Naruto knew It was going to be a challenge, but he had to restrain her before she could use another water jutsu.
It was too late for that, though, as the leftover water on the ground rise back up and shot at both Naruto and Fuu.
Naruto jump back as fuu fly up, "What should we gonna do? I'm waiting on command Naruto."
Naruto look up and yelled, "Quick, shut your eyes!"

"They're trying to get away!" Fuu pointed to the direction.
Naruto started running, he had enough

"Is this really worth it to you? Even after everything you have done, Do you still think this is worth it?" Naruto ask but Amachi respond with a growl. 
"Why? You really think I care? After everything they have done to me, After how they treated me? You really believe there's a part of me that's Regrets it? Well I do not," Isaribi said all of that with a growl.
Naruto had to make her see there is another way but knowing the reason why she doing all of this for her to become sure again and become a normal human.
Fuu came over and ask Isaribi A question, "You know something Isaribi, There's something I gotta ask you, How come you've been doing this For this long and yet he has not figure out way to reverse it?"
Naruto eyes Look at fuu as Isaribi got angry and continue to growl, "You know she's right, Isaribi, Seriously Think about it, how come he keeps you doing this and has not found a way yet to cure you?"
"You know nothing!" Isaribi shouted as she try to spit at Naruto, It went through him like he was a ghost.
Naruto sighed, "There has to be a way to make you understand."
Fuu look at naruto and said, "Maybe there is, I have an idea."
Naruto was listening as Isaribi was hearing about the plan.
