Is Obito on Sage Mode? Recently in the manga, Uchiha Obito said that he sensed Sasuke concentrating chakra in his left eye and poof! He quickly defended himself in an instant with slight similarity to Naruto's Sage Mode, that's why I wonder if he is in Sage Mode. If not, where did his sensory ability come from?



Update:
Here's a proof of his transformation from Naruto Episode 640 Page 14:
Something that I completely forgot. During Sasuke's battle with Deidara, Sasuke mentioned that using his Sharingan he can see chakra, so even Obito should be able to do the same, when Sasuke concentrated his chakra on his left eye, Obito could see it, thus he dodged it. He need not be in Sage Mode to accomplish that.
