Tell us the manga chapter and/or page, Itachi once used Tsukuyomi without activating his MS, and besides did you see Obito's left while he was crushed?Im sry idk how to post scans......
I don't think nobody has a answer for this and sry if its been discussed .
Kakashi has to use MS to use kamui, why?
Obito used it to slip thru the bolder that crushed him but didn't awaken MS till after rin died...
I think i fell in a plot ditch
