As we all know hashi has battle with madara before. He having a hard time dealing with kyubi + EMS madara. And now will he have a chance against juubi + mokuton + rinenggan madara?
As we read the manga, they translate it to windcutting jutsu. But, don't you think it is a combination of wind and mist jutsu. Because kaze means wind and kiri means mist or fog. What do you think?
Now its clear that :
The mask man that control kyubi, attack konoha, fought yondaime hokage, meet itachi and manipulate yondaime mizukage is Uchiha Madara.
The mask man who manipulate nagato, lead akatsuki, and manipulate sasuke is Uchiha Obito.
