After returning to the Flying Fortress, Shinji immediately set it flying west, toward the Land of Demons.
To become the Ten-Tails Jinchuriki, he needed a place where he wouldn't be disturbed. The fake "Itachi Uchiha" projected by the Overlord was currently near the Land of Hot Water in the eastern Shinobi World, so Shinji headed west, to the Land of Demons on the other side of the world, to become the Ten-Tails Jinchuriki.
In any case, it was never wrong to assume the Overlord was as powerful as possible.
As Shinji's strength grew, so did his perspective and understanding. He was increasingly certain that the Overlord, who had devoured one world after another, was far more powerful than Kaguya Otsutsuki, the Chakra Ancestor.
Or, at the very least, the Overlord had surpassed the ordinary members of the Otsutsuki Clan.
The Otsutsuki Clan had to plant a Divine Tree to plunder a planet's energy, then spend a great deal of time guarding it as it slowly drained the planet, matured, and bore fruit.
But once the Overlord set its sights on a world, that world quickly began its countdown, until the Overlord devoured it without a trace.
One method slowly drained a world through a Divine Tree. The other devoured it outright.
The difference was obvious.
Still, caution aside, they had the Ten-Tails now, so there was no need to keep secrets from his own people. Shinji summoned all his subordinates to the fortress's conference hall.
Once everyone was seated, Shinji removed the Cat Mask. "Some of you already know who I am. Others may still be unsure. I'll be open with you now and tell you why I secretly formed the Akatsuki Organization."
No one in the conference room was surprised when Shinji took off his mask.
