it's just seeming like super monstrous strength rather than techniques n all, soooo not so up in my book, but then again her developing new n strong techniques all of a sudden would be just unbelievable in her case cox she never had them before, i mean if she really had something up her sleeves then the best time to show it would have been in the pain attack on the konoha village...... i mean what kind of a person would just stand and watch while the village is getting pulverised when she can do even the smallest thing about it..... soo bad judgement on kishi's side maybe??!! just my opinion
