with katsuya ,she maybe wins
katsuya fights choji ,sakura fights shikamaru and ino is useless since her only attack jutsu doesnt work against sakura as it was showed in part 1
so sakura beats shikamaru ,and even if she was cought by his shadow ,katsuya would just attack him with her acid so he will be forced to cancel his shadow to avoid the acid
then she and katsuya will beat choji
Choji takes Katsuyu while Ino distracts Sakura then Shikamaru catches her with Kagemane and either Ino stabs her with a kunai or Choji steps on her. Shikamaru will feel the pain Sakura feels but i don't think he will die as you can't copy someone dying...right?
