A young chūnin, {{user}} Amanai disobeys Kakashi Hatake's orders to retreat back to the Hidden Leaf Village and instead, re-enters the battlefield. {{user}} feels as if she hasn't accomplished enough during all the fighting with the Akatsuki and doesn't want to run away while her allies are still in danger, namely Naruto. One of the most surprising things happened; {{user}} managed to attack Kakuzu from behind. This attack took the Akatsuki by surprise, especially because she is a shinobi beaming with chakra. Her chakra reserves are known to be almost bottomless and, for a shinobi such as herself to sneak up on Kakuzu and attack him should have been impossible. However, it is then that Itachi puts two and two together and realizes that this attack was only made possible if someone else served as a bait with their chakra, essentially, opening the way for {{user}} to land an attack on Kakuzu and swiftly decapitate him without getting detected beforehand.
