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

"But then again, you're really a good younger brother to join the Demon Slayer Corps even without the talent to become a swordsman," Yuko said with a sigh.

Genya Shinazugawa, who had just been feeling depressed, suddenly exploded, stammering, "Who! Who are you calling a good younger brother?!"

"See? They're so nervous they're talking nonsense." Yu Zi spread her hands, looking helpless. "They're all so unreliable."

"Enough with the nonsense!" Shinazugawa Genya's neck was flushed red. "Get out of my way!"

That woman! She's really annoying!

At that moment, Shinobu Kocho suddenly spoke up.

"To be honest, I don't want him to join the Demon Slayer Corps. My brother... Genya, as long as he settles down, starts a family, has children, and lives to old age, that's fine."

Upon hearing this, Genya Shinazugawa's pupils contracted slightly.

Shinobu Kocho smiled gently: "You brothers are all so dishonest."

Fortunately, that idiot Mr. Shinazugawa still confides in his sister about some things.

Shinazugawa Genya gritted his teeth and turned his head away: "No way, my brother would never say such a thing, because..."

Because he had clearly said some very hurtful things to his brother at that time.

Yuko had already heard about the Shinazugawa family from Shinobu.

The mother turned into a demon and killed her other younger siblings. Sanemi only had time to protect Genya and fought his demon mother with a kitchen knife.

Because it was dark and he couldn't see clearly at the time, Genya witnessed his brother 'kill' their mother after dawn, and then told Sanemi that he was the murderer.

Although Tanjiro didn't understand what had happened, he still gently stepped forward and patted him on the shoulder.

“Genya, I think Mr. Shinazugawa must love you.”

Shinazugawa Genya's eyes darted around, his jaw trembling.

I'm sorry...

"What do you mean? Wasn't the brother with the rooster-like haircut nice to him?" Inosuke, having finished breakfast, came over with a silly grin. "Do you want us to beat him up for you?"

"No way! My brother is so good to me..." As he spoke, Shinazugawa Genya's face twitched, and he scoffed unhappily, his eyes flickering with uncertainty.

Perhaps he already has the answer.

But his arrogant personality still made him stubbornly ask, "It's not like you have a way to make me stronger."

After all, he was different from the others. He didn't have the talent for swordsmanship or breathing techniques. He only used his Nichirin Blade to roughly chop the necks of demons, and he couldn't perform any sword forms at all.

He is someone who cannot be taught at all.

Even Mr. Himejima only taught him physical and mental training, and his improvement in strength was limited to physical exercise.

Hearing such words means he has already believed them.

“Yes, this is indeed my first time encountering a Demon Eater.” Yuko’s crimson double pupils swept over Shinazugawa Genya as if she were scrutinizing him.

Those peculiar eyes inexplicably weighed on Shinazugawa Genya's heart, as if he were being watched by some terrifying monster.

Yesterday, because I was mostly angry, I only glanced at her briefly.

It now appears that Genya Shinazugawa's physical condition is quite unusual.

Specifically, this manifests in its amazing bite force and powerful digestive system.

A demon eater is someone who consumes the flesh, blood, or hair of a demon—that is, its body tissue—to achieve a 'demon-like' state, giving the human body the regenerative and combat abilities of a demon.

However, this is not an ability to become infinitely stronger by eating demons; it only grants him the ability to temporarily transform into a demon.

Once the digestive system has completely digested the demon's body tissues, the intensity of the demonization will be greatly reduced.

In other words, he couldn't maintain his peak condition to face the enemy like others.

Instead, they need to obtain body tissues from enemies during battle to strengthen themselves.

Hearing Yuuko's words, Genya Shinazugawa felt a pang of disappointment and frustration, and said unhappily, "Then don't..."

Yuko interrupted him: "Although I don't quite understand the principle, with me, you should become stronger much faster than Tanjiro and the others."

"Huh?" Shinazugawa Genya frowned.

Yuko didn't keep you in suspense: "Because I'm a demon, and a demon that can rival an Upper Moon demon, my body tissue should be able to make you stronger, right?"

……

After a moment of silence, the veins on Shinazugawa Genya's forehead began to bulge.

"Do you think I'm an idiot?" he gritted his teeth, pointing outside. "Hasn't the sun already risen?!"

The little devils over there are all sleeping in the boxes.

Yuko tilted her head: "Can't you feel it? My presence?"

"What? It doesn't feel right..."

Genya Shinazugawa's agitated expression suddenly froze. All the sounds around him seemed to vanish instantly, leaving only a silent terror before him.

His pupils trembled as he looked up. Yu Zi's alluring figure was shrouded in darkness at some point, and the ghostly aura emanating from her was so thick that it was hard to breathe, as if every cell in his body was trembling.

It's a ghost...

A real ghost.

And... it was stronger than any he had ever encountered before...

There was even a demon who had overcome the effects of sunlight and was now with a Pillar of the Demon Slayer Corps.

How is this possible!

Not many members of the Demon Slayer Corps knew Yuuko's identity. Apart from the Pillars, only two members of the logistics unit who were present at the Pillars meeting knew it, and the Master had instructed them not to reveal it.

Even if Ubuyashiki believes that the children of the Demon Slayer Corps would not have any intention of betraying the Demon Slayer Corps, necessary measures still need to be taken.

Genya Shinazugawa, having always been by Gyomei Himejima's side, naturally had no way of knowing this.

In a daze, that indescribable aura vanished instantly.

Genya Shinazugawa was panting heavily, his back already soaked with sweat.

"Now you should understand what I mean, right?" Yuko said calmly. "Tanjiro will tell you the details."

"Have you finished breakfast?" Yuko asked, glancing at Zenitsu, who looked listless.

Zenitsu opened his mouth with difficulty: "I have no appetite."

Yu Zi nodded silently: "That's good, then I won't throw up during training later."

Tanjiro was so scared he was in the drawing, so what will the training be like later?

Will people die?

Zenitsu's face grew even paler, while only Inosuke, that idiot, looked full of energy.

"Oh!! I'm going to beat you today, you woman!"

Yu Zi smiled: "Yes, it's a good thing to be motivated."

Everyone: You feel even more excited when you beat me up, right?!
