Legacy Reborn (Sasuke x RWBY Sequel)

2 - Reborn

It's been five years since Madara Uchiha was reborn into the world of Remnant.

Now, as Katsuro Rose, he found himself in a life he never imagined. From the moment he could walk, he had always been a quiet child, keeping mostly to himself. He spent hours in silence, often retreating to the small room he shared with his older sister.

Her older sister's name is Sarada Rose, two years older than him.

While she would play or sleep, he would sit by the window, staring out at the world he barely understood, and in the quiet moments, he'd absorb everything.

The books became his greatest companions. He poured over the history of Remnant—of its kingdoms, the Grimm, the Hunters, and Huntresses.

Katsuro had learned to read at a young age, much faster than his parents expected, and now, at five years old, he was already fluent.

He had recently taught himself to speak English, the common language of Remnant, though he still practiced the nuances daily, determined to master it just as he had mastered his own tongue in his past life.

Still, his mind would drift back to that life—to the great battles, to the power he once held as Madara Uchiha, a name that felt both distant and close.

But here,

in this world,

he was different.

Here, he was Katsuro, the second child of Weiss and Sasuke Rose, a family respected and revered in this world.

His father, a Huntsman, and his mother, a noblewoman of great skill, were both formidable warriors. And yet, there was something else about them—something that reminded him of the shinobi world he had left behind.

It was during one time when he was a baby, his father held him for the first time, that Katsuro—Madara— felt his past collide with his present.

In front of him is a man who was unmistakably his father—Sasuke Rose. But what caught Katsuro's attention wasn't just his father's familiar face.

It was his eye.

Those same, unmistakable Rinnegan, stared back at him years ago when he was a baby.

He remembered it.

He remembered them from the Fourth Great Shinobi War, back in the Elemental Nations, where Sasuke Uchiha had fought alongside Naruto Uzumaki to bring peace.

It sent a shiver down his spine.

The memories flooded back—Madara's plans, the conflict, the way his own ambition had driven him toward godhood. And now here he was, reborn into a world with little chakra, no Sharingan, and definitely no powers to speak of.

At least, not yet.

His body was that of a child, but his mind was still the same. The once-mighty Uchiha had become a boy, locked in a new world's cycle of life. But the Rinnegan... it was here. And if the Rinnegan existed, then perhaps the powers he once knew weren't gone forever.

His father—Sasuke—was not the same man who had fought him during the war.

At least that's what he thought.

The probability of him being the son of whom he fought in the war is astronomically close to never, but it was a possibility.

And in truth, it is the same Sasuke he fought back then.

Yet, to Madara, the similarities between this Sasuke and the one from his world were undeniable.

Katsuro couldn't yet fathom why or how such a convergence of worlds had happened.
