Transmigrated into the body of Uchiha Kagami, an orphan from Konoha, burdened with a disability, he faces an incredibly difficult start. Relying on his forensic mind and scientific methodology, he resolutely embarks on an unprecedented path as a ninja.

He became Orochimaru's apprentice, rising to fame in the Third Shinobi World War and driving change in Konoha.

He eventually became a powerhouse surpassing the Kage level, joining forces with the Fourth Hokage and the Legendary Sannin to completely revolutionize Konoha and lead the ninja world towards an unknown new era.

"Fuck! Damn it!!"

When Bai Yifei woke up, he found an old man spitting on his face.

Just when he wanted to let him see the power of his sandbag-sized fist, he didn't expect a fire dragon to appear next to the old man.

He was to be directly appointed as the Fourth Hokage of Konoha.

With the attitude that he was already here, he decided to make a big splash in the Naruto world...

First of all, my surname is Uchiha. Hmm... and inside my body is a sealed Sukuna.

Not once did I try to reconcile with Sukuna. Once I confirmed he couldn’t break the seal, I began to ruthlessly exploit him.

With my Mangekyō and Domain Expansion unleashed, the strongest Bloodline Elimination in history was born—

—— Slashing Release!

Without the slightest hesitation, knowing that my acting wouldn’t fool the Third Hokage and others, I fully displayed my true Uchiha nature from beginning to end.

There was no betrayal, and absolutely no clan massacre.

We, the Uchiha clan, will rebuild Konoha from the ashes!

(Not having watched Jujutsu Kaisen is fine—this just borrows some character settings, with some creative liberties. But if you haven’t watched Naruto… why are you even here?)

As everyone knows, the mainstream chakra attributes in the ninja world are wind, fire, water, earth, and lightning, with yin and yang being hidden attributes. There are only seven chakra attributes; this is common knowledge in the ninja world. Only a few know that there is an eighth, hidden, special attribute: the space-time attribute. This is a power that even the most overpowered can barely master! Having transmigrated to the Naruto world and entered the same generation as the perfect ninja, Minato Namikaze, Gojo Yoru initially intended to become stronger by any means necessary. However, after a period of palpitations, he discovered that he had refined a special chakra and awakened a space-time bloodline limit. From a hellish start to an incredibly favorable one, Gojo Yoru decided to show this bloodline-obsessed ninja world what it truly means to be a superior ninja.

"Itachi, you are unfilial, disloyal, and unjust. It's not too late to turn back now."

"Obito, go back to Gotham. Batman says he's not going to fight you anymore."

"Danzo, you have abused your power for personal gain, your desires are boundless, and you have committed countless crimes that are unforgivable."

"Hiruzen, you have been too lenient with Danzo. You are unworthy of your position. Considering your past merits, you should step down."

"Tsunade, you don't want Konoha to fall into decline, do you... You're going to be the Hokage!"

"Orochimaru, I'm giving you a chance to start over. Wasn't everything before Danzo's fault?"

Chiya: I've worked so hard for so many years to change the ninja world like this, isn't it all so that I can live a carefree and happy life?

Tsunade, you've really had too much to drink!

Transmigrated into Naruto? Dark turn! Must turn dark! Just wait. I will repay you a hundredfold for everything you've given me! (Dark fantasy, please do not enter if you dislike this genre.)

[Xiao Xuesen]

On a blood-red moonlit night, the internal strife in Konoha ultimately led to the annihilation of the powerful Uchiha clan.

Fortunately, before their clan was wiped out, a soul from another world transmigrated into the body of young Uchiha Tama.

Uchiha Tama played it safe and developed his strength cautiously, surviving until the very end of the Fourth Shinobi World War.

However, Uchiha Tama was quite dissatisfied with Sasuke's compromise and leniency. The death of a few leaders could not extinguish the hatred in Tama's heart!

What is Konoha anyway?

What is Naruto compared to that?

What does a famous name even matter?

What good would it do to unify the ninja world?

No, I, Uchiha Tama, will carry the banner of the clan! I will expand my lineage, have countless descendants, and restore the glory of the Uchiha clan!

I, Uchiha Tama, will surpass my ancestors Indra and Uchiha Madara, leading my clan to the pinnacle of the ninja world!
