Naruto : The ultimate Troublemaker

In the void of the dimensional rift, a colossal chakra trembled reality itself. A gigantic silhouette emerged slowly, defying the laws of nature. The creature that appeared was a bizarre amalgamation: a serpentine body, covered in pulsating dark veins, intertwined with robust legs reminiscent of a toad. An enormous tail, akin to that of a salamander, lashed the air with brute force.

The beast possessed a terrifying skull, adorned with circularly implanted pupils, alternating between Byakugan and Sharingan that seemed to move and observe erratically. At its center, two colossal eyes dominated: a brilliant golden Tenseigan and a purple Rinne Sharingan, adorned with twenty-seven tomoe, pulsating.

Its misshapen face seemed capable of devouring the entire world, and its gaping maw leaked corrosive black drool that evaporated upon touching the ground. A deep, primal roar reverberated, shaking everything around it.

Mikoto, perched atop her broken Susanoo, gazed at the creature with a mixture of awe and fear.

"What... is that?" she murmured, her voice barely audible.

Kaguya, however, reacted quite differently. The appearance of this being seemed to evoke a visceral fear in the chakra goddess. Her body reacted involuntarily, almost immediately transforming into her rabbit form. Her long ears pointed backward, and her massive, bijuu-faced body vibrated with an uncontrollable rage.

"Why is its summoning here?" Mikoto asked, even more bewildered by the strangeness of the situation. Remembering that she had seen the data of this beast in the laboratory.

Kaguya, now in her rabbit form, unleashed a series of destructive attacks upon the creature. Massive fists of chakra erupted, All-Killing Ash Bones pierced the air, and a deluge of techniques rained down on the beast.

But the Batrachian Dragon, as Mikoto instinctively named it, seemed unaffected. Its multiple eyes flickered erratically, and in a swift movement, its powerful limbs grabbed Kaguya by the arms.

The golden Tenseigan at the center of its skull shone intensely, concentrating a pure luminous energy that was released as a gigantic beam. Kaguya attempted to absorb this attack, but the density of the chakra was such that it pierced her defenses, literally cutting her in two.

Kaguya, despite her state, quickly regenerated, her silver body resuming its form. But before she could retaliate, the dragon's enormous fists crashed down on her with an incredible force. Each blow resonated like thunder, and the frozen ground beneath them cracked further.

The Rinne Sharingan of the Batrachian dragon suddenly illuminated, and Kaguya was thrust into an unstable state. Her rabbit form, though powerful, seemed to struggle to maintain its integrity.

Despite this, Kaguya redoubled her efforts, summoning everything she had to try and defeat the beast. But the invocation wasted no time.

In a split second, the creature used Amenominaka, tearing reality to return to its original world.

Back in their dimension, the sky was still dominated by the reddish moon and the Infinite Tsukuyomi. However, the beast showed no hesitation. It held Kaguya firmly, despite the divine strength she exerted to break free.

A strange black chakra, almost imperceptible, emanated from the creature with each blow it dealt to Kaguya. This energy disrupted her tenketsu, rendering her unable to manipulate her chakra. Even in her goddess form, she was powerless against this opponent.

With a terrifying fluidity, the beast opened its gaping mouth and swallowed Kaguya in one gulp.

Once Kaguya was absorbed, the Rinne Sharingan of the dragon shone once more. A wave of energy traversed the dimension, dispelling the Infinite Tsukuyomi and returning the moon to its normal state. The world seemed to breathe again, freed from the oppressive grip of Kaguya's ultimate technique.

Mikoto observed in silence. Her breath was short, and her body, exhausted from the battle, could only tremble slightly.

It slowly turned its massive head towards Mikoto. Its multiple eyes continued to move erratically, but a clear intent emanated: it had noticed her.

From its mouth, black drool continued to flow, evaporating with a corrosive hiss upon touching the ground. The air around the creature seemed to be charged with an invisible toxicity, and Mikoto could feel the oppressive heat of its breath.

She swallowed hard, her gaze fixed on the terrifying eyes at the center of the beast's skull. Despite her exhaustion, a spark of satisfaction gleamed in her eyes.

"It has awakened..." she murmured, her voice a mix of apprehension and relief.

She knew that only one person could control such a creature.

The beast remained motionless for a moment, its eyes fixated on Mikoto as if judging her. Then, slowly, it opened a portal in reality and disappeared, leaving behind a ravaged battlefield, a heavy silence, and a deeply troubled Mikoto.

Uzushiogakure

In the dark chamber, a stagnant, metallic odor filled the air, betraying the humidity. Rays of light filtered through the cracks in the walls, sporadically illuminating the floor strewn with fragments of broken glass and remnants of a viscous substance. The thick liquid formed puddles around the shattered tube, weakly reflecting the flickering glow of these faint rays.

The solution that had spilled onto the floor seemed almost alive, its ripples caused by the slightest movement. At its center, a silhouette slowly rose from the shattered tube, its bare feet sinking into the debris, crushing the glass and causing a slight, sinister creak.

In the oppressive darkness, only its white hair was visible, framing a face partially masked by shadows. They undulated gently as if animated by an inexistent breeze. The atmosphere seemed to thicken around him, each movement slowing as if he were enveloped in oppressive gravity.

His voice finally broke the silence, hoarse and deep, resonating in the room like an ancient murmur:

"It's been a long time."

Around him, the silence seemed to intensify, as if the room itself was holding its breath. The shadows seemed to move imperceptibly, responding to his mere presence. He instinctively used Meiton.
