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

"Kurosaki? What's wrong?" Ishida Uryu followed his gaze and frowned. "This is really... a big deal."

The place that should have been the Karakura Town Museum was now shrouded in an eerie thick fog, with only a faint outline of the gate visible.

The museum doors were wide open, like a gaping maw ready to devour its prey, waiting for them to walk right into its trap.

Ichigo glanced around; the streets were deserted, with only the dim yellow streetlights casting a faint glow, creating an eerie stillness.

"I still can't find Auntie."

Renji muttered to himself, "Could something really have gone wrong?"

Ichigo looked at him speechlessly: "You...didn't you just say that it was absolutely impossible?"

Renji picked his nose: "Even horses stumble, and people make mistakes. Who can say for sure?"

Clearly, he still believed in Yuko deep down.

Upon hearing this, Hun immediately started making a ruckus again, waving his arms and legs: "No! We've already lost one little beauty, please don't let anything happen to the great beauty!"

Ishida's lips twitched slightly: "Instead of worrying about the teacher, you should think about how to snatch Inoue and Chad back from the other side later."

When this was mentioned, Ichigo was utterly speechless: "I have no idea what Auntie and that swindler are up to."

"Inoue was kidnapped for no reason, and now the fake kidnapping has become a real kidnapping. We don't even know who the enemy is."

"That wretched brat has completely outsmarted us."

The fake kidnapping turned into a real kidnapping...

"...Kurosaki."

Ishida suddenly spoke, but then stopped abruptly.

Ichigo turned his head in confusion: "What's wrong?"

"No, it's nothing."

Just as Ichigo was about to ask more questions, Renji couldn't help but interrupt their conversation.

"Stop talking so much, let's hurry up and go, it'll be dawn if we keep dawdling." He used both hands to push the two of them from the back towards the museum entrance.

……

Late at night, the streets of Karakura Town.

Long Gui had just finished his extra training at the dojo. Dressed in a white karate uniform and carrying a long bag for holding wooden swords on his back, he was dragging his tired body home.

The streets were deserted, and the streetlights cast a dim yellow glow.

Although she was physically exhausted, she was very excited.

After being praised by Yu Zi at noon today, she felt that she could work even harder, so she practiced more, which even delayed her training for the competition.

Although she still hadn't sensed the spiritual energy within her body as Yuko had said, she did feel herself slowly becoming stronger. Perhaps it was due to the breathing technique; she now felt a significant increase in her strength and energy.

I've had experiences of practicing late into the night for competitions before, and usually my hands and feet would still feel weak the next day. Now, although I'm also very tired, as long as I rest for one night, I'll feel refreshed the next day.

She's been like this for several days in a row.

This is probably the result of what Teacher Yuko said: that her breathing techniques and spiritual power are both improving.

The streets were deserted at night, with only the occasional car passing by, making it very quiet.

"Woooooooo..."

A strange crying sound suddenly came from the alley ahead.

Long Gui paused for a moment, slowed his pace, and slowly walked towards the alley entrance.

As she practiced the breathing technique, her five senses became more acute than before, and her perceptions such as hearing and sight became stronger. She was certain that the crying sound was coming from the alley ahead.

It sounds a bit like a child's voice.

With that thought in mind, Long Gui, his heart pounding, came to the corner and looked inside, following the moonlight.

Instantly, Long Gui's heart, which had been pounding with anxiety, was put at ease.

Beside the wall in the alley, there was a boy sitting on the ground with his legs drawn up to his chest, his head buried between his knees.

She looked to be about six or seven years old.

Did you stay out too late this afternoon and forget to go home?

Long Gui stepped forward and squatted down in front of him.

"Little brother, are you alright?"

The little boy's crying stopped abruptly.

Long Gui reached out to support his shoulder: "Little brother, where do you live..."

Before she could finish her question, the little boy slowly raised his head and revealed a strange smile.

"Big sister, can you see me?"

His lovely face gradually contorted as he finished speaking.

Long Gui's pupils suddenly contracted, goosebumps instantly rose all over his body, and a chill shot up his spine, heading straight for the top of his head.

boom! ! !

After an explosion, dust billowed out of the alley, breaking the silence of the night streets.

Smoke filled the air, and gravel flew everywhere.

Long Gui slid out of the alley and onto the street, his feet leaving two shallow tracks on the ground, until he came to a stop when his back hit a lamppost on the side of the road.

"Cough cough..."

Long Gui coughed up a mouthful of blood. In that instant, the boy's body suddenly mutated, and his right hand reached out to grab her.

At the critical moment, she turned to the side and used the bone knife on her back to block, but she almost lost her balance and was knocked out of the alley.

"Hehehe~ I'm so lucky."

Amidst the dust and smoke, a massive figure approached from the alley, growing larger and larger. Accompanying it was a sharp, piercing laugh.

As the dust settled, it revealed a bloated figure with a mask on its face that resembled a split, man-eating flower.

It's all fake!

"It smells so good, your soul smells so good, even more delicious than ordinary people's." The voice of the shrilly was sharp and piercing, and viscous liquid flowed from the corner of his cracked mouth.

"It's spiritual energy, such rich spiritual energy."

Long Gui's heart was pounding violently, as if it were about to jump out of his throat.

She had just hit half of her body against the lamppost, and it was already a little numb.

This was the first time she had faced this monster alone.

There was no teacher, no Ichigo, and no Orihime.

She could still recall the monster she encountered at school before summer vacation.

The monster attacked her, Orihime, and Chizuru.

In the end, it was Orihime who stood in front of her.

In the end, without a doubt, it was Orihime who saved her.

Is that the enemy Orihime will have to face?

Its size, as tall as a small building, is about the same as the monster I saw in the classroom yesterday, the one that Ichigo killed with a single strike.

Only when you actually stand at its feet can you feel the absolute difference brought about by its size.

Fear, like a cold, venomous tongue, climbs up the spine.

"Terrified?" Xu seemed in no hurry to devour Long Gui, but rather to tease him. "His legs are already trembling."

"Don't worry, I'll start eating you from your feet, so you can really feel yourself being eaten."

"It must hurt a lot, it must hurt a lot."

"Hee hee hee."

Long Gui ignored its teasing, forced himself to shut his mouth, and took a deep breath of cold air through his nose.

The cool night air rushed into my lungs through my trachea with a strange rhythm, as if even my brain began to clear and become lucid.

The muscles, which had been somewhat numb from the fear and impact, gradually regained sensation under the impact of this coldness.

"Are you already terrified?" Xu's voice carried a hint of disappointment.

But the next moment, the Void with the man-eating flower mask let out a piercing laugh, and its huge claws swept down like swatting flies, bringing a foul stench.

"Then go to hell!"

At this critical moment, Long Gui not only did not back down, but instead calmed down.

In Xu's eyes, it was as if she had given up resisting.

call……

Long Gui slowly exhaled a breath of stale air, which condensed into a faint white mist under the cold moonlight.

Zheng!

The white bone knife was drawn from its sheath, drawing a chilling arc across the night sky.

Although she hasn't yet mastered her own spiritual power, nor learned how to wrap it around the blade, this bone sword named Snow Fang already contains Yuuko's spiritual power.

"Forehead……"

Xu only felt a flash of silver light before his eyes. Before he could even see, his claws had already struck the ground, but he didn't feel any impact on anyone.

It opened its eyes, and all it could see was the ground cracked by the slap of a hand.

Long Gui's figure disappeared from the spot.

"Where..."

"Here it is, you idiot."

Long Gui's voice came from directly below Xu, who was startled and quickly looked down.

"Snow Breathing... although I don't know any techniques yet..."

Ryuki gripped the hilt of the sword tightly with both hands. At this moment, the snow-white bone sword seemed to sense its master's crisis and will. The spiritual particles that were originally floating in the air of Karakura Town around the blade seemed to have found an outlet and rushed into the blade wildly.

The originally snow-white bone blade was instantly covered with a faint glow.

"But these are the fangs my teacher gave me!!"

"I also have people I want to protect!!!"

Long Gui let out a roar, exerted force from his waist and abdomen, and delivered a sweeping slash that rose from the ground.

puff!

The bone knife cut into Xu's abdomen, but it didn't feel like hitting rock as I had imagined. Instead, it felt like a hot knife cutting through butter, with almost no resistance.

"Ahhhhh!!"

The creature let out a shrill scream as a huge wound stretched from its abdomen to its chest, gushing out a large amount of blood.

It staggered backward, staring incredulously at the tiny human before it.

Long Gui landed a successful blow, but instead of being greedy for more, he quickly jumped back to create distance.

She looked at the bone knife in her hand, a hint of disbelief flashing in her eyes.

I made it through... I really did it.

"Damn it! Damn bugs! It hurts!" Xu flailed his arms wildly, smashing the surrounding walls to pieces. "What is that thing in my hand?! What is that knife?"

Is it a Shinigami's Zanpakuto?

No, not possible!

While this human's spiritual power is delicious, it's still quite a distance from that of the Grim Reapers.

Moreover, even a Shinigami's Zanpakuto couldn't cut through its body so easily.

A Zanpakuto that can slice through its body so easily must be at least a Shinigami of the Seat Rank.

This human's spiritual power is definitely not at that level.

"Damn bugs!"

Wearing the man-eating flower mask, the Hollow let out a ferocious roar. Blood was still gushing from the huge wound in its abdomen. As the flesh in its abdomen writhed, the wound began to heal... no, not heal, but was enveloped by new flesh.

"Die! Die!" The pain robbed it of its playful spirit, and its massive body, like an out-of-control truck, hurtled towards Long Gui with a gust of wind.

The enormous claws gleamed coldly in the moonlight, blocking all of Long Gui's escape routes.

If it were the old Long Gui, he probably wouldn't be able to do anything but close his eyes in despair at this moment.

But now, the world has changed in her eyes.

In a state of extreme tension and excitement, the cold air inhaled into the lungs felt like an ice scalpel, clearing away all extraneous thoughts from the mind.

My heart was pounding like a drum, but I wasn't panicked; instead, I started to feel excited.

Breathe.

—Don't panic, keep your rhythm. Just like Teacher Yu Zi said, you need to deliver oxygen to every cell in your body.

Long Gui stared intently at the descending claws, as if everything in his field of vision was being slowed down.

She saw it.

Spiritual power!

At this moment, the spiritual energy surrounding Xu's body was clearly visible to Long Gui.

It was a black spiritual energy covering the man-eating flower's body.

Without a doubt, that was illusory spiritual power.

"Sigh~"

A visible wisp of white mist wafted from Long Gui's lips.

Her teacher hadn't taught her swordsmanship yet, but she wasn't without a foundation.

Long Gui did not retreat, but instead charged forward to meet the sharp claws.

Yes, this knife will work.

Long Gui watched without changing her expression as sharp claws came grabbing at her from both sides. In just a moment, her body would be cut to pieces.

Click~

bang~

With a crisp sound, the sharp claws on both hands shattered.

He feigned shock: "How could this be..."

Click~

A streak of white light flashed in its eyes, and the illusory body froze in place.

"How could I..."

A crack began to appear at the center of the mask's brow, and soon the crack spread rapidly until the mask was completely shattered.

"Ah!!!" With a final, unwilling wail, the massive body began to disintegrate, turning into spiritual particles and dissipating in the streets in the dead of night.

This is not a Zanpakuto; it doesn't have the power to grant enlightenment.

This guy is dead as dead as can be.

"Hahaha……"

Long Gui's legs went weak, and he collapsed to the ground. The bone knife in his hand clattered to the side.

She looked at the empty street before her, at the spot where the monster had disappeared, and slowly raised her trembling hands.

"I...won?"

A wave of intense fatigue washed over me, and the bruises on my back began to burn. My vision was also obscured by the blood flowing from my head.

"...Ouch!" Long Gui touched the back of his head and immediately shrank his neck.

It looks like he hit the back of his head when he was thrown against the telephone pole.

Long Gui subconsciously looked at the street lamp, which had been knocked over and was lying on the wall to the side.

Long Gui broke out in a cold sweat. It was a good thing she was a sports student, otherwise she would have been half dead.

She looked around again. The alleyway entrance was a complete mess. It was truly a monster, not even in the same league as a wild beast.

Although I almost died, but...

Long Gui looked down at his palm, where a white ball of spiritual energy was slowly wriggling.

This is spiritual power, her spiritual power.
