Sagisō: *holds all your Ocs and Kunai-point* ...you'd better...I have a creative plan with the rat in mind...
It's kinda cause Henshinas isn't really doing anything in terms of sheer offense. Once the Cloak goes up then honestly, Zaku, Kou and Ukon & Sakon don't factor into the fight anymore. They simply don't have the sheer physical ability to match that of a cloaked Jinchuriki. Kidomaru doesn't have the ability to either, but I think he'd be able to react to her at a bare minimum.Honestly I think Oto is overplaying its hand as well given the situation. But that is just my view of things. We'll see where it goes next.
And for reference, I'm talking about the type of speed Naruto used to blitz Orochimaru.
