At this time, Obito's actions should not be interpreted as simple vengeance. His feelings toward Konoha were still deeply conflicted.
On one hand, he was a rogue S-class ninja preparing to spark the Fourth Great Ninja War, all to resurrect Rin and take revenge on the shinobi world. But on the other hand, deep inside, he hoped someone in Konoha would see through his disguise and stop him—perhaps even save him from himself.
This complex psychology was subtly revealed during his confrontation with the Fourth Hokage. The same contradictions echoed now, during the massacre of the Uchiha clan. While Obito had erected a spatial barrier over the surface of the Uchiha district, he had left the sewers weakly sealed—almost intentionally vulnerable.
It was as if he subconsciously wished someone would discover the truth.
The barrier in the sewers could be bypassed by any ninja proficient in sealing or barrier-breaking techniques, though it would take skill and intuition.
Coincidentally, our protagonist Tom happened to be a ninja with the blood of the Uzumaki Clan, naturally sensitive to barrier-type sealing techniques. (Well, excluding Naruto, who has great potential but not much finesse at this age.)
Over the past year, Tom had been studying sealing techniques on his own while sneaking into the library. He had even developed his own sealing scrolls. They were crude—used mostly for storage purposes—and had many limitations. For now, each scroll could only store non-living matter smaller than one cubic meter, and each scroll had just three separate storage spaces.
Still, it was progress.
In the damp, dim sewer, droplets of water echoed as they dripped from the ceiling into shallow puddles.
"It should be here."
Tom, his small figure cloaked in shadow, turned down a narrow corridor in the sewer. Ahead, the air shimmered strangely, like warped glass or thick mist. A faint space distortion.
He formed hand seals quickly, his fingers moving with blinding speed—so fast it seemed like he had four hands at once.
"Seal Technique: Reverse Seal — Hollow Pillar!"
He slammed his palm forward.
The shimmering barrier rippled violently where his hand touched it, and a cylindrical tunnel about a meter in diameter formed in the distortion.
Without hesitation, Tom slipped inside like a cat. Within five seconds, the cylindrical passage vanished as if it had never existed.
He was now inside the underground sector of the Uchiha Police Force.
"If I'm lucky, I might find it... Shisui's Instantaneous Body Flicker Technique."
Tom whispered to himself.
The air was thick with the scent of blood.
Even underground, the coppery tang of blood stung his nose.
He advanced carefully. Corpses of Uchiha police officers were strewn across the corridors. Their bodies were oddly intact—no mess, no chaos—just clean, efficient kills.
"Confinement Room... Rest Area... Meeting Room... Equipment Room... Archive Room..."
He made his way straight to the data archives. Tom opened one of his scrolls and quickly began sealing files and scrolls into it—starting with the highest-ranked materials.
Among them, he found something surprising: files related to Hiruko—an S-rank missing-nin of Konoha.
"This is... information on Hiruko, the defector who attempted the Chimera Technique?"
According to the files, Hiruko was a friend of Jiraiya, Tsunade, and Orochimaru during their time under the Third Hokage. But unlike the legendary Sannin, he had no talent for ninjutsu. A true underachiever.
In order to overcome his lack of talent, Hiruko had developed a forbidden jutsu—Chimera Technique (Guiya Luo)—that could fuse the abilities of other ninja or creatures into his own body, even Kekkei Genkai. But once discovered by Hiruzen Sarutobi, the Third Hokage dispatched the Sannin to eliminate him. Somehow, Hiruko had escaped and vanished.
The files revealed the Chimera Technique was still incomplete, but theoretically powerful enough to change the fate of a ninja with no natural ability.
"Interesting..."
Tom sealed the scroll away.
Next, he found scrolls describing advanced jutsu, including the Shadow Clone Technique—originally developed by the Second Hokage.
Unlike standard clones, Shadow Clones were physical entities that could attack, use jutsu, and interact with the environment. The only drawback was that chakra was evenly divided among all the clones, and they disappeared when hit hard enough.
As he sorted through more scrolls, a loud rumble shook the underground vault. Dust fell from the ceiling.
"There's a battle happening up there."
The vibrations were intense.
Judging by the power of the shockwaves, whoever was fighting on the surface was no ordinary opponent.
"I've got most of what I came for. But let's see what else I can find while the Gate of View (Jingmen) is still active."
Tom's energy from the Sixth Gate wouldn't last long. Half an hour at best.
If he wanted to pick up more "trophies" from the chaos above, now was the time.
Before Root arrived.
If Danzo's men showed up first, they would strip this place clean, and Tom wouldn't even get the scraps.
With that, he darted toward the Police Chief's office.
On the surface, in the central courtyard of the Uchiha district, a fierce battle was underway.
A masked man—his face half-covered, only one eye exposed—was fighting against an Uchiha elite.
"Who are you?! You wield the Mangekyō Sharingan... you must be one of us!" shouted the Uchiha warrior.
Tom recognized the name from memory.
"Uchiha Soratake... the Seventh Elder of the Uchiha Clan."
A veteran known for his mastery in taijutsu and swordplay. His Sharingan had awakened to three tomoe at the age of nine.
The masked man didn't reply emotionally. In a flat tone, he recited Soratake's information as if reading from a file.
"Uchiha Soratake. Age: 49. Specialty: Kenjutsu. Sharingan stage: Three Tomoe. Not a threat."
"Konoha-ryu: Dance of the Three Suns and Moons!"
Soratake blurred forward, his body splitting into three identical afterimages that slashed at the masked man from three angles.
Tom observed closely.
The masked man's right eye spun, transforming into a Mangekyō Sharingan—a swirling pattern indicating a space-time technique.
"Kamui."
Soratake's three clones passed right through him, merging back into one body on the other side. No hit landed.
"A space-based Mangekyō ability... Kamui." Tom whispered from his hidden vantage point.
Soratake staggered back, eyes narrowing.
"You have the Sharingan... and yet you slaughter your own clan? Are you Konoha's dog now?"
He held his sword tightly, the blade trembling slightly as emotion took hold.
The masked man said nothing. His silence was as deadly as his jutsu.
Tom didn't interfere. Not yet. His goal wasn't to play hero or martyr.
It was to gather knowledge, seize power, and survive.
His thoughts turned to the scrolls already sealed in his pouch. Techniques that once belonged to legends... now belonged to him.
A cruel but necessary truth.
As the battle above reached its climax, Tom vanished into the shadows once more, a silent witness to the end of a clan and the beginning of something greater.
