Long ago Kakashi said Sakura has a genjutsu potential, but so far.. only in anime (or movie? I forgot. I never watch it anyway..) that actually showed that she used a genjutsu during fight. It was named Sakura Fubuki no Jutsu (Sakura's Petal Storm Technique), in which Sakura's body turned into a storm of cherry blossom petals. I think it was a cool jutsu <3.
I hope Kishi will start Sakura's development soon.
i love Sakura, really.. So, do not make her crying all the time, Kishi... Please?
