Have you ever seen Nagato absorbing Amaterasu? Why didn't he absorb Amaterasu? It's just the same thing. Itachi can catch Nagato in an illusion without eye contact. Also Itachi can catch Nagatos summon in a Genjutsu. Nagato, who will look through his summon with his own closed eyes, will see the illusion Itachi cast on the summon. It's an option.
And yes, he put another person under a Genjutsushiled. but how can he use a shield on himself? In fact Jiraiya caught three Pains in an illusion, also Itachi could do it.
Besides, the Rinnegan (Tendo) isn't stronger in Taijutsu than the Byakugan, since the Shinra Tensei isn't a Taijutsumove.
itachi ALWAYS use genjutsu when he fights. and he fights in free will during that time. not unlike nagato that was being controlled.so basically nagato doesn't have a choice on what to do.
lol we saw how itachi took on nagato's summon...it was through amaterasu not genjutsu. your logic fails when manga already show you how pain was affected by sound genjutsu..
here is what happened there, jiraiya caught 3 paths in genjutsu, nagato hears the sound but only the 3 where affected not all 7 of them.that it why in the genjutsu world only 3 paths are shown. so same can be said for visual genjutsu, nagato may see the genjutsu through his other paths but he will not get affected only the one itachi casted upon.
this has been said also over and over again..and I need to explain everything to newbie fanboys once in awhile..
dude hope you realize genjutsu shield is nagato's technique. ofcourse he can use it to himself.and why you said he doesn't have it when he fight jiraiya? remember he never knew jiraiya could use genjutsu.. that is why nagato was caught off guard.
LOL, and are you serious? still debating on hinata vs tendo?? dude, give up. hinata didn't even scratch tendo with her "superior" taijutsu moves.don't bother debating on this pls. rinnegan>>>>>>>>>>byakugan in every aspect.nuff said.
