It wasn't just Hiruzen Sarutobi who sensed Shukaku and Kurama's presence.
At the Root base, Danzo sensed Shukaku and Kurama's presence the instant it appeared as well. He had been studying the corpse Orochimaru had left behind, but immediately set down what he was doing after sensing them.
The image of that young boy who looked far older than his age surfaced in his mind. Danzo's expression darkened unpredictably. He had no idea what was happening for the moment, and Kurama's sudden appearance made him assume the Jinchuriki had lost control.
The moment he left the laboratory, Danzo rushed alone toward the Hokage's office.
"Bang..."
He forcefully shoved open the office door. Hiruzen Sarutobi shot him an annoyed glance, but Danzo paid it no mind. He walked straight to Hiruzen's side, his eyes fixed on the scene within the crystal ball.
"Not out of control? This is..." The moment Danzo saw the scene in the crystal ball, he was stunned. Naruto stood beside Kurama, equally twenty meters tall, and no matter how he looked at it, it did not resemble a Jinchuriki's relationship with a Tailed Beast.
When a Jinchuriki used a Tailed Beast's power, they did not take this form at all.
That left only one conclusion: Naruto had a way to separate from the Tailed Beast while still preserving its independence.
"This brat really doesn't seem like a ninja at all..." Danzo glanced at Hiruzen Sarutobi and suddenly remarked. Ever since Naruto had appeared during the Uchiha massacre, Danzo had investigated him. He found that Naruto knew very few Ninjutsu, and in battle, he rarely displayed ninja methods. He mostly settled things with his fists.
"Danzo, put away your little schemes. Naruto isn't someone we can casually measure anymore." Hiruzen Sarutobi gave Danzo a stern look and growled.
