After the great war, the Shinobi World finally grew peaceful.
Through the efforts of Uchiha Yū and the others in Kusagakure, the remaining threats were completely eliminated as well.
Madara Uchiha was dead, too.
Three days later.
Uchiha Sora gathered his subordinates in the Leader's Mansion in Kusagakure.
"Now that the greatest crisis is over, I'll leave the postwar matters to you. I need to go away for a while," he told them.
"Yes!" Uchiha Yū, Zabuza, and the others answered respectfully.
By now, Uchiha Sora's strength had long since become the stuff of legend in their minds. He stood as tall as a god in their eyes.
Everyone looked at him with reverence.
Uchiha Sora smiled, then vanished in a flash.
He intended to search for Isshiki in secret. It might not be easy, but the matter had to be resolved eventually. The sooner he found Isshiki, the sooner he could eliminate the threat.
Before that, however, he had something else very important to do.
He had to revive Shisui.
Before the great war, when he had yet to awaken the Rinnegan, he would not have had the means to do so.
But now that Uchiha Sora possessed the Rinnegan, he could naturally use Rinne Rebirth.
And reviving Shisui had always been something Uchiha Sora wanted to do.
Rinne Rebirth was the Rinnegan's ultimate resurrection technique, capable of reviving someone without a vessel.
It was just like when Obito had revived Madara Uchiha before dying.
Uchiha Sora activated his Rinnegan and immediately unleashed its power.
Powerful ocular energy spread outward, stirring strange ripples in the air.
A moment later, a faint spectral figure was summoned within the space before him.
The spectral figure slowly grew more solid, appearing before Uchiha Sora.
Who else could it have been but Shisui?
