Late at night, in the Uchiha Clan Compound.
Eight-year-old Sahiro Uchiha was jolted awake by a bone-chilling cold.
He had been a corporate drone on twenty-first-century Earth, transported to this Naruto world after dying suddenly from overwork.
He had inherited the original owner's memories, as well as his body.
But now was no time to dwell on that.
Screams rang out outside.
Firelight stained the paper windows red.
The smell of blood filled the air.
The Uchiha Clan Downfall?!!!
Sahiro Uchiha's heart sank.
He remembered this part of the story.
With the help of the Masked Man, Obito Uchiha, Uchiha Itachi had slaughtered the entire Uchiha Clan in a single night, leaving only Sasuke alive.
And he, Sahiro Uchiha, was someone who hadn't even existed in the original story.
Sasuke's twin older brother!
He looked almost exactly like Sasuke.
Although he was Itachi's younger brother, he didn't dare bet that Itachi would never kill him. What if he did?
"Fuck! I'm screwed!"
That man was here! Uchiha Itachi! He was here!
He stared at his parents lying in pools of blood, then at Itachi slowly approaching with a sword in hand.
A chill shot straight to his head!
He was going to die!
"Don't kill me! Brother! I'm your own little brother!!!"
"My foolish little brother, you've finally started begging for mercy. Are you ready to meet your death?"
[Ding! Emotional fluctuations detected in the host! Bond Simulator System activating... activation successful!] [Host detected to be in mortal danger. System unlocked ahead of schedule.] [Available link targets within scanning range:] Uchiha Itachi (biological brother) bond strength: ★★★★★ Uchiha Fugaku (father) (deceased) bond strength: ★★★★☆ Uchiha Mikoto (mother) (deceased) bond strength: ★★★★☆ ??? (identity unknown, wearing a mask) bond strength: ???
Four options appeared before his eyes.
The one wearing a mask.
He knew who that was.
Obito Uchiha.
The mastermind behind the Akatsuki, a Space-Time Ninjutsu user who possessed the Kamui Dimension, and one of the perpetrators who had orchestrated the Uchiha Clan Massacre.
As long as he could obtain Kamui Intangibility, he would have a guaranteed means of escape.
He selected the fourth option.
[Link target: ???] [Linking... target's true name detected: Obito Uchiha.] [Link successful!] [Congratulations, host. Ability acquired: Kamui Dimension: Basic Control.] [Description: You have obtained basic access to the Kamui Dimension. More abilities can be unlocked as your bond level increases.] [Remaining links: 0]
"System, what can you do?"
[Host, this system can link you to any ninja and establish a bond with them. As that bond levels up, you can obtain different rewards.] [At bond level five, you can obtain a special bond reward, as well as a bond projection to assist you in battle.]
A strange spatial power surged into Zuo Hao's body.
[Kamui Dimension: Basic Control] [Ability one: Freely enter and exit the Kamui Dimension (activation time: 0.5 seconds) (not Obito's Kamui Dimension).] [Ability two: Intangibility (duration depends on chakra usage).]
He watched Itachi slowly approach him.
Without hesitation, Zuo Hao turned into a vortex and vanished on the spot.
Meanwhile, on the outskirts of the Uchiha Clan Compound.
The man wearing an orange Spiral Mask, Obito Uchiha, stood on a rooftop, coldly watching the burning Clan District below.
His task was to cooperate with Itachi, eliminate all resistance, and ensure the Uchiha Clan's complete destruction.
Everything was going according to plan.
Until a hand landed on his shoulder.
"Hi."
Obito's pupil contracted. He whipped around to find an eight-year-old boy standing behind him, smiling at him.
Those eyes reflected the pattern he knew better than any other.
Kamui.
"You..." For the first time, Obito's voice wavered. "How could you..."
"Thanks for the cheat." Zuo Hao raised his hand, ripples of spatial distortion appearing in his palm. "Now it's your turn."
A gateway to the Kamui Dimension opened beneath their feet. Before Obito could react, both of them fell into that gray-white world of cubes.
The moment he landed, Obito put distance between them, staring fixedly at the eight-year-old brat before him.
"Impossible... how do you have Kamui?"
"Take a guess." Sahiro Uchiha tilted his head. "But I can tell you one thing. From now on, I can see every trump card you have."
The Masked Man, Obito, abruptly extended his senses. Space twisted around him, his Sharingan contracted sharply, and for the first time, disbelief and horror crept into his voice.
"No... this isn't my Kamui Dimension! This presence, this structure... this is your Kamui Dimension?!"
"Correct. Too bad... there's no prize."
Zuo Hao tossed out those words casually, then turned to leave.
"Stop!" The Masked Man's voice suddenly rose, filled with the anger of being toyed with and profound apprehension. "Sahiro Uchiha... Sasuke's twin older brother! You—how exactly did you get the Kamui Dimension?! Why do you have the same ability as me?!"
Zuo Hao paused and turned his head slightly, revealing half of a young face that was eerily calm.
"Do you think I'd tell you? Just as you'd never willingly admit that you're Obito Uchiha."
The name "Obito" struck the Masked Man's ears like a thunderclap.
His entire body jolted, and the pupil behind his mask contracted sharply. His whole presence turned savage and fearful.
"You... you little brat! You know things you shouldn't. Then you're staying here forever!"
Murderous intent swept toward him, almost tangible.
Zuo Hao didn't even blink. Instead, he slowly turned around, wearing an innocent expression that begged to be punched. "Heh. What's so impressive about bullying an eight-year-old kid? If you're really that capable, why don't you go pick a fight with Madara Uchiha?"
If hearing the name "Obito" had shaken him, then "Madara Uchiha" had ripped open the scar he had desperately tried to conceal in the deepest part of his soul.
Obito froze in place, even his breathing stopping for a moment. His voice became almost hoarse with disbelief. "You... who exactly are you?!"
As though the murderous tension from a moment ago had never existed, Zuo Hao slipped his hands into his pockets and delivered the most earth-shattering words with the most innocent smile.
"Hehe, Obito, don't be so nervous. I know what you're planning. It's just the Eye of the Moon Plan, right? Honestly, I'm pretty interested in it too."
He leaned half a step closer, as though sharing a brilliant prank.
"How about... you let me join in?"
Insane.
Either this kid or this world had to be insane.
Obito's thoughts were thrown into utter chaos.
"You... you bastard! Who exactly are you?"
"Me?" Zuo Hao pointed at himself, his smile growing even brighter. "Someone who wants to have a little fun in this boring world."
Obito stared fixedly at the eight-year-old child before him.
There was no fear in those eyes, no reverence, not even the slightest grief over the tragedy of the Uchiha Clan Downfall.
All they held was a certain... unnerving confidence.
As though he had already seen the future.
"You know about the Eye of the Moon Plan?" Obito asked in a low voice.
"Infinite Tsukuyomi." Zuo Hao nodded. "Using the moon to cast the ultimate genjutsu, immersing all of humanity in beautiful dreams. A pretty romantic idea, though the execution is a little heavy-handed."
"What do you want?"
"I already told you." Zuo Hao spread his hands. "To join you."
"Impossible." Obito refused almost instinctively. "You're an eight-year-old brat. What makes you think you're qualified?!!!"
