There was actually a second Ten-Tails in the Shinobi World!
Zou Hyuga refused to believe it at first, but after sensing the chakra emanating from the Ten-Tails, he accepted the fact.
Kaguya had possessed a Ten-Tails and swallowed a Chakra Fruit to become the "immortal and indestructible" Progenitor of chakra. It stood to reason that Jigen, a fellow Starry Sky Otsutsuki, would possess one as well.
Perhaps creating the Ten-Tails and the God Tree was already a well-established technology among the Starry Sky Otsutsuki.
Yet there was still something he did not understand. If Jigen possessed a Ten-Tails, why had he not quietly gathered the Shinobi World's natural energy over all those years? Why had he chosen Zou instead and planted Karma on him?
Gathering natural energy should hardly have been difficult for an Otsutsuki.

"Rest assured, the Shinobi World has enough chakra to support several Ten-Tails Jinchuriki."
Zou Hyuga remained noncommittal and slowly approached the Miniature Ten-Tails. Seemingly sensing his approach, the Miniature Ten-Tails began to stir, threatening
