Naruto : Cruel Rebirth

Post-Hokage Era, with the full-scale invasion of the Ōtsutsuki clan, the ninja world collapses.
Uzumaki Naruto’s close friends, wife, children, and companions all die in battle one after another...
On the brink of death, Naruto uses the Otsutsuki’s time-based artifact, the “Karasuki,” to send his soul back to the past, reborn as a teenager once more!
Standing before Naruto is Nagato, on the verge of death after using the Rebirth of the Six Paths technique!
For the future of the ninja world, Naruto inherits Nagato’s Rinnegan and begins a drastically different path to power than his previous life.
“That naïve and carefree Naruto Uzumaki, who could only spout ideals, has long since died... on the day his country and family were destroyed!”
— The era of ninjas has not ended!
