"I already told you, I'm just a tourist here to sightsee. Why did you have to pick a fight?" Son Goku looked genuinely annoyed, cracking his knuckles as if itching for a proper brawl.
Suddenly, a dark, swirling vortex materialized in front of Itachi, and a figure wearing an orange, spiral-patterned mask stepped out. "Itachi, it's time to go. Konoha's leadership is already mobilizing." As he spoke, the masked man's single visible eye fixed warily on Goku. An instinctual alarm bell rang in his mind—this stranger radiated a palpable, dangerous aura he hadn't anticipated.
Itachi shot a final, conflicted glance at Goku before giving a curt nod. The masked man turned his indifferent gaze back to the Saiyan. "I don't know who you are, but you've certainly drawn my attention. I didn't expect a powerhouse of your caliber to exist in this world. However, this is neither the time nor place for a conversation. I'm certain our paths will cross again."
"Who do you think you're talking down to?" In a blur of motion, Goku appeared directly in front of the masked man. His hand shot out, closing around the man's throat and lifting him effortlessly off the ground. "Listen here, watch your tone with me, or I might just decide to end you right here." Truthfully, Goku had recognized the man the moment he appeared—the so-called final boss. And what's more fun than giving the boss a little lesson in humility?
"Y-You... just who are you?!" The masked man, Tobi, was genuinely shocked. He hadn't even perceived the movement. Before he could activate his Space-Time Ninjutsu—or even process the threat—he was already immobilized.
With a dismissive flick of his wrist, Goku hurled Tobi aside like a piece of rubbish. "Scram, you small fry. Don't get in the way of my sightseeing."
Tobi seethed with humiliation, but a deep, primal caution held him back. This man's power was an unknown variable, and recklessness here could be fatal. Itachi, his brow furrowed, kept his Mangekyō Sharingan fixed on Goku. "What is your true purpose here?"
"Tch! What I do is none of your business—quit interfering!" Goku snapped. His figure vanished again, reappearing beside Itachi. He snatched the Uchiha's ankle and, with a mighty heave, sent him spinning through the air like a discus until he vanished over the distant treeline.
"You're next!" Goku turned back to Tobi, who was just staggering to his feet. In an instant, Goku had him by the collar. With a grunt of effort, he launched the masked man skyward in a high arc, sending him following Itachi's trajectory out of the Land of Fire. Whether they'd survive the "trip" was now their own problem.
"Finally, some peace and quiet. Now for my actual business." Having casually dispatched two of the world's major players, Goku was in high spirits. He whistled a tune as he strode toward the main house. Passing the entrance, he noticed the small, unconscious form of Sasuke. He gave the boy's side a light, almost playful nudge with his foot. "Well, since your parents are gone, I'll go easy on you." The irony of the statement—kicking someone and calling it 'going easy'—was lost on him.
Stepping over the young Uchiha heir, he entered the home. His gaze fell upon the bodies of Uchiha Fugaku and Uchiha Mikoto. With a sigh, he gently nudged Fugaku aside with his foot and knelt beside Mikoto. "What a waste... a truly beautiful woman. Pity I was a few minutes too late. But even ashes can be remade." With a thought, he stored Mikoto's form within his World Ring.
He glanced back at Fugaku's body. "To have fathered sons like Itachi and Sasuke, your bloodline must hold some merit. I'll borrow your eyes as a keepsake." A precise tap of ki to the chest caused the eyeballs to dislodge neatly. Goku caught them and stored the prized Mangekyō Sharingan away as well.
Surveying the other fallen clansmen, Goku briefly considered harvesting more Sharingan for the women in his care but quickly dismissed the idea. My ladies shouldn't wear the eyes of the dead. Besides, their natural beauty is perfection. There are countless other ways to empower them.
His search of the compound yielded a few Ninjutsu scrolls from a study. Just as he tucked them away, he sensed multiple presences converging rapidly—Konoha's ANBU and elders were almost upon the compound. With a smirk, he focused his energy and vanished with Instant Transmission.

He reappeared beside a pristine, babbling forest stream. With a sweep of his arm, the women from his World Ring materialized around him, blinking in the dappled sunlight.
"Goku, have we... really arrived in another world?" Saeko asked, her eyes wide as she took in the unfamiliar, lush surroundings.
"Yep," Goku confirmed with a grin. "This world runs on something called Ninjutsu. I snagged a few training scrolls. If you're interested, you can give them a look!" He produced the main scroll and unfurled it on a flat rock.
"Ninjutsu? I want to see!" Rei's eyes sparkled with excitement. The others crowded around, their innate cultural familiarity with the concept piquing their curiosity.
The scroll was detailed, covering chakra theory, basic refinement methods, and several foundational techniques. However, it lacked the specific, high-level jutsu Goku was most interested in.
"Looks like I'll need to have a little chat with the Sandaime Hokage sometime soon," Goku muttered, rubbing his chin thoughtfully. He then turned his attention to the chakra refinement method. For someone of his monumental power, it was child's play. His body was a reservoir of immense ki. By simply willing a fraction of his spiritual energy to merge with his physical energy within that ki, he catalyzed a transformation.
In less than half an hour, a new, vast ocean of chakra coalesced within him, seamlessly integrated with his existing power.
"Right, let's try this out!" Goku focused, forming the ram, serpent, and boar seals with practiced ease—he'd memorized them instantly. "Katon: Gōkakyū no Jutsu!"
A colossal sphere of roaring flame erupted from his mouth, hurtling across the stream and impacting the dense forest on the opposite bank. The resulting explosion was deafening. A pillar of fire and smoke billowed into the sky, instantly igniting the surrounding trees in a raging inferno.
The women stared, jaws agape, at the suddenly blazing forest.
"Whoa! That's incredible!" Yuriko exclaimed.
Goku, however, looked at the spreading conflagration with an expression of genuine, innocent surprise. He scratched the back of his head sheepishly. "Uh... oops? I swear I only used a tiny, tiny bit of chakra... I didn't mean to set the whole forest on fire!"
