I just don't understand the Naruto community. From all the posts I've read, most of you people seem to hate this series more than you love it. Every single thing Kishi does (Some are pretty bull shit I will admit, but I digress) you all jump quick to call plot holes, BS, ass pulls, etc so fast without even thinking of how this all happen and why. Kishimito isn't the type of person to not explain himself vaguely through flashbacks and past chapters. From what I can see, Obito used his Kamui in his spirtial form and used Kakashi as a medium to give him his Sharingans. All the Sharingan is a ocular ball of chakara. We've seen this happen many times with Minato, Kushina ect. All of them used some sort of Jutsu from the after life so I don't see how any of you can call BS on this without contradicting all the other characters doing the exact same damn thing. Kakashi having Perfect Susanoo is already a given because both MS eyes were trained by Kakashi and Obito over these years. That is all that is required to obtain that jutsu. Now how does he have perfect Sussano you say without EMS? Well Kishimoto never even stated you needed EMS to use it. Sasuke was almost at the final stages of going into a perfect Susanoo when he fought Danzo and so was Madara when he was fighting Hashirama. From what I can understand now, the perfect sussasno comes from the emotions and will of the user. Kakashi wanted to be strong enough to protect his students, thus the sharigans responded with the final Susanoo form to do so. It's farfetched, and probably would be considered fanfiction, but this is just my way of thinking. Or he just copied it, that works too.
