She doesn't talk much so we can't really know her view on things, so basicly we don't know who she is personality wise
her stupidity.
Opps did I just bash her? Tee hee
Idk if this counts as a flaw, but imo it's the fact that she isn't as good as just about every other villain was
She's a mute.
When did someone change the enviorement like she did in Naruto?she's socially awkward and most of her abilities are so similar to those that we have seen before that they barely stand out
I wouldn't say she has flaws, she's just lacking as a character and even more as a main villain. She doesn't interact much with characters and when she does its not villainous in the slightest.
Caressing your opponents face while crying is not villainous.
