The Land of Water.
Naruto, Zabuza, and Haku walked toward Kirigakure together.
From the Nanometer Robots' feedback, Naruto knew that Obito had only recently entered the Land of Water himself. He had yet to start causing trouble.
If he wanted Zabuza to become Mizukage, he would have to make him Kirigakure's hero.
How did someone become a hero? By defeating a villain no one else could defeat, of course!
And that villain's role would fall to Obito.
Not that he needed to act the part. He already was a villain!
When they reached the jungle near Kirigakure, Zabuza looked at the village he had only recently left and asked Naruto beside him, "Boss Mei Zheren, what do we do next? Fight our way straight into Kirigakure?"
Naruto answered with just one word: "Wait!"
Naruto took out his phone again, opened the livestream, and checked on Obito's progress in causing trouble.
Elsewhere.
Obito had also arrived near Kirigakure.
In truth, he had returned to Kirigakure not only because the genjutsu on the Fourth Mizukage had become somewhat unstable, but also because... he needed to rescue Kisame.
As soon as the Fourth Mizukage regained his senses, he had severely injured Kisame.
Although he had been under genjutsu all that time, the Fourth Mizukage knew exactly what he had done.
So... Kisame naturally became the first target of his anger.
However, the Fourth Mizukage had not killed Kisame. He had no authority to decide Kisame's fate, so he had locked him up instead.
The elders of the Elders Council also advised against disposing of Kisame, because no one else in Kirigakure could currently wield Samehada.
Obito's first objective was to rescue Kisame. As for the Fourth Mizukage? He no longer intended to control him. He would simply kill him.
