Risa: SASUKE 

Sasuke: RISA ?, GET OUT OF HERE IT'S DANGEROUS !!!!!!

Risa : over my dead body I will !

Risa runs forward using her lighting blast to strike itachi , itachi tried moving to the left to dodge it but sasuke was faster and when he did move sasuke knocked him unconscious , Risa faced sasuke :

Risa: we should go back and help Naru and Hina , right sasu?

Sasuke : yeah , it hurts though I still kind of love my elder brother

Risa: there is nothing we can do now, let's go help out with Naru and hinata

Meanwhile

Hina : you are going to get your ass kicked !

Hina dodged Menma blade and used the 10 unsealed lions to attack knocking him unconscious
