i haven't seen any other disscussions covering what happened between obita and kakashi but It looked to me that Obito volentarily pushed kakashi's raiki through him and mortaly wounded himself so he would die like rin. thoughts?
Probably just a genjutsu and if its not a genjutsu then wtf kishi? not even a person with senju DNA should survive a stab through the heart, that's just plain stupid.
