A few days after Yugito became a ninja for the Hidden Leaf, Naruto led her into the Hyperbolic Time Chamber, a place where time flowed differently and training could be taken to new extremes.

"Alright, Yugito-chan, remember when I told you I have more transformations?" Naruto said, his eyes sparkling with enthusiasm.

"Yes! Are you going to show me?" she asked, her heart racing with anticipation. She had seen glimpses of Naruto's power, but this felt different—more intimate and personal.

Naruto nodded, stepping back a little to give himself space. "This is called Super Saiyan!" he declared, his voice ringing with excitement. In an instant, his black hair transformed into a brilliant gold, and his eyes shone teal like precious gems.

Yugito gasped, her breath catching in her throat. "I've seen this form before when you fought Cold. It boosts all your attributes evenly, making you faster and stronger, right?" She marveled at the power radiating off him, the air around them shimmering with energy.

"Exactly!" Naruto grinned, the joy of transformation evident in his expression. "But there's more. Check this out!" With a shout, he transformed again. "This is Super Saiyan Ascended, or you can just call it Super Saiyan 2!" His muscles bulged with power, his hair spiking higher, and electricity crackled in his aura like a summer storm.

Yugito's eyes widened as she took in the sight. "It looks similar to the first one," she said, still reeling from the intensity of his energy. "But I can feel the difference—it's… overwhelming!"

"Right?" Naruto chuckled, his confidence soaring. "It might look similar, but it gives me another power boost. My hair gets even spikier, and you can see the lightning in my aura. It also makes me more serious in fights."

"Wow," she whispered, captivated by the transformation. Each form he revealed was a testament to his strength, and she felt a mixture of admiration and awe.

"AND THIS IS TO GO EVEN FURTHER BEYOND!" Naruto shouted, his voice echoing through the chamber as he bent over, summoning all his energy.

The ground trembled beneath them as he unleashed a tremendous surge of power. "Ahhhhhh!" he roared, his body vibrating with intensity. His hair began to lengthen, shimmering in the light, golden strands cascading down his back. With each second, the air around him crackled with energy, creating an electric atmosphere that charged the room.

Yugito watched, her heart pounding in her chest. She could feel the heat radiating from him, and an overwhelming sense of awe washed over her. "Naruto, you're incredible!" she shouted, but her voice barely registered over the roar of his transformation.

"Arghhhhhhh!" Naruto continued, pushing beyond his limits. His muscles swelled, bulging with raw power, and his skin glistened with sweat as he struggled to contain the energy surging through him. Every vein in his body stood out, pulsing with life and intensity.

"Naruto, stop! You'll destroy this place!" Yugito cried, her voice filled with concern. She could see the strain on his face, the determination mixed with an edge of desperation. He was teetering on the brink of something monumental.

"Ahhhhhh!" he roared again, and for a moment, the chamber shook violently. The walls seemed to vibrate in resonance with his power, as if they were alive. The sheer force of his energy sent waves of pressure rippling outward, and Yugito struggled to maintain her footing.

"Naruto, please!" she pleaded, fear creeping into her voice, but he was lost in the moment, consumed by the overwhelming energy he was channeling.

With one final, earth-shattering shout, he finished his transformation. The air around him crackled with a blinding light as he completed the change, standing tall with an aura that seemed to consume everything around him.

Yugito looked up, her jaw dropping in disbelief. Standing before her was a striking figure—a serious-looking Naruto, his hair cascading down to his ankles like a golden waterfall. Lightning crackled around him, illuminating the chamber in flashes of brilliance, and his eyebrows were completely gone, making him look almost otherworldly.

"This is Super Saiyan 3," he said, his voice now deep and resonant, sending a chill down Yugito's spine.

"I… I don't really like this form," she admitted, feeling a strange mix of fear and admiration. The power radiating from him made her feel both small and exhilarated.

"This transformation does give me a significant power boost, but it's exhausting. I can't maintain it for long," Naruto explained, his serious tone cutting through the tension.

"Then why would you ever use it?" she asked, genuinely puzzled, her brows furrowing.

"Because it still enhances my strength! But hold on, there's one more transformation!" He powered down to his base form, a sudden shift that felt almost jarring after the intensity of his Super Saiyan 3 form.

"Why go back to your base form if there's one more?" she questioned, tilting her head in confusion.

"Because I don't need Super Saiyan 3 for this next one," he replied, a mischievous glint in his eye. He began to power up again, the air around him crackling with anticipation.

"Ahhhhhh!" he shouted, channeling his energy once more.

"Not this again!" Yugito exclaimed, a mix of dread and excitement bubbling inside her as she watched Naruto begin his final transformation.

To her astonishment, dark pink fur erupted across his upper body, transforming his appearance completely. His black hair grew once more, but this time it stopped shorter than his Super Saiyan 3 form. As he completed the transformation, Naruto stood before her, an impressive figure shrouded in dark pink fur, his serious expression commanding respect.

"This is Super Saiyan 4," he explained, his voice deeper than before, resonating with power. "To achieve this form, a Saiyan needs to first transform into a Great Ape under the light of a full moon. If they manage to control that primal form, they can then refine their energy and revert back to a humanoid state while maintaining the power of the Great Ape."

"Interesting. So it's a mastery of that raw power," Yugito said, her eyes widening. "And you can keep your mind while in this form?"

"Exactly! With training and focus, I can harness that power while still thinking clearly. It's a significant boost, but also requires a lot of discipline," Naruto clarified, his eyes shining with a fierce determination.

"Real men wear pink," she laughed, the tension breaking as they shared a moment of levity.

OMAKE

Naruto shows Yugito his transformations.

"Guess you can say that! Sasuke's form is dark red, and he's definitely not a real man," Naruto replied, smirking back at her.

"I see why you brought me here. Outside, the whole Earth would shake from Super Saiyan 3," she said, shaking her head in disbelief, still processing what she had witnessed.

"But if I could do this all along, why not use it to finish fights quickly?" She asked aloud, his brow furrowing.

"Where's the fun in that? If my opponents can't push me to transform, why should I overkill them? It would be boring," he explained as they walked out of the chamber, their laughter echoing around them.

As they stepped back into the normal world, Yugito felt a new sense of camaraderie with Naruto. She had glimpsed not just his strength but the heart behind it.
