Naruto : The ultimate Troublemaker

Kaguya's silhouette suddenly distorted, her chakra exploding into the air like a raging storm. Her form changed, her humanoid features disappearing as she transformed into a gigantic rabbit. Her long ears stood erect, and in her eyes, now two Rinne Sharingan, shone intensely, emitting a terrifying light.

Shikai furrowed his eyebrows as he observed this transformation.

"So, this is it... the mastered form of your true nature," he murmured, his tone laced with contained fascination. He straightened up in his Susanoo, his eyes fixed on the colossus facing him. "It's going to be a fierce battle."

Shikai's Susanoo, immense and luminous, lunged forward, its blazing sword aimed at Kaguya. But before it could reach its target, gigantic arms made of pure energy burst forth from Kaguya's body. They wrapped around the Susanoo like snakes, holding it firmly.

"Insignificant vermin!" roared Kaguya, her voice resonating like thunder.

Shikai clenched his fists as the spheres of truth surrounding him activated, rushing towards Kaguya's arms to destroy them. But each time an arm disintegrated, ten more appeared to take its place.

"You're much stronger than I had imagined."

Kaguya responded by concentrating her chakra in her arms, sending out a devastating shockwave. The impact caused the dome Shikai had placed at the beginning of the battle to tremble, cracks beginning to appear on its surface.

"Tch... She's going to destroy the barrier," grunted Shikai, dodging another attack as his Susanoo took a slight step back.

Kaguya's giant arms struck again, this time with increased force. Shikai used gravitational spheres to try and slow down the attack, but he quickly realized that this strategy was ineffective. Kaguya's claws were far too powerful, slicing through his defenses as if they were nothing.

Then, without warning, Kaguya lifted a massive paw and, with a brutal gesture, brought down a gigantic asteroid from the sky.

"Not bad," murmured Shikai, looking up. But his smile faded as he felt the true weight of the attack. The asteroid crashed into the Susanoo, causing an explosion of energy that finally shattered the dome. The barrier broke apart, releasing a destructive wave of chakra that swept everything in its path.

Shikai reappeared from the debris, his Susanoo now cracked. His right eye, the Tenseigan, shone intensely as he simultaneously activated three stigmata: Yin, Yang, and the Moon.

The entity's wings opened, releasing thousands of gravitational spheres in all directions.

But Kaguya was not impressed. With unexpected speed, she leaped into the air and used her massive claws to slice through the spheres, her chakra surging around her. Every time Shikai tried to immobilize or harm her, she regenerated almost instantly, increasing her power with each passing second.

Kaguya struck again, her colossal arms sweeping across the terrain. Shikai dodged by transforming into a cloud of black butterflies, but even in this form, the giant arms seemed to relentlessly pursue him.

Finally, Kaguya managed to hit him directly. Charred bones erupted from her claws, piercing Shikai from all sides.

"Death is your only option, wretched one!" she declared.

Shikai, impaled by dozens of bones, smiled despite the pain.

"If I hadn't activated the Yang stigma... you would have been right. I would have been dead fifty times over," he admitted.

A golden light emanated from his body, and the wounds caused by the charred bones began to close. But even with the power of Yang, he knew he couldn't continue like this indefinitely.

"It's time to step up my game."

Kaguya furrowed her eyebrows as she sensed a new energy emanating from Shikai.

"What is that...?" she murmured, slightly concerned.

Shikai closed his eyes, and a complex mark appeared on the center of his chest. His chakra changed, becoming darker, denser, and more terrifying.

"The Jūbi stigma," he said calmly, opening his eyes.

His Susanoo, already imposing, seemed to grow even larger. Shadows surrounded its armor, and its wings extended. The spheres of truth began to orbit around him at a blinding speed, slicing through anything they touched.

Kaguya took a step back, her face showing an expression of pure concentration.

The battlefield stretched as far as the eye could see, ravaged by the previous confrontations. The gigantic silhouette of Kaguya in her rabbit form loomed over everything, her multiple arms and two Rinne Sharingan sparkling in each eye, radiating an overwhelming energy. Facing her, Shikai stood tall, calm, his hands forming a complex mudra.
