Nope.You know what the best part is, he couldn't fly after he fought in the Kaguya arc, don't give me that he flew on the moon shit because that would make Armstrong a Sage too by simply jumping around on it you dumb fuuk. He doesn't have RSM anymore. Your denial is the cause of poor writing by the author who should have provided more details when unveiling characters, RSM entails the Chakra of all nine bijuus residing inside you and the goudodamas floating behind you. In the last he has neither, in the Gaiden he still has neither, so get the **** out of here with that theory.
Naruto was in rsm when he kicked the truth seeking orbs
Databook says
"Kicking truth seeking orb surpassing kurama mode"
On the page for rsm
And Even shows a picture
Is you stupid
