After Obito Uchiha became the Ten-Tails Jinchuriki, he could completely ignore the damage from all kinds of Ninjutsu, but he was not immune to Senjutsu.
For the Allied Shinobi Forces, this was naturally the best possible news.
However, only a small number of ninja in the entire Shinobi World had mastered Senjutsu.
Strictly speaking, the ninja who could use Senjutsu could be counted on one hand.
More troublingly, even mastering Senjutsu did not necessarily mean they could pose a threat to Obito.
After all, becoming the Ten-Tails Jinchuriki had drastically improved every aspect of Obito's capabilities.
Even if Senjutsu could hurt him, the crucial question was how to get close to him and land an attack.
In the earlier battle, one way Naruto and the others had managed to attack Obito was through Tobirama Senju and Minato Namikaze using the Flying Thunder God Technique to bring them within striking distance in an instant.
The other was to unleash attacks over such a wide area that Obito could not dodge.
Aside from those methods, Naruto and the others found it extremely difficult even to approach Obito.
Such was the power of the Ten-Tails Jinchuriki.
But now, with Naraku's reminder that Taijutsu could also threaten Obito, the two clearly had new ideas.
"While this is good news, don't get too excited."
"With Obito's current strength, an ordinary ninja's Taijutsu is like child's play to him. It can't hurt him at all."
"Besides, you've fought him yourselves. You know how absurdly fast he is. Ordinary ninja basically can't keep up with him."
Minato nodded at that. He and the Second Hokage Tobirama Senju were probably the ones who understood best just how absurd Obito's current speed was.
Without the Flying Thunder God Technique, whether they could have hurt Obito in the earlier battle
