Sasuke, already eager to give it a try, quickly asked, "What prerequisite?"
After hesitating slightly, the Nine-Tails said, "Beast's Calamity alone probably won't be enough. We must incorporate natural energy and apply Senjutsu as well. Only then will we stand a chance!"
Ordinary ninjutsu could not even get past the Truth-Seeking Orbs.
Although Beast's Calamity was a fusion of a complete-body Susanoo and the complete Nine-Tails, a forbidden technique within the Ninja World, it still had not escaped the scope of ordinary ninjutsu.
Since Sasuke and Naruto, the casters, did not possess the power of the Six Paths, they had to incorporate a massive amount of natural energy. Using Senjutsu, which the Truth-Seeking Orbs could not dissolve, as their foundation, they would attempt to break through the Truth-Seeking Orbs' defenses.
Moreover, if they did not activate Senjutsu, neither Sasuke nor Naruto had the ability to detect Obito's Limbo Clones. When the time came, even if they unleashed Beast's Calamity, they would still be sitting ducks before Obito's Limbo Clones.
Sasuke said dismissively, "Doesn't Naruto know Senjutsu? What's so difficult about that?"
Before the Nine-Tails could answer, Naruto shook his head and said glumly, "When I enter Sage Mode, I can't activate Kurama Mode. And once I use Kurama Mode, I can't enter Sage Mode!"
Without a doubt, Naruto still could not fully fuse senjutsu chakra with Nine-Tails chakra. He could not make Sage Mode and Kurama Mode compatible and activate Kurama Sage Mode—in other words, Sage Fox Mode.
Kakashi's expression darkened. He had actually anticipated this long ago, because Naruto had never used Sage Mode and Nine-Tails Chakra Mode at the same time before.
After thinking back briefly, Sasuke understood as well.
The Nine-Tails said then, "If you can't do this, even if you join forces and use Beast's Calamity,
