Naruto: Spiral Into The Darkness

Killer Bee's attempt to dodge the Rasenshuriken proved futile, and the attack struck him with immense force. As the chakra dissipated, Killer Bee's body began to undergo a dramatic transformation. Tentacles burst forth from his back, and his body began to morph into that of a massive octopus.

The Eight-Tails, Eighto, had been unleashed. Its voice boomed in Killer Bee's mind, "Bee, what's up with you releasing me at such an opportune time?"

Killer Bee's response came in the form of a rap, his demeanor now more serious and slightly playful, a sign that the battle was about to escalate:

"Yo, Eighto, my beast, my friend

We're in this together, till the very end

I released you now, 'cause the time's right

We'll take down these foes, with all our might"

Naruto's eyes widened in awe as he beheld the Eight-Tails' true form. He stumbled backward, gasping for breath, still reeling from the exhaustion of using the Rasenshuriken.

Kisame's eyes gleamed with excitement as he observed Naruto's state. "Well, now things have heated up for sure. Looking at your state, fox boy, it seems like that Jutsu of yours takes too much of your chakra. Judging from your state, you can't do another unless you undergo that transformation again."

Naruto's inner turmoil boiled over, his determination and pride driving him to push beyond his limits. "Damnit, I won't lose here! I won't let Kisame take all the glory! I have to prove just how powerful I am! I have to become stronger, otherwise...!"

Kisame's grin widened as he began to weave intricate hand signs. "Fox Boy, watch closely, a master at work!"

With a flourish, Kisame completed the seals, unleashing a mighty roar: "Water Style: 1000 Shark Bombs Jutsu!"

A thousand shark bombs shot up from the waterfall, each one aimed at Killer Bee, now in full Eight-Tails transformation. The shark bombs exploded in a cacophony of sound and fury, but Killer Bee was unfazed.

Using his tentacles to parry the attacks, Killer Bee charged up a massive, glowing sphere of chakra – a Tailed Beast Bomb. The sphere pulsed with energy, its surface rippling like the ocean's waves. As it grew in size, the air around it began to distort, the very fabric of reality seeming to bend under its immense power.

The Tailed Beast Bomb was a legendary technique, capable of leveling mountains and shattering the earth. Its sheer destructive potential hung in the balance, as Killer Bee prepared to unleash it upon his foes.

Kisame's eyes widened in alarm as he beheld the Tailed Beast Bomb. Its sheer scale and energy output made his own Shark Bombs seem like mere fireworks in comparison.

Killer Bee hurled the Tailed Beast Bomb towards Kisame with a mighty roar. The sphere of chakra shot forward, its trajectory unwavering as it bore down on its target.

Naruto, still reeling from his exhaustion, watched in a mixture of awe and despair. He was unsure of what to do, his mind racing with the implications of Killer Bee's attack.

Kisame, with his incredible speed and agility, attempted to dodge the Tailed Beast Bomb. However, the attack's sheer size and energy output made it nearly impossible to avoid.

The Tailed Beast Bomb engulfed Kisame, its blast wave ripping through the valley with incredible force. The sound of the explosion was deafening, the shockwave sending Naruto stumbling backward.

As the dust settled, Naruto's eyes widened in shock and frustration. "Damnit, why? Why am I still weak?" he exclaimed, his fists clenched in anger and disappointment.

Kisame's fate hung in the balance, the outcome of the attack uncertain. Had he survived the Tailed Beast Bomb, or had he fallen victim to its devastating power? The silence that followed was oppressive, punctuated only by the sound of Naruto's ragged breathing and the distant rumble of the waterfall.

As the blast area cleared, Kisame's robe was torn to shreds, and he was bleeding from numerous scratches and gashes. However, his body had begun to merge with Samehada, the sword's energy coursing through his veins.

The merger allowed Kisame to withstand the devastating effects of the Tailed Beast Bomb. Samehada's sentience and quick reaction had enabled it to absorb and redirect some of the blast's energy, while Kisame's own cunning and battle experience had helped him to mitigate the damage.

Kisame's voice was laced with a mixture of respect and admiration as he spoke, "Didn't expect anything less from the Eight-Tails. I barely survived that... only due to Samehada's quick reaction and my own quick thinking."

As Kisame finished speaking, his body began to undergo a grotesque transformation. His limbs stretched and merged with Samehada, his skin turning a dark, shark-like gray. His face elongated into a shark's snout, complete with razor-sharp teeth.

Killer Bee and Naruto watched in horror as Kisame's transformation into a humanoid shark-like creature was completed. The air around him seemed to ripple with malevolent energy, as if the very fabric of reality was warped by his presence.

Kisame's hands quickly flashed through a series of intricate signs, his voice booming as he unleashed the Waterfall jutsu. The nearby waterfall, once a serene and tranquil sight, transformed into a raging torrent as the water was released in a single, mighty burst.

The sound of rushing water filled the air, a deafening roar that threatened to consume everything in its path. Naruto's eyes widened as the water surged forward, forming a massive dam that threatened to engulf the entire area.

"He's strong," Naruto muttered to himself, his voice barely audible over the din of the water. "Why can't I be like that? Damnit, I need to figure out a way to use the Nine-Tails' power. I know they said they would teach me, but it's crucial I undergo the transformation now or we'll never defeat the Eight-Tails."

As Naruto struggled to come to terms with his own limitations, Kisame smiled grimly at the Eight-Tails. His eyes gleamed with a fierce light, his confidence in his own abilities evident in every line of his body.

Killer Bee, sensing the shift in the battle's dynamics, began to rap in a low, urgent tone. "Yo, Eighto, my man, it's time to prepare

For the unknown, for the battle that's there

We gotta be ready, gotta be strong

Gotta take down this shark-like creature, all day long."

The Eight-Tails, Eighto, responded in a voice that echoed in Killer Bee's mind. "I'm ready, Bee, let's do this thing

We'll take down monster, make his heart sing

A song of defeat, of pain and of woe

We'll show him the power of the Eight-Tails, don't you know.
