Naruto : The ultimate Troublemaker

Kaguya clenched her teeth as her severed arm began to regenerate at a terrifying speed, her chakra pulsating in the air with an intensity that made the ground tremble. She took a slight step back, her eyes scanning Shikai cautiously. He remained motionless, hands in his pockets, a cocky smile on his lips.

"So, Kaguya? Starting to tire already?" Shikai taunted with a mocking tone.

Furious, Kaguya remained silent and suddenly extended her hands towards him, releasing a torrent of lightning that crackled in the air before striking him. The lightning tore through the ground, causing successive explosions, but Shikai dodged each attack with an astonishing ease, his movements fluid and swift.

His Sharingan, glowing red and vibrating with energy, allowed him to anticipate every move. When a bolt of lightning hit him squarely, his body once again burst into a cloud of black butterflies that scattered in the air before reforming intact a few meters away.

"You're wasting your energy," he said calmly, making a gesture to brush off his jacket. "If you keep this up, you'll destroy yourself."

Kaguya frowned. It was clear he was mocking her. He wasn't even countering seriously, preferring to simply toy with her nerves.

She growled, and her hair elongated, transforming into a multitude of sharp spines. With a swift gesture, she projected the spines towards Shikai at an incredible speed. The spines flew through the air, piercing the ground and rocks around him.

Shikai dodged once more, each movement calculated, moving with almost supernatural grace. A few spines seemed to touch him, but each time, his body transformed into black butterflies that evaporated in the air before reforming elsewhere.

Kaguya clenched her fists, frustrated.

"You dare to underestimate me...?" she murmured, a murderous glint in her eyes.

She raised her hands to the sky, and an intense light erupted from her palms. Thousands of gigantic fists made of chakra appeared around her, floating like suspended meteors.

"Try dodging this, vermin!" she roared, launching the destructive fists towards him.

Shikai narrowed his eyes slightly, but did not move immediately. The first fist struck him, causing a massive explosion that raised a cloud of dust. But as the dust cleared, Shikai was nowhere to be seen.

"Like a cockroach!" exclaimed Kaguya, witnessing Shikai appear twenty meters away, dodging another fist.

But the fists kept coming, ten, twenty, fifty at a time, rushing at him like an incessant rain. He dodged, turned, leaped, but one blow finally hit him, sending him crashing to the ground with such force that the earth collapsed beneath him, creating a crater.

Kaguya smiled, satisfied.

"It's over."

But before she could savor her victory, a white and ethereal palm suddenly appeared and struck her violently in the back, propelling her into the air. She stabilized quickly, but before she could react, she felt an invisible force pulling her towards the ground.

She crashed heavily, and at that moment, hundreds of black lances burst forth from the earth and descended upon her like a rain of death. Kaguya rose urgently, releasing a wave of chakra to destroy the lances before they could reach her.

"What...?" she murmured, disoriented.

Her chakra seemed disordered, uncontrollable. She felt an immense pressure bearing down on her, as if she was trapped in a dimension where she had no control.

Then, a loud thud sounded, and through the dust, a colossal silhouette emerged.

A gigantic Susanoo stood before her. Its dazzling white color was adorned with green patterns, and black tomoe adorned its armor. Two immense wings stretched behind it, shining brightly. Around the Susanoo, thousands of spheres of truth floated, pulsating with pure energy.

At the center of this seemingly divine entity stood Shikai, still calm, hands in his pockets.

His left eye, black, displayed a unique Mangekyō Sharingan with a pattern of three curved crosses forming a star at the center. His right eye, equally black, shone with a golden floral motif, the Tenseigan, radiating celestial chakra.

"This is what happens when I'm forced to get serious," he stated in a frigid tone, his eyes fixing Kaguya with a menacing intensity.

Kaguya took a step back, a cold sweat running down her neck.

"What is this...?" she murmured.

Shikai shrugged. He had combined the Yin stigma and the Moon stigma. It was far beyond what she could comprehend or confront.

Kaguya clenched her teeth, her gaze shifting between the imposing Susanoo and Shikai at its center.

"No matter what you are... I will destroy you!" she screamed, releasing all her chakra. After all, she had done everything she could to kill her former master Ishiki, she would never return to slavery, rather die. But before he would take her with him at all costs.

Shikai, at the center of his Susanoo, remained motionless. The spheres of truth around him began to vibrate intensely before speeding towards Kaguya, transforming into lances.

She attempted to defend herself, but the spheres pierced her defenses as if they didn't exist, striking her body with crushing force, tearing through her form. Her body, struggling to regenerate, was a mass of flesh with her chakra in disarray after the Susanoo's palm strike.

On the ground, bloody and breathless, Kaguya raised her eyes towards Shikai, her chakra wavering.
