Naruto finally joins the battle on the bridge. Sasuke is having a hard time fighting Hakuand is trapped in Haku's Demonic Mirroring Ice Crystals. Kakashi is unable to help them, as he is dealing with Zabuza while protecting Sakura and Tazuna.
He orders Sasuke to continue attacking the mirrors from within while Naruto attacks from outside. Naruto is oblivious to Haku's jutsu and enters the cage of ice mirrors. Sasuke tells Naruto that he is a complete loser and that now they are both trapped. After a little arguing, both agree to work together.
Haku reveals that he doesn't like to kill his enemies but will do so if he must. Aika hid behind Kakashi and Zabuza laughed.
"You call that a ninja, that girl is far from it" Zabuza laughed
"Aika don't be afraid, just because enemies seem scary you can still win based on the techniques you use. You won't die, I promise we'll protect you" Kakashi said
"Don't believe that girl, your name will just be added to your village's KIA stone" Zabuza said
"Hey don't say that!" Naruto shouted "I won't let anybody touch my sister! She's stronger then you'll ever be!"
Zabuza laughed, Aika smiled a bit and whispered "Naruto"
