Naruto: Reborn, I Lead My Clan to Rule the Ninja World

A blurb by an author who is terrible at writing blurbs:

Sasuke and Madara are both reborn and transmigrate. Naruto will show up midway through. Some settings and plot points are borrowed from Boruto. Later on, it might turn into an interstellar war story (?), with the heroes beating up the Otsutsuki and conquering the universe (?).

There might be a guest appearance midway through by Aizen from Bleach, and the Zoldycks from Hunter x Hunter might make a friendly cameo.

Everything went wrong starting on the night of the Uchiha massacre. The wheel of fate veered out of control, heading in the exact opposite direction.

Little Sasuke uses the power of reincarnation to lead his clan to the front lines of the struggle.

The two-faced spy Uchiha Itachi starts questioning his own life: Is this really his sweet, adorable, innocent, pure little brother Sasuke?

Uchiha Obito is completely stunned. The light he lost has returned overnight, and it turns out everything was just an illusion!

Madara is torn up inside: Should he conquer the shinobi world first, or accept Senju Hashirama's advances first (?)?

Naruto wakes up one day to find the whole world turned upside down: The shinobi world now bears the Uchiha name, and the great nations are all its vassals. Most shocking of all, Senju Hashirama and Uchiha Madara are a couple! Sasuke is no longer as cold and silent as before, and he starts being direct with Naruto!?

But you were the one who friend-zoned me first!

Senju Tobirama is perpetually exhausted: How can he stop his big brother from throwing himself into the wolf's den?

Uchiha Izuna is perpetually heartbroken: His perfect big brother has revealed one fatal flaw: his taste in men!

Ships: SasuNaru, MadaHashiMada (probably switches), TobiIzu (probably switches), ObitoKakashi, ShisuiItachi

The story focuses on their ambitions, with romance developing along the way.

I've dug another hole... I hope I get time to fill it...

The detailed plot is still being imagined, so it might differ a little from the blurb... I never outline my stories. I just go wherever my imagination takes me...

There might be a Hunter x Hunter or Bleach crossover midway through... Still undecided.

OOC warning: Since Sasuke transmigrates from a relatively late point in time, he has more experiences under his belt. Includes character death. If that's not your thing, please just click away using the top-right corner. Thanks.

Theme: After being reborn, Sasuke and Madara lead their clan to dominate the shinobi world.
