oh my gosh, my two favorite girl characters fighting, say it ain't so. well, as long as you're amused with the idea. i really haven't watched much of the later seasons, so i can't gauge them for where they're currently at. i think Sakura could win if it were season 1.
normally i'd say anyone could beat sakura... but hinata?? really???? she's just so cute and basically harmless. i'm gonna have to say sakura. hinata just doesn't have good enough attack
