“I activated the Earth Chain Ice I cast on you,” Kahyo said, turning toward
Kakashi. “If you don’t want to be frozen, the only thing you can do is keep
molding your chakra and sending that heat around your body.”
“I see. So people who can’t manipulate their chakra end up frozen right
away, huh?”
“As long as you are using your chakra to suppress the Earth Chain Ice, you
won’t be able to use it for any other jutsu. In other words, Hatake Kakashi,”
she paused, “you are just a regular person now.”
“So it was you. The one who froze everyone other than Rahyo, it was
you.”
“I’m the only one who can use Earth Chain Ice.”
