After hearing about the little Ten-Tails, Obito's expression shifted repeatedly.
Although he had reclaimed his Sharingan, and it had evolved from the Mangekyō Sharingan into the Eternal Mangekyo Sharingan, he knew that even with a pair of Eternal Mangekyo Sharingan, the gap between him and Shinji would be hard to close.
Even if he advanced another step and evolved his Eternal Mangekyo Sharingan into the Rinnegan, at best he would be like Nagato during the Fourth Shinobi World War. He still wouldn't be a match for Shinji.
But the information White Zetsu brought about the little Ten-Tails made his heart race!
He understood better than anyone what the Ten-Tails meant. Otherwise, Shinji and Ōtsutsuki Isshiki wouldn't have fought so desperately over it.
If he could seize the little Ten-Tails, he could stand shoulder to shoulder with Shinji and become a Ten-Tails Jinchuriki himself.
Then he would have the confidence to stand before Shinji, that young Uchiha, once more.
Obito went from calm to agitated, then back to calm again in a matter of moments. He turned and asked White Zetsu, "Do you know where Ōtsutsuki Isshiki's Ten-Tails is?"
"I heard Group 1 is studying the Ten-Tails. They should know where it's being held," White Zetsu said.
"Group 1."
Obito nodded to himself.
From researchers' casual conversations, he knew that Shinji had gathered nearly all of the Shinobi World's scientific talent and resources to tackle research into the Ten-Tails, the Rinnegan, cells, and many other topics. It made sense that one team would be devoted to studying the little Ten-Tails.
White Zetsu advised him, "We didn't just escape—we also took the experimental materials from Group 3. The Research Institute must be in an uproar by now! We should lie low for a while and deal with the Ten-Tails later."
"Mm!"
Obito
