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

Chapter 561 Let's Disorder, The Butterfly Without Form

Originally predominantly blue-purple with iridescent patterns, the blade rippled like ripples on calm water, or as if instantly deconstructed by an invisible hand. It didn't simply shatter, but transformed in a dreamlike way, the prism-like blade breaking apart and connected by a kaleidoscope of soft, multicolored light.

"What the heck?" Yuko blinked, looking confused, and stood up, picking up her Zanpakuto. "Why is it so bright?"

"Oh?" Yoruichi's eyes lit up instantly. She lowered her arms, which had been crossed over her chest, and walked towards Yuuko with Soi Fon, examining the strangely shaped Zanpakuto in her hand with great interest.

"Is this your Shikai? The Butterfly Without Form?" Yoruichi stared at the flowing iridescent colors and the faintly visible prism blade, trying to analyze its characteristics. "It seems to be a Kido-type Zanpakuto."

"Could it be related to creating hallucinations?"

Soi Fon was also astonished, her large eyes filled with disbelief. She had seen many Shinigami's Shikai, but such a dreamlike and unstable form was a first for her.

The flowing light and the elusive blade exuded an indescribable sense of dangerous beauty.

Yuko held the knife hilt in one hand and rubbed her chin: "Too dazzling, I don't think he's my type."

As she spoke, she touched the colorful blade with a curious expression.

The blade was clearly like a prism fragment that you could touch, yet Yuko's fingers passed right through it.

It's amazing, it feels like a phantom.

The multicolored blade was reflected in Yuko's golden double pupils.

……

and many more.

Yuko's eyes widened slightly, and she stretched out her arm and waved it between the blades of her Zanpakuto.

"Wait! How am I supposed to chop someone up?"

Kaka~

As Yuko finished speaking, the prism-like shattered Zanpakuto slowly retracted, its hazy blade solidifying and reconstructing into a Zanpakuto without a tsuba, not much different from its semi-released form, except that a hollow groove had been opened on the blade.

Yuko stroked the blade: "Oh, so now I can cut people."

Yoruichi stared blankly at the scene.

Why are you so obedient even when you're disliked?

Are ordinary Zanpakuto this obedient?

No? Does this Zanpakuto have some strange quirks?

After being asked three questions in a row, Yoruichi was starting to feel numb.

Shaking her head, Yoruichi decided to stop thinking about it and asked directly, "Do you need me to try it for you?"

Yu Zi looked up in confusion: "Try what?"

"Of course, it's the power of the Zanpakuto."

"Ability?" Yu Zi raised an eyebrow slightly. "If it's an ability, it should be good looks, right?"

Yoruichi almost lost her balance and fell headfirst to the ground.

Yoruichi gritted her teeth and clenched her fists: "Do you believe I can kill you with one punch right now?!"

Yu Zi chuckled and said, "Let me get used to it."

As she spoke, Yuko gripped her Zanpakuto and closed her eyes slightly. She could clearly feel the powerful energy contained within the blade, as well as the close connection between it and the girl named Butterfly in her inner world.

She gently swung her Zanpakuto in front of her.

Om-!

As she moved, the blade emitted a burst of multicolored light that quickly enveloped the entire dojo, with large, illusory prism fragments floating around the dojo.

"Wow~" Soi Fon's eyes reflected a kaleidoscope of colors as she looked on with longing. "It's so beautiful."

Soi Fon instinctively reached out and touched the multicolored prism floating in front of her.

Seeing this, Yoruichi pressed down on her hand: "Don't touch it."

This child is incredibly careless to try something without knowing anything about its capabilities.

Soi Fon paused for a moment, then nodded stiffly and lowered her head, her ears turning red.

Is Lord Yoru really thinking of her?

"Ah, that's fine, you can touch it."

Yuko's voice came from the side. When Yoru looked over, he saw her picking at a shard of prism.

"It feels cool and refreshing, which is quite comfortable."

Yoruichi: "..."

She had thought there might be toxins or some other hallucination.

...No, that's not right! That's not the point!

“But…” Yuko scratched her hair, looking down at the Zanpakuto in her hand, “Isn’t it a bit too flashy?”

The magnified prism is not the Zanpakuto itself, but rather an ability manifested by the Zanpakuto; the blade can still be used as a weapon for slashing.

Yoru's eye twitched slightly: "Do you know how many Shinigami live and eat with their Zanpakuto just for its true name and release phrase, practically treating it like an ancestor?"

"You've actually picked the one."

However, with Yuko's command, the vibrant colors around them dimmed somewhat.

Yu Zi shrugged: "There's nothing I can do, this kid is quite obedient."

Yoruichi was about to have a breakdown. Why was her Zanpakuto being so obedient?

Climb out and give this guy a stab!

Yu Zi showed a slightly satisfied expression and commented, "Although it's still quite flashy, it's barely acceptable."

Yoruichi took a deep breath. If she were this Zanpakuto, would she still be able to unleash her power? She'd be lucky not to beat this woman up.

"How does it feel?" Yoruichi's voice carried a hint of danger. "You can't tell anything just by looking. Come, let me see the skills of your 'Butterfly Without Form'!"

She couldn't take it anymore! She was going to give this guy a good beating!

Before she finished speaking, Yoruichi's figure had already vanished from the spot like a ghost, so fast that only a faint afterimage remained.

"Yoruichi-sama!" Soi Fon exclaimed, but Yoruichi was clearly already in the zone.

Yoruichi's speed was astonishing! Almost instinctively, Ikuko gripped the hilt of the "Butterfly Without Form" with both hands and slashed horizontally in the direction she sensed Yoruichi was rushing forward!

Where the blade sliced ​​through, space seemed to be thrown into a lake by a boulder, creating violent, visible ripples and folds. A distorted spatial fault, refracting seven-colored light, instantly formed, like an invisible, irregular prism wall, blocking Yuko's way.

boom!

Yoruichi appeared almost simultaneously before the spatial rift, her fist, imbued with immense spiritual pressure, slamming down. There was no expected clang of metal against metal, no explosive energy collision. Yoruichi's fist seemed to strike a void, ever-shifting swamp.

Something strange happened.

Yoruichi's fist, along with her entire right arm that was charging forward, was not blocked or bounced off the spatial rift the moment it made contact with it; instead, it was... "teleported".

It's like a painting that has been roughly torn in one corner by a naughty child and then misaligned and pieced back together.

Yoruichi's forearm suddenly emerged from a prism not far away. Her fist missed its target, and the resulting gust of wind veered wildly off course, crashing into the dojo floor and cracking it.

Yoruichi's main body, however, remained directly in front of Ikuko, her posture appearing extremely awkward and uncoordinated due to the "misalignment" of her arms.

Yoruichi's pupils contracted slightly, and she quickly withdrew her arm. The displaced image vanished instantly, and her arm returned to its normal position.

She looked down at her fist, then at the gradually calming ripples in the space in front of Yu Zi, her eyes filled with surprise and intense interest.

"This is... a spatial... distortion?" Yoruichi instantly grasped the key point. "It redirected my attack through the prism?"

Yuko herself was somewhat stunned. That move was entirely driven by instinct, yet the effect was unexpected. She looked at the Zanpakuto in her hand, its light shimmering, and felt the strange power emanating from the blade, as if it could pluck strings in space.

"Butterfly...is this what 'disorder' means? Disrupting...the order of space?"

"Interesting!" This time, Yoruichi was not surprised but delighted, a smile of excitement spreading across her face. "Again! Let me see where the limits of this ability are!"

This peculiar ability aroused Yoruichi's strong interest, and she subconsciously forgot that her original goal was simply to beat up Ikuko.

This time, Yoruichi was even faster, her figure almost transforming into streaks of elusive black lightning, launching attacks on Yuuko from all directions simultaneously!

Although Yoruichi possesses a Zanpakuto, Ikuko rarely sees her use it. It seems that she prefers the feeling of hand-to-hand combat to the Zanpakuto.

Fists and legs, accompanied by sharp whistling sounds and solid spiritual pressure, came crashing down like a storm.

Soi Fon, unable to withstand the dramatic change in Yoruichi's spiritual pressure, retreated to a corner.

Yoruichi... got serious.

Is there really no problem?

……

Of course there is no problem.

After obtaining the butterfly's Shikai and achieving the perfect Shikai of her Zanpakuto, Yuuko's spiritual pressure level has been raised to the third-class spiritual pressure level, which is only attainable by captains.

Even if it's not the spiritual pressure of a true captain, it's at least at the level of a top-tier vice-captain.

This is also why Yoruichi went all out.

Although Yuuko's specialty is dealing with direct physical attacks, Yoruichi's movements were too fast, so fast that Yuuko's eyes could hardly catch them.

However, Yuko did not panic; instead, a strange sense of calm rose within her.

She closed her eyes, immersing herself entirely in the connection with her Zanpakuto, lost in the ocean of her inner world. In the Butterfly House on the island, she seemed to see again the butterfly girl sitting on the porch, swinging her toes, playfully winking her purple double pupils at her.

Yuko opened her eyes, and a flash of golden light passed through her double pupils.

She didn't try to capture every specific movement of Yoruichi—it was too fast, faster than her visual limits. She simply swung her Zanpakuto, relying on a keen intuition about changes in spatial order bestowed by her Zanpakuto, and a strange premonition deep within her that resonated with the butterfly.

"Disorder, formless butterfly."

Her movements didn't seem fast, but wherever the blade passed, the space was no longer a smooth curtain, but was instantly cut, folded, twisted, and displaced.

Prisms are scattered haphazardly and out of place throughout this space.

"Oh no!" Yoruichi's pupils contracted sharply. A prism suddenly appeared in front of her, catching her off guard. She couldn't brake in time, and her lightning-fast figure crashed into the prism.

Yoruichi's figure tumbled out from another prism. Her gaze quickly locked onto Yuuko's figure. Her body twisted in mid-air, bypassing the prisms and swiftly arriving in front of Yuuko.

A vicious side kick was about to hit Yuko's waist.

Yuko smiled calmly at Yoruichi, waved her hand, and casually fell backward.

Behind her, a prism swallowed up Yuko's figure.

"What a troublesome ability," Yoruichi clicked her tongue inwardly.

She followed closely behind Yuko, her body disappearing into the prism. However, in a flash, after passing through the prism, she could no longer see Yuko.

“Here you are~” Yuko’s slightly amused voice came from afar.

That location...

Yoruichi narrowed her eyes: "I see. So, the location where you appeared was under your control?"

Yuko held the hilt in one hand and stroked the blade with the other: "I'm starting to think this ability is somewhat interesting. It truly lives up to its reputation as my Zanpakuto."

Yoruichi's temple throbbed, and her fists clenched unconsciously. This guy, he's really realistic; he just thought the Zanpakuto's color was too bright.

Seemingly sensing Yoruichi's hostility towards her, Yuuko clicked her tongue twice and shook her head dismissively: "Give up, the distance between you and me is just too vast."

Yoruichi's temple veins bulged even more violently. This guy!

Get cheap and sell well!

Yoruichi took a deep breath, her eyes scanning the prisms, quickly summarizing the fastest route to get closer to Yuuko.

Since these prisms can affect space, she must be faster than the prisms!

swoosh~

Yoruichi's figure disappeared from the spot once again.

So fast that you can only see a blur; is this Yoruichi's speed?

No, judging from the level of spiritual pressure, the spiritual pressure in her body is already very close. There shouldn't be such an exaggerated difference.

Is it because her spiritual pressure level increased too quickly, and she didn't use it well enough?

Whoosh!

Yoruichi's figure suddenly traversed the entire distance of the dojo and appeared in front of her, delivering a straightforward straight punch towards Yuuko's face.

Yuko blinked.

Wow, that's quite purposeful.

"Die!" Yoruichi's angry voice rang out.

Yu Zi shook her head: "I'm sorry, but as I said, you and I are just too far apart."

The next moment, a prism suddenly appeared at Yoruichi's feet and swallowed her up.

As she plummeted, Yoruichi desperately tried to maintain her balance, but...

It can't stay suspended in mid-air!

Yoruichi hurriedly tried to prop herself up on the floor that the prism couldn't cover, but a powerful suction force came from below, trying to drag her completely into it.

cheated!

The prism does not move within this space; rather, it can appear wherever Yuko wants it to.

Yuko squatted down with a smile on her face.

Yoruichi braced herself against the floor, her face darkening.

Even a fool could guess what this guy was up to.

Yuko stretched out her fingers and pried Yoruichi's fingers apart one by one.

As Yuko grasped the last finger, a pleased smile spread across her face.

"Bye~"

As she spoke, she pried open Yoruichi's last finger.

However, at that moment, Yoruichi suddenly sprang up, her body crackling with spiritual pressure. She managed to break free for a moment, her entire arm shooting up and grabbing Yuuko's arm.

"...Ah?"
