Black Nest. Solution

The Black Nest is a lair woven from Yura's demon-powered hair. Beyond serving as a temporary shelter from the elements, its primary function is as a wide-area reconnaissance technique. It perceives the world through vibrations, covering an immense range; if her demon power were sufficient, Yura feels her hair could wrap around the entire planet.

However, if it is too long, the transmission of information requires time, resulting in a certain degree of latency.

Yet, within this range, anyone who falls into it is like a fly caught in a spider's web.

Looking from underground, massive amounts of hair resemble plant roots, knotted and intertwined directly with one another, laid out in a dense, thick mesh that blankets the entire Takigakure.

Doflamingo possesses one of his strongest finishing moves, called the Birdcage.

As an enhanced version of his Parasite strings, it possesses both offensive and manipulative capabilities, with countless threads forming a massive, arc-shaped cage stretching from the sky to the ground.

The threads themselves have an incredibly sharp cutting ability; one only needs to touch them lightly to be wounded. Thus, this move acts like a true birdcage, preventing those trapped inside from escaping.

It can also cause the threads forming the cage to disperse, piercing into the opponent's body to control their limbs, forcing those inside the cage to slaughter one another.

Furthermore, it can block radio waves and other wireless signals, preventing those inside the cage from calling for help.

As for blocking signals, Yura likely cannot manage that yet.

But the other two points are not difficult to achieve.

Walking in mid-air through the dense forest, Yura forms a seal with one hand in front of her chest—a symbolic gesture.

Black Secret Technique. Black Nest...

"Release!"

Everything happens in silence; no one yet knows what has occurred. No, perhaps someone does. Huan, lingering near the Black Nest, inexplicably feels a sense of panic. It feels as if some monster nearby has awakened, its heart beating with a powerful, slow, and deep rhythm.

In a field of vision she cannot see, behind her, the Black Nest—standing like a heart in the forest—is pulsing vigorously. It beats like a heart, pumping blood and transmitting demon power to the strands of hair far and wide.

The hair buried underground vibrates, and the next instant, it breaks through the soil in unison, rushing toward the high sky like dancing meteors.

Viewed from above, the invisible hair circles the waterfall of Takigakure as its center, with endless strands meeting in mid-air, crisscrossing and connecting to one another.

Seemingly sensing the arrival of danger, the entire mountain forest erupts. As the sea of trees trembles, flocks of birds are startled, taking flight to shriek and scatter, blotting out the sky as they flee.

But this is not a Birdcage, and Yura has no desire to trap them.

In the dense forest, one strand of hair after another shoots out from the ground in rapid succession. Some shoot straight into the sky to form the skeleton of the structure, while others weave chaotically through the woods, crisscrossing without aim. As the dense hair dances and weaves, bypassing trees and animals, a leaf of Konoha drifts down. In an instant, as if passed through by something invisible, the leaf is silently sliced into two halves.

At this moment, a squad of four ninjas, acting under the village's orders to search for the jinchuriki, are leaping between tree trunks. Without warning, the lead ninja is sliced into scattered, mangled chunks in an instant, falling from the air with terror and shock still lingering in his eyes. Following him is the second ninja, who silently disintegrates in mid-air, turning into fragments before scattering. Then, the third and fourth ninjas are successively shredded.

With nowhere to land in mid-air and the momentum of their advance, they collide perfectly with the sharp, crisscrossing web of threads, being sliced into pieces one after another by the silently raised net without any chance to react.

Only faint bloodstains remain at the scene, gathering into beads and sliding down the invisible threads, dripping onto the ground.

Cruel and bewitchingly beautiful—this is the art of slaughter.

With Takigakure as the center, the same scene is playing out in one location after another across the vast expanse of the mountain forest. Some scouting ninjas die without pain or awareness—whether that is fortunate or unfortunate, who can say? Other ninjas are not so lucky; they are not sliced into pieces immediately but are fortunate enough to have limbs severed, leaving them alive. Piercing screams erupt in the forest as blood stains the earth.

Some ninjas, after paying the price of their comrades' lives, keenly sense the danger in the forest. They stand frozen in place, faces full of terror, guarding their surroundings and not knowing what to do. There is only the sound of frantic shouting, cursing the attacker to show themselves, while they swing their weapons desperately to defend against the invisible attacks.

But it is all in vain.

The hair descends rapidly, falling like meteors and piercing into the ninjas' bodies.

The next second, two people who were just comrades, standing back-to-back, turn simultaneously and strike a fatal blow against each other. Gaping wounds bloom hideously on their chests. As the two lock eyes, both can clearly see the shock, fear, despair, and helplessness in the other's gaze.

Their limbs are tightly bound by invisible threads, twisted into grotesque shapes.

Their faces are full of collapse, hot tears spilling down, snot streaming.

"No—! It's not me!!! Run! My body isn't under my control!!!"

"No—! Don't!!! Wait! Stop! I beg you—!!!"

At the same time, hot blood spills down.

An invisible cage shrouds the entire perimeter of Takigakure. Demon power boils and churns between the threads, gathering and condensing into a massive, terrifying phantom that cannot be looked upon directly.

Above the mountain forest, a giant, half-body phantom of a woman emerges, her long, pitch-black hair dancing across the sky. A faint smile hangs on her face, her scarlet eyes cold and rippleless. Between her outstretched, massive hands, her palms are held in a hollow gesture, as if the small Takigakure is being shrouded within the shadow of her palms.

Here, passage is prohibited.

In the forest, Little Monster flies with her head down, feeling somewhat uneasy. She can sense the various intense, roiling negative emotions erupting in the distance. Some are in fear, some are terrified, but most are in despair, as if they have encountered an overwhelmingly powerful enemy.

Yura strolls in front, leading the way, and says, "Keep up, Little Monster~ Otherwise, you might accidentally be hacked into eight pieces."

Little Monster obeys, flying closer to Yura.

A moment later, following Yura to a location, she flies in mid-air and looks at the carnage below. Little Monster's pupils shrink slightly.

Even if she always has "hatred" on her lips, in essence, she is just a simple girl who has been secretly imprisoned by her family for years and has never seen blood. This is the first time she has seen human death so directly.

Under a large tree, mangled fragments are scattered all over the ground, and a head with eyes full of terror before death rolls to the side. The only surviving youth in the field is covered in blood, his face blank, standing frozen under the tree, his body trembling violently.

He does not look old, at most eleven or twelve—already a qualified genin cannon fodder.

Not long ago, he was perhaps just a simple child harboring fantasies about the ninja profession.

But Yura knows very well that in the present day, with the Warring States period just ended, a child who has become a ninja at this age is no pushover. Since he wasn't on Huan's list, it means he has already been abandoned.

A jinchuriki beating up a genin—Yura won't even mention who has the advantage here.

Flying in mid-air, Little Monster hesitates and does not launch an attack, her knuckles turning white as she grips the Black Blade.

Yura doesn't really want to force her, but this is the ninja world. Yura doesn't mind letting her recognize reality as soon as possible.

"Hey, you kid over there."

Sitting mid-air with a relaxed posture, Yura offered a faint smile.

"Kill the blonde here, and I'll spare your life. How about it?"

Hearing this, the boy trembled, his head bowed so low that his expression remained hidden.

"Hey! You big monster!" Lucy wasn't stupid; she gripped her blade tightly, her eyes locked onto the boy before her. In her perception, the killing intent rolling off him was growing increasingly violent.

He wants to kill me!

He's serious!

Just like those hateful clansmen!

Her emerald eyes turned blood-red in an instant. Lucy bit her lip hard, but...

Lucy's hands were trembling...

The next moment, the boy lunged into action. With a flick of his hand, a kunai shot out at high speed. Amidst the shrill whistle of the air being torn, the kunai grazed Lucy's cheek, sending a spray of blood into the air. At the very last second, Lucy had instinctively tilted her head.

After all, she was a Jinchuriki; scarlet chakra surged from the wound, and in the blink of an eye, the injury healed.

Whether it was the wings on her waist or the rapid healing of her wounds, this ability was known as borrowing chakra.

The boy's face was filled with murderous intent, and he prepared to attack, eager to strike. However, wary of the invisible blades surrounding them, he didn't make any drastic moves, hoping only that the seemingly foolish blonde would collide with those invisible traps herself and be dismembered into pieces.

"Come on! You stupid blonde!"

"You bastard—!!!"

Consumed by rage, she let her black blade fly from her hand.

The boy stared at Lucy's movement, stunned. She had thrown something—or perhaps nothing at all. The next instant, he realized what was happening, but it was too late to dodge. Invisible blades pierced through his chest, and his body rapidly lost its strength. Intense fear welled up in his eyes, and before he died, a desperate, unwilling shriek erupted from his throat.

Supporting her head with both hands, Yura watched the boy's final struggle.

"Your aim isn't bad. You have quite the talent for being a ninja."

Lucy hovered in mid-air, breathing heavily. Her hands were still shaking, and it took a long while for her to calm her emotions. She kept her head down, saying nothing.

"Being this kind really doesn't suit a monster, Little Monster~"

Hearing this, Lucy snapped her head up, blurting out anxiously, "Who, who, who is kind! I'm a monster! A man-eating monster!"

"Is that so?" Yura stood up, clapped her hands, and said, "Let's go. We're going to meet a man-eating monster."

"A m-m-man-eating monster?!" Lucy's face paled in shock. She took a step forward, thinking, If I meet a guy like that, won't my cover be blown?

"Let's go, Little Monster~"

"It's Lucy!"
