Under Tsunade's apprenticeship, she learns to use her chakra to heal wounds and build her chakra in her fists, giving her superhuman strength.
I really like how Sakura has developed into such a strong and beautiful character. I guess she's still highly infatuated with Sasuke, but I wonder if she'll ever return Naruto's feelings for her? Guess we'll have to wait and see. Beautiful cosplay though!
