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

Yuko turned around in confusion: "Why?"

Uzui Tengen glanced at her sideways: "Isn't that brat your stepson?"

"Just keep an eye on him."

"Who exactly is saying that Tanjiro is my stepson?" Yuko raised an eyebrow, somewhat speechless. "Besides, I'm not a Pillar."

“It’s just a way of saying it; you could call him master and disciple if you want,” Yuzui Tengen changed his tune. “But I think you care about him even more than his actual master does.”

"Is that legendary Initial Breathing really that powerful?" At this point, Uzui Tengen couldn't help but turn his head and ask.

It deserves this much attention.

Yuko suddenly stood still, looking up at the night sky.

Uzui Tengen: "Hello?"

"...Maybe it's not that strong." After a long while, Yuko took a deep breath.

At least... she couldn't feel any sense of security from Tanjiro.

Perhaps it's age that limits physical growth; even though Tanjiro has awakened his Demon Slayer Mark, he's still too weak for Ikuko.

There's very little we can do to help.

Being able to go toe-to-toe with the Upper Moon One at this age is already quite impressive, but perhaps Yuko had too high expectations for him. She felt that someone who could use the Breath of the Sun shouldn't be so weak and should be even stronger.

Thinking of this, Yuko couldn't help but laugh at herself.

He's lived for hundreds of years in vain and still can't beat Kokushibo and Muzan, yet he insists on pinning his hopes on the 15-year-old 'protagonist' Tanjiro. How shameful!

Seeing her somber expression, Uzui Tengen was at a loss for words.

The two returned to the Teng family home in silence.

Upon returning to the Fuji family home, Yuko immediately ripped off the hairpin from her head, letting her long, flowing red hair cascade down, taking away the weight on her head.

Yuko changed out of the heavy kimono into her own clothes, feeling as if she had been freed from all her shackles, and her breathing became easier.

She clearly prefers wearing these lightweight clothes.

Back in the contact room, Uzui Tengen changed back into his usual attire, carrying two Nichirin swords on his back.

"Anyway, I'm leaving that kid in your care." Seeing Yuko walk in, Uzui Tengen shrugged. "The Fujii family has reserved a room for you. Remember to come back and report tomorrow."

"Also, take them with you. Release them in case of an emergency."

"What?" Yuko was stunned when Yuzui Tengen walked towards her and opened his large right hand, revealing his palm...

mouse.

He wore a gemstone band similar to that of Uzui Tengen on his forehead, and stood on his palms with both feet.

This is the ninja beast 'Muscle Rat' sent by Uzui Tengen. It has undergone special training and possesses extremely high intelligence. Its strength is so great that it can easily lift a Nichirin Blade weighing several kilograms.

Yu Zi pursed her lips, feeling somewhat nauseous: "What a disgusting rat."

Yuzui Tengen broke through his defenses and roared, "What kind of taste do you have, woman?!"

"Look at that magnificent posture?! Look at those beautiful curves of her body!"

As he spoke, the mouse in his palm cooperated perfectly, displaying its biceps and back muscles like a bodybuilding champion.

"Say it! Did you see that?!"

"How disgusting..." Yu Zi took two steps back, her facial expression giving the impression that she was about to vomit.

Yuzui Tengen was instantly petrified.

The muscle rat squatted in Yuzui Tengen's palm, drawing circles, its confidence plummeting.

"That's enough! I'm leaving!" Yu Zui Tian Yuan said angrily, preparing to leave.

Yuko suddenly called out, "Wait!"

"What!" Uzui Tengen turned around irritably.

Yuko's expression turned serious as she cautioned, "Be careful, the demon here could very well be an Upper Moon demon."

"If you encounter one, remember not to linger in the fight."

Uzui Tengen was taken aback for a moment, not expecting this woman to be quite... well, you'd be wrong!

Uzui Tengen roared in fury: "You're underestimating me, aren't you?!"

"You're underestimating me, aren't you!"

Yuko asked expressionlessly, "So, how do you think you compare to Kyojuro?"

Yuzui Tengen paused, then gritted his teeth and said, "I understand!"

I've heard from my lord about the battle where Upper Moon Three was killed for the first time in over a hundred years.

According to Kyojuro himself, if he were to face him, he would probably die there.

Because by the time both sides were firing on all cylinders in the second half, he could no longer clearly see the moves from either side.

Among the Demon Slayer Corps, he felt that only Mr. Himejima could reliably defeat Kyojuro.

This indirectly reflects that Upper Moon is indeed very strong.

Uzui Tengen accepted the promise and turned to leave, but Yuko suddenly reached out to stop him.

"What again?!"

Yuko calmly extended her hand: "Give me the mouse."

"It's a muscular rat!" Uzui Tengen corrected her impatiently, placing the muscular rat in Ikuko's hands.

Yuko felt the mouse moving in her palm, then looked up and asked, "Do you have a box or something?"

Yuzui Tengen turned his back on her and stormed off.

Yuko looked down at the two muscular rats staring back at her, and after a few more glances, they actually seemed quite pleasing to the eye.

Yuko took the two mice and headed towards the Tokitoya.

As night deepened, the shop was incredibly noisy. The owner saw off two drunk customers in front of the shop and then went back inside to get busy.

You can't see what's inside at all.

While the Transparent Realm possesses a certain degree of X-ray vision, it is limited to the human body. It works like an X-ray through a layer of clothing and cannot penetrate walls.

Sending someone in would definitely be better.

They just need to be able to react promptly when unexpected situations arise.

Yuko stood on the roof of the Tokitoya, looking around to confirm the directions of the other two houses.

Although Tanjiro's side is the most likely, the support from the other two sides should at least be in place.

To be honest, she originally wanted to ask Uzui Tengen.

His three wives worked in three different shops, and all three of them have lost contact, which means that the ghost is paying attention to all three shops.

Otherwise, it couldn't be such a coincidence.

Is this aiding and abetting a tyrant?

Are there humans colluding with evil spirits?

Yu Zi sat quietly on the rooftop. Over the years, she may not have learned anything else, but she was definitely number one in the ability to daydream.

If a monk were to challenge her to a meditation contest, to see who had better concentration, she could sit there obediently for dozens of days without moving.

Nothing was said that night. After watching Tanjiro walk out of the shop early in the morning, Yuko turned and left to meet up with him.

"I haven't found anything yet."

"Same here."

Things aren't going too smoothly since I'm new here.

Uzui Tengen pondered to himself, "So it really is the Upper Moon?"

This method of concealing one's presence is indeed unlike that of ordinary demons or lower moons.

Yuzui Tengen instructed, "Continue to investigate. If there is any urgent matter, have the muscular rat notify me immediately."

"understand!"
