didn't want to become a demon was that she didn't want Muzan to know her memories.

Of course, as Yoriichi grew older, she also experienced a period of melancholy.

But all she heard from Shinobu was a bitter laugh.

Yuko...it must be very hard for you.

Shinobu's purple eyes held a hint of gentle sadness.

Yuko's expression was somewhat stiff.

What's with that expression... She looks so pitiful.
