Crossover Anime: Starting with Bankai from Demon Slayer

The decaying leaves and mud underfoot felt like they were stained with blood, sticky and slippery.

The thick, eerie aura in the air made people dizzy and disoriented.

Lingyuzi has been running around in these mountains for three or four days.

Suddenly, an unsettling smell reached her, and she abruptly stopped in her tracks.

Looking up, several wisps of pale spider silk, almost blending into the thick fog, were silently hanging down from above.

Although it looked light and airy, Ling Yuzi knew that once she was entangled by that thing, she would be torn to pieces and there was no way to escape.

"Tsk..."

She spat in annoyance and clumsily jumped back, avoiding the spider silk that entangled her.

These past few days, she's been like a lost moth, wandering aimlessly in this perpetually shrouded mountain, struggling to avoid the ever-present insect net.

It all stemmed from my own curiosity.

A few days ago, she met the disheveled Rokuro-senpai in the countryside of Fukushima.

Seeing that uncle who always acted like an adult being beaten up like a stray dog, Lingyu felt a little smug.

As for the other party's warning, it sounded more like a lecture from an old man whose old ailment had relapsed—probably taking advantage of her being a newcomer and hiding some valuable stuff...

Please, we're all ghosts who've been around for less than a hundred years, why are you pretending to be Abe no Seimei?

In addition, Rokuro-senpai specifically mentioned that this Lower Moon Five was favored by Lord Muzan, which made her a little jealous.

"So what if I'm a lower-ranking soldier? I'm a lower-ranking soldier!"

So here she is.

However, her lightheartedness and arrogance were quickly shattered by a little boy wearing a white kimono and with strange long white hair.

"Are you...lost?"

He appeared abruptly in the misty air, sitting on a thick spider silk, gently swinging his legs.

A deathly pale face, empty, lifeless eyes, and bloodless lips.

Lingyu had to admit that she felt a lot of pressure the moment the little boy appeared.

Compared to Rokuro-senpai, this guy's aura is much stronger!

Who is he?

"I say, did you get lost here, Lower Moon demon?" he spoke again, his voice even carrying a childlike innocence, but his tone was truly chilling.

Lingyuzi paused for a moment, and although uneasy, she still raised her head and tried her best to maintain her dignity as a ghost month:

"Wait...are you kidding me! I'm the Fourth Moon of the Lower Moon! How could I get lost?"

"I...I was just taking a walk, I won't bother you anymore..."

She tried to avoid the boy's view, but was stopped in place by a web made of strands of spider silk:

"Lower Moon Four... are you very strong?"

The little boy brushed aside his long bangs, revealing blue eyes that looked like glass beads.

[Part 5]

As expected! It's the waning crescent moon of the Ghost Moon—exhausting!

Seeing the other person's cold gaze, Ling Yuzi spoke somewhat hesitantly, "Of course! I... I'm much more capable than a brat like you!"

Lei nodded, and said in a light tone, "That's wonderful... Would you like to become my family?"

"Daddy protects Mommy, Mommy protects the children, and older sister protects younger brother... Since you're so amazing, why don't you be my older sister?"

Huh? Family? Sister?

The last time Lingyuzi heard this term was decades ago, when she was a young lady from a wealthy family.

Those stupid guys simply don't deserve to be her family. Only a powerful and beautiful man like Lord Muzan is the kind of family that Reiko wants.

But then again, what does this kid mean...? Does he want to be friends with me? Or what?

He does seem quite powerful, and... he's favored by Lord Muzan. Maybe if I get closer to him, I can get some benefits too?

At the very least, Lingyuzi wanted to know why he was valued by the adults.

"Okay." She hesitated for a moment, but still agreed. "Being family during two Ghost Months doesn't sound bad, does it?"

Lei's empty eyes seemed to light up for a moment, but quickly disappeared.

"Great..." He lightly jumped down from the spider silk and landed in front of Lingyu. "Let's play a game, sister..."

"A game?" Lingyu was taken aback again.

"Yeah, hide-and-seek." Lei nodded, a chilling anticipation creeping onto his pale face. "You hide, I'll find you... and if I catch you..."

He tugged at the spider silk in his hand, and the ominous aura emanating from it sent a chill down Ling Yuzi's spine.

"...I will peel off your face and make you look like me, sister."

Lingyu's heart skipped a beat; she realized she might have really misunderstood Rokuro-senpai...

But before she could think it through or refuse, the figure of the exhausted woman had already become eerily blurry, like a wisp of mist being blown away, leaving only that light, fleeting sentence echoing in the woods:

"The game has begun, big sister. Hide well..."

From that moment on, the nightmare began.

Lingyu initially looked down on the game, thinking that it couldn't be that difficult for a little kid.

He activated his Blood Demon Art, causing vines to sprout beneath his feet, carrying him swiftly through the forest as he tried to escape the area.

Her abilities include manipulating and activating plants, and releasing toxins that are either deadly or beneficial to herself. Her body is far stronger than that of ordinary ghosts.

However, no matter how fast she ran, no matter which direction she chose, the forest had become a huge, endlessly looping corridor from which she could not escape no matter how hard she tried.

The ubiquitous spider web traps are extremely sharp; even the slightest touch could cut through her skin, which is that of a ghost moon!

She could only rely on her ghostly physical abilities and her perception of plants to dodge precariously through the increasingly dense spiderweb maze, ending up in a sorry state.

Is this kid really Lower Moon Five? Why is he so strong?

"Sister...where are you?"

A childlike, innocent call, tinged with eeriness, drifted from the depths of the mist, sometimes to the left, sometimes to the right, sometimes in front, sometimes behind, as if right beside him, yet also as if far away, sending chills down Ling Yuzi's spine.

However, it's unclear whether it was divine intervention or Muzan's blessing.

Since yesterday, human presence has been gradually detected in this mountain.

Are they the Demon Slayer Corps? Or just ordinary hunters going into the mountains? Reiko wasn't sure, but it certainly relieved a lot of her stress.

She could feel that her attention was being diverted due to exhaustion, and the spider silk attack was becoming less intense.

Perhaps compared to dealing with intruders, making things difficult for myself during Ghost Month is really unnecessary...

Having dodged yet another trap, Lingyu suddenly plunged into a dense thicket, escaping Lei Na's less attentive probing.

Had she escaped unscathed? Her tense nerves relaxed slightly.

No, we'd better leave quickly; this place is definitely a bit eerie...

...Fate seemed determined to play tricks on her.

Before she could find a way to escape, a sharp aura brushed past the grass and trees she could sense and rushed straight toward her.

Huh? She turned around and saw a emerald green blade flashing before her eyes!

Swish! !

Ling Yuzi tried her best to dodge, but the tip of the knife grazed her cheek, leaving a deep cut that went deep into her flesh!

Crimson blood gushed out, and Ling Yuzi was so frightened that he scrambled to his feet and looked at the person wielding the knife.

The colorless blade gleamed in the moonlight, and the man holding it had his gaze fixed on her body as if he were looking at an inanimate object.

"You dodged it?"

He shook the ghost blood off his blade, and a powerful breath returned from his mouth and nose—

"Wind Breathing - First Form..."
