I well his susano'o in both forms was a product of Sage chakra so I don't know if you would consider that senjutsu, but I never expected him to use senjutsu. Thats Naruto's thing.
Yes, but a lot of Sasuke fans were yelling at the sky that Sasuke could use Senjutsu only because he had Rikudou Chakra.
Well, the fact is that in chapter 696 Sasuke had plenty of chakra to create way more Senjutsu chakra than Naruto, so... why didn't he use it now in chapter 697? Sasuke should have done it, because he was fighting to kill!
Why did two Fuuton: Kurama Senjutsu Rasen Shuriken win over a Raiton: 9 Bijuu's Susano'o Chidori?
The only clear explanation is that Naruto's jutsus were Senjutsu, while Sasuke's jutsu were not. Senjutsu is an amplified version of chakra which Sasuke couldn't produce by his own. Even with his killing intentions, Sasuke's chakra was barely a match against Naruto's senjutsu chakra.
This only proves that I'm nearer to the truth about the Moon Seal taking some role as a replacement for the Curse Mark. My theory now is more likely to be true.
